Does A or B have a strategy to ensure that they win?

You can win by taking it yourself first reasoning process.

Give the opponent one left, the opponent will definitely lose, because you can take 1 2 4 and draw each time, so, if you leave the opponent 2 3 5 you will lose, so you have to avoid leaving such a number and leave the opponent with a number like 4 6 7 9,In the same way, 8 10 11 13 should not be left to the opponent, while 12 14 15 is a choice that must be left to the opponent, so take it first

Whoever takes it later wins.

Backwards. Leave the opponent with a number like 4 7 10 13 and you will win, and you will win with 3 5 9 11 15, so the first hand is only 2 or 4, but the second hand can make the first hand get 13 10 so the second hand wins.

If there are 2 left, whoever takes first wins (take 1).

If there are 3 left, whoever takes first wins (take 2).

If there are 4 left, whoever takes first loses.

If there are 5 left, whoever takes first wins.

If there are 6 left, whoever takes first wins.

If there are 7 left, whoever takes first loses.

If there are 8 left, whoever takes first wins.

If there are 9 left, whoever takes first wins.

If there are 10 left, whoever takes first loses.

If there are 11 left, whoever takes first wins.

If there are 12 left, whoever takes first wins.

If there are 13 left, whoever takes first loses.

If there are 14 left, whoever takes first wins.

If there are 15 left, whoever takes first wins.

If there are 16 left, whoever takes first loses.

So the strategy is to take it later. Don't be careful every step in the future because they are very smart and don't make mistakes.

If it were me, I'd let the other person take it first.

Solution: (1) 30-x-y;

2) From the question: , so y=-2x+40;

3）q=q=，，=，；(4) From the meaning of the title, so y=-2x+40

From the meaning of the title, we can see that x 4, -2x+40 4, 30-x-(-2x+40) 4

x≥4，x≤18，x≥14，x≥12 8/21，∴14≤x≤18．q=1/100[6×

When Q is the largest, xmin=14, y=-2x+40=12, and the number of vehicles for C fruit is 30-12-14=4

Therefore, 14 vehicles are needed to transport A fruits, 12 vehicles are needed for B species, and 4 vehicles are required for C species

Solution: (1) From the problem: So y = 2x+40.........2 points.

x 4, y 4, 30 x y 4, get 14 x 18 .........3 points.

2）q=6x+8y+5（30－x－y）= －5x+170………5 points.

q increases as x decreases, and 14 x 18, so when x = 14, q gets the maximum value ,......6 points.

That is, q = 5x + 170 = 100 (100 yuan) = 10,000 yuan.

So, when x = 14, y = 2x + 40 = 12, 30 x y = 4 .........7 points.

Therefore, it should be arranged in such a way that 14 vehicles are used for wheat A, 12 vehicles are used for wheat B, and 4 vehicles are used for wheat CThe 8 points seem wrong!!

Solution: (1) From the problem: So y = 2x+40.........

2）q=q=，，=，；From the meaning of the title, so y=-2x+40

From the meaning of the title, we can see that x 4, -2x+40 4, 30-x-(-2x+40) 4

x≥4，x≤18，x≥14，x≥12821，∴14≤x≤18．q=1100[6×

When Q is the largest, xmin=14, y=-2x+40=12, and the number of vehicles for C fruit is 30-12-14=4

Therefore, 14 vehicles are needed to transport A fruits, 12 vehicles are needed for B species, and 4 vehicles are required for C species

There is a question to know.

The weight of a is tons.

b weighs .

The weight of c is 2 (30-x-y).

a+b+c=64

q=6*q=so the smaller the x, the better, the minimum x is 4, and when x is 4, the condition x=4 y=15 is satisfied

Solution: (1) From the problem: , so y=-2x+40, and because x 4, y 4, 30-x-y 4, then -2x+40 4, 30-x-(-2x+40) 4, get 14 x 18;

y≤x+30-x-y，y=-2x+40，∴x≥，14≤x≤18；

2) q=6, q increases with the decrease of x, and because 14 x 18, when x=14, q obtains the maximum value, that is, q=42640 (yuan) = 10,000 yuan).

At this time, it should be arranged as follows: 14 cars for fruit A, 12 cars for fruit B, and 4 cars for fruit C.

Choosing B, ACD in a sense, there are similarities. Among them, AD can be equated in several books. Directly excludable.

Reason: Tian Khan was the honorific title given to Tang Taizong by the leaders of ethnic minorities in the Tang Dynasty. Here's an example:

In the "Zhaoling" of Tang Taizong, there are several mausoleums of ethnic minority generals. For example, Ashina Sheer, the son of Luo Khan of the Turkic Division, He Li, the grandson of the Mohe Khan of the Tiele Department, and the Turkic chieftain Zhi Sili, were buried in Zhaoling after their deaths. This phenomenon was rare in the past, and it can be said to be a silhouette of Tang Taizong's ethnic policy.

In addition, add a point: In addition, in addition to Tang Taizong, Tang Gaozong and Tang Suzong were also called "Heavenly Khan".

Election B, the reason why Tang Taizong is called the Heavenly Khan: to win the hearts of the people with good policies.

A good look at the history books has the answers. He is very sympathetic to the people's feelings.

Pick B. Khan, is the name given to their leader by the nomads. During the reign of Taizong of the Tang Dynasty, the military power had a certain advantage, and in addition, he implemented an enlightened ethnic policy (the Tang Dynasty's management of the northern minority areas was mainly to appoint the upper leaders of various ethnic groups as local governors, without changing the original ethnic habits and lifestyles.

Their positions are hereditary, and they manage the local area on behalf of ****. In Taizong's later years, the various departments in the Mobei region were attached one after another. The leaders of the northwest tribes all came to Chang'an to meet and supported Tang Taizong as their common monarch.

Call it "Heavenly Khan".

None of them is because Tang Taizong respected the envoys sent by various countries and respected the culture of various places.

If he is strong, I will defeat him as soon as he is strong, and this is the ox x of the Heavenly Khan.

Huairou policy under the strong national strength and sufficient military protection.

The Tang Dynasty was strong, and its neighbors did not dare to fight the attention of the Tang Dynasty; at the same time, Tang Taizong adopted grace and power against the surrounding ethnic groups, and had no prejudice against the nation.

There are some reasons for the above, but in the final analysis, the first is the strength of the country, and the second is the charisma.

If you choose a single choice, you should choose B, but it has something to do with the military strength of the Tang Dynasty

Policy is the soul of the law, is the basis for formulating the law, and the law is the culture of the policy, so the answer should be A

B wins, if A beats B, is A winning?
