Answer:
C. 109x
Step-by-step explanation:
We know that there are 109 students in the fourth grade, who each have x cupcakes. In order to find the total amount of cupcakes, we could add all of the cupcakes together to get:
x + x + x + x + .... x
109 times because there are 109 students.
This can be simplified to become 109x.

Answer: Radius = 6 inches</h3>
===========================================================
Explanation:
Let r be the radius we want to find
The area of the full circle is A = pi*r^2
The unshaded portion is 60 degrees, so the unshaded portion must be 360-60 = 300 degrees.
The full area was pi*r^2, but we only want 300/360 of that full area.
So,
s = shaded area
s = (300/360)*(full circle area)
s = (300/360)*(pi*r^2)
s = 30pi
(300/360)*(pi*r^2) = 30pi
(300/360)*r^2 = 30
(5/6)*r^2 = 30
5r^2 = 30*6
5r^2 = 180
r^2 = 36
r = sqrt(36)
r = 6
The radius is 6 inches.
To divide fractions, multiply the first number by the reciprocal of the second.
3/4* 16/3= 48/12
48/12= 4
Final answer: 4
