Answer:

336 miles

Step-by-step explanation:

First, you find an equation for this problem, which is y=64x. Next, you convert 5 hours and 15 minutes to 5.25 because of five full hours and the 15 minutes, which is 1/4 or .25 of 1 hour. Then, you substitute time into the equation y=64(5.25) and got y=336 miles that you have traveled.

Answer:

I would assume $10 is the cost of the booth and 5 is how much she earns for each T-Shirt, so the equation would be 5x-10=65. Assume $65 is what she earned.

Therefore, the equation may be: (your question did not specify) 5x-10=65. so x is 15. Therefore, she sold 15 T-Shirts.

Given:

A figure of a circle and two secants on the circle from the outside of the circle.

To find:

The measure of angle KLM.

Solution:

According to the intersecting secant theorem, if two secant of a circle intersect each other outside the circle, then the angle formed on the intersection is half of the difference between the intercepted arcs.

Using intersecting secant theorem, we get

$\angle KLM=\dfrac{1}{2}(Arc(JON)-Arc(KM))$
