5x5x5=125
12x3=36
36x3=108
108+125=233
233in^3 is the answer
-1/5of 15 =-3 then add 3 2/5th which is 17/2 so -3+17/2 = 11/2=5 1/2
We are given with the function summation of 16*(5) ^(I-1) from 1 to infinity. As we assume in the calculator that infinity is equal to a very large number, the result that can be obtained is undefined. This means the number is very large. This is because the ratio (15) is large too. The series is divergent since the number in the infinite geometric series is ever increasing. Answer is B.
The answer is .75
Think of it this way 1/4 is one quarter as in a quarter of a dollar which equal .25 of a dollar (25 cents) 3 quarters is 75 cents so .75
