Answer: Option A.
Step-by-step explanation:
 The angle ∠QST and the angle ∠QSR are supplementary.
 If two angles are supplementary, means that the sum of both angles is 180 degrees.
 Thenrefore
 
 Solve for the angle ∠QSR and substitute the value of the angle ∠QST  to find the value of the angle ∠QSR. Then, solving the equation, you get:
  
 
 Then  is:
 is:
 
 This matches with the option A.

Answer:

So then we have that Morten Andersen scored on average 97.45 points per year in his career. 
Step-by-step explanation:
Assuming the following table on the figure attached. 
We see that the career points for Morten Andersen was 2437. That include all the points over alll the years the he played in the NFL.
Since the total years played by Morten Andersen was 25 we can write the following equation:

Where  represent the rate of points average per year.
 represent the rate of points average per year.
If we solve for r from the last equation we can divide both sides of the equation and we got:

So then we have that Morten Andersen scored on average 97.45 points per year in his career. 
 
        
             
        
        
        
Answer:
$2100
Step-by-step explanation:
I = prt
I = $1500(0.05)(8)
I = $1500(0.4)
I = $600
$1500 + $600
= $2100
