Вопрос школьника по предмету Математика
площадку длиной 11,6 метров и шириной 8,7 М надо покрыть плиты имеющие длины 4,35 см и шириной 2,9 дециметра Хватит ли 750 на покрытие площадки
Ответ учителя по предмету Математика
11,6*8,7=100,92(м²)= — площадь площадки
4,35 дм = 0,435 м
2,9 дм = 0,29 м
0,435*0,29=0,12615 м²- площадь плиты
100,92:0,12615=800(плит)- нужно
800>750⇒ не хватит 750 плит на покрытие площадки

It was in 1947, and Jean and Tom were going to get married. But after the Second
World War it was very difficult to buy new clothes in Britain. “Do not worry”, Jean’s
dad said to Tom. “You can takemy suit”. “What shall I wear?” thought Jean.
She remembered an advertisement in her favourite magazine, “Picturegoer”: “British Film
Studios three-day wedding hire services”.
They hired out dresses from films. She had saved £3 before the war, and it was enough.
Jean filled in the form giving them the size. The dress arrived in time. It was
beautiful, and Jean looked perfect in it. Their wedding day was wonderful.
Now they have been married for 53 years. They always watch the old films now,
because who knows – they might see someone wearing Jean’s dress.

Britain does not often produce sportsmen who are successful in world championships, but it has been good at inventing sports. In towns and cities space for team sports is limited. To keep fit, most people take part in individual sports. They usually go walking, swimming or cycling. Taking part in all these sports is informal and relaxing. Although many British people want to be healthy not many people do very much about it. A recent study proved that many people were not as active as they thought and incorrectly believed that they did enough exercise to keep fit.
