For unit price we can calculate how many cents does an ounce cost, and for doing that we need to divide the amount of total cost in cents by the total ounces:
50 cents/3 ounces = 16.67 cents/ounce
this means that each ounce of nuts costs <span>16.67 cents, that would be the unit price (price in cents per ounce of nuts)</span>
2x-2/8-3x/5 =55/4 distributive property of multiplication over subtraction
(10x-3x)/5-1/4=55/4 combining like terms
7x/5-1/4+1/4=55/4+1/4 addition propriety of equality
7x/5=56/4 add fractions
X=5•56/7•4=280/28=10
The formula for a cone is
![v = \pi \times {r}^{2} \times ( \frac{h}{3} )](https://tex.z-dn.net/?f=v%20%3D%20%5Cpi%20%5Ctimes%20%20%7Br%7D%5E%7B2%7D%20%20%5Ctimes%20%28%20%5Cfrac%7Bh%7D%7B3%7D%20%29)
insert 20 for your height and rearrange the formula to find the radius. Leave a comment if you need more help.
