Answer:
151200
Step-by-step explanation:
We can start by essentially taking off the E at the end, meaning that we want to find all the combinations of
EVANESCENC. We can do this because the combinations will have an E at the end by default.
To solve this, we have to figure out the amount of letters and the amount of each letter. There are 10 letters, with 3 E's, 2 C's, 2 N's, 1 S, 1 V, and 1 A. Using the formula
, with n representing the amount of letters and each subset of n representing the amount of each letters, our answer is

Answer:
- 27 is 18 multiplied by 3/2
- 18 is 2/3 of 27
Step-by-step explanation:
The ratio of the two numbers is 18/27 = (2·9)/(3·9) = 2/3.
So, if you're starting with 27 and you want to scale it down to 18, you multiply by the scale factor 2/3.
If you're starting with 18 and you want to scale it up to 27, you use the inverse of the above scale factor. That inverse is 3/2.
Answer:
There are 480 boys at the school.
There are 320 girls at the school.
Step-by-step explanation:
The |*| symbols take away the negative value of a number. So |-3| is just “3”. I can explain more if needed :)
