Question

Бронза содержит(по массе)41 часть меди,8 частей олова и 1 часть цинка.какова масса куска бронзы,если в ней олова меньше,чем меди,на 132 грамма?

Answer 1

1)41-8=33(ч)-132грамма;

2)132/33=4(г)-одна часть;

3)41*4=164(г)-Медь;

4)8*4=32(г)-Олово;

5)1*4=4(г)-Цинк;

6)164+32+4=200(г)

Ответ:200грамм

Answer 2

41-8 = 33 части олова больше меди

132:33= 4 гр масса одной части

4*(41+8+1) = 4*50=200 грамм масса всего куска

Answer 3

Calculation of the Mass of the Bronze

To calculate the mass of the bronze, we need to determine the mass of the copper and tin in the alloy and then add them together.

Given: - Bronze contains 41 parts copper, 8 parts tin, and 1 part zinc by mass. - There is a difference of 132 grams between the mass of tin and copper in the bronze.

Let's assume the mass of copper in the bronze is x grams. Then, the mass of tin in the bronze would be (x - 132) grams.

To find the mass of the bronze, we can use the following equation:

x + (x - 132) + (x/41 + (x - 132)/8 + x/41 + (x - 132)/8 + x/41 + (x - 132)/8) = x + (x - 132)

Simplifying the equation, we get:

8x + 8(x - 132) + 41x + 41(x - 132) + 41x + 41(x - 132) + 41x + 41(x - 132) = 41x + 41(x - 132)

Solving the equation, we find:

x = 396

Therefore, the mass of copper in the bronze is 396 grams, and the mass of tin in the bronze is (396 - 132) = 264 grams.

To find the mass of the bronze, we add the mass of copper and tin:

Mass of bronze = Mass of copper + Mass of tin = 396 grams + 264 grams = 660 grams

Therefore, the mass of the bronze is 660 grams.

Note: The above calculation assumes that the mass of zinc is negligible compared to the mass of copper and tin in the bronze alloy.
