Question

Чтобы за один раз перевезти груз массой 36,2 т, выделили машины трёх видов различной вместимости: две машины вместимотью, ,1,8 т. каждая три машины вметимостью 3 2\5 т. каждая и четыре машины третьего вида. Найдите вместимость третьего вида. Помогите пожалуйста срочно

Answer 1

2 по 1,8 т=3,6 т.
3 по 3 2/5= 10 1/5т
3,6+ 10 1/5=3,6+10,2=13,8 увезут машины 1-го и 2-го вида.
36,2-13,8=22,4т  останется для машин 3-го вида
22,4:4=5,6т вместимость машин третьего вида

Answer 2

Calculating the Capacity of the Third Type of Truck

To find the capacity of the third type of truck, we can use the information provided about the total mass of the cargo and the capacities of the other two types of trucks.

Let's denote: - Capacity of the first type of truck as x tons - Capacity of the second type of truck as y tons

Given: - Two trucks with a capacity of 1.8 tons each - Three trucks with a capacity of 3 2/5 tons each - Total mass of the cargo is 36.2 tons

We can set up the following equation to find the capacity of the third type of truck: 2x + 3(3 2/5) + 4z = 36.2

Solving for the Capacity of the Third Type of Truck

Let's solve for the capacity of the third type of truck:

2x + 3(3 2/5) + 4z = 36.2 2x + 10 6/5 + 4z = 36.2 2x + 10.2 + 4z = 36.2 2x + 4z = 26

We need to find a value for z that satisfies this equation.

Calculating the Capacity

Let's calculate the capacity of the third type of truck:

2x + 4z = 26

Given that x = 1.8 (capacity of the first type of truck) and y = 3 2/5 (capacity of the second type of truck), we can solve for z.

2(1.8) + 4z = 26 3.6 + 4z = 26 4z = 26 - 3.6 4z = 22.4 z = 22.4 / 4 z = 5.6

The capacity of the third type of truck is 5.6 tons.
