Question

Для перевозки груза автомашине грузоподъемностью 7,5 т пришлось сделать 12 рейсов. сколько рейсов необходимо сделать автомашине грузоподъемностью 9 тонн для перевозки этого груза. решение в пропорциях

Answer 1

7,5:9=х:12

7,5*12=9х

90=9х

х=10 рейсов

ответ:10 рейсов

Answer 2

7.5 тонн-12рейсов
9тонг-х рейсов
Х=(12×7.5)÷9
Х=90÷9
Х=10
Ответ 10 рейсов.

Думаю так.

Answer 3

Calculating the Number of Trips Required for Transporting Cargo

To calculate the number of trips required for transporting the cargo, we can use the following proportion:

7.5 tons is to 12 trips as x tons is to y trips

Using the given information, we can set up the proportion as follows:

7.5 / 12 = x / y

Now, we can solve for y, which represents the number of trips needed for a 9-ton capacity truck to transport the same cargo.

Solving the Proportion

To solve for y, we can use the proportion:

7.5 / 12 = 9 / y

Cross-multiplying, we get:

7.5y = 108

Dividing both sides by 7.5, we find:

y = 14.4

So, it would take approximately 14.4 trips for a 9-ton capacity truck to transport the same cargo that required 12 trips for a 7.5-ton capacity truck.

This calculation is based on the given information and the proportion set up.
