"9 and 9?" Did you possibly mean {2, 5, 6, 9}?
The least common multiple of a set of numbers is the smallest integer that can be divided evenly by all of the numbers. In this case, when I saw the 9 and 5, I thought, "45!" but 45 is not evenly divisible by 2 or 6.
So, I tried 90. 90 is indeed divisible by {2, 5, 6, 9}, and is thus the LCM.
Look up and review "Least common multiple."

Answer:
80 copies
Step-by-step explanation:
4 minutes= 240 seconds. So I did 240 seconds divided by 3 seconds (one copy is made in that time) then you get 80. I don't know if that explanation make sense but the math checks out.
Answer:
C) 8 and 9
Step-by-step explanation:
We know that 70 is between two perfect squares.
The square numbers 64 and 81 can help us solve this question.
64<70<81
We take square root to get:

We simplify this to get:

Therefore √70 is between 8 and 9.
The correct option is C.
