Пошаговое объяснение:

4.35*1000=4350 кг

4350-1541=2809 кг - второй день

(4350+2809)-1,76*1000=7159-1760=5399 кг - третий день

4350+2809+5399=12588 кг - за три дня  

12588/1000=12,588 т

ENGLISH CHARACTER

One of the most striking features of English life is the self-discipline
and courtesy of people of all classes. There is little noisy behaviour, and
practically no loud disputing in the street. People do not rush excitedly for
seats in buses or trains, but take their seats in queues at bus stops in a
quiet and orderly manner. Englishmen are naturally polite and are never tired
in saying •Thank you*, «I'm sorry*, •Beg your pardon*. If you follow anyone who
is entering a building or a room, he will hold a door open for you. Many
foreigners have commented on a remarkable politeness of the English people. ,
English people don't like displaying their emotions even in dangerous and
tragic situations, and ordinary people seem to remain good-tempered and
cheerful under difficulties. The Englishman does not like any boasting or showing
off in manners, dress or speech. Sometimes he con coals his knowledge: a
linguist, for example, may not mention his understanding of a foreigner's
language. The Englishman prefers his own house to an apartment in a block of
flats, because he doesn't wish his doing to be overlooked by his neighbors. «An
English man's house is his castle*. Many Englishmen help the wives at home in
many ways. They clean the windows on Saturday afternoon they often wash up the
dishes after supper in the evening. Sunday is a very quiet day in London. All
the shops are closed, and so are the theatres and most of the cinemas.
Londoners like to get out of town on Sundays. The sea is not far — only fifty
or sixty miles away and people like to go down to the sea in summer or
somewhere to the country for skiing in winter.
