Answer:
91.3 in³
Step-by-step explanation:
The volume of a pyramid can be found using the formula ...
V = (1/3)Bh
where B represents the area of the base, and h represents the height.
Since the base is square, its area will be the square of the side length, so the volume is ...
V = (1/3)·(7.4 in)²·(5 in) ≈ 91.3 in³
Write equations for both companies:
Company A = 80 + 0.30x
Company B = 20 + 0.50x
X = number of miles.
Set the equations to equal and solve for x:
80 + 0.30x = 20 + 0.50x
Subtract 0.30x from both sides:
80 = 20 + 0.20x
Subtract 20 from both sides:
60 = 0.20x
Divide both sides by 0.20:
x = 60 / 0.20
x = 300
The answer is 300 miles.
