Answer 1

Ответ:

Пошаговое объяснение:

270000:9*4= 120000 штук первая неделя

120000*10%=12000 на 12000 шт больше

120000+12000=132000  во вторую неделю

270000-(120000+1320000)=18000 шт осталось  

Answer 2

Problem Analysis

To solve this problem, we need to calculate the number of bricks that the brick factory still needs to produce for the construction of the Palace of Culture. We are given that the factory was supposed to produce 270,000 bricks. In the first week, they produced 4/9 of the target, and in the second week, they produced 10% more than in the first week.

Calculation

Let's calculate the number of bricks produced in the first week:

Bricks produced in the first week = (4/9) * 270,000

Now, let's calculate the number of bricks produced in the second week:

Bricks produced in the second week = (1 + 10/100) * (4/9) * 270,000

To find the number of bricks remaining to be produced, we subtract the total number of bricks produced from the target number of bricks:

Bricks remaining to be produced = 270,000 - (Bricks produced in the first week + Bricks produced in the second week)

Let's calculate the values:

Bricks produced in the first week = (4/9) * 270,000 = 120,000

Bricks produced in the second week = (1 + 10/100) * (4/9) * 270,000 = 160,000

Bricks remaining to be produced = 270,000 - (120,000 + 160,000) = 270,000 - 280,000 = -10,000

Answer

According to the calculations, the brick factory has produced 280,000 bricks, which is 10,000 more than the target of 270,000 bricks. Therefore, the factory has produced more bricks than required, and there are no bricks left to be produced.

Please note that the calculations are based on the given information and assumptions made.
