Question

На поле площадью 26,4 га урожайность проса составила 6,6 ц с 1 га, на поле площадью 30,8 га урожайность была 6,3 ц с 1 га, и на поле площадью 22 га - 7,2 га с 1 га. Найдите среднюю урожайность проса на всей лощади.

Answer 1

1)26.4*6.6=174.24ц-с первого поля.

2)30.8*6.3=194.04ц-со второго поля.

3)22*7.2=158.4ц-с третьего поля.

4)174.24+194.04+158.4=526.68ц-собрали всего.

5)26.4+30.8+22=79.2га-общая площадь.

6)526.68:79.2=6.65ц/га-средняя урожайность.

ОТВЕТ: 6.65ц/га.

Answer 2

Calculation of Average Yield of Millet

To calculate the average yield of millet on the entire area, we need to find the total yield of millet and divide it by the total area.

Given the following information:

- Field 1: Area = 26.4 hectares, Yield = 6.6 quintals per hectare - Field 2: Area = 30.8 hectares, Yield = 6.3 quintals per hectare - Field 3: Area = 22 hectares, Yield = 7.2 quintals per hectare

We can calculate the total yield of millet by multiplying the yield per hectare by the area for each field:

- Total yield from Field 1 = 26.4 hectares * 6.6 quintals per hectare - Total yield from Field 2 = 30.8 hectares * 6.3 quintals per hectare - Total yield from Field 3 = 22 hectares * 7.2 quintals per hectare

To find the average yield, we add up the total yields from all the fields and divide by the total area:

- Total yield = Total yield from Field 1 + Total yield from Field 2 + Total yield from Field 3 - Total area = Area of Field 1 + Area of Field 2 + Area of Field 3

Finally, we calculate the average yield:

- Average yield = Total yield / Total area

Let's perform the calculations:

Total yield from Field 1 = 26.4 hectares * 6.6 quintals per hectare = 174.24 quintals Total yield from Field 2 = 30.8 hectares * 6.3 quintals per hectare = 194.04 quintals Total yield from Field 3 = 22 hectares * 7.2 quintals per hectare = 158.4 quintals

Total yield = 174.24 quintals + 194.04 quintals + 158.4 quintals = 526.68 quintals Total area = 26.4 hectares + 30.8 hectares + 22 hectares = 79.2 hectares

Average yield = 526.68 quintals / 79.2 hectares ≈ 6.64 quintals per hectare.

Therefore, the average yield of millet on the entire area is approximately 6.64 quintals per hectare.
