Chapter 337 Two voices sounded in the arena at the same time.

After 5 tense minutes, the morning team competition of the four-school league officially began.

"It's finally time for the long-awaited team competition. Here I will tell you the rules of the team competition."

Teacher Zhang continued: "Look at the questions that appear on the big screen for a while. After reading the questions and making an answer, each contestant rushes to answer. If the answer is correct, points will be added. If the answer is wrong, points will be deducted."

"I hope that every contestant will read the questions seriously, and try to solve the questions so that the answers are correct when they rush to answer."

Teacher Liu said: "Then the team competition has officially started now, and all the contestants are invited to watch the big screen in front of them."

In the competition field, a big screen appeared in front of the contestants. After Teacher Liu finished speaking, a question appeared on the big screen.

The content of the topic displayed on the big screen is:

In the eight numbers 2, 4, 6, 7, 8, 11, 12, 13, take any two constituent fractions. How many of these fractions are approximate fractions.

After seeing the topic, all contestants were very excited.He picked up the carbon pen placed next to the draft paper, and analyzed the answer to the problem of calculus on the draft paper.

Only two people in the field did not move, but glanced at the question above, and then looked at each other and smiled.

Then in the next second, both of them pressed the buttons in front of them respectively.

Two voices sounded in the arena at the same time.

The two narrators are the two voices.Attracted, and then looked towards the place where the sound came out, and saw those two.

"Oh, it's the contestants He Yang and Lin Sheng from High A," Teacher Liu said after seeing who rang the bell, "It's just that if the two of them rang first, it seems to me that two people rang at the same time, then Let the referee speak."

The referee this time: "A Gao He Yang."

He Yang, who heard his name being called, smiled and made a v sign, looked at Lin Sheng, and then said the answer to the question into the microphone in front of him: "36."

"Okay, let's see if player A's answer is correct."

"Congratulations to player A, He Yang, for logging in to this topic, plus 10 points."

When they heard that the school got the score, there was a lot of cheers from the auditorium of High A.

When preparing to read the second question, a person asked He Yang, "He Yang, how did you know the answer to that question so quickly?"

"The question just now was quite simple," He Yang continued, "I told you about the question just now last night, and I also led you to do similar questions."

Any integer in 7, 11, 13 and any integer in 2, 4, 6, 8, 12 constitute the approximate fraction, and there are 30 kinds.

Then according to the above idea, calculate the remaining 6 kinds.

So the correct answer is 36.

After listening to the answer, the man was very shocked.Although he participated in it yesterday, he probably didn't pay much attention to it and skimped on this question.

It may be because he is a senior in the third year of high school. Last night, he was teaching himself some knowledge points to someone who was a year younger than him. This made his self-esteem unable to let go, so he didn't listen much that night.

When he thought this way, he immediately started to prepare for the second question of the team competition.

In △ABC, AB+AC=7, and the area of ​​the triangle is 4, what is the minimum value of sin∠A.

This time, two voices sounded at the same time, the same two people from before.

The people in the other three schools were shocked, only the people in this school were not very shocked.

"I invite Contestant Lin Sheng to answer."
