zepelin [54]
Reading          - 44
Sports             - 55
Video games - 55
Music              - 66
--------------------------
                    =  220

Reading = (44/220) x 100 = 20%
Sports = (55/220) x 100 = 25%
Video games -> same as sports
Music = (66/220) x 100 = 30%

20 + 25 + 25 + 30 = 100%

hope this helps :)

Carroll’s is putting a border around the edge of a rectangular bulletin board. One side of the bulletin board measures 2 feet an
olga_2 [115]
Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

First let's establish that the problem requires the border to be as long as the total perimeter of the rectangular bulletin board.

Therefore:

Total length of border = Perimeter of rectangular bulletin board

As a rectangle has a total of four sides with two equivalent longer sides and two equivalent shorter sides, we must multiply the value of each of the two sides by two.

Total length of border = 2 ( 2 ) + 2 ( 4 )

Total length of border = 4 + 8

Total length of border = 12 feet

12 > 10

ANSWER:

Therefore, 10 feet of border isn't enough.
