Answer:

20%

Step-by-step explanation:

Use the percent change formula: difference = % * original cost

12 - 10 = 2

The difference is 2 and the original cost is 10. Now, we have the equation

2 = % * 10. We don’t know the percentage right? So now we have to find the percentage. To do this, you will have to do 2 divided by 10, which is 0.20. Lastly, we have to turn 0.20 into a percentage by multiplying it by 100, leaving you with 20%. So therefore, 20% is the percent increase. Hope this helps!

A right circular cone is intersected by a plane that passes through the cone's

yarga [219]

Answer:

B. A pair of intersecting lines

Step-by-step explanation:

The attached image can give you an idea of what you get when a plane perpendicular to the base of a cone intersects the vertex of the cone.

In the problem statement here, we assume a double-napped cone with no defined base. That means the lines of intersection with the sides of the cone will meet at the vertex point and extend indefinitely in either direction.

The intersection is a pair of intersecting lines.
