That would be the number of permutations of 3 from 10.
= 10P3 = 10! / 7! = 10*9*8 = 720
Hello,

Answer:
- 12=0.005×w
- the number is 2400
Step-by-step explanation:
An appropriate representation of the problem can be had by using a variable to represent "what number" and then using the math equivalent symbols for the English words. If "what number" is represented by w, then we want to translate ...
0.5% of w is 12 . . . . English
0.005 × w = 12 . . . . . . . matches choice 1
__
This can be solved by multiplying by 200
200(0.005w) = 200(12)
w = 2400
The number is 2400.
