Build a sugar-cube pyramid as follows: First make a 5 × 5 × 1 bottom layer. Then center a 4 × 4 × 1 layer on the first layer, center a 3 × 3 × 1 layer on the second layer, and center a 2 × 2 × 1 layer on the third layer. The fifth layer is a single 1 × 1 × 1 cube. Express the volume of this pyramid as a percentage of the volume of a 5 × 5 × 5 cube.

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
