Ricardo has 2020 coins, some of which are pennies (1-cent coins) and the rest of which are nickels (5-cent coins). He has at least one penny and at least one nickel. What is the difference in cents between the greatest possible and least possible amounts of money that Ricardo can have?

Answers

Answer 1

Answer:

The lowest amount would be (1 x 5) + (2019 x 1) = 2024 cents, or $20.24

The highest amount would be: (1 x 1) + (2019 x 5) = 10,096 cents, or $100.96

100.96 - 20.24 = 80.72

The difference in cents between the greatest possible and least possible amounts of money Ricardo can have is $80.72.

Answers

Answer:

1200

Step-by-step explanation:

Since the value they are asking for is in minutes, we need to convert seconds to minutes. We can do that by multiplying 4 and 60, because there are 60 seconds in a minute, and we need to find the value of one minute.  Also because the value they gave is 4. When we do this, we get 240. To get the final answer, we need to multiply 240 and 5, because 240 is the descending rate per minute, and they are asking for 5 minutes. When we do this, we get 1200.

Answer:

First week: 1.34      Original Cost: 3.35

Step-by-step explanation:

So you know how much the second week cost $1.34. So to find the first week you need to divide 40% with 100 to get .4, after getting .4 you need to get the second weeks cost and divide 1.34 to .4 and you get 3.35. That is your original cost. So when you divide 3.35 with .4 for the first discount of the first week you get 1.34

Sorry the second one is more confusing I just learned this last week so I'm sorry if I am wrong and I hope someone else follows on my answer.

peyton ran 4/5 of a mile in 1/8 of an Hour. What is Peyton's constant of proportionality in miles per hour?

Answers

Answer:

6.4 Miles Per Hour

Step-by-step explanation:

Let h be hours

Let mi be miles

We put this in equation form

4/5mi = 1/8h

In order to calculate the rate we would have to make h singular therefore we multiply both sides by 8

4/5mi * 8 = 1/8h * 8

= 32/5mi = h

= 6.4mi = h
