Answer:
So, the relation between variables are
![y=\frac{x^4}{7}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7Bx%5E4%7D%7B7%7D)
Step-by-step explanation:
We are given
![\frac{x^4}{y}=7](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E4%7D%7By%7D%3D7)
Since, we have to find relation between variables
so, we can solve for y
![\frac{x^4}{y}=7](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E4%7D%7By%7D%3D7)
Firstly, we will multiply both sides by y
![\frac{x^4}{y}\times y=7\times y](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E4%7D%7By%7D%5Ctimes%20y%3D7%5Ctimes%20y)
we can simplify it
![x^4=7\times y](https://tex.z-dn.net/?f=x%5E4%3D7%5Ctimes%20y)
we can isolate y
so, we can divide both sides by 7
so, we get
![y=\frac{x^4}{7}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7Bx%5E4%7D%7B7%7D)
The square root of 225 is 15. I hope that helped!
The equivalent ratio of 9:25 is 36:100.
Ratio expresses the degree of proportionality between two or more numbers. It expresses the number of times one number is contained in another number.
In order to make the ratios equal, the relationship that exists between 9 and 36 has to be determined. 36 is a multiple of 9. It is 9 multiplied by 4. So, in order to make the ratios equal, multiply, 25 by 4.
25 x 4 = 100
