According to the United States Mint, the mass of 1 nickel is 5.000 g.

There are 15 nickles in 75 cents worth of nickels.
15 * 5.000 g = 75.000 g
Answer: 75.000 grams
Answer:
31/42
Step-by-step explanation:
there are 42 students in 8th grade
31 dont play keyboard so 31/42 = 73.8% chance
(-2)^4 = (-2) (-2) (-2) (-2) = 16
so n = 16
21 times 9 which equals 189 feet and there are 3 feet in a yard so we do 189 divided by 3 which equals 63 so the answer is 63 square yards.
