Здравствуйте! Мне нужно сделать 2 номера. Надеюсь вы поможете! №1305 (2) 2 часа+15 минут+30 минут+1 час 45 минут+12 минут=..... №1292 Пакет может выдержать не больше 4,7 килограмм груза.Можно ли положить в него: 1) 0,75 килограмм конфет, 2,5 килограмм яблок и 1,8 килограмм колбасы? 2)0,67 килограмм мармелада, 2,13 килограмм груш и 1,5 килограмм колбасы?

Answer 1

1) 4 часа 42 мин.=4,7
2) 0,75 +2,5 +1, 8=5,05 - не выдержит пакет
     0,67 +2,13 + 1,5 =4,3 - выдержит

Answer 2

1) 120+15+30+60+45+12=282 в десятичных хз)
2)нет
3)можно

Answer 3

Calculation of Time

To calculate the total time for the first number, we add up the given durations: - 2 hours 15 minutes - 30 minutes - 1 hour 45 minutes - 12 minutes

To perform the calculation, we convert all the durations to minutes and then add them together.

2 hours 15 minutes = 2 * 60 + 15 = 135 minutes 30 minutes = 30 minutes 1 hour 45 minutes = 1 * 60 + 45 = 105 minutes 12 minutes = 12 minutes

Adding all the durations together: 135 minutes + 30 minutes + 105 minutes + 12 minutes = 282 minutes.

Therefore, the total time for the first number is 282 minutes.

Calculation of Weight

To determine if the given items can fit into the package, we need to calculate the total weight of the items and compare it to the maximum weight the package can hold.

For the first scenario: - 0.75 kilograms of candy - 2.5 kilograms of apples - 1.8 kilograms of sausage

Adding up the weights: 0.75 kilograms + 2.5 kilograms + 1.8 kilograms = 5.05 kilograms.

The total weight of the items is 5.05 kilograms.

For the second scenario: - 0.67 kilograms of marmalade - 2.13 kilograms of pears - 1.5 kilograms of sausage

Adding up the weights: 0.67 kilograms + 2.13 kilograms + 1.5 kilograms = 4.3 kilograms.

The total weight of the items is 4.3 kilograms.

Comparing the total weights to the maximum weight the package can hold: - The maximum weight the package can hold is 4.7 kilograms. - In the first scenario, the total weight of the items is 5.05 kilograms, which exceeds the maximum weight. Therefore, the items cannot fit into the package. - In the second scenario, the total weight of the items is 4.3 kilograms, which is less than the maximum weight. Therefore, the items can fit into the package.

To summarize: 1) The items in the first scenario cannot fit into the package. 2) The items in the second scenario can fit into the package.

Please note that the calculations provided are based on the information given and assume that the weights and durations are accurate.
