Answer:
112in²
Step-by-step explanation:
Formulas: V = 
, V = lwh
Sub: v = 
Solve: 32
Sub: v = 4 x 4 x 5
Solve: 80
V = 80 + 32
V = 112
<u>The total volume of the figure is 112in²</u>
If you're trying to get x your answer would be -21.
Total amount of money paid
=11 x 15
=$165
total amount of money sold
=25 x 15
=$375
difference
= 375 - 165
=$210
Let the total number of cans be x and the total number of tennis balls be y,
Since increasing the total number of cans causes the total number of tennis balls to increase too, x and y is direct in proportion.
Let the constant be k,
y = kx
45 = k9
k = 45/9
= 5
The constant of the proportionality for this situation is 5.
