Question

Ребят,плиз помогите решить задачку,чет туплю и никак не соображу че тут надо делать Производительность двух колбасных цехов относится как 5:7. За 6 часов совместной работы они производят 1800 килограммов продукции.Сколько килограммов продукции изготовит второй цех за четыре часа самостоятельной работы?

Answer 1

Сначала нужно узнать сколько килограммов продукции оба цеха изготавливает за час: 1800/6=300. 300 - это 12 частей (7+5). Найдем одну часть: 300/12=25. Далее 25 умножим на 7 (чтобы узнать сколько изготавливает второй цех за один час), 25*7=175. Далее 175 умножим на 4, 175*4= 700 килограммов.

Answer 2

Problem Analysis

To solve this problem, we need to determine the productivity ratio between two sausage factories and then use that ratio to find the amount of production the second factory can produce in four hours of independent work.

Solution

Let's assume that the productivity ratio between the two sausage factories is 5:7. This means that for every 5 units of production from the first factory, the second factory produces 7 units.

We are given that in 6 hours of joint work, the two factories produce 1800 kilograms of product. To find the amount of production the second factory can produce in four hours of independent work, we can follow these steps:

1. Calculate the total productivity of both factories in 6 hours of joint work. 2. Use the productivity ratio to determine the amount of production from the second factory. 3. Calculate the amount of production from the second factory in four hours of independent work.

Let's calculate the solution step by step:

1. Calculate the total productivity of both factories in 6 hours of joint work: - Let's assume the productivity of the first factory in 6 hours is x kilograms. - The productivity of the second factory in 6 hours would be (1800 - x) kilograms, as the total production is 1800 kilograms. - Since the productivity ratio is 5:7, we can set up the equation: x / (1800 - x) = 5 / 7. - Cross-multiplying, we get 7x = 5(1800 - x). - Simplifying, we have 7x = 9000 - 5x. - Combining like terms, we get 12x = 9000. - Dividing both sides by 12, we find x = 750.

2. Use the productivity ratio to determine the amount of production from the second factory: - The productivity of the second factory in 6 hours would be (1800 - x) kilograms. - Substituting the value of x, we find the productivity of the second factory is 1800 - 750 = 1050 kilograms.

3. Calculate the amount of production from the second factory in four hours of independent work: - Since the productivity ratio remains the same, we can set up the equation: 6 / 4 = 1050 / y, where y represents the amount of production from the second factory in four hours. - Cross-multiplying, we get 6y = 4 * 1050. - Simplifying, we have 6y = 4200. - Dividing both sides by 6, we find y = 700.

Therefore, the second factory will produce 700 kilograms of product in four hours of independent work.

Answer

The second sausage factory will produce 700 kilograms of product in four hours of independent work.
