two angles are complementary when the sum of them is equal to 90 degrees
301=3n+1
solve for n, if it is a natural number (1,2,3,4,5...) then it is in the sequence
301=3n+1
minus 1
300=3n
divide 3
100=n
yes it is
it is the 100th term
This is a ratio problem. You only need solve the ratio of the sand.
<u> 48 </u> <u /> = <u> n </u> <u />
1 156
(48)(156) = 1(n) (cross multiplying)<span>
</span>
7,488 pounds
To check: The pool deck is 156 times larger than the original amount of concrete so the amount of sand needs to be 156 times more.
