The fair committee wants to decorate each ride with 40 balloons. There are 13 rides. If balloons come 24 to a package, how many packages will be needed?

22

Step-by-step explanation:

This is the closest number you can get to the exact amount before you either go way to much or way to little. We know that 40 times 13 equals 520 balloons. And 24 times 22 will get you 528 which is the closest number you can get to 520

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
