Copper
(dimes X 10) + (nickels X 5) = 145 and dimes - nickels = 4 14 dimes + 1 nickel =145 13 dimes + 3 nickel =145 12 dimes + 5 nickel =145 11 dimes + 7 nickel =145 10 dimes + 9 nickel =145 since 11-7 = 4 11 dimes + 7 nickels =145
Dimes minted before 1965 are made of 90% silver and 10% copper. Dimes minted after 1965 are made of a copper core with a outer layer of nickel.
Modern copper-nickel dimes weigh 2.27 gm. Older (1964 and earlier) 90% silver dimes weighed 2.5 gm.
Present day nickel, dimes and quarters are composed of copper and nickel.
6 dimes and one nickel make 65 cents, which is $0.65,0.65
Two quarters and another coin is a nickel. Only one of them has to not be a nickel, so that would be the quarter.
Four dimes one nickel two pennies are worth 47 cents
6 dimes, 6 pennies; or 6 dimes, 1 nickel, and a penny.
15 nickels 16 dimes
6 dimes = 60 cents and 1 nickel = 5 cents; so 5/60 = 0.08333...., or 8.33%
you can't buy a nickel. It's change you can get back. There's no buys nickels, dimes, pennies, or quarters. It's just change. Lawls literal epic fail sir. im pretty sure they were asking about the element nickel, Ni, not the currency.
Starting in 1965 US dimes are made of a Copper-Nickel alloy (.750 copper & .250 nickel) bonded to a core of pure copper.
