Question

Помогиет решить задачку с краткой записьюВ карьере за сутки добыто 5000 м3песка.Сколько железнодорожных платформ грузоподъёмностью 65 т потребуется , чтобы перевезти этот песок(песок пренять сухим)

Answer 1

Дано:
V-5000 м3
m1-65 т

p-1500 кг/м3

Найти:

N-?

Решение:
чтобы найти количество платформ необходимых для перевозки песка надо общую массу добытого песка поделить на  массу песка одной платформы
N=m/m1=>m=v*p

m=5000 м3 *1500 кг/м3=7500000=7500 т

N=7500 т/65 т=115 (вагонов)

Answer 2

Problem Analysis

To solve this problem, we need to determine the number of railway platforms with a carrying capacity of 65 tons that will be required to transport 5000 cubic meters of sand.

Solution

To find the number of railway platforms needed, we can follow these steps:

1. Convert the volume of sand from cubic meters to tons. Since the density of sand can vary, we will assume a density of 1.6 tons per cubic meter. Therefore, the weight of 5000 cubic meters of sand would be: ``` Weight = Volume * Density = 5000 * 1.6 = 8000 tons ```

2. Calculate the number of railway platforms needed by dividing the total weight of sand by the carrying capacity of each platform: ``` Number of platforms = Total weight / Carrying capacity = 8000 / 65 = 123.08 ```

Since we cannot have a fraction of a platform, we need to round up to the nearest whole number. Therefore, we would need 124 railway platforms with a carrying capacity of 65 tons each to transport 5000 cubic meters of sand.

Conclusion

To transport 5000 cubic meters of sand, you would need approximately 124 railway platforms with a carrying capacity of 65 tons each.
