The solution to the problem is as follows:
If there are 6 pairs of shoes:
C(6,1) = choose the matching pair = 6 choices.
C(10,1) = 1 shoe from the other 10.
Now you cannot choose the mate of that one,
so you have 8 other shoes to choose from.
6 * 10 * 8 = 480 choices of "4 shoes".
But then we must divide by 2, because the last two shoes
could be chosen in either order.
That gives 240 choices - same as your teacher's answer,
<span>but via a different route.

the answer is #2
Step-by-step explanation:
Step-by-step explanation:
- area of a semicircle=1/2(πr^2
- =1/2×22/7×6^2
- =56.54
In order to find the answer to this question, you would need to find the Greatest Common Factor of 16 and 12 which would be 4 because 4 is the greatest amount that you can divide both 12 and 16 by. So the soonest both ships will leave together again will be in 4 days.
