To find the Y-intercept it would be the first number in the column of Y that goes with 0 which is 4. To find the slope you would have to find the difference between each number which would be -1. And the root would also be 4 since it’s the X - intercept

The weight of water is 62 and one half lb per cubic foot. How many cubic feet would be occupied by 180 lb of water?

inessss [21]

<u>Answer:</u>

$2\frac{22}{25}$ cubic feet

<u>Step-by-step explanation:</u>

We are given that the weight of water is 62 and one half lb per cubic foot and we are to find the number of cubic feet that would be occupied by 180 lb of water.

For that, we will divide total amount of water by per unit weight of water:

Cubic feet occupied by 180 lb of water = $\frac{180}{62.5} =$ = 2.88 cubic feet or $2\frac{22}{25}$ cubic feet
