The second base would be 17 feet.
To find the area of a trapezoid it is (base1 + base2) height

A. 4 cups pineapple juice+8 cups orange juice+12 cups seltzer=24 cups total
108/24=4.5, so you need 4.5*(recipe)=
18 cups pineapple juice, 36 cups orange juice, and 54 cups seltzer
B. each recipe makes 18 servings, so 4.5*(recipe) =4.5*18= 81 servings
C. 8 cups orange juice/12 cups seltzer=2 cups orange juice/3 cups seltzer=2/3 cups orange juice/1 cup seltzer
We have the following variable:
x = The amount of orange juice
We have the following equation:
x + (× + 100) + 1/2 × = 1850
We clear x:
(5/2) x + 100 = 1850
(5/2) x = 1850 - 100
(5/2) x = 1750
x = 1750 / ((5/2))
x = 700 ml
pineapple juice = × + 100 = 700 + 100 = 800 mL
strawberry juice = 1/2 × = (1/2) 700 = 350 mL
The difference is:
800 - 350 = 450 mL
Answer:
The difference in the amounts of pineapple juice and strawberry juice martin combined was:
450 mL
Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
x(x +7) = 170
In standard form, the quadratic is ...
x² +7x -170 = 0
You would do 300• 31/100 to get 90. I’m pretty sure that’s right
