Let me ask you a very interesting question?????

0 men. 40 women, 60 children;

or 5 men. 32 women, 63 children;

or 10 men. 24 women, 66 children;

or 15 men. 16 women, 69 children;

or 20 men. 8 women, 72 children;

or 25 men. 0 women, 75 children.

The solution is as follows: there are x men, y women, and z children.

There is x+y+z=100

3x+2y+z/3=100

0<=x,y,z<=100

Eliminate y, got. 0<=x+z,x,z<=100

3x+2(100-x-z)+z 3=100, that is, x=5z 3-100 eliminate x, get. z is a multiple of 3.

0<=5z 3-100<=100, get 60<=z<=1200<=8z 3-100<=100, get <=z<=750<=z<=100

Therefore z = 60, 63, 66, 69, 72, 75

x=0,y=40,z=60

x=5,y=32,z=63

x=10,y=24,z=66

x=15,y=16,z=69

x=20,y=8,z=72

x=25,y=0,z=75

25 men. 0 women, 75 children.

Let men, women, and children be x, y, and z respectively

Rule. x+y+z=100 (1)

3x+2y+z/3=100 (2)

2)*3-(1) yields 8x+5y=200

y=40-x*8/5

Because y is an integer, x is a multiple of 5, and because y is > 0, x=5, 10, 15x=5, y=32, z=63

x=10,y=24,z=66

x=15,y=16,z=69

Equivalent to the amount of food for 300 children, man x, woman y, child z, 3*3x+2*3y+z=300

9x+6y+z=300

and x+y+z=100

Subtract 8x+5y=200

8x=200-5y

x=25-5y 8 (only y=8,16,24,32; It must be a multiple of 8, otherwise there is a decimal, and the other cannot be 40, so that the man is 0).

If y=8, then x=20, z=72

If y=16, then x=15, z=69

If y=24, then x=10 and z=66

If y=32, then x=5, z=63

Because I don't understand what you mean, but if he touches a converter, the difference between a DA converter and an AD converter is as follows: The meaning is different: DA converter is digital to analog, and AD converter is analog to digital.

The types are different: the DA converter output is analog, and the AD converter input is analog. Works differently:

A DA converter converts a binary digital signal in a computer into an analog signal for use by an analog circuit. An AD converter converts an analog signal from an analog circuit into a digital signal from a computer. Hopefully, the above information about the difference between DA converter and AD converter can help you use it better in your daily life.

Ask a question.

If you have any questions, you can also ask us directly.

Is there a difference between the two?

Is there a difference between the nabla operator point multiplied by the magnetic vector potential and the magnetic vector potential point multiplied by the nabla operator?

Kiss <>

The results of the nabla calculation as the macro symbol point multiplication of the magnetic vector potential and the magnetic vector potential point multiplication of the nabla operator are the same, because they can be used interchangeably with the a· ( b) =a)·b1。 where A represents the magnetic vector potential, B represents the magnetic vector potential, and the Nabla operator represents the gradient operator.

Summary. (3) InterceptionGenerally speaking, the answerer should let the questioner explain clearly before making it. However, in some special cases, as soon as the other party finishes speaking, some kind of secret will be revealed, which is difficult to clean up; Or answer the question, which is difficult to deal with.

Therefore, estimating the content of the other party, and in the case that the other party has not finished speaking, intercepting the conversation and answering it quickly can divert the attention of other listeners, and second, it can make the questioner have some understanding, change the topic, and pave the steps to facilitate the round. <>

Interesting question.

Hello, there are several ways to ask interesting questions, <>

(1) Wrong answerWrong answer is a method of answering the wrong way to deliberately explain the content in the wrong direction. Wrong answers are not a way to respond in scientific debate, but as a linguistic skill, it is very clever to get rid of unnecessary troubles and entanglements. <>

(2) Pushing and answering people often encounter indiscreet or deliberately embarrassing questions or conversations, which requires the respondent to use his mind skillfully and wisely to plan what he wants, "that is, to treat others in the way of others", and push back the words of the other party according to the other party's words, so that they can be cocooned and self-bound, so as to obtain unexpected results. <>

Summary. Hello!

Hello, I would like to ask a question.

Hello! What do you want to ask?

This question. Good.

Please wait a minute.

That's an old question. According to the final result, each person actually paid 9 yuan, and the three of them totaled 27 yuan, 27 = 25 (the accommodation fee charged by the boss) + 2 (the money hidden by the waiter), the two yuan of the waiter has actually been included in the 27 yuan, and there is no point in using it to add 27 yuan, so there is no formula of 27 + 2, there is no loss of any money in the transaction process, on the surface, it does seem that there is indeed 1 yuan lost, but in fact, it is only 27+The equation of 2 is misleading, and the person who wrote the question wants to confuse the equation of 27 (accommodation fee + money from the waiter's store) + 2 (money hidden by the waiter) = 29 (meaningless result) with 27 (accommodation fee + money hidden by the waiter) + 3 (money received by the guest) = 30 yuan (the total amount of money that appears at the beginning of the question).

In fact, the three people did not only pay 9 yuan, but used yuan. It's just that this question has misled people, and if you think about it, you will figure it out!

You ask and see if I can fix it.

So why can you say that? I'll try to satisfy you, but I'll say ...... you're there

Ask, I can answer anything...

What about the topic? How to answer the question.

What is the problem, hurry up and say that I am in a hurry.

What's the question? If you don't tell me, how can I help you?

It is an isosceles right triangle with a hypotenuse of 18cm

Half of the hypotenuse is 9cm

The hypotenuse midline is 9cm

The hypotenuse midline is the diagonal of the square.

The side length of the square is: (9 root number 2) 2

That's 9/2 times the root number 2

How much does it cost to ask a question.

He paid 300 yuan for the question, and he went back for 60 yuan. I paid 180 yuan, and I went to ** 90 yuan, how much more money do I have to pay?

Answering that he paid 300 yuan, he went back to see 60 yuan. That's only 240. I paid 180 yuan, and I went to ** 90 yuan, that is, I only paid 90 yuan How much else do I have to pay?

It depends on how you define how much money you have to pay, if I have to pay as much as he does. Then I need to pay 50

Say, I can answer any question, except for a few yuan and several equations.

I'll do that if you say it's the question.

There are ten people in front of Lele and eight people in the back, how many people are in this team?
