I think summer is the best season of all because it is warm, the nature is beautiful and we have great opportunities for rest. Summer is a time of holidays. We can go anywhere, spend our time near a river or a lake on fresh, green grass, swim in warm water, or climb mountains, play different games, ride a bicycle and so on.I spend my summer holidays at my granny’s. There are many things there to do. What I did most of the time - I swam in the sea and sunbathed. Sometimes I made a fire with my friends at the seaside and cooked potatoes there. It was wonderful. We told anecdotes to each other, and did everything we wanted. I also got used to walk alone in the forest.When August was coming to its end, I went on a small voyage by ship. The ship name was “Sevastopol”.But this summer wasn’t for me only sugar and honey. I have passed through the graduating exams after school and entering exams in the university. So the bigger part of my summer vacations I spent sitting with the books. Of course, it was not interesting, but I’m glad that I did it because now I’m a student of the best university in our country.
1 полный круг на часовом циферблате = 12 часам. Часовая стрелка за 1 час проходит 1/12 часть полного круга. Минутная стрелка за 1 час делает полный круг, то есть 12/12 полного круга. 12/12-1/12=11/12 - минутная стрелка проходит больше часовой за 1 час на 11/12 полного круга. 11/12 : 1/12=11/12*12/11=11 - минутная стрелка быстрее часовой в 11 раз Часовая стрелка проходит за 24 часа 2 полных круга. Минутная стрелка проходит за 24 часа 2*11=22 полных круга, значит и обоняет часовую стрелку 22 раза. ответ: 22 раза
a=48 дм
b=16 дм
c=12 дм
V-?
V=abc
V=48*16*12=9216 (куб.дм)
ответ: объём параллелепипеда 9216 кубических дециметров.
