If the slice is made parallel to the base, then if the base is a rectangle, the cross-section would be A. rectangle
Let 'x' represent the amount of 50% mixture used, then '20-x' represents the amount of 10% mixture used
0.25(20) = 0.50x + 0.10(20-x)
solving for 'x' we have x=7.5
20-7.5 = 12.5
7.5 pounds of 50% mixture should be combined with 12.5 pounds of 10% mixture
Answer:
f⁻1(x)=(x/7)+(5/7)
Step-by-step explanation:
To find the inverse, interchange the variables and solve for y.
Answer:
a = 8.2 cm, b = 37.5 cm
Step-by-step explanation:
80/500 = (a/20.5)²
a²/420.25 = 80/500
a² = (80 * 420.25)/500 = 67.24
a = 8.2 cm
80/500 = (15/b)²
225/b²=80/500
b² = (225 * 500)/80 = 1406.25
b = 37.5 cm
