Four.

There are 13 different combinations. For any combination, the number of pennies P, nickels N, Dimes D, and Quarters, P + 5N +10D + 25Q = 25 (1, 5, 6, 1) where P = 0, 5, 10, 15, 20, 25 N = 0 to 5 D = 0 to 2 Q = 0 or 1 The combinations are 1 quarter 2 dimes and 1 nickel 2 dimes and 5 pennies 1 dime and 3 nickels 1 dime, 2 nickels, 5 pennies 1 dime, 1 nickel, 10 pennies 1 dime, 15 pennies 5 nickels 4 nickels, 5 pennies 3 nickels, 10 pennies 2 nickels, 15 pennies 1 nickel, 20 pennies 25 pennies

In each combination, you can have 0,1,2 or 3 pennies; you can also have 0 or 1 nickels, 0 or 1 dimes and 0 or 1 quarters. That is, 4 ways of picking the number of pennies, 2 ways of picking how many nickels, 2 for dimes and 2 for quarters. In all that makes 4*2*2*2 = 32 combinations. BUT, one of these combinations is where you have 0 pennies, 0 nickels, 0 diems and 0 quarters. Conventionally, a null combination such as this is omitted and so you have 31 valid combinations.

The minimum number of quarters, pennies, and nickels needed to make up 123 cents is 4 quarters, 4 nickels, and 3 pennies.

There are 12 different combinations using pennies, nickels and dimes. 25 pennies 20 pennies and 1 nickel 15 pennies and 2 nickels 15 pennies and 1 dime 10 pennies and 3 nickels 10 pennies 1 dime and 1 nickel 5 pennies and 4 nickels 5 pennies 1 dime and 2 nickels 5 pennies and 2 dimes 5 nickels 1 dime and 3 nickels 2 dimes and 1 nickel

Three quarters and a dime or two nickels. There are other combinations as well, such as 85 pennies.

Seven combinations that I can come up with: two dimes a nickel and three pennies all pennies two dimes and eight pennies a quarter and three pennies five nickels and three pennies three nickels one dime and three pennies two nickels one dime and eight pennies

no, but they do corrode

They sound different because they are different sizes and made of different metals.

10 quarters 7 dimes 9 pennies and 27 nickels is: $4.64

I am assuming this means what different combinations of coins would add up to 17 cents. You could have one dime, one nickel and 2 pennies, 1 dime, 7 pennies 3 nickels, 2 pennies 2 nickels, 7 pennies 1 nickel, 12 pennies 17 pennies

Just a few ways include... 79 pennies. 3 quarters and 4 pennies. 7 dimes, 1 nickel, 4 pennies. 7 dimes, 9 pennies. 15 nickels, 4 pennies. 2 quarters, 2 dimes, 1 nickel, 4 pennies. 2 quarters, 2 dimes, 9 pennies. 2 quarters, 5 nickels, 4 pennies. 2 quarters, 29 pennies.

2 quarters 3 dimes 8 nickels and 7 pennies equal $1.27

8 nickels 14 pennies 5 dimes and 6 quarters equals $2.54

Two quarters Three nickels Three pennies

5 pennies.

75 pennies 15 nickels

9 combinations. 23 pennies 1 nickel 18 pennies 2 nickels 13 pennies 3 nickels 8 pennies 4 nickels 3 pennies 1 dime 13 pennies 2 dimes 3 pennies 1 dime 2 nickels 3 pennies 1 dime 1 nickel 8 pennies

Among other possible combinations: 2 Quarters, 1 Dime, 4 Nickels and 20 Pennies

None. If you "get 65 cents using only dimes nickels and quarters" you are not using any pennies!

There are 2 solutions (if you include the non-use of quarters): 1 Quarter, 2 Dimes, 2 Nickels, 45 Pennies No Quarters, 2 Dimes, 8 Nickels, 40 Pennies

Among other combinations: 3 Quarters, 2 Dimes and 20 Pennies or 1 Quarter, 3 Dimes, 6 Nickels and 15 Pennies
