Question

Бронза содержит (по массе) 41 часть меди, 8 частей олова и одну часть цинка. Какова масса куска бронзы, если в ней олова меньше чем меди на 132г

Answer 1

1) 41-8=33 (ч) - меньше олова, чем меди
2) 132:33=4 (г) - одна часть
3) 41×4=164 (г) - меди
4) 8×4=32 (г) - олова
5) 1×4=4 (г) - цинка
6) 164+32+4=200 (г) - масса куска бронзы

Answer 2

Calculating the Mass of the Bronze Piece

To calculate the mass of the bronze piece, we can use the given information about the composition of bronze and the difference in the masses of copper and tin.

Given: - Bronze contains 41 parts copper, 8 parts tin, and 1 part zinc by mass. - The difference in the mass of tin and copper is 132g.

Let's denote: - x as the mass of copper - y as the mass of tin

According to the given information, we have the following equations: 1. x + y = total mass of the bronze piece 2. x - y = 132g (since the mass of tin is less than copper by 132g)

Solving these equations will give us the mass of the bronze piece.

Solution

Using the given information, we can solve for the mass of the bronze piece:

From equation 2, we can express x in terms of y: x = y + 132g

Substituting this value of x into equation 1: (y + 132g) + y = total mass of the bronze piece 2y + 132g = total mass of the bronze piece

So, the mass of the bronze piece is 2y + 132g.

Final Answer

The mass of the bronze piece is 2y + 132g, where y is the mass of tin.
