Given is to find the diameter and height of the tin can.
Assume the density of coffee as {ρ}. We can write the volume of the tin can as -
Volume = mass x density
Volume = 750ρ
We can write -
πr²h = 750ρ
r = √(750ρ/πh)
D = 2r
D = 2√(750ρ/πh)
Now, we can write the circumferance as -
C = 2πr
C = 2π√(750ρ/πh)
Therefore, we can write the diameter and circumferance of base as -
D = 2√(750ρ/πh)
C = 2π√(750ρ/πh)

generally, cold fronts move fast er than warm fronts generally, cold fronts have steeper slopes generally, precipitation cover s a much broader area with a cold front especially in winter, cumuliform clouds are more often associated with cold fronts
Cold fronts generally move faster than warm fronts because cold air is denser and thus, moves more quickly. Precipitation with a cold front typically covers a broader area, especially during the winter.
On the other hand, warm fronts move more slowly as they are characterized by the gradual lifting of warm air over colder air. Cold fronts also typically have steeper slopes than warm fronts. This is because the leading edge of a cold front is more abrupt.
With a steep rise in the cold air mass. In contrast, the leading edge of a warm front has a gentler slope as the warm air gradually rises over the colder air.

The probability of P(B U E) is 0.5984, the probability of the complement of G (i.e. Gᶜ) is 0.6818, and the probability of C given F is 0.4706
To find the probability P(B U E), we need to add the frequencies in column B and row E, but since the cell where they intersect has already been counted in both, we need to subtract it once. Therefore:
P(B U E) = (6+13+17) + (15+20+10+45) - 43 = 73
Then we divide by the total number of observations:
P(B U E) = 73/122 = 0.5984 (rounded to four decimal places)
To find the probability of the complement of G (i.e. Gᶜ), we need to subtract the frequency in the cell where G and Total intersect from the total number of observations:
P(Gᶜ) = 1 - 39/122 = 0.6818 (rounded to four decimal places)

There is a total of 360 students and teachers at a school. A trip is organized and 65% of the students and teachers bought tickets to go on this trip.
(a) Work out how many of the students and teachers bought tickets to go on the trip.
The number of teachers,the number of male students and the number of female students who bought tickets to go on the trip are in the ratios 1:3:5 .
(b) Calculate the number of female students who bought tickets to go on the trip.
All the male students who bought tickets went on the trip but 4 of the female students who bought tickets did not go on the trip.
(c) Find the ratio of the number of male students who went on the trip to the number of female students who went on the trip.
Answer: Below :)
Step-by-step explanation:
(a) The percentage of students and teachers who bought tickets to go on the trip is 65%. So the number of students and teachers who bought tickets can be found by multiplying the total number of students and teachers by 65%:
65/100 x 360 = 234
Therefore, 234 students and teachers bought tickets to go on the trip.
(b) Let the number of teachers who bought tickets be x. Then the number of male students who bought tickets is 3x, and the number of female students who bought tickets is 5x.
The total number of students and teachers who bought tickets is:
x + 3x + 5x = 9x
We know that 234 students and teachers bought tickets, so we can set up the following equation:
9x = 234
Solving for x, we get:
x = 26
So the number of teachers who bought tickets is 26, the number of male students who bought tickets is 78 (3x), and the number of female students who bought tickets is 130 (5x).
However, 4 of the female students who bought tickets did not go on the trip, so the actual number of female students who went on the trip is:
130 - 4 = 126
(c) The ratio of the number of male students who went on the trip to the number of female students who went on the trip is:
78/126
Simplifying this ratio by dividing both numerator and denominator by 6, we get:
13/21
Therefore, the ratio of the number of male students who went on the trip to the number of female students who went on the trip is 13:21.

