Question

Денис хотел записать на кассету мультфильмы, показ которых длился 46 минут, 48 минут, 26 минут, 54 минуты, 32 минуты. Поместятся ли все они на 180-минутной кассете? Какие мультфильмы выгоднее записать, чтобы оставалось меньше свободного места?

Answer 1

1) 46+48+26+54+32= 206
206>180 места не хватает
Самое выгодное это записать все мутфильмы, кроме 26- минутного

Answer 2

Can all the cartoons fit on a 180-minute cassette?

To determine if all the cartoons can fit on a 180-minute cassette, we need to calculate the total duration of the cartoons and compare it to the available recording time.

The duration of the cartoons are as follows: - Cartoon 1: 46 minutes - Cartoon 2: 48 minutes - Cartoon 3: 26 minutes - Cartoon 4: 54 minutes - Cartoon 5: 32 minutes

To find the total duration, we add up the durations of all the cartoons: 46 + 48 + 26 + 54 + 32 = 206 minutes

The total duration of the cartoons is 206 minutes, which exceeds the available recording time of 180 minutes. Therefore, all the cartoons cannot fit on a 180-minute cassette.

Which cartoons should be recorded to minimize the remaining free space?

To minimize the remaining free space on the 180-minute cassette, we need to select the cartoons with the shortest durations.

The cartoons with the shortest durations are: 1. Cartoon 3: 26 minutes 2. Cartoon 5: 32 minutes

By recording Cartoon 3 (26 minutes) and Cartoon 5 (32 minutes), we would use a total of 58 minutes of the available recording time. This would leave 180 - 58 = 122 minutes of free space on the cassette.

Therefore, to minimize the remaining free space, it is recommended to record Cartoon 3 and Cartoon 5.

Note: It is important to note that the specific titles of the cartoons are not provided in the question, so we can only refer to them as Cartoon 1, Cartoon 2, etc.
