Answer:
9(x-12)=24
Step-by-step explanation:
18.66 quarts of paint is needed to paint the swimming pool with two coats of paint
<em><u>Solution:</u></em>
Given that,
<em><u>A swimming pool is in the shape of a rectangular prism</u></em>
Length = 20 feet
Width = 10 feet
Height = 5 feet
<em><u>Find the surface area of prism</u></em>

Where, "l" is the length and "w" is the width and "h" is the height

Thus surface area area of prism is 700 square feet
Given that,
One quart of water-resistant paint covers 75 square feet
Therefore,
1 quart paint = 75 square feet
x quart = 700 square feet
This forms a proportion

Thus 9.33 quarts of paint is needed to cover 700 square feet
How many quarts should you buy to paint the swimming pool with two coats of paint
For two coats of paint we need = 9.33 + 9.33 = 18.66 quarts of paint
Answer:
Second table.
Step-by-step explanation:
A function has an additive rate of change if there is a constant difference between any two consecutive input and output values.
The additive rate of change is determined using the slope formula,

From the first table we can observe a constant difference of -6 among the y-values and a constant difference of 2 among the x-values.

For the second table there is a constant difference of 3 among the y-values and a constant difference of 1 among the x-values.
The additive rate of change of this table is

Therefore the second table has an additive rate of change of 3.
6 - 3 = 3
-2 - (-9) = 7
(3 , 7)
Answer:
3.14
Step-by-step explanation:
Area of a corcle is sexpressed as';
A = πr²
π = A/r²
π = 78.54/5²
π = 78.54/25
π = 3.1416
When the area is divided by radius the required constant is 3.14
