Question

На сколько нужно увеличить количество оставшейся в баке воды,чтобы получить прежнее количество после испарения 30% воды

Answer 1

(1-0.3)*(1+0.01x)=1
0.7*(1+0.01x)=1 0.7+0,007x=1 0.007x=1-0.7 0.007x=0.3 x=0.3/0.007 x=42,(857142)%

Answer 2

Calculating Increase in Water Volume to Compensate for Evaporation

To calculate the increase in the remaining water volume needed to restore the original amount after 30% evaporation, we can use the following formula:

New Volume = Original Volume / (1 - Evaporation Rate)

Where: - Original Volume is the initial amount of water in the tank. - Evaporation Rate is the proportion of water that has evaporated, expressed as a decimal (e.g., 30% = 0.3).

Applying the Formula

Let's assume the original volume of water in the tank is 100 units. Using the formula, we can calculate the new volume required to compensate for the 30% evaporation:

New Volume = 100 / (1 - 0.3) New Volume = 100 / 0.7 New Volume ≈ 142.86

So, to restore the original volume of water after 30% evaporation, approximately 142.86 units of water are needed.

Conclusion

To compensate for a 30% evaporation of water in the tank, the remaining water volume needs to be increased by approximately 42.86% to restore the original amount.
