How to calculate? For example, if 100 yuan is deposited in the bank, the interest rate is 3%, the interest will be generated after one year, and the compound interest will be calculated. After 40 years, how much is the total
How to calculate? For example, if 100 yuan is deposited in the bank, the interest rate is 3%, the interest will be generated after one year, and then the principal plus interest will be deposited in the bank, and the interest will be generated; then the principal and interest will be deposited again, and after one year, the principal and interest will be deposited again, and so on, how much money will be generated after 40 years?

Imagination of the earth in a few years

October, early autumn. A desolation of autumn. A group of people gathered in a plain, surrounded by a spaceship. Some people sat on the rocks with newspapers in their hands, thinking, and then tearful. "It's time to go." a leader with a horn said, "please enter the spaceship orderly, and take off in ten minutes." ten minutes later, a

What will the earth be like 100 years from now

One hundred years later, the earth's air is fresh and the environment is beautiful. With the rapid development of high technology, earth shaking changes have taken place in everything on the earth.

Earth composition in 50 years

Travel the earth after 50 years
&#I fell off my chair and hit the back of my head. Then, I felt sleepy
&#I opened my eyes and looked at my watch. WOW! Now it's 2057. I'm on the space shuttle. I can see the scenery of the earth from space. WOW! It's amazing. It seems that it's changed into a new dress. It's not the ball with holes in front of it, but a colorful and dazzling planet
&#I got off the space shuttle and walked leisurely on the streets of the city. Maybe the earth is developing too fast, and I feel very strange to it. The streets are spotless, the trees are full of shade, the birds are singing and the flowers are fragrant, and the fresh air makes people relaxed and happy, A strange thing flew over my head. I had a close look. It turned out that this was the so-called ordinary bicycle. I saw them flying all over the sky, but they were in good order. I couldn't see their shadow under the ground. I wanted to buy a suit of clothes, so I took a taxi and said, "to the clothes and shoes store." when I looked sideways, I was shocked that the driver was a robot! The car started, The robot said: "welcome to take the fully automatic taxi. Please fasten your seat belt. Have a nice trip!..." All of a sudden, the car flew up, this time I don't feel strange. After a while, a big lake appeared in front of me, the car gradually dropped to the ground, and continued to rush forward, I cried in horror: "you are crazy, how..." At this time, the car radio rang: now the smart car has entered the sun lake. Ah! The scenery in front of us is like a beautiful picture: cars, bicycles and other vehicles walking in the water are in good order, kelp, cabbage, seaweed and other underwater plants grow luxuriantly, fish and shrimp and many other aquatic friends play leisurely and freely, and have no fear of human existence, The sun is shining into the water, and it's warm. I have many feelings: People's awareness of environmental protection has really improved. People live in peace with nature, which is so harmonious and wonderful. Thinking about it, the smart car has jumped out of the water and reached its destination
&#I got out of the car and entered a high-tech clothing and shoe store. "Why are people's clothes so strange here? They wear such thick clothes in summer?" I whispered to myself. A salesman came up to me and said, "this is the most common smart clothes. Under the environment of - 100 ℃ to 200 ℃, we can adjust the temperature according to people's needs and make people feel comfortable, It's very safe. It's like walking on the ground. "He pulled me aside to sell. It's amazing!
&#Out of the clothing and shoes store, I wander in this beautiful city. I feel excited, daydreaming and forgetting to return. As I walk, I step on a small stone, slip and become unconscious. When I open my eyes again, I find myself back in 2011, Make the life of the earth family better and better

The earth after 2050

The average of four different integers is 14, the average of three large numbers is 15, and the average of three decimals is 12, if the second large number is odd 4
How much is it?

4 is not an odd number
The smallest 14x4-15x3 = 11
The largest 14x4-12x3 = 20
The sum of the remaining two numbers is 14x4-11-20 = 25
Because the second largest is odd, the smallest is 11 and the largest is 20, the second largest is 13 and the other is 12

There are four different integers. Their average is 13.75. The average of three large numbers is 15. The average of three decimals is 12. The third number is odd. How much is it
Real mathematics paper of a high school affiliated to a University of technology in 2009 (2)

13.75*4-15*3=10
13.75*4-12*3=19
13.75*4-10-19=26
The sum of two integers is 26, which is between 10 and 19,
It can only be 11 + 15, 12 + 14. Because the third number is odd, it can only be 11 + 15
These four numbers are 10, 11, 15, 19

There are four different natural numbers, their average is 14, the average of three large numbers is 15, the average of three decimals is 12, if the second large number is odd
So what's the number

The smallest 14x4-15x3 = 11
The largest 14x4-12x3 = 20
The sum of the remaining two numbers is 14x4-11-20 = 25
Because the second largest is odd, the smallest is 11 and the largest is 20, the second largest is 13 and the other is 12
