Question

Розовые кусты, которые выкрасили в красный цвет в саду Червонной королевы, распространяют свой запах в радиусе 28 м вокруг себя каждый. Сколько минимально таких кустов потребуется посадить вдоль прямолинейной аллеи длиной 315 м, чтобы в каждой её точке был аромат роз? Ответ:[ ]шт. ПОМОГИТЕ ПЖ​

Answer 1

Ответ:

в сумме 1 куст распространяет запах на 46 м так 28 с одной и 28 с другой и делишься 350 на 46 наверно

Answer 2

To determine the minimum number of pink bushes needed to ensure that the scent of roses is present at every point along a straight alley that is 315 meters long, we need to calculate the spacing between the bushes.

Let's assume that each bush can spread its scent in a radius of 28 meters. This means that the scent from each bush will cover a circular area with a diameter of 56 meters (28 meters radius * 2).

To ensure that the scent from one bush overlaps with the scent from the next bush, we can place the bushes in a staggered pattern. In this pattern, the center of each bush will be located at the edge of the circular area created by the previous bush.

To calculate the spacing between the bushes, we need to subtract the diameter of each circular area from the total length of the alley. In this case, the diameter is 56 meters, so the spacing between the bushes will be 315 meters - 56 meters = 259 meters.

To determine the number of bushes needed, we divide the length of the alley by the spacing between the bushes:

315 meters / 259 meters ≈ 1.22

Since we can't have a fraction of a bush, we need to round up to the nearest whole number. Therefore, the minimum number of pink bushes required to ensure that the scent of roses is present at every point along the 315-meter alley is 2 bushes.

Please note that this calculation assumes ideal conditions and uniform distribution of scent. Factors such as wind direction and strength, as well as the intensity of the scent, may affect the actual coverage area.
