Answer:
15 feets
Step-by-step explanation:
Perimeter of a rectangle = 2(l + w)
l = Length ; w = width
Perimeter, p = 48
Length of all sides
p = 2(l + w)
48 = 2(l + 9)
48 = 2l + 18
48 - 18 = 2l
30 = 2l
l = 30/2
l = 15
Length of the sides = 15 feets
The answer is 75 because 50+60+115=225 divided by 3 is 75
Sixth grade
Because if you divide their total profit by the total amount of hours they worked, you would find that the sixth grade's income per hour is the highest.
Sixth grade: 170÷5=34
Seven grade: 112÷4=28
Eighth grade: 192÷6=32
-23 over 5 ÷ 11 over 5
-23 × 5 over 5 × 5
-115 over 55
Therefore, your answer would be: -2 and 1 over 11
