What is the sum of the first five terms of a geometric series with a1 = 10 and r = 1/5?

12.496

Step-by-step explanation:

The formula to find the sum of geometric progression is given by :-

Given : The first term :

Common ratio =

Then , the sum of first five terms of a geometric series is given by :-

Hence, the sum of the first five terms of given geometric series =12.496

4 + 5 7/9= 9 7/9

step-by-step explanation:

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
