Answer:
A
Step-by-step explanation:
One complete turn is 1 perimeter (aka circumference).
We have to find the length it turned, hence, its circumference.
The formula for circumference (C) of a circle is:

Where r is the radius
The radius is HALF of diameter. Given diameter is 250, the radius is:
r = 250/2 = 125 feet
Now, substituting in formula we have:

So, it turned 785.4 feet with 1 rotation.
The correct answer is A
Answer:
C
Step-by-step explanation:
The inequality is
40m + 300 > 1,000
subtract 300 from both sides 40m > 700
divide both sides by 40 m > 700/40
(don't reverse the sign. 40 is (+)) m > 70/4
m > 17.5
The answer is C. Madison will not reach her goal in 17 months, but she will be there by the end of the 18th month.
