Question

Некоторый сплав состоит из 3 частей меди(по массе),5 частей свинца и 2 частей алюминия.Деталь из этого сплава весит 30 кг . Сколько алюминия содержит эта деталь .помогите пожалуйста :(

Answer 1

3+5+2=10частей всего
30 : 10 = 3кг 1 часть
3*2 = 6 кг. алюминия.

Answer 2

Calculation of Aluminum Content in the Alloy

To determine the amount of aluminum in the given alloy, we need to calculate the mass of aluminum in the alloy.

The alloy consists of 3 parts copper, 5 parts lead, and 2 parts aluminum. Since the total number of parts is 3 + 5 + 2 = 10, we can consider each part as 1/10th of the total mass of the alloy.

Given that the total weight of the alloy is 30 kg, we can calculate the mass of aluminum as follows:

Mass of aluminum = (2/10) * 30 kg = 6 kg.

Therefore, the given detail contains 6 kg of aluminum.
