RQ/circumference = 65/360
RQ = 65*circumference/360
= 65*2*pi*6.48/360
= 117pi/50
= 7.4 inches
Step-by-step explanation:

There is no common factor
Step-by-step explanation:
Answer:
-14x + 21
Step-by-step explanation:
Use the distributive property to solve. Multiply -7 by each number in parentheses. -7 times 2x is -14 x and -7 time -3 is 21 (a negative times a negative is a positive). You should get -14x + 21 as an answer. You are no longer able to simplify any farther from there.
Answer:
C
Step-by-step explanation:
Since the triangle is right use the sine ration to find y
sin30° =
= 
Multiply both sides by 8
y = 8 × sin30° = 8 ×
= 4 → C
