Formula for the perimeter of a quarter circle: C = ((pi x 2r) / 4) + 2r
C = ((3.14 x 18) / 4) + 18
C = (56.52 / 4) + 18
C = 14.13 + 18
C = 32.13 miles
Hope this helps! :)
The answer is nine. You can write 27 as 27/1. From there, just multiply the fractions.
27/1 x 1/3 = 9
14 Feeders is the correct answer
Answer: 
Step-by-step explanation:
There is a double root at x=5 and a single root at x=-2, so we know f(x) is of the form 
for some constant a.
To find a, we can substitute the coordinates of the y-intercept, (0, -50).
So,
2/3 is <span>the probability that a marble drawn at random is not red.</span>
