Step-by-step explanation:

2 fractions (ratios) in the form a/b and c/d are equivalent if it's verified the following relation:

a·d = b·c

Let's see!

1) 4·7 = 3·7 False. They are not equivalent.

2) 9·4 = 18·2 True. They are equivalent.

Each football is sold for $9.95. To make one of these football costs $7.10.
There is a profit of $2.85. Divide 11,400 by 2.85 to see how many footballs would have to sell to break even.

11,400 / 2.85 = 4000.

4000 footballs would have to be sold to break even.

How do you use the triangle sum theorem to find the measure of each angle in degrees ?!

TEA [102]

Answer:

The Triangle Sum Theorem is also called the Triangle Angle Sum Theorem or Angle Sum Theorem. It says that all the angles inside a triangle add up to 180°.

---------------------------------------------------------------------------------

Take a look at the picture attached. It has a "formula": ∠a+∠b+∠c=180°

Use this as it will help you a lot. You plug in the info you already know (it doesn't matter which angle is a,b,c) and solve for the missing one. :)

Ask in the comments below if you are not sure about something.

I hope that helps you! :D
