An electrician has a piece of wire that is 18 feet long. He cuts off 14% of the wire. Then he cuts the remaining pieces of wire into 3 equal pieces. What is the length of each piece.

the 3 pieces are 5.16ft each and the 14% that he cut off is 2.52 ft

Step-by-step explanation:

the 14 % that he cut off is 2.52ft

he has 15.48ft left

15.48/3=5.16

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
