What is the gravitational force on a 35.0 kg object standing on the Earth’s surface?

Answer:

If the fire truck is parked 25 feet away from the high rise and the ladder on the truck reaches 100 feet, we can use the Pythagorean theorem to find out how high up the high rise the ladder can reach.

Let's assume that the height the ladder can reach is "x". Then, we can set up the following equation:

25^2 + x^2 = 100^2

Simplifying this equation, we get:

625 + x^2 = 10000

Subtracting 625 from both sides, we get:

x^2 = 9375

Taking the square root of both sides, we get:

x = sqrt(9375)

x ≈ 96.81

Therefore, the ladder on the fire truck can reach a height of approximately 96.81 feet up the high rise

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.

The value of d/c = 8, when the given graph represents the equation f(x) = 5.4321*(2)ˣ, and A (1, c), and B (4, d) pass through the graph.

The graph of an equation passes through all the points that satisfy the given equation. The graph shows a curve joining all those points.

In the question, we are given a graph and its equation f(x) = 5.4321*(2)ˣ.

We are given the coordinates of two points on graphs A: (1, c) and B: (4, d).

We know that any point of the form (x, y) which passes through the graph of the equation, satisfies the equation.

∴ A (1, c) and B (4, d) satisfies the equation f(x) = 5.4321*(2)ˣ.

∴ c = 5.4321*(2)¹ = 5.4321 * 2

d = 5.4321*(2)⁴ = 5.4321 * 16

∴ d/c = (5.4321*16)/(5.4321*2) = 16/2 = 8.

∴ The value of d/c = 8, when the given graph represents the equation f(x) = 5.4321*(2)ˣ, and A (1, c), and B (4, d) pass through the graph.

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)

To find the probability of C given F, we need to divide the frequency in the cell where C and F intersect by the total frequency in the row where F is located:

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.

                                          = [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)]

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.

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.

NB: LEFT-HAND SIDE IS EQUAL TO THE RIGHT-HAND SIDE

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.

The perimeter of the pond is 2.92 meters.

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.

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.

The area of the circle is approximately 346.36 square centimeters.

Area is a mathematical concept that refers to the amount of space that is inside a two-dimensional shape or surface. It is typically measured in square units, such as square meters (m² or square centimeters (cm²).

The diameter of a circle is the distance across the circle passing through its center. It is twice the length of the circle's radius.If you know the diameter of a circle, you can calculate its radius by dividing the diameter by 2: radius = diameter/2

In the given question,

The diameter (d) of a circle is the distance across the circle passing through the center.

If the diameter of the circle is 21 cm, then the radius (r) of the circle (which is half of the diameter) is:

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)

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:

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.

99% confidence interval is that the true population proportion of adults who say national identity is strongly tied to birthplace in Country A is between 30.7% and 37.3%.

The confidence interval is a set of values that, with a given level of certainty, contains the real population parameter. The likelihood that the genuine population parameter falls inside the interval is represented by the degree of confidence. In this instance, we created 99% confidence intervals for the percentage of individuals in each demographic who claim that national identity is highly correlated with birthplace. This indicates that 99% of the intervals we build would include the genuine population percentage if the survey were to be repeated numerous times.
