Answer:
235.5
Step-by-step explanation:
3.14x2.5^2x12
3.14x6.25x12
19.625x12
235.5
Answer :
240 ft³⠀
Explanation :
We know,
[tex]{ \longrightarrow \qquad{\boldsymbol {\pmb{ Volume_{(cylinder)} = \pi {r}^{2} h \: }}}}[/tex]
Where,
r is the radius of the cylinder. Here, diameter is 5 ft, so the radius will be 2.5 fth is the height of the cylinder. Here, h is 12 ft Here, we will take the value of π as 3.14 approximately .⠀
Substituting the values in the formula :
[tex]{ \longrightarrow \qquad{ { \sf{ Volume_{(cylinder)} = 3.14 \times ({2.5})^{2} \times 12 \: }}}}[/tex]
⠀
[tex]{ \longrightarrow \qquad{ { \sf{ Volume_{(cylinder)} = 3.14 \times 6.25 \times 12 \: }}}}[/tex]
⠀
[tex]{ \longrightarrow \qquad{ { \sf{ Volume_{(cylinder)} = 3.14 \times 75 \: }}}}[/tex]
⠀
[tex]{ \longrightarrow \qquad{ \boldsymbol { \pmb{ Volume_{(cylinder)} = 235.5 \: }}}}[/tex]
⠀
Therefore,
The volume of the cylinder is 240 ft approxiamtely.Drake’s monthly outlay include a $70 phone bill and a $120 car assuming he makes $400 a month, how much does he have to spend after paying his bills?
The solution is, $210 does he have to spend after paying his bills.
What is Subtraction?Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.
here, we have,
given that,
Drake’s monthly outlay include a $70 phone bill and a $120 car assuming he makes $400 a month,
i.e. we get,
Drake’s monthly outlay include a $70 phone bill and a $120 car.
so, total spend = $ 120 + 70
= $190
now, we have to find how much does he have to spend after paying his bills.
so, we have to subtract 190 from 400
i.e. 400 - 190
=210
Hence, $210 does he have to spend after paying his bills.

Determine whether the sequence is arithmetic, geometric, or neither: 20,17,14,11
==================================================
Explanation:
Add -3 to each term to get the next term. This is the same as subtracting 3 from each term. In this case, the common difference is d = -3.
The first term is a = 20
---------
The nth term formula for the arithmetic sequence is
a(n) = a+d(n-1)
a(n) = 20+(-3)(n-1)
a(n) = 20-3n+3
a(n) = -3n+23
If we plug in n = 1, we would get a(n) = 20. Plug in n = 2 to get a(n) = 17. And so on. This helps confirm we have the correct nth term formula.

The soccer team's shirts have arrived in a big box, and people just start grabbing them, looking for the right size. The box contains 6 medium, 10 large, and 10 extra-large shirts. A player wants a medium for himself and one for his sister. Find the probability of each event described. Complete parts a through d below.
a) Probability of getting a medium shirt for the player ≈ 0.0385
b) Probability of getting a medium shirt for the player's sister ≈ 0.0385
c) Probability of getting a medium shirt for both the player and his sister ≈ 0.00148225
d) Probability of getting either a medium, large, or extra-large shirt ≈ 0.0385.
Here, we have,
To find the probability of each event, we first need to determine the total number of shirts in the box and the number of shirts that satisfy each event.
a) Probability of getting a medium shirt for the player:
Total number of medium shirts = 6
Number of medium shirts needed for the player = 1
Probability = (Number of medium shirts needed) / (Total number of shirts) = 1 / (6 + 10 + 10) = 1 / 26 ≈ 0.0385
b) Probability of getting a medium shirt for the player's sister:
Total number of medium shirts = 6
Number of medium shirts needed for the player's sister = 1
Probability = (Number of medium shirts needed) / (Total number of shirts) = 1 / (6 + 10 + 10) = 1 / 26 ≈ 0.0385
c) Probability of getting a medium shirt for both the player and his sister:
Since the two events are independent (one person getting a medium shirt does not affect the other's chance of getting a medium shirt), we can multiply the probabilities of each event:
Probability = Probability of player getting a medium shirt * Probability of player's sister getting a medium shirt ≈ 0.0385 * 0.0385 ≈ 0.00148225
d) Probability of getting either a medium, large, or extra-large shirt:
Total number of medium, large, and extra-large shirts = 6 + 10 + 10 = 26
Number of shirts needed = 1 (for the player or his sister)
Probability = (Number of shirts needed) / (Total number of shirts) = 1 / 26 ≈ 0.0385
To summarize:
a) Probability of getting a medium shirt for the player ≈ 0.0385
b) Probability of getting a medium shirt for the player's sister ≈ 0.0385
c) Probability of getting a medium shirt for both the player and his sister ≈ 0.00148225
d) Probability of getting either a medium, large, or extra-large shirt ≈ 0.0385.

