Answer:
E. 400
Step-by-step explanation:
So this is how we set this up, and how we solve

Hope this helps!
So you are solving for circumference of a quarter circle: 
r= 28

20% increase
the percent increase =
× 100%
increase = $12 - $10 = 2$
increase =
× 100% = 20%
Answer:
2/15
Step-by-step explanation:
The answer choices to this question do not make sense since probability is a measure that is always <= 1.0
Based on the number of times a particular colored tile is drawn we can assume that at the minimum there are 6 green, 20 red, 7 blue, 8 purple and 4 black tiles
Total number of tiles = 6 + 20 + 7 + 8 + 4 = 45
Probability of drawing a green tile = 6/45 = 2/15
Answer: 15/5 = 3
Step-by-step explanation:
Let's solve your equation step-by-step.
x/5 = 3
Step 1: Multiply both sides by 5.
x/5 = 3
(x/5) times (5) = (3) times (5)
x = 15
Answer:
x = 15

Answer:
a = 64°
b = 138.7°
Step-by-step explanation:
First, Let's find the measure a,
- 180° = 116° + a
- 180 - 116 = a
- a = 64°
______
Now,
- 90° + a + 82° + x + x + x = 360°
- 90+ 64 + 82 + 3x = 360°
- 236 + 3x = 360
- 3x = 124/ 3
- x = 41.3°
______
Now that we found out what x equals, let's find 'b'-
- b + x = 180°
- b + 41.3 = 180
- b = 180 - 41.3
- b = 138.7°
