I most of animals as long as they are not harmful or dangerous, but my favorite one is dog. Dogs are well known for their intelligence and loyalty; and in my opinion, their looks are also very cute. There are many different breeds in the world, and most countries have at least one featuring dog breed of their own. Nowadays, most breeds of dog are not the same as they were from hundred years ago, but they have been artificially selected for parular appearances and behaviors by people for specific purposes. Because of this selective breeding, dogs have developed into hundreds of varied breeds, and they show more connection with people than any other land mammal. Some of the most popular breeds are Golden Retriever, Siberian Husky, Alaska, Bulldog, Doberman, German Shepherd, and it can be said that each breed has their own significant function in human’s life. Dogs have been the best companions for human at a very early age, their roles in hunting, herding, pulling loads and protection truly helped human in a lot of aspects. More recently, they have developed more pracal roles in assisting police and military, companionship, and helping handicapped ones, and most people accept that dogs appear in their lives more than they had ever thought. My family has a little dog, and he has all of the best qualities of a good one. He is actually my best friend since I am the one who spends most time playing with him. I love him very much, but I have to accept a fact that his life span is much shorter than human. A well – treated dog can live up to 12 or 15 years, and each year in dog’s life span is equal with 5 years in human’s one. Since dogs are the most popular animal to show such love and loyalty to human, its shortage in life span is truly a sad thing for all the dog lovers. Although I do not have much time with my beloved dogs, I always love them as my best companions in life.

Rosy is a dog which I have been keeping for the past four years. It was by sheer accident that Rosy came into my hands. Our neighbour Mr. Jones was a dog lover. He has a good kennel in his house where he reared different types of dogs. Suddenly,he decided to leave the town and he wanted to dispose some of the dogs. I told my father that I wanted a pet and my father agreed. That was how Rosy came into my possession.

Why was it named Rosy ? I cannot say. It is an Alsatian. It is of medium height, grey in color with dark spots near her belly, bushy and glistening eyes. It grew into a beautiful and magnificent dog much to the envy of others.

Rosy takes pleasure in sniffing about the comers when she has nothing parular to do. She is as docile as a deer in our presence. When we are not at home she will be at her mettle and no one can easily come near our gate or house. Though she does not bite, she will bounce on the person baring her teeth so much so that she can paralyse any intruder. She recognizes the postman as a friend and so does not do him any harm.

I give her some biscuits and milk in the morning, rice and curry in the afternoon. Usually she is not given any food in the night. When we are at our table, Rosy keeps company with me but she shows no eagerness to touch even a crumb unless offered. Whenever I go out in the evening, she accompanies me. Rosy seems to be one of my friends, I love her very much.

mình làm hơi khó hiểu tí ha, bạn có thể tham khảo cách của mình nha!

S là quãng đường , T là thời gian nha

gọi f là địa điểm nam đi bộ đến khi minh chở phú đến c

gọi k là địa điểm phú đi bộ đến khi minh từ c đến d đón nam

S_af là: 2.5=10km

S_ac là: 20.2=40km

S_fc là: 40-10=30km

mặt khác ta có: S_fc=t₁.(20+5) mà S_fc=30km suy ra t₁.25=30 suy ra t₁=1,2

S_ck=1,2.4=4,8km

S_dc=1,2.20=24km

S_dk=4,8+24=28,8km

thời gian phú đi trên quãng đường kb là: 28,8:(20-4)=1,8

S_kb là: 4.1,8=7,2km

khoảng cách ab là: 7,2+40+4,8=52km

mình làm hơi khó hiểu chút nha, sorry

1/7+1/8+1/56

=15/56+1/56

=\(\frac{4}{14}\)

\(\frac{1}{7}+\frac{1}{8}+\frac{1}{56}\)

= \(\frac{1.8}{7.8}+\frac{1.7}{8.7}+\frac{1}{56}\)

= \(\frac{8}{56}+\frac{7}{56}+\frac{1}{56}\)

= \(\frac{16}{56}=\frac{2}{7}\)

Theo đề , ta có 

\(\frac{140-x}{260-x}=\frac{1}{4}\)   

\(\left(140-x\right)\cdot4=1\cdot\left(260-x\right)\)   

560 - 4x = 260 - x 

560 - 260 = 4x - x 

300 = 3x 

x = 300 : 3 

x = 100
