Question

Известно, что средний гражданин Германии расходует 26 кг стирального порошка в год. По-видимому, Германия — самая стирающая страна в мире. Определите, сколько потребуется литров воды на одного такого гражданина, если стиральная ма­шина требует на одну стирку 100 литров воды и 250 г порошка? Сколько грязи прибавится на Земле от стирки белья такого гражданина, если процент ее от веса белья составляет 10%, а в машину при каждой стирке загружается 4 кг белья? Рассчитайте, сколько килограммов белья стирают в вашей семье, исходя из веса стиральных порошков, потребляемых у вас для стирки: за месяц, за год. Вычислите, сколько при этом сли­вается грязи, при загрязненности белья 10%?

Answer 1

100л-250г
x л-26000г
x= 100*26000:250=10400
Ответ:1049 литров в год

Answer 2

According to the information provided, the average citizen of Germany consumes 26 kg of laundry detergent per year. To determine the amount of water required per person, we need to know the water consumption per wash cycle and the number of wash cycles per year.

If one wash cycle requires 100 liters of water and 250 grams of detergent, we can calculate the water consumption per person as follows:

Water consumption per person = (26 kg detergent) x (1000 g/kg) / (250 g detergent) x (100 liters water) = 1040 liters water per person per year [[1]].

Next, let's calculate the amount of dirt added to the Earth from the laundry of one citizen. If the dirt accounts for 10% of the weight of the laundry and each wash cycle loads 4 kg of laundry, we can calculate the amount of dirt added per wash cycle as follows:

Dirt added per wash cycle = 4 kg laundry x 10% = 0.4 kg dirt per wash cycle.

To determine the total amount of dirt added per person per year, we need to know the number of wash cycles per year. Without this information, we cannot provide an exact calculation.

Moving on to the calculation for your family's laundry. If you provide the weight of laundry detergent consumed for washing in a month and a year, we can calculate the weight of laundry washed in your family. Additionally, if you provide the percentage of dirt in the laundry and the number of wash cycles per month or year, we can calculate the amount of dirt discharged.

Please provide the weight of laundry detergent consumed for washing in a month and a year, as well as the percentage of dirt in the laundry and the number of wash cycles per month or year, so that we can assist you further with the calculations.
