Answer:

one binder for $3.70

Step-by-step explanation:

The cost of 5 binders and 3 folders = $23.00

The cost of 5 binders and 1 folder = $20.00   [ 2 folders less ]

Cost of 2 folders = 23 - 20 = $3.00

Cost of 1 folder = \frac{3}{2} = $1.50

The cost of 5 binders = 20.00 - 1.50 = $18.50

The cost of 1 binder = \frac{18.50}{5}

                                = $3.70

The cost of one binder is $3.70

In the image below, 10 is the long leg of the 30-60-90 triangle.<br><br><br> True or false?
never [62]

The measure of the angle between the hypotenuse and the <em>short</em> leg is 60° and we can conclude that the side with length 10 is not the <em>long</em> leg of the 30 - 60 - 90 <em>right</em> triangle. (Right choice: False)

<h3>Is the length of a known arm in a 30 - 60 - 90 right triangle the long arm?</h3>

In accordance with geometry, the length of the <em>long</em> arm of a 30 - 60 - 90 <em>right</em> triangle is √3 / 2 times the length of the hypotenuse, the length of the <em>short</em> arm is 1 / 2 times the length of the hypotenuse and the length of the <em>long</em> arm is √3 times the length of the arm.

Thus, the measure of the angle between the hypotenuse and the <em>short</em> leg is 60° and we can conclude that the side with length 10 is not the <em>long</em> leg of the 30 - 60 - 90 <em>right</em> triangle. (Right choice: False)
