Hey there! :)
Answer:
arc AB = 2.5π in (in terms of pi) or ≈7.85 in. (pi = 3.14)
Step-by-step explanation:
Begin by finding the circumference of the circle. Use the formula:
C = 2rπ
C = 2(9)π
C = 18π.
Since ∠AQB equals 50°, set up a ratio to find the length of arc AB:

Cross multiply:
50 · 18π = 360x
900π = 360x
Divide both sides by 360:
x = 2.5π in, or ≈7.85 in.
Answer:
5:15
Step-by-step explanation:
5:30 - 15
Answer:
x=-21/19
Step-by-step explanation:
Given -> 18+8x=x-3(1+4x)
Distributive Property -> 18+8x=x-3-12x
Combine like terms on right side -> 18+8x=-11x-3
Subtract 8x from both sides -> 18=-19x-3
Add 3 to both sides -> 21=-19x
Divide both sides by -19 -> x=-21/19
Answer:
