На олимпиаде по математике действуют следующие правила: за каждую верно решенную задачу выдаются еще 4 задачи; если задача решена неверно, второй раз ее решать нельзя. В начале олимпиады Витя получил 9 задач, а всего за олимпиаду решал (возможно, неверно) 113 задач. Сколько задач Витя решил верно? НЕ уравнением

Ответы

Автор ответа: МишкиРулят

1) найдём сколько задач дали Вите дополнительно:
113-9=104
2) и поделив полученное число на 4, узнаем сколько из этих задач Витя решил верно
104/4=26
Значит Витя решил 26 задач верно

WHAT IS BIOLOGY? Biology is the study of life and living organisms. For as long as people have looked at the world around them, people have studied biology. Even in the days before recorded history, people knew and passed on information about plants and animals. Modern biology really began in the 17 th century. At that time, Anton van Leeuwenhoek, in Holland, invented the microscope and William Harvey, in England, described the circulation of blood. The microscope allowed scientists to discover bacteria, leading to an understanding of the causes of disease, while new knowledge about how the human body works allowed others to find more effective ways of treating illnesses. All these new knowledge needed to be put into order and in the 18 th century the Swedish scientist Carl Linnaeus classified all living things into the biological families we know and use today. In the middle of the 19 th century, unnoticed by anyone else, the Austrian monk Gregor Mendel, created his Laws of Inheritance, beginning the study of genetics that is such an important part of biology today. At the same time, while traveling around the world, Charles Darwin was formulating the central principle of modern biology – natural selection as the bases of evolution. In the 20 th century biologists began to recognize how plants and animals live and pass on their genetically coded information to the next generation. Since then, partly because of developments in computer technology, there have been great advances in the field of biology; it is an area of ever-growing knowledge. During the past few hundred years biology has changed from concentrating on the structure of living organisms to looking more at how they work or function. Over this time biologists have discovered much about health and disease, about the genes which control the activities of our bodies and how humans can control the lives of other organisms. We need to understand how our activities affect the environment, how humans can take responsibility for their own health and welfare and how we must be careful to make appropriate rules for the use of our genetic information. Nowadays biologists are making fantastic discoveries which will affect all our lives. These discoveries have given us the power to shape our own evolution and to determine the type of world we will live in. Recent advances, especially in genetic engineering, have dramatically affected agriculture, medicine, veterinary science, and industry, and our world view has been revolutionized by modern developments in ecology. There has never been a more exciting nor a more important time to study biology.
