Question

ломаная состоит из трех звеньев Длина одного звена 4 сантиметра второе звено в 5 раза длиннее первого а третье на 8 сантиметра короче второго Найди длину всей ломаной Во сколько раз 1 звено ломаной короче 3 помогите плиз

Answer 1

1. 4Х5=20 см (длина 2 звена)
2. 20-8-12 см (длина 3 звена)
3. 4+20+12-36 см (длина всей ломанной)
4. 12:4=3 (в три раза 1 звено меньше 3)

Answer 2

Длина всей ломаной- 36 см
первое звено в 3 раза короче третьего.

Answer 3

Problem Analysis

We are given a broken line consisting of three links. The length of the first link is 4 centimeters. The second link is 5 times longer than the first link, and the third link is 8 centimeters shorter than the second link. We need to find the length of the entire broken line and determine how many times the first link is shorter than the third link.

Solution

To find the length of the entire broken line, we need to add the lengths of all three links.

Let's calculate the length of the second link: - The second link is 5 times longer than the first link, so its length is 5 * 4 = 20 centimeters.

Now, let's calculate the length of the third link: - The third link is 8 centimeters shorter than the second link, so its length is 20 - 8 = 12 centimeters.

Finally, let's calculate the length of the entire broken line: - The length of the entire broken line is the sum of the lengths of all three links: 4 + 20 + 12 = 36 centimeters.

To find how many times the first link is shorter than the third link, we can divide the length of the third link by the length of the first link: - The first link is 4 centimeters long, and the third link is 12 centimeters long. - Therefore, the first link is 3 times shorter than the third link.

Answer

The length of the entire broken line is 36 centimeters. The first link is 3 times shorter than the third link.
