Work instructions
Job characteristics. In total, there are 20 tasks of a basic level of complexity and 3 tasks of an increased level of complexity for schools with in-depth study of mathematics. The work consists of five plots: plots 1-4 are mandatory, plot 5 is performed only by students in classes with in-depth study of mathematics.
Councils and instructions for the performance of work. We advise you to start with the plot, the tasks of which cause you less difficulty, then move on to other plots. To save time, skip the task that you can't complete right away and move on to the next one. If you have time left, you can return to the missed tasks.
The answer to tasks (B1-B20) must be an integer or a final decimal fraction. The answer should be written in the answer sheet AB to the right of the number of the task you are performing, starting from the first cell.
When correcting an incorrect answer in tasks B1-B20, cross out the old answer and write the new one on the right without spaces.
When completing the tasks of plot 5 (C1-C3), it is necessary to write down a reasoned decision and answer in the answer sheet C. The text of the task should not be rewritten in the form, you only need to indicate its number.
The control and measuring materials issued to you can be used as drafts. Please note that entries in the draft will not be taken into account when evaluating the work.
The use of a calculator is not allowed.
We wish you success!

(2) But it was not the famous Mukhtar, who was filmed in the film "Come to me, Mukhtar!". (3) That Mukhtar was a thoroughbred shepherd and helped to look for criminals. (4) And when he was wounded and he could no longer work, people continued to feed him and take care of him. (5) And this dog, which I want to tell you about, was a simple mongrel. (6) But she honestly served her masters: she guarded the garden, played with the children and was ready to rush at anyone who would dare to offend them. (7) But the people with whom she lived were not at all worth her devotion. (8) When the cold came, they left her in the country and left for the city. (9) At first, the hungry, emaciated dog was waiting for its owners. (10) Then she went to look for them. (11) How could the dog know that the owners no longer need it ... (12) At first, she ran along a country road. (13) Noticing a person from afar, she stopped, peered carefully, then caught up and sniffed. (14) But these were all strangers, and she again ran on. (15) The road took her to the highway, and she kept running and running aimlessly ... (16) On Sunday, my husband and I, as always, arrived at the dacha. (17) While Shura poured seeds into the bird feeder and hung them for tits fat, I went to the house. (18) At the porch, all shrinking, dirty and so thin that you could count all the ribs, the dog lay and looked at me in fear. (19) Mukhtar stayed with us. (20) He recovered a long time ago, but he was not going to leave us, although he could do it freely, because there were a lot of broken boards in our fence. (21) Mukhtar turned out to be a smart and quick-witted dog. (22) Soon he not only knew all the people living nearby, but willingly met them at the bus stop and escorted them along our lane. (23) Now we were no longer worried, if for some reason not could bring the dog food. (24) Mukhtar was always full. (25) He no longer ate oatmeal soup, but chose bones and pieces of meat from it. (26) And why does he need soup! (27) It used to happen that you would come, and empty packages, scraps of newspapers, papers were lying near the gate. (28) From them I could always tell which of his friends had been here. (29) Here is a sheet from a notebook - it was Katya who shared breakfast with him, here is a newspaper - it means Kolya came. (30) He collected food for Mukhtar from the whole two-story house, and his friend - Seryozha Gavrilov - brought treats from Moscow. (31 ) Mukhtar also made friends among adults. (32) And among them is our neighbor Fedor Vasilyevich. (33) He lived opposite us, often came to us and, if for some reason we could not come, fed Mukhtar. (34) Mukhtar knew him well and loved him. (35) - Let him live with me, - Fyodor Vasilievich suggested. (36) - We have a new fence, just put up, otherwise it’s true, no matter how dog lovers catch it. (37) And here Mukhtar lives with a new owner. (38) There he has a good new kennel, they feed him well and, most importantly, they love him. (39) Everyone loves him: Fedor Vasilyevich himself, and his wife, and little granddaughter Andryusha. (40) Mukhtar also loves his new owners. (41) He carefully guards their peace, guards their garden, but still does not forget us, and when he is released, he always comes to visit. (42) And on short winter days, Mukhtar, as before, meets his friends and escorts them home through our dark alley. A1.
