Question

крестьянским хозяйством заготовлено корма на 184 дня для 75 коров.На сколько дней хватит этого корма,если увеличить поголовье на 40 коров?

Answer 1

Обратная пропорциональность:

чем больше коров 75+40=115, тем на меньшее кол-во дней хватит корма, составим пропорцию:

х:75=184:115

х=75*184/115

х=120

Ответ: корма хватит на 120 дней

Answer 2

1) 75+40=115 (коров)

2) 184:х=115:75

    х=184*75:115=120 (дней)

 

Answer 3

Calculation of Feed Supply for 75 Cows

To determine how long the feed supply will last for 75 cows, we need to know the amount of feed that is available and the daily feed consumption per cow.

According to the information provided, the feed supply is sufficient for 184 days for 75 cows. However, we need to calculate the daily feed consumption per cow to determine the total amount of feed required for 75 cows.

To calculate the daily feed consumption per cow, we can divide the total feed supply (184 days) by the number of cows (75):

Daily feed consumption per cow = Total feed supply / Number of cows

Let's calculate the daily feed consumption per cow:

Daily feed consumption per cow = 184 days / 75 cows

Using this calculation, we find that the daily feed consumption per cow is approximately 2.45 days.

Calculation of Feed Supply for 115 Cows

Now, let's calculate how long the feed supply will last if the number of cows increases to 115.

To calculate the new feed supply duration, we need to determine the total amount of feed required for 115 cows.

Using the daily feed consumption per cow calculated earlier (2.45 days), we can calculate the new feed supply duration:

New feed supply duration = Total feed supply / Daily feed consumption per cow

Let's calculate the new feed supply duration:

New feed supply duration = 184 days / 2.45 days

Using this calculation, we find that the new feed supply duration is approximately 75.10 days.

Therefore, if the number of cows increases from 75 to 115, the feed supply will last approximately 75.10 days.

Please note that these calculations are based on the information provided and assume a constant daily feed consumption per cow. Factors such as changes in feed quality, cow health, and other variables may affect the actual feed consumption and duration of the feed supply.
