Hello!
The volume of the square pyramid is approximately
____________________________________________________________
V =
First, we must find the area of the square base.
A = l * w
A = 3.5 * 3.5
A = 12.25 km^2
The area of the base is 12.25 km^2. Now, multiply the base area by the perpendicular height. Then divide by 3.
V = (12.25 * 4.7) / 3
V = 19.1916666667
V ≈ 19.19 km^3
Answer:
the charge is $5 dollars per mile
Step-by-step explanation:
He truck is rented at $40 per day plus they charge per mile of use the truck travel 15 miles in one day and the total charge was 115
LEt x be the charge in dollars per hour
Initial charge is 40 and 15 miles travelled in one day
total charge = 15x + 40
Given : total charge is 115
So the equation becomes
Now we solve for x
Subtract 40 from both sides
Divide both sides by 15
x= 5
so , the charge is $5 dollars per mile
