Question

На складе имеется запас угля. Ежедневно на склад привозят 42 т. угля , а со склада увозят 50 т. Как из-меняется за день количество угля на складе?Как оно изменется за 5 дней? Каким оно станет через 5 дней,если сейчас на складе 140 т. угля.

Answer 1

Как из-меняется за день количество угля на складе?

       50т.-42т.=8т---------на 8 т. будет уменьшаться количества угля на складе.

Как оно изменется за 5 дней?

      8*5= 40т.-  за 5 дней количество на складе угля уменьшиться на 40т

Каким оно станет через 5 дней, если сейчас на складе 140 т. угля?

     1) 42*5=210(т)- привезут за 5 дней;

     2) 50*5=250(т)-увезут за 5 дней;

     3) 140+210=350(т) - на складе;

     4) 350-250=100(т)- останется

через пять дней угля станет 100 тонн

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Answer 2

Calculation of Coal Stock Changes

To calculate the changes in the amount of coal in stock, we need to consider the daily inflow and outflow of coal.

Given the following information: - Daily inflow of coal: 42 tons - Daily outflow of coal: 50 tons

We can calculate the change in the amount of coal on a daily basis by subtracting the outflow from the inflow:

Change in coal stock per day = Inflow - Outflow = 42 tons - 50 tons = -8 tons

This means that the coal stock decreases by 8 tons every day.

Change in Coal Stock over 5 Days

To calculate the change in the amount of coal on the stock over 5 days, we can multiply the daily change by the number of days:

Change in coal stock over 5 days = Change per day * Number of days = -8 tons/day * 5 days = -40 tons

This means that the coal stock will decrease by 40 tons over 5 days.

Final Coal Stock after 5 Days

To determine the final amount of coal on the stock after 5 days, we need to subtract the change in coal stock over 5 days from the initial amount of coal on the stock.

Given the initial amount of coal on the stock is 140 tons, we can calculate the final amount as follows:

Final coal stock after 5 days = Initial stock - Change over 5 days = 140 tons - 40 tons = 100 tons

Therefore, after 5 days, the coal stock will be 100 tons.

Please note that the calculations above assume a constant daily inflow and outflow of coal and do not take into account any other factors that may affect the stock levels.
