Can anyone help me answer a question. Can anyone help me answer this question?

No. Gambling is always bad

I accept. I think so. It's hard to find someone with the same birthday as me. There are so many people now, and if it's really the same birthday, I think I'm very lucky.

This kind of coincidence can't be bought with money. And what about giving money.

You have to make sure who is giving you the 2 yuan, is it your friend or the person you bet on to attend the party, is it a little blurry? Did your friend accurately state that he was the one who gave the money? If not, he still flashed his words, I guess your friend will not be referring to himself, if so, you will not get a penny, because those people did not participate in your and your friend's gambling game, so, you only have to lose money, at this time you should refuse!

The income is greater than the output, and it can be played.

No. It's a math problem.

Or maybe he knows there's someone here who has a birthday with you.

Hello: My answer depends on the situation.

Your question is interesting.

If it's female. Just promise her. How naïve women usually are. Whether you lose or win, he is happy, and you don't have much to lose.

If it's a man. It seems that the chances of joking with you are higher. Because.

Win or lose, give him money. Although you don't have to take some money to heart. But there's no need to waste it.

Even if you didn't bet on him, he wouldn't be angry. Can't you call it a man?

Yes, because it is rare for two birthdays to be on the same day. Each person takes 1 yuan more, and has 16 + 2 yuan to earn, which is considered to bury your friends.

The topic itself is not difficult, it is the confusion of thinking that causes the strange results. Each person actually paid 9 yuan (10 yuan per person first, and then 1 yuan per person was refunded), so the three actually paid a total of 27 yuan. There's nothing wrong with that.

The key problem is that please note that the 2 yuan that the waiter hid is already included in the 27 yuan. In other words, of the 27 yuan, 25 yuan paid for the accommodation, and 2 yuan was hidden by the waiter. Therefore, 27 yuan plus 2 yuan is a meaningless equation, which is unreasonable, purely misleading, and causes confusion in thinking.

So, if you want to talk about the relationship between 27 yuan and 2 yuan, it is the relationship between 2 yuan and 27 yuan. It can be said that 27 yuan minus 2 yuan, that is accommodation money, but in any case, it cannot be said that 27 yuan plus 2 yuan. 2 yuan is already included in 27 yuan, what else to add?

If you want to calculate back the original 30 yuan, it should be 27 yuan (actually paid by the three people) plus 3 yuan (refunded by the three people), which is the original 30 yuan. **What's the problem of missing 1 yuan?

A total of 27 yuan was spent on the 3 of them, and the waiter's 2 yuan was within the 27 yuan.

This is not 9 yuan per person.

Pay 30 and return 5 yuan, indicating that there are 3 people, two people pay 8 yuan, one person pays 9 yuan, the waiter takes 2 yuan, saves 3 yuan, and finally it is equivalent to two people paying 9 yuan, and one person paying 10 yuan. So it's a misboot.

That's not a problem! The logic itself is wrong!

This question is not difficult, but the 9 yuan that appeared later is easy to confuse the thinking, and the correct algorithm is: accommodation fee 25 yuan + 2 yuan for the waiter + 3 yuan for return.

It can't be calculated as 27+2, it should be 27-2 for 25, so the total cost is 25 yuan.

I'm here to say it's a calculation error. I've had this problem before, 9 fast per person is 27, but instead of adding 2 fast, add 3 fast refunds, and use 27 plus 3 fast 30 that is useless. The 2 is the 27 that has been paid.

That's the right solution.

You'll get into it if you follow the idea of the question.

Each of the three people has one dollar in his hand.

Waiter 2 yuan.

Owner 25 yuan.

Not exactly 30

Pay 25 yuan, and the boss asks the waiter to refund 5 yuan. 1 yuan per person, and 2 yuan plus waiter is 30 yuan.

It's an old question. The actual room fee is 25 yuan, and the waiter hides 2 yuan, a total of 27 yuan; "The remaining 3 yuan was distributed to the three people, and each person received 1 yuan, 25 + 2 + 3 = 30

If there is an opportunity to make a lot of money in the future, as long as you win it, it is possible to eat, drink and be free for a lifetime.

Do you think you'll share this opportunity with others? Do you think you can grasp it with your current attitude? Do you feel like you're capable enough?

You don't. So child, the root of the problem is that you have no culture, no knowledge, no education, and no ability.

If you want to change all this, start with these questions, conquer it like a warrior, this is just the beginning, you will encounter many difficulties in the future, only if you conquer it again and again, defeat it, you will live the life you want.

Solution: width = 50 1 2 = 25m

1）s=2×50×

A: 1625m tiles need to be pasted.

2）v=50×25×

A: The volume of water is 1875m

Here is the hint for you, calculate the surface area = one base area + 4 side areas. ‍

I don't know if it's right or not, oops.

140+60)x2x3÷10＝120(m)

This question has been a long time, think about it carefully, the waiter should give them 5 yuan should not be 3 yuan, because this is taken by the waiter, not the boss's, in theory, it should not be used to get only 3 yuan per person, but should be 25 + 3 = 2, the main thing here is that the waiter's money cannot be counted on the boss.

This, this.
