Question

Колхоз засеял пшеницей два поля. площадь 1 поля-75 га, площадь 2 поля-на 50 меньше. с первого поля собрали урожай 2580 ц, со второго 720 ц. чему равна средняя урожаиность в этом колхозе

Answer 1

75-50=25 га площадь 2-го поля
75+25=100 га общая площадь полей
2580+720 =3300 ц урожай с двух полей
3300:100=33 ц/га
Ответ 33 центнера с гектара

Answer 2

Calculation of Average Yield in the Collective Farm

To calculate the average yield in the collective farm, we need to determine the total yield from both fields and divide it by the total area of the fields.

Let's denote the area of the first field as A1 and the area of the second field as A2. We are given that the area of the first field is 75 hectares (ha) and the area of the second field is 50 hectares less than the first field.

Therefore, the area of the second field can be expressed as A2 = A1 - 50.

Next, we are given the yield from each field. The yield from the first field is 2580 centners (ц) and the yield from the second field is 720 centners.

To calculate the average yield, we need to find the total yield from both fields and divide it by the total area of the fields.

The total yield from both fields can be calculated as follows: Total Yield = Yield from First Field + Yield from Second Field

The total area of the fields can be calculated as follows: Total Area = Area of First Field + Area of Second Field

Finally, the average yield can be calculated as follows: Average Yield = Total Yield / Total Area

Let's substitute the given values into the formulas and calculate the average yield.

Given: Area of First Field (A1) = 75 ha Area of Second Field (A2) = A1 - 50 Yield from First Field = 2580 ц Yield from Second Field = 720 ц

Calculation: Total Yield = 2580 ц + 720 ц Total Area = 75 ha + (75 ha - 50 ha)

Substituting the values: Total Yield = 3300 ц Total Area = 75 ha + 25 ha = 100 ha

Average Yield = Total Yield / Total Area Average Yield = 3300 ц / 100 ha

Therefore, the average yield in this collective farm is 33 ц/ha.
