Look below

Step-by-step explanation:

I'm not sure what the question is, but if you're looking for what percentage of the coin is nickel or copper, you can multiply 25 by 4 to get to 100%. Then multiply 9 or 16 by 4 and you get 36 or 64. Therefore, there is 36% nickel in the coin and 64% copper. Let me know if this was your question! :)

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
