Acollection of dimes and nickels is worth $5.60. the ratio of dimes to nickels is 3: 2. how many dimes and how many nickels are there?

There are 42 dimes and 14 nickels there if the collection of dimes and nickels is worth $5.60

First, we need to convert dimes and nickel to pennies to have:

1 dime = 10 pennies

1 nickel = 5 pennies

Since the ratio of dimes to nickels is 3:2, this shows that we have 30  dimes and 10 pennies

Total pennies  = 30 + 10 = 40 pennies

Since the total collection of dimes and nickels is worth $5.60, this means that the total collections in pennies are 560 pennies ($1 is 100 pennies)

Number of pennies for the ratio of 30 = 30/40 * 560

Number of pennies for the ratio of 30 = 420

Number of dimes = 420/10 = 42 dimes

Number of pennies for the ratio of 10 = 10/40 * 560

Number of pennies for the ratio of 10 = 140

Number of nickel = 140/10 = 14 nickels

Hence there are 42 dimes and 14 nickels there if the collection of dimes and nickels is worth $5.60

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.

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 !