Total consumption of fruit juice in a particular country in 2006 was about 1.85 billion gallons. The population of that country in 2006 was 300 million. What was the average number of gallons of fruit juice consumed per person in the country in 2006?
Given :
Population of country in 2006 , P = 300 million.
Consumption of fruit juice in 2006 by while population, C = 1.85 billion.
To Find :
The average number of gallons of fruit juice consumed per person in the country in 2006.
Solution :
We know, 1 billion = 1000 million.
C = 1.85 billion = 1850 million.
Now, average umber of gallons of fruit juice consumed per person in the country in 2006 is :
[tex]c =\dfrac{C}{P}\\\\c=\dfrac{1850}{300}\ gallons/person\\\\c=6.17 \ gallons/person[/tex]

What is an equation of the line that passes through the points (-6,-4) and
(-4,0)?
Answer:
y = 2x + 8
Step-by-step explanation:
the equation of a line in slope-intercept form is.
y = mx+b
where m is the slope and b the y-intercept
to calculate m use the gradient formula
m = (y2−y1 ) / (x2−x1)
let (x1,y1)=(-6,-4) and (x2,y2)=(-4,0)
m = (0 - (-4)) / (-4 - (-6) = 2
y = 2x+b←is the partial equation
to find b substitute either of the 2 given points
into the partial equation
using (-6, -4) then
-4 = -12+b⇒b=8
y = 2x + 8←is the equation of line

A paint company claims their paint will be completely dry within 45 minutes after application. Recently, customers have complained drying times are longer than the claimed 45 minutes. A consumer advocate group takes a random sample of 25 paint specimens and records their drying times. The average drying time x is 52. Consider dryng time, for all test specimens, to be normally distributed with ? = 6.
Suppose the claimed drying time is true, that is ? = 45 minutes, what is the probability of observing a sample mean of x = 52 or greater from a sample size of 25? (Round your answer to four decimal places.)
Answer:
The probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026
Step-by-step explanation:
Mean = [tex]\mu = 45[/tex]
Population standard deviation =[tex]\sigma = 6[/tex]
Sample size = n =25
Sample mean = [tex]\bar{x} = 52[/tex]
We are supposed to find the probability of observing a sample mean of x = 52 or greater from a sample size of 25 i.e.[tex]P(x\geq 52)[/tex]
[tex]Z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}\\Z=\frac{52-45}{\frac{6}{\sqrt{25}}}[/tex]
Z=5.83
P(Z<52)=0.9999974
[tex]P(Z\geq 52)=1-P(z<52)=1-0.9999974=0.0000026[/tex]
Hence the probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026
Answer:
the probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026

Ray is buying some ginger roots to brew some fresh ginger ale. The price of the ginger roots is GGG, and Ray has a coupon for 10\%10%10, percent off. The expression 0.99, G represents the price Ray pays for the ginger roots after using the coupon. What does 0.90, 9 represent in this context?
Answer:
0.9 in the context represent the price of the ginger
It is called decreasing factor for the function because it decreases the price of the ginger
Step-by-step explanation:
Original price of fresh ginger ale = G
Coupon = 10% off
The actual price paid = 100% - 10% of G
= 90% of G
= 90/100 × G
= 0.9 × G
= 0.9G

=360
360=164+71+24+x
360=260+x
x=360-260
x=100
Answer:
Step-by-step explanation:
Since angles in quadrilateral (4-sided shape) add up to 360 degrees
therefore,
360 = 164 + 71 + 25 + x
360 = 260 + x
subtract 260 from both sides
360-260 = 260-260 + x
100 = x

The area of the parallelogram is 50 square kilometers. What is the parallelogram's base, b?
Answer:
✓50 km
Step-by-step explanation:
Here, Area of parallelogram = base x height
so, at least two data should be given,
hence, let us consider base = height in this case.
Here it becomes,
Area of parallelogram = base²
50 km² = base²
Now, providing square root on both sides,
we get,
✓50 km = base
