Question

Ломанная состоит из 3 звеньев длинна первого звена 8 см,а второго звена в 4 раза меньше первого,третье звено в 3 раза больше чем второго Найти длинну ломанной

Answer 1

8:4=2см- 2 звено 2х3=6см- 3 звено 8+2+6=16см

Answer 2

Calculation of the Length of the Broken Line

To find the length of the broken line, we need to calculate the sum of the lengths of its three segments. Let's denote the length of the first segment as x.

According to the given information: - The length of the second segment is 4 times smaller than the length of the first segment. - The length of the third segment is 3 times larger than the length of the second segment.

Let's calculate the lengths of the second and third segments in terms of x:

- Length of the second segment: 4 * x - Length of the third segment: 3 * (4 * x) = 12 * x

Now, we can calculate the total length of the broken line by summing up the lengths of the three segments:

Total length = x + 4x + 12x = 17x

Therefore, the length of the broken line is 17 times the length of the first segment.

Calculation Example

Let's assume the length of the first segment is 8 cm. Using this value, we can calculate the length of the broken line:

Total length = 17 * 8 = 136 cm

So, if the length of the first segment is 8 cm, the length of the broken line will be 136 cm.

Conclusion

In conclusion, the length of the broken line is 17 times the length of the first segment. The specific length of the broken line depends on the length of the first segment, which in this case is 8 cm.
