Question

В первом ведре 12 л воды, а во втором на 4 л меньше,чем в первом.Объём водлы в двух ведрах вместе на 20л меньше,чем в бочке.Чему равна вместимость бочки.Помогите решить пожалуйста и схему.

Answer 1

Решение:
1) 12-4=8(литров) - во 2 ведре
2) 12+8=20(литров) - в двух вёдрах вместе.
3) 20+2=40(литров) - вместимость бочки. 

Answer 2

Problem Analysis

To solve this problem, we need to determine the capacity of the barrel given the information about the volumes of water in two buckets and the difference in volume between the combined buckets and the barrel.

Let's break down the information provided: - The first bucket contains 12 liters of water. - The second bucket contains 4 liters less than the first bucket. - The combined volume of water in both buckets is 20 liters less than the volume of the barrel.

We need to find the capacity of the barrel.

Solution

Let's assume the capacity of the barrel is x liters.

According to the given information: - The first bucket contains 12 liters of water. - The second bucket contains 4 liters less than the first bucket, so it contains (12 - 4) = 8 liters of water. - The combined volume of water in both buckets is 20 liters less than the volume of the barrel, so the combined volume of water in both buckets is (x - 20) liters.

To find the capacity of the barrel, we can sum up the volumes of water in both buckets and equate it to the combined volume of water in both buckets: 12 liters + 8 liters = (x - 20) liters

Simplifying the equation: 20 liters = (x - 20) liters

Adding 20 liters to both sides of the equation: 20 liters + 20 liters = x liters 40 liters = x

Therefore, the capacity of the barrel is 40 liters.

Here is a diagram representing the given information:

First Bucket: 12 liters
Second Bucket: 8 liters
Combined Volume of Buckets: 20 liters less than the barrel
Barrel Capacity: 40 liters
