Question

Вихід чаю із сухого чайного листу становить 4,5%. 1)Скільки чаю одержимо,якщо висушити 800 кг чайного листку? 2)Скільки кілограмів чайного листу потрібно висушити, щоб одержати 20,7 кг чаю?

Answer 1

Ответ:

Пошаговое объяснение:

4,5% = 4,5 : 100 = 0,045

1) 800 * 0,045 = 36 (кг) - получим чая

2) 20,7 : 0,045 = 460 (кг) - потребуется чайного листа

Answer 2

Calculation of Tea Yield from Dried Tea Leaves

To calculate the amount of tea obtained from dried tea leaves, we need to know the percentage of tea yield from dry tea leaves. In this case, the tea yield from dry tea leaves is stated to be 4.5%.

1) How much tea can be obtained by drying 800 kg of tea leaves?

To calculate the amount of tea obtained, we can multiply the weight of the tea leaves by the percentage of tea yield:

Tea obtained = Weight of tea leaves * Tea yield percentage

Substituting the given values:

Tea obtained = 800 kg * 4.5% = 36 kg

Therefore, if 800 kg of tea leaves are dried, approximately 36 kg of tea can be obtained.

2) How many kilograms of tea leaves need to be dried to obtain 20.7 kg of tea?

To calculate the weight of tea leaves needed, we can rearrange the formula:

Weight of tea leaves = Tea obtained / Tea yield percentage

Substituting the given values:

Weight of tea leaves = 20.7 kg / 4.5% = 460 kg

Therefore, approximately 460 kg of tea leaves need to be dried to obtain 20.7 kg of tea.

Please note that these calculations are based on the given tea yield percentage of 4.5%.