Answer:
Area = 559.17 square feet
Perimeter = 94.26 ft
Step-by-step explanation:
Make sure all the units are the same and consistent.
r = radius of semi-circle
= [tex]\frac{Diameter}{2}[/tex]
= [tex]\frac{18}{2}[/tex] ft
= 9 ft
Area of composite figure = Area of rectangle + Area of semi-circle:
= [Length × Breadth] + [[tex]\frac{1}{2}[/tex] × (Area of circle)]
= [24 ft × 18 ft] + [[tex]\frac{1}{2}[/tex] × ([tex]\pi r^{2}[/tex])]
= 432 [tex]ft^{2}[/tex] + [[tex]\frac{1}{2}[/tex] × ([tex]\pi 9^{2}[/tex])] [tex]ft^{2}[/tex]
= 432 + [[tex]\frac{1}{2}[/tex] × (3.14) ×(81)]
= 559.17[tex]ft^{2}[/tex]
Perimeter of composite figure =
Circumference of semi-circle + 3 outer sides of rectangle:
= [[tex]\frac{1}{2}[/tex] × [tex]2\pi r[/tex]] + [24 + 18 + 24]

What is the degree measure of the smaller angle between the hour and minute hands of the clock at 5:10 PM?
F. 110°
G. 105°
H. 100°
J. 95°
K. 90°
Answer:
At 5:10 PM, the minute hand is at the 2-minute mark, and the hour hand is between the 5 and 6 marks, closer to the 5.
The minute hand is at the 2-minute mark, which is 1/30th of the way around the clock face. So, the minute hand has traveled 1/30th of a full circle, which is 360°, or 12°.
The hour hand is between the 5 and 6 marks, closer to the 5. It has passed the 5 and is 1/6th of the way to the 6. Since the clock face is divided into 12 hours, 1/6th of the way from 5 to 6 is 5 + 1/6 = 5.166... hours.
Each hour mark represents 30 degrees, so the hour hand has traveled 5.166... × 30 = 155 degrees from the 12 o'clock position.
The smaller angle between the hands is the angle between the hour hand and the minute hand that is less than 180 degrees. We can find this angle by subtracting the smaller angle between the hands from 360 degrees.
To find the smaller angle between the hands, we can subtract the angle traveled by the hour hand from the angle traveled by the minute hand:
12° - 155° = -143°
The negative sign indicates that the angle is measured clockwise from the 12 o'clock position. To find the positive angle between the hands, we add 360 degrees:
360° - 143° = 217°
Therefore, the degree measure of the smaller angle between the hour and minute hands of the clock at 5:10 PM is approximately 217 degrees. Since this value is not one of the answer choices, we can round it to the nearest choice, which is F. 110°
A pond in the shape of a right-angled triangle is shown below. Calculate the perimeter of the pond. Give your answer in metres to 1 d.p. 1.46 m 100 73°
The perimeter of the pond is 2.92 meters.
What s a right-angle triangle:
A right-angled triangle is a triangle in which one of the angles measures exactly 90 degrees, also known as a right angle.
The side opposite the right angle is called the hypotenuse, and the other two sides are called the legs.
The perimeter of a right-angled triangle is the sum of the lengths of its three sides.
Here we have
The Hypotenuse of the triangle is 1.46 m
The angle between hypotenuse and perpendicular height = 73°
From triagonometric ratios,
=> cos A = Perpendicular height/ Hypotenuse.
=> cos (73) = Perpendicular height/1.46
=> Perpendicular height = 1.46 × 0.29 = 0.42 m
As we know from Pythagoras' theorem,
Hypotenuse² = side² + side²
Side = √Hypotenuse² - side²
= √[(1.46)²- (0.42)²] = 1.04
Therefore, the sides of the pond are 1.46 m, 0.42 m, and 1.04
Hence, perimeter of the pond = 1.46 + 0.42 + 1.04 = 2.92 meters
Therefore,
The perimeter of the pond is 2.92 meters.

