Có bao nhiêu số tự nhiên có ba chữ số mà chữ số hàng chục bình phương bằng tổng của các chữ số khác và sự khác biệt giữa số lượng và thứ tự đảo ngược của nó là 495?
Trả lời: Có....số
Tổng của tử số và mẫu số là 91
Tỉ lệ giữa tử số và mẫu số là 2/5
Tử số là (91 : 7 ) x 2 = 26
Mẫu số là (91 : 7 ) x 5 = 65
Hiệu của mẫu số và tử số là 65 - 26 = 39
Đáp số: 39
bao nhiêu số tự nhiên có ba chữ số mà chữ số hàng chục bình phương bằng các sản phẩm của các chữ số khác và sự khác biệt giữa các số và đảo ngược khác của nó là 495?
Are some people born cleaver and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to both these questions is "Yes". To some extent, our intelligence is given at birth, and no amount of special education can make a genius out of child born with low intelligence. On the other hand, a child who lives in a boring surrounding will develop his intelligence less than the one who lives in rich and varied surrounding. Thus the limits of a person's intelligence are fixed at birth but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways. It's easy to show that intelligence is something we are born with if we take two unrelated people at random from the population. It's likely that their degrees of intelligence will be completely different. If, on the other hand, we take children - identical twins, they will very likely be as intelligent as other. This clearly suggests that intelligence depends on birth.
Read the following passage and do the tasks below :
Most of us think that great ideas were the result of genius thinking. However, many of the greatest discoveries and inventions in history began with very simple beginnings.
In the 18th century, James Watt was boiling water at home. As the water began to boil, he suddenly noticed that the steam was pushing the lid of the kettle. From this, he created the steam engine.
In ancient Greece time, Archimedes stepped into a bath tub and felt that water was being pushed out when he stepped in. This is how he came up with the idea of how to find the purity of gold.
In the 17th century, Isaac Newton was sitting under a tree when an apple fell and hit him on the head. This is when he realized the pulling force of the earth - the gravity.
There are many other examples of how great ideas began with simple beginnings. What one needs to become an inventor are careful observation and a lot of hard work.
Answer the questions:
1. What did James Watt create?
-> He created the steam engine.
2. Did Isaac Newton realize the pulling force of the earth?
-> Yes, he did.
3. How many inventors are mentioned in the passage?
-> Three inventors.
