225:15=15

Автор ответа: Sark2002

5 длинных деталей - это 5*25 см=125 см.

значит остальная длина = 3 м 50 см(350 см)-125=225 см.

В итоге коротких деталей - 225/15=15.

Task 2
Read the text below. Match choices (A-G) to (6-10). There are two choices you do not need to use.
THE LEGEND OF SLEEPY HOLLOW
The valley known as Sleepy Hollow hides from the world in the high hills of New York State. A small river
runs its clear water through the valley, and the only sounds ever heard are those of a lost bird looking for its home
in the hills.
7
There are many stories told about the quiet valley, but the story that people believe most is about a man who
rides a horse at night. The story says the man died many years ago during the American Revolutionary War. His
head was shot off. And every night he rises from his burial place, jumps on his horse, and rides through the valley
looking for his lost head.
8
Near Sleepy Hollow is a village called Tarry Town. It was settled many years ago by people from Holland.
The village had a small school and one teacher named Ichabod Crane. Ichabod Crane was a good name for him
because he looked like a crane. He was tall and thin like a crane bird. His shoulders were small, joined to long
arms. His head was small, too, and flat on top. He had big cars, large glassy green eyes, and a long nose.
Ichabod did not make much money as a teacher. He was tall and thin, it is true, but he ate like a fat man. To
help him pay for his food, he earned extra money teaching young people to sing. Every Sunday after church
Ichabod taught singing.
9
Among the ladies Ichabod taught was one, Katrina Van Tassel. She was the only daughter of a rich Dutch
farmer. She was a girl in bloom much like a round rosy-red apple. Ichabod had a soft and foolish heart for the
ladies, and soon found himself interested in Miss Van Tassel.
10
Ichabod's eyes opened wide when he saw the riches of Katrina's farm-the miles of apple trees and wheat
fields and hundreds of fat farm animals. He saw himself as master of the Van Tassel farm, with Katrina as his wife.
