The ceiling of Katie’s living room is a square that is 25 ft long on each side. To decorate for a party, she plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner. (just 2 diagonals) Katie can buy rolls that each contain 30 ft of crepe paper. What is the minimum number of rolls she should buy? (assume the crepe paper is hung flush with the wall and ceiling)

25^2 + 25^2 = c^2 625 + 625 = c^2 c^2 = 1250 c = 35.4

25 + 25 + 25 + 25 + 35.4 + 35.4 = 170.8 (round up to 180) 180 / 30 = 6 rolls

The minimum number of rolls she should buy is 6 rolls

Step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
