The examination paper in informatics and ICT consists of two parts. There are 23 tasks in the first part. All of them require a short answer: in task No. 2 - a string of characters, in other tasks - an unsigned integer. Checking the answers to the tasks of part 1 is carried out automatically: the examiner's answer is compared with the reference answer.
The tasks in the variant are arranged in increasing complexity, so it is recommended to complete them in a row, one after the other. If you find it difficult, you can skip the task and return to it after completing all the tasks that you managed to solve at once.
Approximately 90 minutes are allotted to complete the first part of the exam. Under the conditions of a real exam, which lasts 3 hours 55 minutes, you can spend more time on solving Part 1 tasks, but it should be understood that in this case there may not be time left to solve Part 2 tasks. USE options it is recommended to allocate a double lesson for solving the tasks of part 1, that is, 90 minutes of pure time.

The purpose of the manual is to provide readers with information about the structure and content of control measuring materials in mathematics, the degree of difficulty of tasks. The collection contains answers to all variants of tests. In addition, examples of forms used in the exam for recording answers and decisions are given. The manual can be used by teachers to prepare students for the exam in mathematics in the form of the Unified State Examination, as well as by high school students for self-training and self-control.

Textbook example

The examination paper includes 20 tasks.
3 hours (180 minutes) are allotted to complete the work.
Answers to tasks are written according to the samples below in the form of a number or a sequence of numbers. First, write down the answers to the tasks in the answer field in the text of the work, and then transfer them to the answer form No. 1 to the right of the number of the corresponding task.
If the answer is a sequence of numbers, as in the example below, then write this sequence in the answer sheet No. 1 without spaces, commas and other additional characters.
All USE forms are filled in with bright black ink. It is allowed to use gel, or capillary, or fountain pens.
When completing assignments, you can use a draft. Draft entries do not count towards the assessment of the work.
The points you get for completed tasks are summed up. Try to complete as many tasks as possible and score the most points.

Examples.
If you mix a 54% acid solution and a 61% solution of the same acid and add 10 kg of pure water, you get a 46% acid solution. If, instead of 10 kg of water, 10 kg of a 50% solution of the same acid were added, then a 56% acid solution would be obtained. How many kilograms of a 54% solution were used to make the mixture?

On January 15, it is planned to take a bank loan for 7 months. The conditions for its return are as follows:
- On the 1st day of each month, the debt increases by 4% compared to the end of the previous month;
- from the 2nd to the 14th day of each month, part of the debt must be paid;
- On the 15th day of each month, the debt must be the same amount less than the debt on the 15th day of the previous month.
What percentage of the loan amount is the total: the amount of money that needs to be paid to the bank for the entire loan period?
