Mr. murray wants to create 100 ounces of a mixture that is 62% pecans, 30% almonds, and 8% walnuts. how will the amount of mixture a compare to the amounts of mixtures b and c that mr. murray uses? he will use half as much of mixture a as he will use of mixtures b and c combined.he will use one-quarter as much of mixture a as he will use of mixtures b and c combined.he will use one-fifth as much of mixture a as he will use of mixtures b and c combined.he will use twice as much of mixture a as he will use of mixtures b and c combined.

Maximize the lateral surface area of an inverted cone if v=27. formulas: v=pi*r^2*h/3 surface area=pi * r* sqrt of (r^2+h^2) i found that h=81/pi*r^2, but i don't know where to go after this.
