How many ways are there to use a sufficient amount of one cent, five cents, and one dime to make up

This step is wrong!

It should be: (1+3+5+...)37)=(1+37)*19 2=361The final answer should be: 3+39+19+19+361 441 This method is too complicated, and it can be counted directly by the number of a corner:

0 corners: 5 points have 0 to 40 for a total of 41 kinds (the remainder is made up with 1 point, so there is no need to consider 1 point, the same below).

1 corner: 5 points, 0 to 38, a total of 39 types.

2 corners: 5 points, 0 to 36, a total of 37 types.

20 dimes: 5 points only 0 1 kind.

Total: 1 3 5 ...41 441 species.

1 gross 5 points 1 point.

19 0-2 10-0 (take a multiple of 5).

18 0-4 20-0 (in multiples of 5).

0 0-40 200-0 (in multiples of 5).

Total n=1+3+5+......41=441

The last step: 37+35+33+.11 + 9 + 7 + 5 + 3 + 1 = 361 has 1 corner 1 1 5 points need 185 1 points, 2 5 points need 180 1 points... 37 5 points require 5 points for a total of 36 types (the same below).

There are 35 kinds of one corner of two.

There are 33 kinds of one corner of three.

And so on.

The sum of three and four is 19*2 and one of the corners is split into two fives or five fives.

Answer]: A 1 cent, 2 cent, and 5 cent coins can be used to make up a dollar, and 2 cents and 5 cents can be used to make up no more than one dollar. Thus, this question translates to:

There are 50 2-cent coins and 20 5-cent coins, and there are many different ways to make up no more than one dollar. ”

According to the number of 5 cents coins, there are 21 categories of counting:

If there are 20 5-cent coins, there is obviously only one way to make them;

If there are 19 5 cents, then the value of the 2 cents is not more than 100 5 19 5 (cents), so the 2 cents can be 0, 1 or 2, i.e. there are 3 different ways to make up the coins.

If there are 18 cents of the 5 cents, then the value of the 2 cents does not exceed 100 5 18 10 (cents), so the 2 cents can be taken 0, 1, 2, 3, 4 or 5, that is, there are 6 different ways to make it;

If we continue like this, we get a total of different ways to make up the following: 1 3 6 8 11 13 16 18 21 ....48 51 5 (1 3 6 8) 4 (10 20 30 40) 51 90 400 51 541 (species).

541 (species).

Answer: There are 541 ways to make up for it

Assuming that there are 20 pennies, there are no pennies, so there is only one way to make up them. Suppose there are 19 cents of coins with a value of 5 19 = 95 cents, so that the total value of the coins does not exceed 1 yuan = 100 cents, the value of the two cents coins cannot exceed 5 cents. Obviously, the number of pennies can be 0, 1, or 2, and there are three different ways to make up the sample.

If we continue like this, we can see that there are different ways to make up the scale.

1＋48）＋（3＋46）＋（6＋43）＋…Let high (23 + 26) + 51541 (species).

A: There are 541 ways to make up for it.

Summary. Hello, glad to answer for you.

There are three ways to do this.

In your own way, we have three ways to make up five dollars.

The first. Six dimes for 3 bucks. Then add two more one-dollar ones. That's five bucks.

The second. Two pentagonal ones plus five one-dollar ones.

The third. Four of the five cents. Plus three of the unned.

Hope mine helps you.

At the same time, I wish you good luck in your studies.

6 pentagons, 5 yuan, how many ways to make up 5 yuan?

Hello, I'm sorting out the answers based on your questions, please wait a while oh so slow. Cheating money.

Immediately typing. 

The cucumber dishes are cold.

**, cheat money.

Hello, glad to answer for you.

At the same time, I wish you good luck in your studies.

Hope to ask questions, don't rush. If you have any questions in the future, just come to me. I will patiently answer for you. 

I'll rearrange it for you, you were in too much of a hurry just now.

There are four methods.

1, five of a dollar. It's five dollars.

2. Four of the one yuan plus two pentagonals.

3. Three of the one yuan plus four pentagonals.

4. Two of the one yuan plus six pentagrams.

I hope you will refer to it carefully.

It's a bit too rushed. It's a bit messy. 

There are 3 ways to make up:

1.Use 6 Pentagon-wide coins;

2.Use 5 one-dollar coins;

3.Use 1 pentagonal hard and thick Biliang coin, and count and grind 4 one-dollar coins.

Analyze with 1 point, 2 points, and 5 points hard.

The source coin is not more than 1 yuan and 2 cents and 5 cents coins.

The number of zhi methods of over one yuan is the same, and if it is not enough, it should be filled in with 1 point. So, this question translates to: "There are 50 2-cent coins and 20 5-cent coins, how many different ways are there to make up no more than one yuan?"

Solution: 21 categories according to the number of 5 cents coins; If there are 20 5-cent coins, there is obviously only one way to make them; If there are 19 cents of 5 cents, the value of the 2 cents does not exceed 100-5 19 = 5 (cents), so the 2 cents can be taken 0, 1, or 2, that is, there are 3 different ways to make up the coins; If there are 18 cents of 5 cents, the value of the 2 cents does not exceed 100-5 18 = 10 (cents), so the 2 cents can be taken 0, 1, 2, 3, 4, or 5, that is, there are 6 different ways to make it; …If we continue like this, we get a total of different ways to make up the following: 1 3 6 8 11 13 16 18 21 ....48 51 5 (1 3 6 8) 4 (10 20 30 40) 51 90 400 51 541 (species).

If there is a 5-cent coin.

20 bai, apparently there is only one way to make up du; If there are 19 coins in 5 cents, the DAO value of 2 cents coins does not exceed 100-5 19 = 5 (cents).

version, so 2 cents coins are advisable.

0, 1, or 2, i.e. there are 3 different ways to make up;

If there are 18 cents of 5 cents, the value of the 2 cents does not exceed 100-5 18 = 10 (cents), so the 2 cents can be taken 0, 1, 2, 3, 4, or 5, that is, there are 6 different ways to make it;

If you continue like this, you can get different ways to make up for it

541 (species).

First use all 5 points, then reduce the number of 5 points each time, and replace them with points.

Leave the process to yourself.
