Answer:
8 in
Step-by-step explanation:
RA = 4 in, RB = 2 in
oil height in A = hA = 2 in
Find oil height in B = hB
volume of oil in A = VA = π*RA² * hA
equal amount means volume of oil in B VB = VA
But VB = π*RB² * hB
so π*RA² * hA = π*RB² * hB
then
hB = hA *(RA/RB)² = 2 * (4/2)² = 8 in
Answer:
The solution is:
Step-by-step explanation:
Given the expression
![0.5^{10}\div 0.5^7](https://tex.z-dn.net/?f=0.5%5E%7B10%7D%5Cdiv%200.5%5E7)
Solving
![\frac{0.5^{10}}{0.5^7}](https://tex.z-dn.net/?f=%5Cfrac%7B0.5%5E%7B10%7D%7D%7B0.5%5E7%7D)
![\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}](https://tex.z-dn.net/?f=%5Cmathrm%7BApply%5C%3Aexponent%5C%3Arule%7D%3A%5Cquad%20%5Cfrac%7Bx%5Ea%7D%7Bx%5Eb%7D%3Dx%5E%7Ba-b%7D)
so
![\frac{0.5^{10}}{0.5^7}=0.5^{10-7}](https://tex.z-dn.net/?f=%5Cfrac%7B0.5%5E%7B10%7D%7D%7B0.5%5E7%7D%3D0.5%5E%7B10-7%7D)
![\mathrm{Subtract\:the\:numbers:}\:10-7=3](https://tex.z-dn.net/?f=%5Cmathrm%7BSubtract%5C%3Athe%5C%3Anumbers%3A%7D%5C%3A10-7%3D3)
![=0.5^3](https://tex.z-dn.net/?f=%3D0.5%5E3)
∵ ![0.5^3=0.125](https://tex.z-dn.net/?f=0.5%5E3%3D0.125)
Therefore, the solution is:
![\frac{0.5^{10}}{0.5^7}=0.125](https://tex.z-dn.net/?f=%5Cfrac%7B0.5%5E%7B10%7D%7D%7B0.5%5E7%7D%3D0.125)
