Answer 2

Problem 1: Number of Paintings at the Exhibition

To solve this problem, we need to determine the total number of paintings at the exhibition. We are given the following information:

- Total number of paintings: 78 - Number of landscapes: 25 - Number of portraits: 9 more than the number of landscapes - The remaining paintings are still lifes (natyurmorty)

Let's calculate the number of paintings at the exhibition:

1. Number of portraits: Since the number of portraits is 9 more than the number of landscapes, we can calculate it as follows: - Number of portraits = Number of landscapes + 9 - Number of portraits = 25 + 9 - Number of portraits = 34

2. Number of still lifes (natyurmorty): To find the number of still lifes, we subtract the number of landscapes and portraits from the total number of paintings: - Number of still lifes = Total number of paintings - Number of landscapes - Number of portraits - Number of still lifes = 78 - 25 - 34 - Number of still lifes = 19

Therefore, the total number of paintings at the exhibition is 78.

Answer: There are 78 paintings at the exhibition.

Problem 2: Number of Mushrooms Found by Masha, Vanya, and Olya

In this problem, we need to find the number of mushrooms found by Masha, Vanya, and Olya. We are given the following information:

- Masha found 30 mushrooms. - Vanya found 26 mushrooms. - Olya found the same number of mushrooms as Masha and Vanya combined.

Let's calculate the number of mushrooms found by Olya:

1. Number of mushrooms found by Olya: Since Olya found the same number of mushrooms as Masha and Vanya combined, we can calculate it as follows: - Number of mushrooms found by Olya = Number of mushrooms found by Masha + Number of mushrooms found by Vanya - Number of mushrooms found by Olya = 30 + 26 - Number of mushrooms found by Olya = 56

Therefore, the number of mushrooms found by Olya is 56.

Answer: Olya found 56 mushrooms.

Problem 3: Length of a Broken Line

In this problem, we need to find the length of a broken line composed of four segments, with each segment measuring 3 dm (decimeters).

To find the length of the broken line, we need to calculate the sum of the lengths of all four segments:

1. Length of each segment: Each segment measures 3 dm.

2. Total length of the broken line: To find the total length, we multiply the length of each segment by the number of segments: - Total length = Length of each segment * Number of segments - Total length = 3 dm * 4 - Total length = 12 dm

Therefore, the length of the broken line is 12 decimeters (dm).

Answer: The length of the broken line is 12 decimeters (dm).

Problem 4: Volume of Milk in Five Containers

In this problem, we need to find the total volume of milk in five containers, assuming that each container has an equal amount of milk.

We are given the following information:

- There are five containers. - The volume of milk in each container is the same.

To find the volume of milk in each container, we need to divide the total volume of milk by the number of containers:

1. Volume of milk in each container: Since the volume of milk is divided equally among the five containers, we can calculate it as follows: - Volume of milk in each container = Total volume of milk / Number of containers

2. Total volume of milk: The total volume of milk is not provided in the problem statement. If you have the total volume of milk, you can substitute it into the formula above to find the volume of milk in each container.

Please provide the total volume of milk in order to solve this problem.

Answer: To solve this problem, we need the total volume of milk in order to calculate the volume of milk in each container. Please provide the total volume of milk.
