There are 81 girls to every 72 boys in total, which can be represented by 81/72, which put into decimal form, is 1.125. If you then take the number of boys in the group, 16, and multiply it by this number (because the problem states that the ratio is constant) you can find the number of girls in the group.
16*1.125=18
So there are 18 girls in a group with 16 boys.
Answer:
40k^2(3k - 2) + 48(3k - 2)
(40k^2 + 48)(3k - 2)
8(5k^2 + 6)(3k -2)
Step-by-step explanation:
Answer:
The answer to your question is width = 8ab³
Step-by-step explanation:
Data
Area = 32a³b⁴ u²
length = 4a²b u
Formula
Area of a rectangle = width x length
Solve for width
width = 
Substitution
width = 
Simplify using rules of exponents, just remember that in a division we subtract the exponents and divide the coefficients normally.
width = 8 a²b³
Im pretty sure it's -18x^11
