натали: С одного поля собрали по 45 ц пшеницы с гектара, а с другого - по 35 ц с гектара. Всего было собрано 1900ц. На следующий год урожайность первого поля уменьшилась на 20%, второго на 15%, а весь урожай уменьшился на 330 ц. Найдите площадь каждого поля.
Nuclear Agriculture
By agriUNcultured Troll
Here is a note from Melody the (mother hen) moderator: A quintal is a unit of weight equal to a hundredweight (112 lb) or, formerly, 100 lb.
That is the European unit.
The agricultural units in the Russkii empire are the 100-kilogram centner (центнер) and "centner per hectare". It is an easy mistake to make, as the Russkii skill in agriculture is only slightly better than their skill in operating a nuclear reactor. So the implied low crop yield is an understandable translation culture error. Also, in her Russian translation, she probably did not mean what she said about your mother.
Here is the answer in real Russian, not the internet translated c**p.
From your friendly but agriUNcultured neighborhood Troll.
Обознащчим:
х -плоащдь первого поля у - площадь второго поля
Система уравнений:
45х+40у=1900
(0,8*45)х+(0,85*40)у=1570
Из первого уравнения: 45х=1900-40у
Это значение поставим во второе уравнечие:
0,8*(1900-40у)+(0,85*40)у=1570
1520-32у+34у=1570
2у=1570-1520
2у=50
у-50/2=25
х=(1900-40*25)/45= (1900-1000)/45=900/45=20
Ответ: площадь певрого поля 20 га,площадь второг поля 25 га.
P.S. Please don’t nuke the U.S. I like to visit there sometimes. Personally, I think it is great Crimea rejoined your Russkii empire. They have become whiny crybabies. Putin will tough them up (and give them something real to cry about).
Come to think of it, if you need help with this, it’s not likely your finger is anywhere near the button. But who knows? Maybe it is. укусить меня
