Step-by-step explanation:
5.55% = 1/18
<span>so, cut the cake into 18 equal squares. </span>
<span>The cake is twice as long as it is wide, so that means cut half the cake (6 3/4 x 6 3/4) into 9 pieces, each with a side of 1/3 * 6 3/4 = 2 1/4 inches.</span>
Answer:
He washed 10 cars.
Step-by-step explanation:
To make this easier covert 1/2hours into 1/4 hours. 2 1/2 = 4/2+1/2 = 5/2. Now take 5/2 and make it 1/4th's, 5/2 = 10/4. It takes 1/4 hours to wash one car so, 10/4 divided by 1/4. Don't divide fractions so, 10/4 x 4/1, we switch the second number around to get 40/4. Now we can simplify, 40/4 = 10.
We must calculate the lateral area which is given by:
A = (1/2) * pb * Ap
Where,
pb: perimeter of the base
Ap: Apotema
Calculating the apothem we have:
Ap = root ((646/2) ^ 2 + (350) ^ 2)
Ap = 476.27 feet
Calculating the perimeter of the base we have:
pb = 4 * (646)
pb = 2584 feet
Substituting values:
A = (1/2) * pb * Ap
A = (1/2) * (2584) * (476.27)
A = 615340.84 m ^ 2
Answer:
The minimum amount of glass used for the exterior is:
A = 615340.84 m ^ 2
