Circumference of a circle:
C = 2 r π;
Length of an arc:
L = r π α / 180°
L = r π · 30° / 180° = r π /6
r π /6 : 2 r π = 1/6 : 2 = 1/12
Answer: A ) 1/12
Answer: B
Step-by-step explanation:
A factorial is multiplying the integer and all of the integers below it together.
5x + 9x +15x = 130
29x = 130
x =

8/10 can be simplified to 4/5 by dividing the top and bottom by 2. That is the simplest form because you cannot divide it any further.
