Answer:
10/9
Step-by-step explanation:
This equation is in slope-intercept form, this is referring to the y-intercept. Slope-intercept is y=mx+b, where m is the slope and b is the y-intercept. Therefore, 10/9 is the intercept while -8 is the slope.
Answer:
6.6a+6b-7.1
Step-by-step explanation:

radius = 3 feet
rearrange the formula making r the subject
πr³ = V ( multiply both sides by 3 to eliminate fraction )
4πr³ = 3V ( divide both sides by 4π )
r³ =
= ( 3 × 36π ) / 4π = 3 × 9 = 27
take the cube root of both sides
r =
= 3
