I'd say you can't. If all the coins are the smallest possible without pennies, they must all be nickels, and 21 of them make $1.05 . So in order for 21 coins to be not more than $1.00, there must be some pennies.
To make a dollar using 25 coins, you would need a combination of quarters, dimes, nickels, and pennies. One possible combination could be 3 quarters (0.75), 2 dimes (0.20), 0 nickels, and 0 pennies. This totals $1.00. Another combination could be 2 quarters, 1 dime, 0 nickels, and 20 pennies. Each quarter is worth 0.25, each dime is worth 0.10, each nickel is worth 0.05, and each penny is worth 0.01.
(1) $0.50 (2) $0.10 (3) $0.05 (15) $0.01
In the game 21 Questions, coins are used to reveal who answered questions about you. There are two ways that you can collect coins: by playing the game or purchasing them.
One dollar can be made by adding the values of the following 21 U.S. coins: 10 pennies (10 ¢) 7 nickels (35 ¢) 3 dimes (30 ¢) 1 quarter (25 ¢) There are also many other possible configurations including: 10 pennies (10 ¢) 4 nickels (20 ¢) 7 dimes (70 ¢) and 5 pennies (5 ¢) 13 nickels (65 ¢) 3 dimes (30 ¢)
21 pennies
The number of ways to make 21 depends on the context, such as whether you are referring to combinations of numbers, coins, or other items. For instance, if using coins of different denominations, the number of combinations can vary based on the denominations available. In mathematics, particularly in combinatorics, generating functions or partition functions can be used to calculate the number of ways to express 21 as a sum of integers. If you specify the context or constraints, I can provide a more precise answer.
Fifteen pennies, three nickels, two dimes, one fifty-cent piece
