Question

каждый день растительный мир даёт 117 млрд т прироста массы.каждые 3 т дают столько же энергии , сколько 1 т нефти .сколько тонн нефти может заменить прирост массы растений за 4 года

Answer 1

1) 117*4=468млрд. т- даёт за 4года

2)468:3=156млрд.т-смогут заменить прирост массы 

 

Answer 2

117:3=39млрд (т) - нефти заменяет растительный мир за 1 день

4 года = 365дней * 4 + 1 день = 1461(день) - 4года   (в високосном году на 1день больше - 366дней)

1461 * 39 = 56979 млрд(тонн)

Answer 3

Calculation of Oil Equivalent for Plant Mass Growth

To calculate the amount of oil equivalent that can replace the plant mass growth over a period of 4 years, we need to determine the total plant mass growth over that period and then convert it into oil equivalent.

Given that the plant world produces 117 billion tons of mass growth every day and that every 3 tons of plant mass growth is equivalent to the energy of 1 ton of oil, we can calculate the total plant mass growth over 4 years.

First, let's calculate the daily plant mass growth in oil equivalent: - 117 billion tons of plant mass growth per day - Every 3 tons of plant mass growth is equivalent to 1 ton of oil

To find the daily oil equivalent, we divide the plant mass growth by 3: 117 billion tons / 3 = 39 billion tons of oil equivalent per day

Next, let's calculate the yearly oil equivalent: 39 billion tons * 365 days = 14.235 trillion tons of oil equivalent per year

Finally, let's calculate the oil equivalent for 4 years: 14.235 trillion tons * 4 years = 56.94 trillion tons of oil equivalent

Therefore, the plant mass growth over 4 years can be replaced by approximately 56.94 trillion tons of oil equivalent.
