How many numbers between 10 and 99 are divisible by 5.

17 because 100 divided by 5 is 20 but you take away 3 because 5, 10, and 100 won't be accepted.

Exponential function

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
