Question

Бронза, из которой делают статуи, состоит из меди, цинка и олова. масса меди составляет 85% массы всего сплава, а масса цинка равна 2/17 масса меди. остальная часть приходится на олова. сколько каждого метала пойдет на бронзовую статую массой 4 тонны? помогите очень нужно

Answer 1

4*0,85=3,4 т меди
3,4*2/17=0,4 т цинка
4-3,4-0,4=0,2 т олова
======================

Answer 2

1) 4×0,85=3,4(т)-меди.
2) 3,4×2/17=0,4(т)-цинка.
3)4-3,4-0,4=0,2(т)-олова.

Answer 3

Calculation of Metal Composition for a Bronze Statue

To determine the amount of each metal that will go into a bronze statue weighing 4 tons, we need to calculate the masses of copper, zinc, and tin based on the given composition.

According to the information provided, the bronze alloy consists of copper, zinc, and tin. The mass of copper accounts for 85% of the total alloy mass, while the mass of zinc is equal to 2/17 of the mass of copper. The remaining portion is made up of tin.

Let's calculate the masses of each metal:

1. Mass of Copper: - The mass of copper accounts for 85% of the total alloy mass. - Therefore, the mass of copper can be calculated as 85% of the total mass of the alloy. - Mass of Copper = 85% of Total Alloy Mass

2. Mass of Zinc: - The mass of zinc is equal to 2/17 of the mass of copper. - Therefore, the mass of zinc can be calculated as 2/17 of the mass of copper. - Mass of Zinc = (2/17) * Mass of Copper

3. Mass of Tin: - The remaining portion of the alloy is made up of tin. - Therefore, the mass of tin can be calculated as the difference between the total alloy mass and the sum of the masses of copper and zinc. - Mass of Tin = Total Alloy Mass - (Mass of Copper + Mass of Zinc)

Now, let's calculate the masses of each metal for a bronze statue weighing 4 tons:

1. Calculate the total mass of the alloy: - The total mass of the alloy is given as 4 tons. - Convert 4 tons to kilograms (1 ton = 1000 kg). - Total Alloy Mass = 4 tons * 1000 kg/ton

2. Calculate the mass of copper: - The mass of copper is 85% of the total alloy mass. - Mass of Copper = 85% of Total Alloy Mass

3. Calculate the mass of zinc: - The mass of zinc is equal to 2/17 of the mass of copper. - Mass of Zinc = (2/17) * Mass of Copper

4. Calculate the mass of tin: - The mass of tin is the difference between the total alloy mass and the sum of the masses of copper and zinc. - Mass of Tin = Total Alloy Mass - (Mass of Copper + Mass of Zinc)

Let's perform the calculations:

1. Total Alloy Mass: - Total Alloy Mass = 4 tons * 1000 kg/ton - Total Alloy Mass = 4000 kg

2. Mass of Copper: - Mass of Copper = 85% of Total Alloy Mass - Mass of Copper = 0.85 * 4000 kg - Mass of Copper = 3400 kg

3. Mass of Zinc: - Mass of Zinc = (2/17) * Mass of Copper - Mass of Zinc = (2/17) * 3400 kg - Mass of Zinc ≈ 400 kg

4. Mass of Tin: - Mass of Tin = Total Alloy Mass - (Mass of Copper + Mass of Zinc) - Mass of Tin = 4000 kg - (3400 kg + 400 kg) - Mass of Tin ≈ 200 kg

Therefore, for a bronze statue weighing 4 tons, the approximate masses of each metal are as follows: - Copper: 3400 kg - Zinc: 400 kg - Tin: 200 kg

Please note that these calculations are approximate and may vary depending on the specific composition of the bronze alloy used in the statue.
