Answer:
D. 125%
Step-by-step explanation:
First day = 80 responses
Second day = 180 responses
Increase in responses = 180 - 80
= 100 responses
what percent is the increase 100 of the original number of responses 80
= Increase in responses / original number of responses × 100
= 100/80 × 100
= 1.25 × 100
= 125%
The percent increase 100 of the original number of responses 80 = 125%
So by the look of it angle D is 90, and because the hypotenuse on both triangles are the same that means that both triangles are the same, so Y would be 2. Also once again a triangles angles add up to 180 and we know that one angle is 51 and the other is 90 then you need to add them together getting 141 and subtract that from 180, getting an answer of 39, if my calculations are correct then X=39 and y=2
Answer:
I can help you in comments so I can explain this to you
The total expenses of Marco's account are $174. The ending balance is $81. So, the starting balance will be $255.
