Answer:
They are 5 I think
Step-by-step explanation:
It should be correct
Answer:
A. 0.2, 0.25, 0.2
B. the scores are a quarter of the whole
So,
0.2(n - 6) = 2.8
Distribute.
0.2n - 1.2 = 2.8
Add 1.2 to both sides.
0.2n = 4
Divide both sides by .2.
n = 20
Check.
0.2(20 - 6) = 2.8
Simplify inside parentheses.
0.2(14) = 2.8
Multiply.
2.8 = 2.8 This checks.
S = {2.8}
The equation for volume of a sphere is pi(r)^3 This mean that the equation would be pi(11)^3 which equals 1331pi
