② Solve the equation (1/4-1/5) ÷ x =10.

Solution: (1/4-1/5) =10x.

( 1/4- 1/5)/ 10 = x

x= 1/200

(3) Master Zhang processes a batch of parts. Originally planned to process 800 pieces a day, it took 10 days to complete. In fact, the daily processing time is a quarter more than originally planned. Actually, it will take a few days to finish.

Three-step calculation: 800x 10=8000 (pieces)

800x (1+1/4) =1000 (pieces)

8000/ 1000=8 (days)

Two-step calculation: 800x 10=8000 (pieces)

8000/(800x5/4)=8 (days)

A: Actually, it will be completed in eight days.

It takes four days for Team A and Team B to repair a section of road together. If it takes 10 days for Team A to complete it alone, it is known that Team B will repair 33 meters every day. How long is this road?

Solution: Set the armor to repair X meters every day.

(x+33)x4= 10x

4x+ 132= 10x

-6x=- 132

x=22

22x10 = 220m

This road is 220 meters long.

⑤ Two teams built a canal. Team A needs 5 days to build alone, team B needs 7 days to complete it alone, and it takes 2 days for the two teams to build 240 meters together. How many meters do Team A and Team B repair every day?

Solution: Let this canal be x meters long.

(x/5+x/7)x2=240

24/35x=240

x=350

350/5=70 meters 350/7=50 meters

A: Team A repairs 70 meters every day and Team B repairs 50 meters every day.

Nurse professional qualification certificate, related issues, what certificate is urgently needed? Nurses can only get one certificate when they pass the exam, which is called nurse qualification certificate (health professional and technical qualification certificate). This certificate has nothing to do with registration, but is used by the unit to hire professional titles and test nurses in the future. . . This certificate was issued late, because it was not made by the Ministry of Health but by Ministry of Human Resources and Social Security, and it took a long time to process. But this card has nothing to do with nurse registration, so it doesn't matter much later.

In fact, you should hurry to get a certificate (a piece of A4-sized paper), which is called the Certificate of Qualification Examination for Nurses, because starting from 20 1 1, the registration management department will only issue the nurse's practice certificate after registration, and this certificate should be issued during this period. However, even if you get this certificate, you do require a work unit when you register. . .

So if you haven't received this certificate, you really have to worry, unless the local health registration administration temporarily allows you to register with transcripts (if you strictly follow the regulations after 20 1 1 year: candidates after 20 1 1 year are no longer allowed to use transcripts. Only candidates before 20 1 1 can register with their transcripts. If you really haven't received this certificate, and your local health management department wants to register with a qualified certificate, then you will have to wait until this certificate is issued. This certificate is made and issued by the health talent exchange center and should be notified by the local health center department. If the application is centralized by the school, the school should collect it on its behalf and then inform everyone.

Some steps can be omitted, depending on your ability.

All big factories, whether it is the first flashlight or the new flashlight, the first one is polished by hand.

It is not difficult to build a good flashlight. Raw materials are easy to find, the electronic parts market is everywhere, and the price is not high. The main thing is whether we can find processing equipment (processing spools matching the required number of batteries). There is also a little basic knowledge of circuits and circuit calculations.

Writing on the topic of warmth is urgent! The sooner the better, the warm memories of childhood are like a cup of strong coffee, warm to your heart, and childhood is like a cup of light tea, which makes you memorable; Childhood is like a rainbow of storms; Colorful and dazzling; Childhood is like the afterglow of the sunset, so unforgettable; Just like that winding path, it makes you grow. The wind can't blow away this warm memory; Rain is falling all can't hide this moving melody. Only lovely sunshine can shine on it and preserve it ... Recall the humble childhood events. Although the events are small, those memories are so touching. Because of these memories, you can make continuous progress and pursue, and you can grow up. Childhood always reminds people. Think back to that colorful dream, when Yaya was learning a language, when she just learned to walk, when she first stepped on the stage, when she called her parents for the first time, at that moment, all the shots came into your eyes. It was an unforgettable memory, an unforgettable childhood. On the day when I first took up my new schoolbag and went to school, I was finally able to go to school like other children. For me, this is my historic moment. My parents photographed this most happy and unforgettable appearance with a camera, which became the most gratifying thing for my parents. It has also become the happiest portrayal of my family. This unforgettable moment, so beautiful and sweet, has always appeared in my mind. However, beauty is only the past. In the long days, after repeated tempering, I honed myself as hard and weak as steel. No one will know the pressure of study, and no one will be pitiful. In the autumn when the leaves are falling, there is only hardship and only lost happiness. This is bitter. When I was a child, in the spring when a hundred flowers blossom, my childhood with beautiful dreams passed quickly. So far, I will not shed tears in the face of the cruelty of reality, and my tears will be covered by that dark cloud. Childhood tears are so weak and stingy. Childhood dreams are colorful, as beautiful as a hundred flowers, unforgettable and unforgettable. At that time, there was no worry or worry. Childhood dreams are like the night sky, so broad and quiet. Childhood dreams are like countless stars. They only blink, can't talk, honest and calm ... countless stars, like countless dreams, flooded into my little head. Since then, I have been thinking about countless problems. Growing up under the blue sky, dreams in the night sky are like small castles piled up on the beach and dreams by the blue sea; My son always likes to play under the banyan tree, and he also likes to sit there quietly and listen to the old story. At that time, the dream was green. When I was a child, I always liked to sit in front of my hometown and enjoy the golden leaves flying all over the sky in the autumn when the leaves were falling. At that time, my dream was golden. I always liked dreaming when I was a child. You can't find the exit maze if you walk in your dream. Being locked in the maze again and again, I feel so confused. In real life, when my fighting spirit was aroused, the dream was the color of fire ... Memories made everything in the world quiet, relaxed and warm, reminded you of distant but not distant dreams, reminded you of the rain, which was a beating melody. When you fall, there is a force watching you, reminding you to fly the paper plane under the blue sky and the dream you expect. The clock can only go forward, not backward. Childhood only has aftertaste and memories. Everyone in ........................................................................................................................................................................... has his colorful childhood. Childhood is the most precious thing in life. This is the beginning of your life. If you have it, you have a lifetime. We should cherish it. Dreams often change. Dreams are the goal that people pursue all their lives. Only struggle, struggle, dreams can be realized, and that will become a reality. ... only by remembering everything will you feel good ...
