What is wrong with 10,11 questions Is 11 questions done right? Correct the mistake, thank you

11. In recent years, Japan has accelerated the expansion of overseas investment, taking into account such aspects as long-term development strategy, exporting and exchanging technology, occupying and controlling overseas markets, and protecting the environment of its own country Most of the enterprises that have relocated to Japan are enterprises that consume a lot of resources, enterprises that need a lot of labor, and enterprises that are more polluting

Japan is small in size, and moving heavily polluting to other countries not only protects the environment, saves resources, but also makes money.

I can't see it clearly, Lao Tie.

Xiaopang set off for 1 minute, and it takes 1 minute to return to Li Shu, and stay for 2 minutes. It took 4 minutes.

That is, Xiao Ding set off 4 minutes earlier than Xiao Pang.

Let's say Chubby used the bad beat for x minutes.

65（x+1+1+2）+75x=1940

140x=1940-65*4

140x=1680

The time of x = 12 small dices is 12 + 4 = 16 minutes.

Solution: Let this and the pencil have x bindings, the four binds have a bundle, and the six binds have a b-bundle. （a＞0，b＞0)

Then the game: x=4a+2=6b+(6-2).

4a+2=6b+4

Obviously, when Tongbianyan a=2 and b=1, the equation holds left and right.

At this point x=10

Answer: Brother Qi's box of pencils is at least 10.

4, s=s outside - s inside = r outside - r inside = *6Perimeter =

Circumference = d = d = 10cm

9.Perimeter = r + 2r, s = 1 2 r

The rest is right.

False, correct answer process: Solution: Original test 27a to the sixth power b to the fourth power - 3a to the second power b to the fourth power a to the fourth power 27a to the sixth power b to the fourth power - 3a to the sixth power 24a to the sixth power b to the fourth power.

It is not difficult to deduce that the string pq = root number 20, which is approximately equal to.

Then the chord length radius is about =

Because the arc is longer than the chord length, the angular por is slightly greater than the radian.

Therefore, the answer of radian is the closest to estimation.

Your train of thought is hard and tortuous, but it's not bad, but the data is wrong:

5 sin90 degrees = 4 sin angle por

The sin angle por=4 5=, and the radian can be roughly inferred.

yes, it doesn't look like a problem.

Is it from the cosine to that angle.

The radian there was solved wrong, probably.

The others didn't find any problems with a at the end of the period.

zha'ku should be right like this.

cospor=You're not wrong. You're making a mistake of mistaking the cosine of the angle por for the radian of the angle por.
