Which one of these is a rational number A. square root of 9/2
B. square root of 13/16
C. square root of 34
D. square root of 49

D. square root of 49

Step-by-step explanation: D. square root of 49=7

A rational number is either a whole number, or one that has repeating numbers/pattern behind the decimal, For example: 4.13333333333 is rational, because the numbers repeat, it goes on forever with a sequence. If it was irrational then it wouldn't repeat in a (pattern), after the decimal, For example: 4.920581765, it will just go on with random numbers all over the place.

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)
