a dozen

Gọi số vải là x (x > 0)
Ta có: sau khi bán lần đầu thì miếng vải còn lại
\(\left(1-\frac{3}{11}\right)x=\frac{8}{11}x\)
sau khi bán lần 2 thì số vải còn lại là :
\(\frac{8}{11}x-\frac{3}{8}.\frac{8}{11}x=\frac{5}{11}x\)
Theo bài ta có:
\(\frac{5}{11}x\) \(=16\Rightarrow x=35,2m\)

Mỗi mùa 20 - 11 đến các lớp trong trường lại hào hứng, tấp lập chuẩn bị những tiết mục văn nghệ để góp vui trong ngày kỉ niệm nhà giáo việt nam. Năm nay lớp em cũng có một tiết mục diễn kịch. Theo em thì rất đặc sắc và ý nghĩa. Tiết mục diễn kịch "tấm cám" với nội dung được cách điệu: cám là cô gái lười học có đam mê sống ảo trên facebook nhưng lại ghen tỵ với tấm vì cô học giỏi chăm ngoan. Nhưng sự ghen tỵ này cuối cùng cũng được hòa giải bởi cám đã nhận ra được bản thân mình sai lầm nhờ sự giúp đỡ của tấm...

Dear Tom
Thanks for your email about all my friends in New Zealand .My name is Huy. Let me introduce myself and my family. I'm 18 years old this year, a student of Dong Do University. Taking a walk and going out with friends are my hobbies. I am living in Hanoi, but was born and raised in Son La Province. My family has 5 people: my father, mother, older sister, younger sister and me. My father names Tuan, he is 50 years old and he is an engineer. Mymother names Thuan, she's 51 years old, and working as a doctor. My older sister names Thuy, she is 23 years old and she is a singer, she feels happy when singing. Finally, my younger sister, she's 9 years old and studying at Quyet Thang Elementary School. She studies very hard and she is one of the best pupil in her class. On the fine day and with free time, my family often goes out for camping outdoors, it's very meaningful and fun. I feel very happy to be alive in this family. I love my family so much. I will try to learn and work well to take care of my family. I hope that my family is always happy and has the best things. Thank you for listening to my thoughts. Wishing you a happy day

Topic 3 :

At twenty-five past nine, the bell rings and all the students do into the yard. It is time for recess. They are all happy and excited. They meet their friends and have some fun. Many are talking about the last class, or last night's movie. Som are eating and drinking as well as chatting. Some students are playing gameslike blindman's bluff or catch. Some boys are playing marbles and some girls are skipping rope. But the most popular activity is talking. The yard is very noisy until the bell rings. Then everyone goes indoors and classes begin again.

My name is Huy. I am twenty-four years old. I live in Ho Chi Minh city in the south of Vietnam.I’m a generous and easy-going person but when it comes to work I’m a competitive perfectionist. I’m also an optimistic and outgoing person so I have many friends and other social relationships. I enjoy reading, writing and doing math. I decided to become a Civil Engineer because I have always been fascinated by bridges, buildings, and skyscrapers. A degree in Civil Engineering enables me to achieve my goals and also gives me an opportunity to make a difference in the community.

Five years from now, I want to become a project manager of a construction project. As a project manager, my primary goals are managing people, set budgets, and making decisions of all kinds. I also want to speak English fluently so I can work with people from different countries.
