Answer:
no entiendo
Step-by-step explanation:
Original volume = 2.5 million liters.
After evaporation, the remaining volume is 2 million liters, therefore
Evaporated volume = 2.5 - 2 = 0.5 million liters.
Percent of water evaporated = 100*(0.5/2.5) = 20%
Answer: 20%
An equation that doesn't have a solution would have to end up as something impossible when you solve it all out, like
5=3.
When you simplify your equation out, you get
3x-4=3x+?
Subtract 3x from both sides.
-4=?
From this, you can tell that you need to out something in the ? that will make the equation false, or something that doesn't equal -4.
You could put anything in the ? as long as it is not -4.
Hope this helps!
Answer:
191.56
Step-by-step explanation:
Given
191.5638
Required
Approximate
Approximating to the nearest hundredth implies that, only to digits after the decimal point is needed
This is:
191._ _
The third digit after the decimal point will approximated using the approximation rule;
Since, the third digit after the decimal point (3) is not up to 5, it'll be approximated to 0 and added to the second digit (6)
So, we have:
191.5 _
The next digit is calculated as 6 + 0 = 6
Hence, the full approximated number is 191.56
