ANSWER: Solve for volume
V≈79.26m³
An above ground pool is shaped like a cylinder. It is 5.5 feet tall and has a diameter of 20 feet. If the pool is filled to 5 feet, what is the volume of the water? If the pool is filled to the top, what is the volume of the water?
First, we must know the formula for solving the volume of a cylinder, which is [tex]V = \pi r^2 h[/tex]. Since the water is only being filled to 5 feet, we do not care about the 0.5 feet of the height.
Using the formula, we need to plug-in the numbers for the radius (20 divided by 2 is 10) and height. Doing this, the equation should now look like this: [tex]V = 3.14 * 10^2 * 5[/tex]. When solving, the volume of the water is 1570 feet cubed.
Answer:
1570.796 feet cubed
Step-by-step explanation:
First you find the surface area of the base of the cylinder which should look like this:
(10^2)(π)
Next you multiply that by the height (5 feet) because 3d shapes are bases stacked on each other which should look like this:
314.1592654(5)
After that arithmetic you will get 1570.796 or 1570.8 rounded as your answer!

4(x +t) = M
Answer:
x = (M-4t)/4
Step-by-step explanation:
First we expand the brackets:
4(x+t) =M
4x +4t = M
Subtract 4t from both sides:
4x +4t -4t = M -4t
Simplify:
4x = M -4t
Divide both sides by 4 :
4x÷4 = (M-4t)/4 = (M-4t)÷4
x = (M-4t)/4

Consider two events, P and Q. The probability of event P occurring is 16. The probability of event Q occurring is 23. Which statement is true?
The event "P and Q" is a compound event in the probability, and the true statement about the probability is P(P and Q) = 1/9
How to determine the true statement?The probabilities are given as:
P(P) = 1/6
P(Q) = 2/3
The probability of the event P and Q is calculated using:
P(P and Q) = P(P) * P(Q)
This gives
P(P and Q) = 1/6 * 2/3
Evaluate the product
P(P and Q) = 1/9
Hence, the true statement about the probability is P(P and Q) = 1/9

A quadratic equation is in the form of ax²+bx+c. The graph of the equation y = -2x² + 4x -5 will not intersect the x-axis at any point.
What is a quadratic equation?A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
The given equation is a quadratic equaion, therefore, to know if the equation will intersect with the x-axis we need to find the roots of the equation.
Since the value of the discriminant is negative for this equation, the roots of the equation will be imaginary. Plotting the graph, we will observe that the graph will not intersect the x-axis at any point.
Hence, the graph of the equation y = -2x² + 4x -5 will not intersect the x-axis at any point.

Answer:
(- [tex]\frac{1}{5}[/tex] , 0 )
Step-by-step explanation:
to find where the line crosses the x- axis, let y = 0 in the equation and solve for x
5x - 2(0) + 1 = 0
5x - 0 + 1 = 0
5x + 1 = 0 ( subtract 1 from both sides )
5x = - 1 ( divide both sides by 5 )
x = - [tex]\frac{1}{5}[/tex]
the line crosses the x- axis at (- [tex]\frac{1}{5}[/tex], 0 ) or ( - 0.2, 0 )
Answer:
(-1/5, 0).
Step-by-step explanation:
Where the line crosses the axis the value of y = 0.
5x - 2y + 1 = 0
Let y = 0, then:
5x - 2(0) + 1 = 0
5x + 1 = 0
5x = -1
x = -1/5.
So the point is (-1/5, 0).

Mr. Schultz is randomly distributing 15 rulers with centimeter markings and 10 rulers without centimeter markings to his class. What is the probability that the first ruler he hands out will have centimeter markings and the second one does not have the markings?
The probability that the first ruler he hands out will have centimeter markings and the second one does not have the markings is 9/40.
Probability of distributing the rulers
The probability of distributing the rulers is calculated as follows;
Total outcome = 15 rulers with centimeter markings + 10 rulers without centimeter markings
Total outcome = 25
The probability that the first ruler he hands out will have centimeter markings and the second one does not have the markings;
P = (R with M) and (R without M)
P = (15/25) x (9/24)
P = (3/5) x (3/8)
P = 9/40
Thus, the probability that the first ruler he hands out will have centimeter markings and the second one does not have the markings is 9/40.
