Answer: there are 200 girls in the school.
Step-by-step explanation:
In a school, there is a ratio of 4 boys to 5 girls. The total ratio would be the sum of the proportion of boys and the proportion of girls. Therefore,
Total ratio = 4 + 5 = 9
If there are a total of 450 students, it means that the number of girls in the school would be
Proportion of girls/ total ratio × total number of students. Therefore,
The number of girls is
5/9 × 450 = 200
Answer:
A. x²/y³
Step-by-step explanation:
Given the following data;
Length = x³y⁴
Width =
Ratio = length/width
Simplifying the equation by applying the law of indices (division), we have;
Hence, rearranging the above values;
![Ratio = \frac{x^{2}}{y^{3}}](https://tex.z-dn.net/?f=%20Ratio%20%3D%20%5Cfrac%7Bx%5E%7B2%7D%7D%7By%5E%7B3%7D%7D)
<em>Therefore, the expression that represents the ratio of the length of the rectangle to the width of the rectangle is A. x²/y³. </em>
