Example Question #301 : New Sat

Tangents

In the above diagram,  has length . Give the radius of the circle to the nearest whole number.  

Possible Answers:

The question cannot be answered with the information given.

Correct answer:

Explanation:

Call . The measure of the corresponding major arc is  

If two tangents are drawn to a circle from a point outside the circle, the measure of the angle they form is equal to half the difference of the measures of their intercepted arcs; therefore

Substituting:

Therefore, . Since  has length , it follows that if  is the circumference of the circle, 

Divide the circumference by  to obtain the radius:

.

This makes 47 the correct choice.

Example Question #304 : New Sat

Julie has  coins, all dimes and quarters. The total value of all her coins is . How many dimes and quarters does Julie have?

Possible Answers:

 quarters and  dimes

 quarters and  dimes

 quarters and  dimes

 quarters and  dimes

 quarters and  dimes

Correct answer:

 quarters and  dimes

Explanation:

Let  be the number of dimes Julie has and  be the numbers of quarters she has. The number of dimes and the number of quarters add up to  coins. The value of all quarters and dimes is . We can then write the following system of equations:

To use substitution to solve the problem, begin by rearranging the first equation so that  is by itself on one side of the equals sign:

Then, we can replace  in the second equation with :

Distribute the :

Subtract  from each side of the equation:

Divide each side of the equation by :

Now, we can insert our value for  into the first equation and solve for :

Julie has  quarters and  dimes.