One side of the triangle is 4 cm, and the sum of the other two sides is equal to a whole number of cm. What is the smallest possible perimeter of the triangle?
F. 9 cm
G. 10 cm
H. 11 cm
J. 15 cm
K. 17 cm
Answer:
9 cm
Step-by-step explanation:
By the Triangle Inequality, any two sides of a triangle must be greater than the remaining side.
In order to minimize the perimeter, we will assume that 4 cm is the longest side.
Thus, the two remaining sides must be greater than 4.
Since we are given that the sum of the two remaining sides is a whole number, the smallest whole number value greater than 4 is 5.
Hence, the smallest perimeter possible 9 cm.
△CDE∼△PQR. CD=9 m, EC=15 m, PQ=15 m. What is the length of RP?

A box containing 5 balls costs $8.50. If the balls are bought individually, they cost $2.00 each. How much cheaper is it, in percentage terms, to buy the box as opposed to buying 5 individual balls?
Answer: The total cost of buying 5 balls individually is $2.00 x 5 = $10.00.
The box costs $8.50, which means it is $10.00 - $8.50 = $1.50 cheaper to buy the box.
To calculate the percentage difference, we can use the formula:
% difference = (difference ÷ original value) x 100%
In this case, the difference is $1.50, and the original value is $10.00.
% difference = ($1.50 ÷ $10.00) x 100%
% difference = 0.15 x 100%
% difference = 15%
Therefore, it is 15% cheaper to buy the box than to buy 5 individual balls.

certain can of soda contains 60 milligrams of caffeine. The caffeine is
eliminated from the body at a rate of 15% per hour. What is the half-life of the
caffeine? That is, how many hours does it take for half of the caffeine to eliminated
from the body?
Answer:
3.33 hours
Step-by-step explanation:
you have a total of 60mg, it is asked how much hours it takes to remove half the caffeine which is 30mg
1 hour removes 15%, 15% of 60 is 9g
(15/100×60) = 9
now it removes only 9g in an hour, we have to find out how long (hours) it'll take to remove 30g
30÷9= 3.33 hours
Suppose parametric equations for the line segment between (8,-2) and (9,-2) have the form:

A parametric equation is one where the x and y coordinates of the curve are both written as functions of another variable called a parameter; this is usually given the letter t or θ . And the value of a= 8, b= 1, c= -2 and d= 0.
Equation of this form is known as a parametric equation; it uses an independent variable known as a parameter (often represented by t) and dependent variables that are defined as continuous functions of the parameter and independent of other variables.
You require 4 independent solutions because there are 4 unknowns. You can put two equations at each end point if you know t at each end point. (one for the x value and one for the y value).
At (8,-2), time is equal to zero as follows: 8 = a + bt = a + b(0) a = 8 -2 = c + dt = c + d(0) c = -2
At (9,-2), t = 1 because 9 = a + bt = 8 + b(1) b = 1 and -2 = c + dt = -2 + d(1) d = 0.

Milan bought packs of pencils. Each pack has pencils. Write an equation to represent the total number of pencils that Milan bought.
Answer:
total number of pencils = p × n
total number of pencils = 3 × 12 = 36
Step-by-step explanation:
Let's break down the problem into its components. Milan bought packs of pencils, so we can represent the number of packs he bought with the variable "p". We also know that each pack has "n" number of pencils, so the total number of pencils Milan bought can be found by multiplying the number of packs with the number of pencils in each pack.
In mathematical notation, this can be written as:
total number of pencils = number of packs × number of pencils in each pack
or, using the variables we defined:
total number of pencils = p × n
So, if Milan bought 3 packs of pencils and each pack had 12 pencils, the total number of pencils he bought would be:
total number of pencils = 3 × 12 = 36
What is the gravitational force acting on a 70.0 kg object standing on the Earth’s surface?
Answer:
What is the gravitational force acting on a 70.0 kg object standing on the Earth’s surface?
Step-by-step explanation:
The gravitational force acting on a 70.0 kg object standing on the Earth’s surface can be calculated using the formula:
F = G * (m1 * m2) / r^2
Where:
F = gravitational force
G = gravitational constant (6.6743 x 10^-11 N*m^2/kg^2)
m1 = mass of the first object (in this case, the mass of the Earth)
m2 = mass of the second object (in this case, the mass of the object, 70.0 kg)
r = distance between the centers of the two objects (in this case, the radius of the Earth, which is approximately 6,371 km)
Using the values above, we can calculate the gravitational force as follows:
F = (6.6743 x 10^-11 N*m^2/kg^2) * (5.97 x 10^24 kg * 70.0 kg) / (6,371,000 m)^2
F = 686.6 N
Therefore, the gravitational force acting on a 70.0 kg object standing on the Earth’s surface is approximately 686.6 N.

