Answer:
90 nickels and 15 dimes
Step-by-step explanation:
If one is six times the other, then you would have 7 equal piles. Divide 105 by 7 to get 15 which is the number in each pile(number of dimes). Then 105 minus 15 gives you the total of the rest of the piles(number of nickels).
Check:
90 plus 15 equals 105, and
15 times 6 equals 90.
Answer:
455 possible ways
Step-by-step explanation:
We are told that 15 women are trying out for parts in a production of snow white.
Now, we want to find the number of ways that 3 women can be selected to play.
This is simply a combination question.
Thus;
Number of ways = C(15, 3) = 15!/((15 - 3)!(3!) = 15!/(12! × 3!) = (15 × 14 × 13 × 12!)(12! × 3 × 2 × 1)
12! will cancel out to give;
(15 × 14 × 13)/6 = 455
