Question

Пожалуйста! Помогите! Срочно надо! Масса сушеных яблок составляет 25% массы свежих.Сколько сушеных яблок получили из 200кг;360кг;4,5т свежих? Сколько % массы свежих яблок теряется при сушке?(решение и ответ)

Answer 1

Второй вопрос не поняла, но подозревая что 75%

Answer 2

1. 200*25/100=50 кг 
2. 360*25/100= 90кг
3. 4500*25/100=1125 кг
4. 100-25=75% теряется

Answer 3

Calculation of Dried Apples

To calculate the amount of dried apples obtained from a given weight of fresh apples, we need to consider that the mass of dried apples is 25% of the mass of fresh apples.

Let's calculate the amount of dried apples obtained from different weights of fresh apples:

1. For 200 kg of fresh apples: - Mass of dried apples = 25% of 200 kg = 50 kg.

2. For 360 kg of fresh apples: - Mass of dried apples = 25% of 360 kg = 90 kg.

3. For 4.5 tons (4,500 kg) of fresh apples: - Mass of dried apples = 25% of 4,500 kg = 1,125 kg.

Percentage of Mass Lost during Drying

To calculate the percentage of mass lost during the drying process, we need to find the difference between the mass of fresh apples and the mass of dried apples, and then calculate the percentage of this difference relative to the mass of fresh apples.

Let's calculate the percentage of mass lost during drying:

1. For 200 kg of fresh apples: - Mass lost during drying = 200 kg - 50 kg = 150 kg. - Percentage of mass lost = (150 kg / 200 kg) * 100% = 75%.

2. For 360 kg of fresh apples: - Mass lost during drying = 360 kg - 90 kg = 270 kg. - Percentage of mass lost = (270 kg / 360 kg) * 100% = 75%.

3. For 4.5 tons (4,500 kg) of fresh apples: - Mass lost during drying = 4,500 kg - 1,125 kg = 3,375 kg. - Percentage of mass lost = (3,375 kg / 4,500 kg) * 100% = 75%.

Therefore, the percentage of mass lost during the drying process is 75% for all the given weights of fresh apples.
