Question

Реши задачи. 1) На двух опытных участках вырастили картофель. Площадь первого участка 200м(в квадрате), а второго 300м( в квадрате). С первого участка собрали на 1500кг картофеля меньше, чем со второго. Сколько килограммов картофеля собрали с каждого участка, если с каждого квадратного метра собирали поровну? 2) С двух опытных участков собрали 7500кг картофеля. Площадь первого участка 200м( в квадрате), а второго 300м ( в квадрате). С каждого квадратного метра собирали картофеля поровну. Сколько килограммов картофеля собрали с каждого участка? ПАЖАЛУЙСТА!!! это срочно.

Answer 1

1) 300-200=100
со 100 м^2 собрали 1500 кг
с первого участка собрали 2*1500=3000кг
со второго участка собрали 3*1500=4500кг

2) с одного м^2 собрали 7500/500= 15кг
с первого участка собрали 200*15=3000кг
со второго участка собрали 300*15=4500кг

Answer 2

Task 1: Harvesting Potatoes from Two Plots

To solve this problem, we need to find out how many kilograms of potatoes were harvested from each plot, given that the yield per square meter was the same for both plots.

Let's denote the yield per square meter as x kg/m².

The area of the first plot is 200 m², and the area of the second plot is 300 m².

From the first plot, 1500 kg less potatoes were harvested compared to the second plot.

To find the yield from each plot, we can set up the following equations:

For the first plot: 200 * x = (yield from the second plot) - 1500 (equation 1)

For the second plot: 300 * x = (yield from the second plot) (equation 2)

To solve this system of equations, we can substitute equation 2 into equation 1:

200 * x = (300 * x) - 1500

Simplifying the equation:

200 * x - 300 * x = -1500

-100 * x = -1500

Dividing both sides by -100:

x = 15

Therefore, the yield per square meter is 15 kg/m².

Now we can calculate the total yield from each plot:

For the first plot: 200 * 15 = 3000 kg

For the second plot: 300 * 15 = 4500 kg

So, from the first plot, 3000 kg of potatoes were harvested, and from the second plot, 4500 kg of potatoes were harvested.

Task 2: Total Harvest from Two Plots

In this task, we are given the total harvest of 7500 kg of potatoes from two plots, with areas of 200 m² and 300 m² respectively. The yield per square meter is the same for both plots.

Let's denote the yield per square meter as x kg/m².

To find the yield from each plot, we can set up the following equations:

For the first plot: 200 * x = (total harvest) / 2 (equation 1)

For the second plot: 300 * x = (total harvest) / 2 (equation 2)

Since the total harvest is given as 7500 kg, we can substitute this value into equations 1 and 2:

For the first plot: 200 * x = 7500 / 2 = 3750 kg

For the second plot: 300 * x = 7500 / 2 = 3750 kg

Therefore, from each plot, 3750 kg of potatoes were harvested.

To summarize:

- From the first plot, 3750 kg of potatoes were harvested. - From the second plot, 3750 kg of potatoes were harvested.
