A cylindrical fish tank at the zoo has a capacity of 7252 cubic feet
What is the height of the tank if it’s radius is 16 feet?
Answers
Replacing with values given:
7252 = 3.14 ( 16 )² h
Solving for h (height)
7252 / 3.14(16)² =h
7252 /3.14 (256) =h
7252 / 803.84 = h
9.02 =h
The height of the tank is 9.02 feet
Answer : 9.02 feet
The height of the tank if it’s radius is 16 feet is,
⇒ Height = 9.02 feet
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A cylindrical fish tank at the zoo has a capacity of 7252 cubic feet.
Now, We know that;
Volume of a cylinder = π × radius² x height
Here, Radius is 16 feet.
Hence, We get;
Volume of a cylinder = π × radius² x height
7252 = 3.14 × 16² × h
⇒ 7252 = 803.84 h
⇒ h = 7252 / 803.84
⇒ h = 9.02 feet
Thus, The height of the tank if it’s radius is 16 feet is,
⇒ Height = 9.02 feet

Given:
A box-and-whisker plot of data set.
To find:
The percentage of the data values that are greater than 80.
Solution:
From the given box-and-whisker plot, it is clear that:
Minimum value = 8
First quartile = 60
Median = 68
Third quartile = 80
Maximum value = 92
We know that the 25% the data value are greater than or equal to third quartile because the third quartile divides the data in 75% to 25% and 80 is the third quartile.
Therefore, about 25% of the data values that are greater than 80.

Eighteen students decide they don't want to be
rescued and want to continue to live in the
jungle. If this represents 40% of the students,
how many students want to be rescued?
Type your answer into the box to continue.
Answers
Answer: 45
Step-by-step explanation:
18 = 40% N
18 = 0.4 N
Divide both sides by 0.4
N = 45
There are 45 students want to be rescued.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Eighteen students decide they don't want to be rescued and want to continue to live in the jungle.
And, This represents 40% of the students.
Now,
Let the number of students want to be rescued = x
So, We can formulate;
⇒ 40% of x = 18
Solve for x as;
⇒ 40/100 × x = 18
⇒ 40x = 1,800
⇒ x = 1800/40
⇒ x = 45
Thus, The number of students want to be rescued = 45

Answer:
y = 5x - 8
Step-by-step explanation:
The linear equation in slope intercept form :
y = mx + c
m = slope ; c = intercept
m = Rise / Run = (y2 - y1) / (x2 - x 1)
Rise = (y2 - y1) = (12 - (-8)) = (12 + 8) = 20
Run = (x2 - x1) = (4 - 0) = 4
Slope, m = Rise / Run = 20 /4 = 5
Hence,
y = 5x + c
For the points ; y = 12 ; x = 4 ; we could obtain c
12 = 5(4) + c
12 = 20 + c
12 - 20 = c
-8 = c
The equation becomes :
y = 5x - 8
