The area would be 19.625- inches
Answer:
Step-by-step explanation:
Let the base = x inches
So, h = 2x - 1
Area of triangle = 60 square inches
(1/2) * base *height = 60
(1/2) * x * (2x-1) = 60
x *(2x-1) = 60*2
2x² - x = 120
2x² - x - 120 = 0
2x² - 16x + 15x - 15*8 = 0
2x ( x - 8) + 15 (x -8) = 0
(x-8) (2x + 15 ) = 0
x- 8 = 0 {ignore 2x +1 as it will give negative value}
x = 8
Base = 8 inches
Height = 2*8 - 1 16 - 1 = 15 inches
Answer:

Answer:
5/2cups
Step-by-step explanation:
If a recipe serves 6 and calls for 3/4cups, arecipe that serves 20, will call for (20×3/4)/6 cups. Mathematically;
6recipe = 3/4cups
20recipe = x
Cross multiplying we have;
6x = 20×3/4
6x = 15
x = 15/6
x = 5/2
This means a recipe that serves 20 will call for 5/2cups