A shop is having a 40% sale. A jumper originally costs £50. How much will it be in sale?
Answer:
30 pounds
Step-by-step explanation:
Since the jumper costs 50 pounds, the decimal for the number will be:
50.
To find ten percent of the number, you move the decimal one time to the LEFT.
Therefore, 10% of 50 pounds will be 5 pounds. To find 40%, we simply will multiply the 10% amount by 4.
40% of 50 will be:
20
Therefore, the jumper will have 20 pounds off.
Since the original cost is 50 pounds, we simply will just subtract 50 - 20:
50 - 20 = 30
The jumper will cost 30 pounds with the sale deal.
Which statement explains how you could use coordinate geometry to prove that
quadrilateral ABCD is a rectangle?
You could use coordinate geometry to prove that ABCD is a rectangle by checking the side lengths, slope, and diagonal lengths using the distance and slope formulas.
What is a rectangle?
A rectangle is a quadrilateral with four right angles, meaning each of its angles measures 90 degrees. It is a type of parallelogram where opposite sides are parallel and equal in length. The opposite sides of a rectangle also have equal length, and its diagonals bisect each other. In addition to its geometrical properties, rectangles are commonly used in various fields for their symmetry, regularity, and practicality, such as in architecture, engineering, and graphic design.
To prove that quadrilateral ABCD is a rectangle using coordinate geometry, one possible method is to use the properties of a rectangle. Specifically, a rectangle is a quadrilateral with all four angles equal to 90 degrees and opposite sides equal in length.
So, to use coordinate geometry to prove that ABCD is a rectangle, you could:
Assign coordinates to the four vertices of ABCD, say A(x1,y1), B(x2,y2), C(x3,y3), and D(x4,y4).
Use the distance formula to calculate the lengths of each side of the quadrilateral, i.e., AB, BC, CD, and DA.
Use the slope formula to find the slopes of the four sides. Since opposite sides of a rectangle are parallel, their slopes will be equal.
Use the distance formula again to calculate the diagonal lengths, AC and BD.
Check that the opposite sides are equal in length and parallel, and that the diagonals are equal in length. If all these conditions are satisfied, then ABCD is a rectangle.
Therefore, you could use coordinate geometry to prove that ABCD is a rectangle by checking the side lengths, slope, and diagonal lengths using the distance and slope formulas.

The probability that Sara whassell four extended warranties tomorrow is___
(Round to four decimal places as needed.)
Answer:
The probability that Sara whassell four extended warranties tomorrow is 0.1046
Step-by-step explanation:
Please hit brainliest if this helped! If you have any questions, please comment.
We can use the Poisson probability formula to calculate the probability of selling 4 extended warranties tomorrow:
P(X = k) = (e^(-λ) * λ^k) / k!
where λ is the average number of extended warranties sold per day and k is the number of extended warranties sold.
In this case, λ = 2.7 and k = 4. So, plugging in the values, we get:
P(X = 4) = (e^(-2.7) * 2.7^4) / 4!
P(X = 4) ≈ 0.1046
Therefore, the probability that Sara will sell four extended warranties tomorrow is approximately 0.1046, rounded to four decimal places.

r = d/2 = 21/2 = 10.5 cm
The formula for the area (A) of a circle is:
A = πr²
where π (pi) is a mathematical constant that represents the ratio of the circumference of a circle to its diameter, approximately equal to 3.14159.
Substituting the value of r into the formula, we get:
A = π(10.5)² A = 346.36 cm² (rounded to two decimal places)
Therefore, the area of the circle is approximately 346.36 square centimeters.

