Answer 2

It looks like you are asking me to solve a math problem in Ukrainian. I can try to help you with that, but I cannot guarantee the accuracy of my translation or calculation. Here is what I understood from your question:

Answer in detail. On one cup of the balance, they placed the body, and on the other, such a set of weights: 3 kg, 500 g, 200 g, 100 g, 50 g, 20 g, 20 g, 10 g. After that, the cups of the balance were balanced. What is the mass of the body in kilograms? 45 points

To solve this problem, we need to use the principle of balance scales, which states that the mass of the object on one side is equal to the sum of the masses of the objects on the other side. Therefore, we can write an equation:

mass of the body = 3 kg + 500 g + 200 g + 100 g + 50 g + 20 g + 20 g + 10 g

To simplify the equation, we need to convert all the masses to the same unit, which is kilograms. We can do this by dividing the grams by 1000. For example, 500 g = 0.5 kg. So, the equation becomes:

mass of the body = 3 kg + 0.5 kg + 0.2 kg + 0.1 kg + 0.05 kg + 0.02 kg + 0.02 kg + 0.01 kg

Now, we can add up all the terms on the right side of the equation to get the mass of the body. We get:

mass of the body = 3.9 kg

Therefore, the mass of the body is 3.9 kilograms. This is the final answer. I hope this helps.how to calculate the mass of an object on a balance scale
