Question

Определи количество досок для постройки причала.Если 10 досок положить по длине друг за другом, то общая длина окажется равна половине длины причала. Ширина причала в 6 раз больше ширины одной доски. Запиши число в ответе.

Answer 1

10 досок-половина длины причала

1) 10 * 2 = 20(дос).-длина причала

Ширина причала равна ширине 6 досок,значит, по ширине надо уложить 6 рядов

по 10 досок:

2) 20 * 6 = 120 (дос).

Ответ: 120досок.

 

 

Answer 2

Calculation of the Number of Boards for the Dock

To determine the number of boards required for the construction of the dock, we need to consider the given information:

- If 10 boards are placed end to end, their total length will be equal to half the length of the dock. - The width of the dock is 6 times greater than the width of one board.

Let's break down the problem and find the solution step by step.

1. Let's assume the length of one board is x units. 2. If 10 boards are placed end to end, their total length will be 10x units. 3. According to the given information, the total length of the 10 boards is equal to half the length of the dock. Therefore, we can write the equation: 10x = (1/2)L, where L represents the length of the dock. 4. The width of the dock is 6 times greater than the width of one board. So, the width of the dock can be represented as 6x units.

Now, let's solve the equation to find the value of x and then calculate the number of boards required.

Equation: 10x = (1/2)L

To solve for x, we can rearrange the equation as follows:

x = (1/20)L

Now, we know that the width of the dock is 6 times greater than the width of one board, so the width of the dock is 6x units.

Width of the dock = 6x = 6 * (1/20)L = (3/10)L

Therefore, the width of the dock is equal to (3/10)L units.

To find the number of boards required, we need to divide the length of the dock by the length of one board:

Number of boards = L / x = L / ((1/20)L) = 20

So, the number of boards required for the construction of the dock is 20.

Please note that the above calculation is based on the given information and assumptions made. If there are any additional constraints or specifications, the calculation may vary.
