Question

Тракторная бригада вспахала за три дня 260 гектаров.в1день она вспахала 35%Всей площади,а во 2-на 4 га больше,чем в первый.Какую площадь вспахала бригада в 3 день? с решением ППППЖЖЖЖЖЖЖЖЖЖЖЖЖ СРОЧНО

Answer 1

35%=0,35
260*0,35=91(га) - І день
91+4=95(га) - ІІ день
91+95=186(га) - в І и ІІ день
260-186=74(га) - в ІІІ день

Answer 2

Calculation of the Total Area Plowed by the Tractor Brigade

To determine the area plowed by the tractor brigade on the third day, we need to calculate the area plowed on the first and second days.

Let's assume the total area to be plowed is represented by A.

On the first day, the tractor brigade plowed 35% of the total area, which is 0.35A.

On the second day, they plowed 4 hectares more than on the first day. Since 1 hectare is equal to 10,000 square meters, 4 hectares is equal to 40,000 square meters. Therefore, the area plowed on the second day is 0.35A + 40,000 square meters.

To find the total area plowed by the brigade in three days, we need to sum up the areas plowed on the first, second, and third days.

Let's calculate the area plowed on the third day.

Calculation of the Area Plowed on the Third Day

To find the area plowed on the third day, we need to subtract the areas plowed on the first and second days from the total area.

The area plowed on the third day can be calculated as follows:

Area plowed on the third day = Total area - (Area plowed on the first day + Area plowed on the second day)

Let's substitute the values we have:

Area plowed on the third day = A - (0.35A + 40,000 square meters)

Simplifying the equation:

Area plowed on the third day = A - 0.35A - 40,000 square meters

Combining like terms:

Area plowed on the third day = 0.65A - 40,000 square meters

Therefore, the tractor brigade plowed an area of 0.65A - 40,000 square meters on the third day.

Please note that the exact value of the area plowed on the third day depends on the total area to be plowed, which is not provided in the question.
