Answer: 50.84%
Step-by-step explanation:
(89-59) /59 = 0.5084/100 = 50.84%
V=(4/3)(pi)(r^3)
V=(4/3)(pi)(8^3)
V=(4/3)(pi)(512)
V=(2048/3)(pi), or around 2144.660585
I’m not 100% sure kind of a guess but I would x=2/3. Good luck

Answer:
It is proved that if
is even the n is even.
Step-by-step explanation:
Given n is any integer.
To show
is even then n is even.
Proving by contrapositive suppose
is odd. Then we need to show n is odd.
Then, letting k is a ny integer,
Now since (2k+1) is odd therefore n is odd.
Conversly let n is odd, then,

since 2k+1 is odd so
is odd.
This proves, if n is even then
is even.
