A swimming pool had 2.5 million liters of water in it. Some water evaporated, and then the pool only had 2 million liters of wat
shepuryov [24]
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%

Create an equation with the indicated number of solutions.
GenaCL600 [577]
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!

The value 191.5638 rounded to the nearest hundredth is<br> 191.564<br> 191.5600<br> 191.56<br> 200
Vesna [10]

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
