Answer:
220
Step-by-step explanation:
There are 6 comedies and 12 non-comedies. He wants all 6 of the comedies, and 3 of the non-comedies.
The number of ways he can choose 6 comedies from 6 is ₆C₆ = 1.
The number of ways he can choose 3 non-comedies from 12 is ₁₂C₃ = 220.
So the total number of combinations is 1 × 220 = 220.
The answer is 0.7. I am positive
X = number of dimes
x + 2 = number of nickels
3(x + 2) = number of pennies
10x + 5(x + 2) + 3(x + 2) = 52
10x + 5x + 10 + 3x + 6 = 52
18x = 36
x = 2
x = 2 (number of dimes)
x + 2 = 4 (number of nickels)
3(x + 2) = 12 (number of pennies)
Check:
2(10) = 20 cents in dimes
4(5) = 20 cents in nickels
12(1) = 12 cents in pennies
Total = 52 cents