Andy has 4 red cards, 3 blue cards, and 2 green cards. He chooses a card and replaces it before choosing a card again. How many possible outcomes are in the sample space of Andy's experiment?
A) 18
B) 9
C)81
D)3
Answer: C) 81
Step-by-step explanation:
Since Andy chooses a card and replaces it before choosing another card, each choice is independent and the total number of possible outcomes is the product of the number of choices for each card.
There are 4 red cards, 3 blue cards, and 2 green cards, so there are a total of 4+3+2=9 cards to choose from.
For each choice, Andy has 9 options. Since he does this twice, the total number of possible outcomes is:
9 x 9 = 81
Therefore, the answer is C) 81.
write each expression without the absolute value symbol
The piecewise function forms of the absolute values are, respectively:
Case 1 (|(x - 19) + 11|)
x - 8 for x > 8
0 for x = 8
8 - x for x < 8
Case 2 (|14 - (x - 6)|)
- x + 22 for x < 22
0 for x = 22
x - 22 for x > 22
Case 3 (|14 - (6 - x)|)
x + 8 for x > - 8
0 for x = - 8
- x - 8 for x < - 8
How to rewrite absolute value functionsIn this problem we find three cases of absolute values represented in a single expression. Herein we need to determine an alternative form without "bar" operators.
This form is represented by a piecewise function derived from definition of absolute value:
|x - a| = x - a for x > a|x - a| = a - x for x < a|x - a| = 0 for x = a.Then, we find the following definitions for each of the three cases:
Case 1
|(x - 19) + 11| = |x - 8|
|x - 8| = x - 8 for x > 8
|x - 8| = 0 for x = 8
|x - 8| = 8 - x for x < 8
Case 2
|14 - (x - 6)| = |- x + 22|
|- x + 22| = - x + 22 for x < 22
|- x + 22| = 0 for x = 22
|- x + 22| = x - 22 for x > 22
Case 3
|14 - (6 - x)| = |x + 8|
|x + 8| = x + 8 for x > - 8
|x + 8| = 0 for x = - 8
|x + 8| = - x - 8 for x < - 8

The statement " all of the following are things you can do when faced with any ethical dilemma as a managerial accountant except: always contact the board of directors first" is false because contacting the board of directors is not always necessary or appropriate when faced with an ethical dilemma as a managerial accountant
Contacting the board of directors is not always necessary or appropriate when faced with an ethical dilemma as a managerial accountant. While the board of directors may need to be informed in some situations, there are other steps that can be taken depending on the specific circumstances. For example, seeking guidance from a supervisor, consulting with a professional organization, or seeking legal advice may be more appropriate in some cases. The appropriate course of action will depend on the specific situation and ethical principles involved.

Amelia knits 7 sweaters and 9 scarves to give to her friends. She uses 9 balls of yarn to make each sweater and 4 balls of yarn to make each scarf. How many balls of yarn does Amelia use in all?
Amelia uses 99 balls of yarn in all to make the sweaters and scarves.
What is addition ?
Addition is a basic mathematical operation that combines two or more quantities to find a total or a sum. It is denoted by the symbol "+" and is usually taught in elementary school. In addition, the order of the numbers does not matter, meaning that you can add them in any order and still get the same result. For example, 3 + 5 is the same as 5 + 3, and the answer is 8 in both cases.
According to the question:
To find the total number of balls of yarn that Amelia uses, we can start by finding the total number of balls of yarn she uses to make the sweaters and scarves separately, and then add those amounts together.
To make 7 sweaters, Amelia uses 7 x 9 = 63 balls of yarn.
To make 9 scarves, Amelia uses 9 x 4 = 36 balls of yarn.
Adding these together, we get:
63 + 36 = 99
So, Amelia uses 99 balls of yarn in all to make the sweaters and scarves.
