Question

Норма высева овса 220 кг на 1 га. Сколько центнеров овса потребуется для засева прямоугольного участка, размеры которого на плане 1 : 10 000 равны 5 см на 8 см?

Answer 1

Ответ:

Пошаговое объяснение:

5×10 000=50 000см =500м ширина

8×10 000=80 000см=800м длина

500×800=400 000м² площадь поля

1га=10 000м²

400 000÷10 000=40 га площадь поля

40×220=8800кг семян потребуется

Answer 2

Calculating Oat Seeds Required for Planting

To calculate the amount of oat seeds required for planting a rectangular plot, we can use the formula:

Amount of seeds (in kg) = (Area of plot in hectares) x (Seed rate in kg per hectare)

Given: - Seed rate for oats: 220 kg per hectare - Dimensions of the plot on the plan: 5 cm x 8 cm - Conversion factor from cm^2 to hectares: 1 hectare = 10,000 m^2

First, we need to convert the plot dimensions from cm^2 to hectares: - Area of the plot = (5 cm x 8 cm) = 40 cm^2 - Converting cm^2 to m^2: 40 cm^2 = 0.0004 m^2 - Converting m^2 to hectares: 0.0004 m^2 = 0.00000004 hectares

Now, we can calculate the amount of oat seeds required: - Amount of seeds = (0.00000004 hectares) x (220 kg per hectare)

Amount of seeds = 0.00000004 hectares x 220 kg/hectare = 0.0000088 kg

So, for the given rectangular plot with dimensions 5 cm x 8 cm, approximately 0.0000088 kg of oat seeds will be required for planting.
