Help please! Sorry about all the questions, I'm stuck.

Let's use the process of elimination:

We know the bottom two are incorrect, because numbers that are divisible by 9  ARE divisible by 3.

Take 18 for an example. 18 is divisible by 3 (3 * 6 = 18), and 9 (9*2 = 18).

Some of the numbers that are divisible by 9 are also divisible by 3 isn't the best statement, because we know that all multiples of 9 are divisible by 3.

Now we have 2 of them.

I think it's the second one, because the first one doesn't explain the details between the relationship of 9 and 3 (as well as the second one).,

So I think it's the second from the top.

(A number that is divisible by 9 is also divisible by 3, because all factors of 9, are factors of 3.)

A

Step-by-step explanation:

any number divisible by 9 is also divisible by 3,because 3 is a factor of 9.

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
