Answer is <span>C. 80
hope that helps
75% are full with 20 seats empty so </span>20 seats empty = 25%
75% * 20 / 25% = 60
Subtract 20n from both sides of the equation.
n^2+100-20n=0
factor using the perfect square rule.
(n-10)^2=0
set the n-10 equal to 0.
n-10=0
add 10 to both sides of the equation.
n=0
14 plus 40 equals 54 divided by 3 equals 18
The answer is 18
Well if each side is 6cm each then u Have to multiply 6x how many sides to the cube there are. So if there are 6 sides to a cube and you have 6cm each side then you have to multiply 6cm X 6 witch = 36 then multiply 36X6=216. So the final answer is 216.
Hope this helps!
