Answer:3:1
Step-by-step explanation:
Given
There are 27 solid spheres of radius x cm
The volume of a sphere is ![\frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
The volume of 27 old spheres is the same as the volume of a new sphere
The volume of the old spheres is
![V_o=\dfrac{4}{3}\pi x^3](https://tex.z-dn.net/?f=V_o%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%20x%5E3)
The volume of a new sphere is
![V_n=\dfrac{4}{3}\pi y^3](https://tex.z-dn.net/?f=V_n%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%20y%5E3)
Now,![V_o=V_n](https://tex.z-dn.net/?f=V_o%3DV_n)
![\Rightarrow 27\times \dfrac{4}{3}\pi x^3=\dfrac{4}{3}\pi y^3\\\\\Rightarrow (\dfrac{x}{y})^3=27\\\\\Rightarrow \dfrac{x}{y}=3](https://tex.z-dn.net/?f=%5CRightarrow%2027%5Ctimes%20%5Cdfrac%7B4%7D%7B3%7D%5Cpi%20x%5E3%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%20y%5E3%5C%5C%5C%5C%5CRightarrow%20%28%5Cdfrac%7Bx%7D%7By%7D%29%5E3%3D27%5C%5C%5C%5C%5CRightarrow%20%5Cdfrac%7Bx%7D%7By%7D%3D3)
Answer:
x = 4
Step-by-step explanation:
We are to solve for;
-x = -4
A number (n) multiplied by x gives -4. What is the number?
n × x = -4
n is definitely equal to -1
So to get the value of x; we divide -4 by -1 to get 4
Therefore x = 4
