Ask for genius answers, ask geniuses for answers

As you can see from the title, there is a common 2005x2006, so you can put forward 2005x2006, that is, 2005 2006 (10001-10001) 0 I hope it can help you to adopt.

4 (weeks) + 9 (weeks) = 1 (quarter) why? Because 1 week is 7 days, 13 weeks is exactly 91 days, because the number of days in the month is different, 91 days is exactly 3 months, that is, 1 quarter.

The schedule of gifted students, counterattacking the top students is not a dream!

You can write it in the form of a component, to put it bluntly, it is actually a general division, you can try it, that is, the product of the outer term is equal to the product of the inner term.

An extension of the classic 7-bridge problem, because this is an even number of dots, it is simply impossible to draw in one stroke.

Let's take a look at the diagram below! I'm going to convert your diagram into a little more layman's oxoxo

xoxoxoxoxo

xoxooxoxo

In this way, we can find that if we follow the rules, then we will inevitably encounter X when we come out of O, and we will inevitably encounter O when we come out of X. But after removing the fifth ring in the fourth row (that is, the x), carefully count the number of oxes in the image above

o-13 x-11.

In other words, no matter how you join them, in order to complete the 24 rings, you have to have two o's connected together, or repeated, or some other way that violates the rules. , so there is no solution.

This can be done using the staining method in parity analysis. Paint the adjacent circles one black and one white

If you connect any 2 adjacent circles (not diagonally), these 2 circles must be one black and one white. After all of them are connected, the difference between black and white is at most 1, and here there are 13 black and 11 white, and the difference is 2, so it can't work.

There are 24 squares, including 13 black squares and 11 white squares

Obviously, the black square on the lower right foot is either the last one, or the first one at the beginning is set to the first, then it's --

Black squares can only go to white squares.

The white squares can only go to the black squares.

In this way, there must be 12 black squares and 12 white squares to complete 24 squares, and this picture is 13 black squares and 11 white squares, so it is impossible not to repeat the walk, I hope it can help you

No more requirements?

The S-shaped walk or the return type can be used.

Wang Fu intends to deposit 800 yuan in the bank, and there are two ways to save money: one is to deposit for two years, and the annual interest rate is; Another type of deposit for one year is the annual interest rate of the first year, and then the principal and after-tax interest are combined for another year after the first year matures. The annual interest rate is 5%.

Do the math, which deposit method gets more after-tax interest? How much more?

Trial results. The first is to deposit for two years, and the interest is dollars.

The second type of interest is the dollar.

The latter type of interest is diverse.

There is no pre-tax tax and after tax, and now the interest on personal savings deposits is not subject to personal income tax.

In the image on the left, the folded blank area is a square, and the ratio of the shaded part to the area of the whole figure is 2 7, and the ratio of the shaded part to the area of the square is 2 5. and if they are equal in height, the ratio of the length of the base edge is 2:5, in other words, the ratio of the length to width of the shaded part is 2:

5。In the image on the right, the folded area is again a square, and its area occupies 2 5 of the area of the shaded part. The area of the remaining shaded part is 3 5 of the area of the original shaded part

After thinking about it for a long time, I finally came up with the answer

I can't see it all at all, and I can't help you.

Let's go back to the picture above, and everyone will help you.

Some geniuses just don't show their faces.

Use your brain and imagination to believe that you are all right.

The minus sign is moved to equal to is not equal to Ha.

Let the one above 18 move to the top minus.

Change the equal sign to the less than sign and the equation holds.

I can't help you again, everyone is helping you, and some are geniuses, but they don't show up.
