Kevin and Randy Muise have a jar containing 56 coins, all of which are either quarters or nickels. The total value of the coins in the jar is $6.80. How many of each type of coin do they have?

36 nickels and 20 quarters

Step-by-step explanation:

36x5= 180

25x20=500

500+180=680=6.80

I won’t give you a full answer but I can explain it.

Step-by-step explanation: Our “goal” is $6.80 we have to figure out how many nickels and quarters are in it. First off, which is bigger? A quarter. Count as far as you can until you can’t go over 6.80. Now add the remaining numbers (the nickels) and you will have your answer. Make sure when your adding to count each quarter and nickel!

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
