Answer:
2 1/25 or 2.04
Step-by-step explanation:
8 ^ 1/3 + 5 ^ (-2)
Rewriting
(2^3) ^ 1/3 + 1/5 ^2
2 + 1/25
2 1/25
2.04
900 divided by 12 so thats $75 each month
Answer:
$ 9 each bottle
Step-by-step explanation:
1 crate = $45
1 crate = 25 bottles
if we want to earn $180 per crate , we have to add this value to the $45
45 + 180 = 225
if the value of the box to win $180 is $225, we have to divide the new value by 25 (number of bottles) and we will have what we will have to charge each bottle
225/25 = 9
we have to charge $ 9 each bottle to earn $ 180 per crate
An equation to solve for the time when the high school will have exactly 100 students is (1-.06)^x = (250/100).
That simplifies to 94^x = .4.
We can then take the log of both sides to isolate the x variable from the exponent. Here's with natural log.
x*ln(.94)=ln(.4)
x = ln(.4)/ln(.94)
Solving this gives x ~= 14.80. So in about 15 years, the high school will have 100 students.
