Відповідь:

Піску взяли у 2,4 рази більше, ніж цементу.

Покрокове пояснення:

Для приготування будівельної суміші взяли 19 кг піску, а цементу – на 11 кг менше, тобто:

19 - 11 = 8 кг.

Таким чином піску взяли у 19 / 8 = 2 3/8 = 2,375 разів більше ніж цементу.

З наближенням до десятих отримаємо 2,4 рази.

Установите соответствие между текстами А-G и заголовками 1-8. Занесите свои ответы в таблицу. Используйте каждую цифру только один раз. В задании один заголовок лишний.

1. New technologies and music
2. Continuous success
3. The kings of rock
4. Fruit of collaboration
5. In Search of Perfection
6. Individual and collective mastery
7. Dedication is contagious
8. The lived experience put into the notes

A. The rock musicians of the sixties still refuse to become a shadow of the past and try to offer something new to the public. This is the case of the legendary Deep Purple, who reappeared with a single concert in Europe and an album of new compositions. However, their participation in the "Musicians in Nature" festival together with modern musicians is a good pretext to talk about the future of music.

B. As long as musicians find a way and a place to give concerts, they will survive, because people like to escape from their offices and computers and listen to something different live. But the internet is changing everything. It's made so that no one makes a profit from a record. People go out to be entertained, but they can do it on TV or YouTube. At the concert there is a very special atmosphere and a very intimate relationship between the musician and their listeners.

C. To prepare the new album they tried to keep the band together for a long time, they did everything together. They were encouraged to bring ideas and incomplete songs to the studio, discussing everything. It was hard work, before they started recording they came in every day with a number of ideas to show them and they never had enough time. The effects on the organs, guitar attacks, make this a definitive treatment of the album and their most impressive album.

D. As for inspiration, these musicians write songs about their experiences. There is truth in everything they do. They present notes about the world, and they have known a lot, throughout their 40+ years of life, the band has travelled multiple paths in their journey, this is very interesting for a guitarist. They are classics, as they are a fundamental part of rock history. But you have to remember that at the same time they play for very young people.

E. Improvisation is the only thing that allows you not to have a perfect show but to keep looking for it, to try to play better. Based on something that is already written, you can challenge yourself to do it one hundred percent. On the other hand, in the improvisation sections you stay much more instinctive in front of the instrument, which allows you to stay away from the risk of going out to play for show or to pose. They try to improvise in a way that works for most of the solos.

F. Some people say that it's worth going to a rock concert as much for the band as for the guitar solos. As if they were two different shows. The truth is that leading the band and having a solo section is very good for a musician, but it's not the main power in rock. It's working with other people, making the band work. It's like I have a remote control and I can press it with certain songs and the whole place starts dancing.

G. Famous musicians inspire millions of teenagers to pick up the guitar for the first time. Many of them tend to think that the guitar is an easy way to make their way in life, but that is not true. When choosing the guitar, you have to dedicate all your free time to it and be very firm in your decision, but at the same time keep playing without stress, live it and enjoy it like one who learns another language, in this case that of music.
