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
2.1 x 4/0.5
2.1 x 4 = 8.4
8.4/0.5 =
16.8
9/12 in simplest form would be 3/4 because you divide bothe 9 and 12 dived by three because what you do to the denominator you do to the nominator so after you divide 9/12 by 3 you would have 3/4 which 3/4 is 9/12 in simplest form
Make it 8/1 and multiply the top number and the bottom number then fone a common factor and divide by that number
It is substitution. Because you are substituting 3=y into x+5=3
