Question

На шахте "Северная" добывают в 2 раза меньше угля,чем на шахте "Восточная". На сколько процентов добыча угля на шахте "Северной" ниже,чем на "Восточной"?

Answer 1

       нанананана 50 %

Answer 2

Северная = х : 2
Восточная = х
(х : 2) + х = 100%
2х : 100
х = 50
ответ на 50% добыча угля на шахте северная ниже чем на Восточная

Answer 3

Calculation of Coal Production Discrepancy

The coal production at the "Severnaya" mine is 2 times less than at the "Vostochnaya" mine. To calculate the percentage difference in coal production between the two mines, we can use the following formula:

Percentage Difference = ((V1 - V2) / V2) * 100

Where: - V1 = Coal production at the "Vostochnaya" mine - V2 = Coal production at the "Severnaya" mine

Using the given information, we can calculate the percentage difference in coal production between the two mines.

Calculation

Using the formula, the percentage difference in coal production between the "Severnaya" and "Vostochnaya" mines is:

Percentage Difference = ((V1 - V2) / V2) * 100

Given that the coal production at the "Severnaya" mine is 2 times less than at the "Vostochnaya" mine, we can represent the coal production at the "Severnaya" mine as 1/2 of the production at the "Vostochnaya" mine.

Substituting this into the formula: Percentage Difference = ((1 - 2) / 2) * 100 = (-1 / 2) * 100 = -50%

Conclusion

The percentage difference in coal production between the "Severnaya" and "Vostochnaya" mines is 50% lower at the "Severnaya" mine compared to the "Vostochnaya" mine.
