Angel Statue Introduction.

Claudia is tired of the life of the family, and she has to wash the dishes, clean the garbage can, ...... every dayShe wanted to do something unexpected, so she orchestrated a "run away from home". Her chosen place was the Metropolitan Museum of Art in New York, and her companion was her "rich" and petty brother, Jamie. In the heavily guarded Metropolitan Museum, the two of them magically spent a week!

In the meantime, a statue of a cherub suspected to have been carved by Michelangelo is on display in the museum. Claudia was immediately intrigued by the statue, and she was determined to find out who had created it. But right now, they don't have the slightest clue, and they're running out of money......Claudia was not willing to go home in such a "mediocre" way, and she and her brother used the last bit of money to finally find the statue's original owner, Mrs. Frankweil.

At this point, can the truth be revealed? The book won the 1968 Newbery Prize for Children's Literature Gold.

Divide the coins into 2 groups of 4 each, the left is x1-4, the right is y1-4, and the remaining one is z. For the first time, if you put a group on each side of the scale, there will be 3 situations: left and right balance (left and right can be interchanged, so we will discuss them in 2 cases below).

Scenario 1 is balanced: Z=500 is obtained, and 400 and 600 coins are in the same group. After 3 times, each group takes one and weighs it each time, and the results can be obtained.

Situation 2: Left weight: Left weight is divided into 3 cases: and 400 is on the right; and 600 on the left; and 600 on the left;

The second time each group takes out one and then weighs, if the balance is balanced, it will be taken and z symmetrical, and the result can be obtained; If it is still left-weighted, the two sides are swapped for the third time, and then one of the swaps is weighed for the fourth time with z, and the result can be obtained. The right weight is the same as the left.

Divide the coins into 3 groups (A1, A2, A3) (B1, B2, B3) (C1, C2, C3).

Take A1, A2, A3 and B1, B2, B3 (1 time).

If balanced, then 2 counterfeits must exist in a group at the same time, and each group will take 2 scales (3 times in total) to distinguish the light and heavy counterfeits - a total of exactly 4 times.

If there is no equilibrium, assuming that A1, A2, and A3 are heavier than B1, B2, and B3, there are three possibilities:

First, the heavy counterfeit coins are in A1, A2, A3, and the light counterfeit coins are in B1, B2, B3, C1, C2, and C3.

Second, the heavy counterfeit coins are in A1, A2, and A3, and the light counterfeit coins are in C1, C2, C3, B1, B2, and B3.

Thirdly, heavy counterfeit coins are in C1, C2, and C3, and light counterfeit coins are in B1, B2, B3, and A1, A2, and A3.

In either case, take 2 scales from each group (3 times in total) to distinguish the light and heavy counterfeits - a total of exactly 4 times.

1.The relationship between the Viennese people and the Vienna Woods is one of mutual benefit and harmony. The Vienna Woods provide the Viennese with a beautiful natural environment, which starts with the first.

As can be seen in paragraphs 1 and 3; The Viennese, on the other hand, are committed to protecting the forest and making it a perfect evolution.

2.The end is the finishing touch to the text, reminding us of the importance of living in harmony with nature. The whole text is devoted to the beauty of the Vienna Forest and the fact that the Viennese people are proud of it, and at the end it is clearly structured that the viewpoint of protecting the natural environment is revealed.

3.Reading this article, I couldn't help but marvel at the beauty of the Vienna Woods and at the same time express a deep admiration for the love of nature by the Viennese people. On the other hand, we live in modern society, it is not very rare for cars to flow like a dragon, but a series of modern industries such as automobile exhaust and chemical factories are eroding the heart of nature all the time, and the city is becoming more and more modern, and the natural green is gradually disappearing from our eyes, is this what we want to see?

After reading this article, I envy the Viennese people, they can have such a beautiful forest, but I also know that they have worked hard for generations, and their love for nature has been exchanged for this green soil, just imagine if each of us can love nature as much as the Viennese, then can't we also have the same forest?

1 "Reciprocity and mutual dependence".

2. The harmonious and intimate relationship between nature and human beings.

3 As a Chinese, while envious of Vienna, I am deeply anxious about the current situation in our country, because China's forest area is only about 13 of the country's land, increasing desertification land, and many scenic spots are frequently "urgent" due to serious pollution.

In the face of this situation, we should start from me, consciously protect the environment, and establish a strong sense of environmental protection.

You set the total to x

The number of processed units in the first week is 2x 7 (two-sevenths multiplied by x), and the number of processed units in the second week is 3x 8 (three-eighths multiplied by x), and the equation 2x 7+3x 8+38=x is obtained, and the solution of this equation yields x=112, so the number of parts in this batch is 112.

【I've grown up】 Thinking back to the time I spent with my classmates day and night, the bits and pieces of my study and life, not only are your requirements not very clear, go to the best article network to see it There are many such essays in elementary school and middle school.

Solution: (1) Set up x medium-sized book corners, then form small book corners for (30-x) From the title, 80x+30(30-x) 1900 50x+60(30-x) 1620, solve this inequality group, get 18 x 20 Since x can only take an integer, the value of x is 18,19,20 When x=18, 30-x=12;When x=19, 30-x=11;When x=20, 30-x=10 Therefore, there are three schemes: scheme 1, 18 medium-sized book corners and 12 small book corners; Plan 2: 19 medium-sized book corners and 11 small book corners; Option 3: 20 medium-sized book corners and 10 small book corners (2) The cost of option 1 is:

860 18 + 570 12 = 22320 (yuan); The cost of option 2 is: 860 19 + 570 11 = 22610 (yuan); The cost of plan 3 is: 860 20 + 570 10 = 22900 (yuan) Therefore, the cost of plan 1 is the lowest, and the minimum cost is 22320 yuan.

After X years, it is 5 times.

then 38+x 5 (2+x).

x 7, that is, after 7 years, the father's age is 5 times higher than that of the female Qi Qi Mou this envy.

（1）2a-1=3

a=23a+b-1=4*4*4=64

The value of a is substituted to obtain b=59

a+2b=2+2*59=120

2）a=-1/2，b=-1，c=1/2

2a-7b+2c=9

3）x^2=1,∴x=1,y=1

4)a=1,b=2

The original is formed into 1+1 (2*3)+1 (3*4)+1/（2011*2012）

1 2a-1=3 a=2 4^3=64 3a+b-1=64 b=59 a+2b=120

2 2a+1 is squared greater than or equal to o and the same is true after 2a+1=0 b+1=0 2c-1=0 and then a=,b=-1,c=
