Question

Решите 3 задачи срочно!!! 1)ферма каждый день поставляет на фабрику молоко:750л в бидонах по 30л и 240л в бидонах по 20л.В скольких бидонах привозят на фабрику молоко?2)на складе было 330 ящиков стекла. Когда со склада вывезли часть ящиков на 12 машинах на каждую поровну то осталось еще 126 ящиков Сколько ящиков стекла грузили на каждую машину?3) Хозяйка купила 9 кг огурцов и 6 кгпомидоров по одинаковой цене. За помидоры она заплатила на 75 руб. меньше. Сколько хозяйка заплатила за помидоры и огурцы в отдельности?

Answer 1

первая задача 1)750:30=25 2)240:20=12 3)25+12=37
вторая 1)

Answer 2

1)
750/30=25
240/20=12
25+12=37
2)
330-126=204
204/12=17
3)
9-6=3 значит за 3 кг заплатила 75
а за одну 75/3=25 руб
9*25=225
6*25=150

Answer 3

Problem 1:

The farm delivers 750 liters of milk to the factory every day, with 30-liter and 20-liter containers. We need to find out how many containers are used to transport the milk.

To solve this problem, we can use the following steps: 1. Calculate the number of 30-liter containers. 2. Calculate the number of 20-liter containers. 3. Add the results from steps 1 and 2 to find the total number of containers.

Let's start with step 1: Step 1: Calculate the number of 30-liter containers. We can use the following formula to calculate the number of 30-liter containers: \[ \text{Number of 30-liter containers} = \frac{\text{Total liters of milk}}{\text{Volume of each 30-liter container}} \]

Using the given values: \[ \text{Number of 30-liter containers} = \frac{750}{30} = 25 \]

Step 2: Calculate the number of 20-liter containers. Similarly, we can use the formula: \[ \text{Number of 20-liter containers} = \frac{\text{Total liters of milk}}{\text{Volume of each 20-liter container}} \] \[ \text{Number of 20-liter containers} = \frac{750}{20} = 37.5 \]

However, since we can't have a fraction of a container, we need to round up to the nearest whole number. Therefore, the number of 20-liter containers is 38.

Step 3: Add the results from steps 1 and 2 to find the total number of containers. \[ \text{Total number of containers} = \text{Number of 30-liter containers} + \text{Number of 20-liter containers} \] \[ \text{Total number of containers} = 25 + 38 = 63 \]

So, the farm brings the milk to the factory in 63 containers.

Problem 2:

The problem states that there were 330 boxes of glass on the warehouse, and after loading a portion of the boxes onto 12 trucks, an equal amount remained. We need to find out how many boxes of glass were loaded onto each truck.

To solve this problem, we can use the following steps: 1. Calculate the total number of boxes loaded onto the trucks. 2. Divide the total number of boxes by the number of trucks to find out how many boxes were loaded onto each truck.

Let's start with step 1: Step 1: Calculate the total number of boxes loaded onto the trucks. We can use the following formula to calculate the total number of boxes loaded onto the trucks: \[ \text{Total number of boxes loaded} = \text{Total number of boxes} - \text{Number of boxes remaining} \] \[ \text{Total number of boxes loaded} = 330 - 126 = 204 \]

Step 2: Divide the total number of boxes by the number of trucks to find out how many boxes were loaded onto each truck. \[ \text{Boxes loaded onto each truck} = \frac{\text{Total number of boxes loaded}}{\text{Number of trucks}} \] \[ \text{Boxes loaded onto each truck} = \frac{204}{12} = 17 \]

So, 17 boxes of glass were loaded onto each truck.

Problem 3:

The owner bought 9 kg of cucumbers and 6 kg of tomatoes at the same price. We need to find out how much the owner paid for tomatoes and cucumbers separately.

To solve this problem, we can use the following steps: 1. Set up an equation based on the given information. 2. Solve the equation to find the price per kilogram. 3. Calculate the total amount paid for tomatoes and cucumbers separately.

Let's start with step 1: Step 1: Set up an equation based on the given information. Let's assume the price per kilogram is \( x \) rubles. Then, the total amount paid for cucumbers and tomatoes can be expressed as: \[ 9x + 6x = \text{Total amount paid} \]

Step 2: Solve the equation to find the price per kilogram. \[ 9x + 6x = 75 \] \[ 15x = 75 \] \[ x = \frac{75}{15} = 5 \]

So, the price per kilogram is 5 rubles.

Step 3: Calculate the total amount paid for tomatoes and cucumbers separately. \[ \text{Amount paid for cucumbers} = 9 \times 5 = 45 \text{ rubles} \] \[ \text{Amount paid for tomatoes} = 6 \times 5 = 30 \text{ rubles} \]

Therefore, the owner paid **45
