Step-by-step explanation:
Answer:
V = 4000 cm^3
Step-by-step explanation:
The volume of the sphere is given by
V = 4/3 pi r^3
We are given the radius of 10 and are to use 3 for pi
V = 4/3 (3) * (10)^3
V = 4/3 *3 * 1000
V = 4000 cm^3
Just combine like terms.
16 – 12a – 20 + 6a
16 - 20 -12a + 6a
-4 - 6a
We can factor to further simplify.
2(-2 - 3a)
Multiply both sides by the reciprocal of 1/5
Simplifying
7 + -8n = 1
Solving
7 + -8n = 1
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + -8n = 1 + -7
Combine like terms: 7 + -7 = 0
0 + -8n = 1 + -7
-8n = 1 + -7
Combine like terms: 1 + -7 = -6
-8n = -6
Divide each side by '-8'.
n = 0.75
Simplifying
n = 0.75
