Five pounds of candy that is 20% chocolate is combined with a candy that is 40% chocolate. how many pounds of the candy that is 40% chocolate should be used to get a candy that is 25% chocolate?

5/3 pounds

Step-by-step explanation:

Five pounds of candy that is 20% chocolate is combined with a candy that is 40% chocolate

Let x be the pounds of candy that is added with 40% of chocolate

5 pounds that is 20%. 20% = 0.2

x pounds that is 40%. 40% = 0.4

mixture is x+5 pounds that is 25%. 25%= 0.25

Subtract .25x from both sides

Subtract 1 from both sides

divide both sides byu 0.15

x=5/3 pounds

Volume (cone) = (1/3)πr²h, at the same time Volume (cone)=30π

(1/3)πr²h=30π,
If the height  is multiplied by 6, we will need to multiplied by 6 both sides of the equation (1/3)πr²h=30π.

(1/3)πr²*(6*h)=6*30π
So the volume of the new cone is going to be
 Volume (new cone)=6*30π =180π
