In the past 20 years scientist have seen the sea level rise in a proximately 30.13 inches per year at this rate continues which best represents the change in sea level over the next 27 months

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
