Answer:
acute
Step-by-step explanation:
There are 60 minutes in 1 hour
and 186 divided by 60 = 3 remainder 6
which means you have 3 hours and 6 minutes
that will get you the mixed fraction of
3 6/60 which can be simplified to
3 1/10
If each years cumulate an increase of 1100 dollars, then the cost after 22 years will be the base cost (27000) plus 22 increases (22*1100), for a total of
This relates to arithmetic series as follows: a series is arithmetic if, given a starting element 
, every next element is given by adding a fixed number, called common difference, 
. So, the first terms are
So, you can see that the element 
is obtained by adding n times the common ratio to the starting element.
Since the element 
represents the cost after n years, we are interested in the element
As we had already calculated.
