Open-Ended Total consumption of fruit juice in a particular country in 2006 was about 1.76 billion
gallons. The population of that country in 2006 was 500 million. What was the average number of
gallons of fruit juice consumed per person in the country in 2006? Use pencil and paper. Using the
per person amount from this problem, about how many gallons would your class consume?

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
