Timing:
00:00:00 - introduction. Seryozha is vacationing with his dad in the village of Pirozhki in the summer. On Wednesday they are going to go by car to the village of Knyazheskoye. You can drive from the village of Pirozhki to the village of Knyazheskoye along a straight dirt road. There is a longer route: along a straight highway through the village of Vasilyevo to the village of Ryabinovka, where you need to turn left at a right angle onto another highway leading to the village of Knyazheskoye. There is also a third route: in the village of Vasilyevo, you can turn onto a straight dirt road to the village of Knyazheskoye, which goes past the pond.
The highway and dirt roads form right triangles.

00:07:28 - 10. There are identical-looking pies on a plate: 13 with meat, 11 with cabbage and 6 with cherries. Anton takes one pie at random. Find the probability that the pie will be with cherries.
00:07:54 - 11. The figures show the graphs of functions of the form y=kx+b. Establish a correspondence between the signs of the coefficients k and b and the graphs of the functions.
00:08:36 - 12. At the "Eh, Prokachu!" company The cost of a taxi ride (in rubles) lasting more than 5 minutes is calculated using the formula C = 170 + 15 (t - 5), where t is the duration of the ride (in minutes). Using this formula, calculate the cost of a 14-minute ride. Give your answer in rubles.
00:09:02 - 13. Indicate the solution to the inequality 5x - x ^ 2 is greater than 0
00:09:56 - 14. Yana has a bouncy ball (a rubber ball). She threw it on the asphalt with all her might. After the first bounce, the bouncy ball flew up to a height of 240 cm, and after each subsequent bounce from the asphalt, it flew up to a height half that of the previous one. After how many bounces will the height to which the bouncy ball flies up become less than 5 cm?
