Answer:
Sharing cone holds 9 times more popcorn than a skinny cone.
Step-by-step explanation:
Height of each cone = 9 inches
Radius of the sharing size cone = 3 times radius of the skinny size cone
Let the radius of skinny size cone = r
Then radius of the sharing size cone = 3r
Volume of the sharing size cone =
=
= 27πr²
Volume of the skinny size cone =
=
= 3πr²
Ratio of the volumes =
=
= 9
Therefore, sharing cone holds 9 times more popcorn than a skinny cone.

Answer:
Step-by-step explanation:
Given the following system of equations:
In order to solve the system of equations using the Elimination Method, you can follow these steps:
- Multiply the first equation by -6 and the secondd equation by 4.
- Add both equations.
- Solve for "y".
Then:
- Substitute the value of "y" into one of the original equations and solve for "x":
