A...............................
Xb + xr + xc = m
X being the amount of supplies
B are the price of the brushes
R is the price of the rollers
C the price of the paint cans
M is the total price
YOU'RE WELCOME :D
Well, if you bought 10, it would be $2, but due to the decreasage, if you bought 8 it would be $2. The prrcantage decrease should be 20%.
Answer:
Radius of the sphere = ![\sqrt[3]{91.13} \,feet](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B91.13%7D%20%5C%2Cfeet)
Step-by-step explanation:
Volume of a sphere is :
For, Volume = 
As, 
![121.5\times \pi =\dfrac{4}{3}\times \pi \times r^3 \\\\121.5=\dfrac{4}{3}\times r^3\\\\ 121.5\times \dfrac{3}{4} =r^3\\\\r^3=91.13\\\\r=\sqrt[3]{91.13} \,feet](https://tex.z-dn.net/?f=121.5%5Ctimes%20%5Cpi%20%3D%5Cdfrac%7B4%7D%7B3%7D%5Ctimes%20%5Cpi%20%20%5Ctimes%20r%5E3%20%5C%5C%5C%5C121.5%3D%5Cdfrac%7B4%7D%7B3%7D%5Ctimes%20r%5E3%5C%5C%5C%5C%20121.5%5Ctimes%20%5Cdfrac%7B3%7D%7B4%7D%20%3Dr%5E3%5C%5C%5C%5Cr%5E3%3D91.13%5C%5C%5C%5Cr%3D%5Csqrt%5B3%5D%7B91.13%7D%20%5C%2Cfeet)
The radius of the sphere is :
Use the distance formula to find width and length D= sqrt[(<span>x2</span>−<span>x1</span><span>)^2</span>+(<span>y2</span>−<span>y1</span><span>)^<span>2], then use the perimeter formula, P=2width+2length</span></span>
