Quảng Bềnh (Quảng Bình)

Bánh lọc vốn là món đặc sản xứ Huế, Đông Hà, đến Quảng Bình lại có một phong vị mới lạ, trở thành một trong những món ăn mà du khách không thể không thưởng thức khi đến thành phố biển miền Trung này. Đến Quảng Bình mà không nếm thử món bánh lọc nơi đây thì quả là thiếu đi một phần của chuyến du lịch Quảng Bình. Bánh lọc có bánh lọc lá, bánh lọc trần hay bánh lọc rán tất cả đều rất ngon. Bánh được chấm nước mắm chua ngọt pha rất đúng vị, lại có vị cay cay của ớt xanh và ớt đỏ, vừa đẹp mắt, vừa đậm đà, là hương vị mà du khách không thể nào quên khi nhớ về Quảng Bình.

A robot is a machine. But it is not just any machine. It is a special kind of machine. It is a machine that moves. It follows instructions. The instructions come from a computer.

A robot is a machine. But it is not just any machine. It is a special kind of machine. It is a machine that moves. It follows instructions. The instructions come from a computer. Because it is a machine, it does not make mistakes. And it does not get tired. And it never complains. Unless you tell it to!

Robots are all around us. Some robots are used to make things. For example, robots can help make cars. Some robots are used to explore dangerous places. For example, robots can help explore volcanoes. Some robots are used to clean things. These robots can help vacuum your house. Some robots can even recognize words. They can be used to help answer telephone calls. Some robots look like humans. But most robots do not. Most robots just look like machines.

Long ago, people imagined robots. But nobody was able to make a real robot. The first real robot was made in 1961. It was called Unimate. It was used to help make cars. It looked like a giant arm.

In the future, we will have even more robots. They will do things that we can’t do. Or they will do things that we don’t want to do. Or they will do things that are too dangerous for us. They will help make life better.

9p 20s = 560s

8p 16s = 496s

5p 42s = 342s

tổng tg để đi hết QĐ :  560 + 496 + 342 = 1398 s = 23 p 18s

\(\text{Đặt biểu thức là A:}\)

\(A=\frac{1}{2^2}+\frac{1}{3^2}+\frac{1}{4^2}+...+\frac{1}{99^2}+\frac{1}{100^2}\)

\(\text{Ta có:}\frac{1}{2^2}=\frac{1}{2\times2}< \frac{1}{1\times2}\)

\(\frac{1}{3^2}=\frac{1}{3\times3}< \frac{1}{2\times3}\)

\(\frac{1}{4^2}=\frac{1}{4\times4}< \frac{1}{3\times4}\)

\(...\)

\(\frac{1}{99^2}=\frac{1}{99\times99}< \frac{1}{98\times99}\)

\(\frac{1}{100^2}=\frac{1}{100\times100}=\frac{1}{99\times100}\)

\(\Rightarrow A< \frac{1}{1\times2}+\frac{1}{2\times3}+\frac{1}{3\times4}+...+\frac{1}{98\times99}+\frac{1}{99\times100}\)

\(\Rightarrow A< 1-\frac{1}{2}+\frac{1}{2}-\frac{1}{3}+\frac{1}{3}-\frac{1}{4}+...+\frac{1}{98}-\frac{1}{99}-\frac{1}{100}\)

\(\Rightarrow A< 1-\frac{1}{100}< 1\)

\(\Rightarrow A< 1\left(đpcm\right)\)

vì viết sang bên tay trái nên ta có: 5xxx

Vậy ta có phép tính: (6414-5000):2= 707

vậy số đó là 707

(không biết cách trình bày, thông cảm)

= 3/4 + 5/6 x 3/2 + 1/5

= 3/4 + 5/4 + 1/5

= 15/20 + 25/20 + 4/20

= 44/20

= 11/5

TL

\(\frac{3}{4}+\frac{5}{6}:\frac{2}{3}+\frac{1}{5}\)

\(=\frac{3}{4}+\frac{5}{4}+\frac{1}{5}\)

\(=\frac{11}{5}\)
