Question

7 в районной библиотеке к новому учебному году открыли читальный зал. В нём поставили 8 четырёхместных столов. Это в 2 раза меньше, чем двухместных, и на 3 больше, чем шестиместных. Сколько человек одновременно могут заниматься в этом зале? кекккешки ​

Answer 1

1) 8*2=16 (двухместных cт.)

2) 8-3=5 (шестиместных ст.)

Итого:  8 четырехместных, 16 двухместных, 5 шестиместных

3) 8*4+16*2+5*6=94 (чел. всего)

Ответ: 94 человека одновременно могут заниматься в этом зале.

Объяснение: (ст. - столов), (чел. - человек).

Answer 2

Calculation of the Number of People in the Reading Room

To determine the number of people who can simultaneously use the reading room, we need to analyze the given information.

According to the information provided, the reading room in the local library has 8 four-seater tables. It is mentioned that this number is twice as small as the number of two-seater tables and three times larger than the number of six-seater tables.

Let's assign variables to represent the number of two-seater and six-seater tables: - Let x be the number of two-seater tables. - Let y be the number of six-seater tables.

Based on the given information, we can set up the following equations:

1. The number of four-seater tables is 8: - 8 = 8 (four-seater tables)

2. The number of four-seater tables is twice as small as the number of two-seater tables: - 8 = 2x (two-seater tables)

3. The number of four-seater tables is three times larger than the number of six-seater tables: - 8 = 3y (six-seater tables)

To find the values of x and y, we can solve the system of equations.

Solving the System of Equations

Let's solve the system of equations to find the values of x and y.

From equation 2, we have: 8 = 2x

Simplifying equation 2, we get: x = 4

From equation 3, we have: 8 = 3y

Simplifying equation 3, we get: y = 2

Therefore, the number of two-seater tables (x) is 4, and the number of six-seater tables (y) is 2.

Calculating the Total Number of People

To calculate the total number of people who can simultaneously use the reading room, we need to consider the seating capacity of each table.

Given: - Four-seater tables: 8 - Two-seater tables: 4 - Six-seater tables: 2

Let's calculate the total number of people:

- Four-seater tables: 8 tables * 4 seats per table = 32 people - Two-seater tables: 4 tables * 2 seats per table = 8 people - Six-seater tables: 2 tables * 6 seats per table = 12 people

Therefore, the total number of people who can simultaneously use the reading room is: 32 (four-seater tables) + 8 (two-seater tables) + 12 (six-seater tables) = 52 people.

So, in the newly opened reading room in the local library, up to 52 people can study simultaneously.
