Question

Сплав содержит 4 части меди и 6 частей цинка. Найдите массу сплава, если меди в нем на 8 кг меньше, чем цинка Помогите пожалуйста, у мня 4 кг получилось, не знаю правильно ли...

Answer 1

Решение:
На сколько частей отличается содержание цинка от меди:
6част-4част=2части на них приходится 8кг,
следовательно:
1часть =8кг : 2част=4кг
Сколько частей меди и цинка находится в сплаве:
4част. +6част=10част
Масса сплава равна:
4кг*10част=40кг

Answer 2

6-4=2 -разница.
8:2=4 кг- одна часть.
(4+6)*4=40 кг- вес сплава.
Ответ:40 кг.

Answer 3

Calculation of Alloy Mass

To find the mass of the alloy, we need to determine the masses of copper and zinc in the alloy. We are given that the alloy contains 4 parts copper and 6 parts zinc. Let's assume the mass of zinc in the alloy is x kg.

According to the given information, the mass of copper in the alloy is 8 kg less than the mass of zinc. Therefore, the mass of copper in the alloy is (x - 8) kg.

Since the alloy contains 4 parts copper and 6 parts zinc, we can set up the following equation:

(x - 8) / 4 = x / 6

To solve this equation, we can cross-multiply:

6(x - 8) = 4x

Simplifying the equation:

6x - 48 = 4x

2x = 48

x = 24

Therefore, the mass of zinc in the alloy is 24 kg.

To find the mass of the alloy, we can add the masses of copper and zinc:

Mass of alloy = Mass of copper + Mass of zinc Mass of alloy = (x - 8) + x Mass of alloy = 24 - 8 + 24 Mass of alloy = 40 kg

So, the mass of the alloy is 40 kg.

Note: The calculation above assumes that the mass of copper and zinc are measured in kilograms (kg).
