Question

Небольшой хвойный лес за один год отфильтровывает 35 т пыли,что составляет 50% пыли, отфильтрованной таким же по размеру березовым лесом. Сколько тонн пыли отфильтровывает за год небольшой березовый лес? Срочно. С кратким условием

Answer 1

Ответ:

Пропорция

35 т - 50%

x т - 100%

x = 35*100:50 = 70 т

Answer 2

Ответ: 70 т.

Пошаговое объяснение: 35 : 50 * 100 = 70(т)

Answer 3

Calculation of Dust Filtered by a Small Birch Forest

To calculate the amount of dust filtered by a small birch forest in one year, we need to use the information provided. According to the given information, a small coniferous forest filters 35 tons of dust in one year, which represents 50% of the dust filtered by an equally sized birch forest.

Let's denote the amount of dust filtered by the small birch forest as 'x' tons. Since the coniferous forest filters 35 tons of dust, we can set up the following equation:

x = 0.5 * 35

Simplifying the equation, we find:

x = 17.5

Therefore, a small birch forest filters 17.5 tons of dust in one year.
