Answer: 11.375°

Step-by-step explanation:

55 + (4x + 17) + (4x + 17) = 180° Set up equation

4x + 4x + 55 + 17 + 17 = 180° Commutative Property of Addition

8x + 89 = 180° Combine like terms

8x = 91° Subtract 89 from both sides

x = 11.375° Divide both sides by 8

Not entirely sure about this one; you might have to round the answer.

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]

Answer:

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

Step-by-step explanation:

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
