Answer:
 .
.
Step-by-step explanation:
Since repetition isn't allowed, there would be  choices for the first donut,
 choices for the first donut,  choices for the second donut, and
 choices for the second donut, and  choices for the third donut. If the order in which donuts are placed in the bag matters, there would be
 choices for the third donut. If the order in which donuts are placed in the bag matters, there would be  unique ways to choose a bag of these donuts.
 unique ways to choose a bag of these donuts.
In practice, donuts in the bag are mixed, and the ordering of donuts doesn't matter. The same way of counting would then count every possible mix of three donuts type  times.
 times. 
For example, if a bag includes donut of type  ,
,  , and
, and  , the count
, the count  would include the following
 would include the following  arrangements:
 arrangements:
Thus, when the order of donuts in the bag doesn't matter, it would be necessary to divide the count  by
 by  to find the actual number of donut combinations:

Using combinatorics notations, the answer to this question is the same as the number of ways to choose an unordered set of  objects from a set of
 objects from a set of  distinct objects:

Answer:
I'm going to say C
it looks the most reasonable to me
 
        
             
        
        
        
First you would put both numbers into improper fractions.
3 1/3 = 10/3 and 2 1/4 = 9/4
Multiply 10/3 * 9/4
10*9 = 90 and 3 * 4 =12
So 90/12 is your fraction. Reduce it, 7 6/12
7 6/12 = 7 1/2
So your answer is 7 1/2

Answer:
OF
Step-by-step explanation:
Since the arcs are congruent, the lines intercepting them are congruent, and you will get 2 congruent right triangles. So OA is congruent to OF by CPCTC.
