Which expression is equal to 9/√45 ?

a. 3√3 / 5

b. 3√5 / 5

c. √5

d. 3√3

B)

Step-by-step explanation:

Because sqrt(45)=sqrt(9*5)=sqrt(9)*sqrt(5)=3*sqrt(5) and you have 9/(3*sqrt(5)). But you need to simplify this further because 9/3 gives you 3, so you have 3/sqrt(5). Since most answer choices won't have sqrt(5) for the denominator, you need to multiply sqrt(5) by the numerator and the denominator in order to get rid of the radicals. Therefore, the answer is B).

q: 92 degrees

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)
