Before the new kids the ratio of girls to boys is 15:12 because there are 15 girls and 12 boys now you can simplify by dividing 15 by 3 and 12 by 3 to get 5:4 as your simplified ratio. As far as after the new kids. Since there is 1 new girl you do 15+1 to get 16 and there are 3 new boys so you do 12+3 to get 15 now 16:15 is already in simplest form so your answer is:
Before: 15:12 simplified as 5:4
After 16:15
In order to get the answer to this question you have to remember that if the exponent is positive you need to move to the right, and if the exponent is negative you got to move to the left.
- Positive so move to the right 8 times....
Therefore the answer is "490000000."
Hope this helps!

Answer:
Your answer is B
Step-by-step explanation:
There are 3 kids ages 9-10, so that's the first 3.
There are 10 kids ages 10-11, so that's the second 10.
There are 6 kids ages 11-12, so that's the third 6.
add those kids up and you get 19
I think not because a square has four sides and a triangle has three.
