Answer:
15 to 27 (which is equal to 5:9)
Step-by-step explanation:
The ratio 15 to 12 indicates that there is a total of 27 people in the classroom (15+12). So, if you want boys to total students, it's 15 to 27.
You can divide each of these by 3 to simplify it and get 5:9.
Answer:
$23.11
Step-by-step explanation:
We can use a proportion to find the meal tax
7 : 100 = x : 21.60
x = (21.60 * 7)/100 = $1,512
Final cost = 21.60 + 1,512 = $23.11

Answer:
Option D is correct.
Step-by-step explanation:
We are given ![\sqrt[5]{x^7}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%5E7%7D)
We know that![\sqrt[5]{x} = x^\frac{1}{5}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%7D%20%3D%20x%5E%5Cfrac%7B1%7D%7B5%7D)
and we are given:
![\sqrt[5]{x^7}\\ We\,\, can\,\, write\,\, as\,\,\\x^\frac{7}{5}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%5E7%7D%5C%5C%20We%5C%2C%5C%2C%20can%5C%2C%5C%2C%20write%5C%2C%5C%2C%20as%5C%2C%5C%2C%5C%5Cx%5E%5Cfrac%7B7%7D%7B5%7D)
So, Option D is correct.
