Answer:

4 hours and 7 hours

Step-by-step explanation:

Marcus = x hours

Donnell = x + 3 hours

Total = 11 hours

  • x + x + 3 = 11
  • 2x + 3 = 11
  • 2x = 8
  • x = 4

So Marcus practiced 4 hours and Donnell practiced  7 hours

The volume of a sphere is 288pi cm^3<br>What is the radius of the sphere?​
Otrada [13]

Answer:

radius = 6 cm

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = \frac{4}{3} πr³ ← r is the radius

Given V = 288π, then

\frac{4}{3} πr³ = 288π

Multiply both sides by 3 to clear the fraction

4πr³ = 864π ( divide both sides by 4π )

r³ = 216 ( take the cube root of both sides )

r = \sqrt[3]{216} = 6

Thus the radius of the sphere is 6 cm

Answer:

x=145

Step-by-step explanation:

There are two ways to solve:

-Vertical angles Theorem states that opposite angles are congruent, so x=145 degrees.

-Sameside angles are supplementary so:

35+x=180

Subtract 35 from both sides:

x=145
