ANSWER
307½ gallons of water
EXPLANATION
The volume of the rectangular swimming pool is
where l=25ft and w=20½ ft.
when it is filled to a depth of 4½ ft ,then the height is , h=4½ ft.
We substitute these values into the formula to get:
If one cubic foot of water is 7½ gallons, then 2306.25 cubic feet will be
We need 307.5 gallons of water to fill the pool.
Answer:
y = -1x + 2
Step-by-step explanation:
We need to find y = mx + b
Use the following equation
Plug in the values
=
We have found the slope(m) which is -1
We have to find y-int b
Plug in any given x,y into the slope formula
-1 = -1(3) + b
-1 = -3 + b
2 = b
At last the formula is
y = -1x + 2
