Answer:
no there not
Step-by-step explanation:
Answer:
the polygon on the right side is doubled the size of the one on the left, therefore x=11
In order to do this we need to make them both fractions, or both decimals. It's much easier to make them both decimals, as you can get

into decimal form by simply dividing 1 by 5.

If 1/5 = .20, then 1/5 is greater than .15!
Class A: 3 out of 30 = 3 / 30 = 0.1 = 10%
Class B: 28 out of 40 = 28 /40 = 0.7 = 70%
Class C: 11 out of 28 = 11 / 28 = 0.39 = 39%
Class D: 14 out of 50 = 14 / 50 = 0.28 = 28%
The answer is Class D
