50 * 2 = 100
50 + 50 = 100
Answer:
The volume = 523.3 ft.³
Step-by-step explanation:
∵ Surface area of the sphere = 4πr²
∴ 4πr² = 100π
∴ 4r² = 100 ⇒ r² = 100/4 = 25
∴ r = √25 = 5 ft.
∵ Its volume = 4/3 πr³
∴ Its volume = (4/3) × π × 5³ = 523.3 ft.³
Answer:
3h + 3
Step-by-step explanation:
Distribute 3 to all terms within the parenthesis, and multiply:
3(1 + h) =
3(1) = 3
3(h) = 3h
3h + 3 is your answer.

Rewrite your function as a equation:
y=0.15x -75
Use the slope-intercept form to find the slope and y-intercept:
y=mx+b
Find the values of m and b using the form y=mx+b
m=0.15
b= -75
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 0.15
Y-Intercept: -75
