Question

Очень надо))чтобы вспахать поле в установленный план и срок совхоз должен был вспахать ежедневно по 56 га.Перевыполняя план, совхоз вспахивал ежедневно по 64 га,потому за 2 дня до срока ему осталось вспахать только 40 га .Сколько га земли должен был вспахать совхоз по плану.

Answer 1

По-моему так: х—кол-во га земли,которое совхоз должен был вспахать по плану; х/56—кол-во дней вспашки по плану; х/64—кол-во дней фактически; х/56-112—кол-во га за 2 дня до указанного срока по плану; х/64-128-кол-во га за 2 дня до указанного срока фактически. Имеем уравнение: х/64-128=40; х-128*64=40*64; х=8192+2560; х=10752. Теперь вычислим кол-во га, которое должно было быть вспахано по плану: 10752/56=192. Ответ: 192

Answer 2

Calculating the Total Area to be Plowed

To calculate the total area that the farm should have plowed according to the plan, we can use the information provided.

According to the information: - The farm was supposed to plow 56 hectares daily. - However, the farm plowed 64 hectares daily, exceeding the plan. - Two days before the deadline, the farm had 40 hectares left to plow.

To find out how much land the farm should have plowed according to the plan, we can use the following calculation:

Total area to be plowed = (Plowing rate per day) x (Number of days)

Using the given information, we can calculate the total area the farm should have plowed according to the plan.

Calculation

Total area to be plowed = (56 hectares/day) x (Number of days)

Given that the farm had 40 hectares left to plow two days before the deadline, we can calculate the number of days it had to plow.

Number of days = (Total area left to plow) / (Plowing rate per day)

Let's calculate the number of days the farm had to plow and then use it to find the total area the farm should have plowed according to the plan.

Solution

Number of days = 40 hectares / 56 hectares/day Number of days = 0.7143 days (rounded to 4 decimal places)

Now, we can use the number of days to find the total area the farm should have plowed according to the plan.

Total area to be plowed = 56 hectares/day x 0.7143 days Total area to be plowed ≈ 40 hectares

Therefore, according to the plan, the farm should have plowed approximately 40 hectares in total.
