First you need to figure out how many yards of ribbon you are buying. To do that divide 11 by 3. That equals 3 2/3 yards. You divided it by 3 because there are 3 feet in 1 yard.

next you need to change 3 2/3 yards into an improper fraction. Multiply the whole number 3 by the denominator that ='s 9 and it to the numerator that ='s 11 so now you have the improper fraction 11/3 that represents the number of yards of ribbon you are buying. Then multiply $1.32 * 11/3 = $14.52/3 reduced = $4.84

Paid $4.84 for the ribbon

There are three feet of ribbon in a yard. So 11 feet is 3.66 yards. Then multiply the cost of a yard by the number of yards (1.32 times 3.66) and you get the answer: 4.83 dollars

The volume of a right triangular prism is 72 cubic feet. The height of the prism is 9 feet. The triangular base is an isosceles

Mariulka [41]

Answer:

Step-by-step explanation:

volume = area of base * height = area of base * 9 = 72

-> area of base = 72/9 = 8

let a,b,c be the length of sides of isosceles right triangle base

we have a = b and a*b/2 = 8 ft2

-> a*a/2 = 8ft2

-> a*a = 16

-> a=4ft=b
