Answer: The rancher will use 8527 milliliters to fill both the bowl and the trough.
Step-by-step explanation:
Since we have given that
Quantity of water bowl for her dog = 8500 milliliters
Quantity of water trough for her horse = 27 milliliters
Total quantity of water that the rancher will used to completely fill both the bowl and the trough is given by

Hence, the rancher will use 8527 milliliters to fill both the bowl and the trough.
X is 30 because we can minus 60on both sides and add 3x on both sides to find the answer
Answer:
or 
(see explanation)
Step-by-step explanation:
This problem is asking about compound probability, what is the probability of this even happening three times in a row.
Since there are 20 boy's names and 20 girl's names in the hat, one can say that half of the names in the hat. Assume that after drawing it from the hat, the name is put back into the hat. Therefore, on each night, there is a half-chance of the event happening. To find the probability of the event, one must multiply (
) by itself (3) times,

In this case, assume that after each drawing the name is not replaced into the hat. This means that after every draw, one must subtract (1) from both the numerator and denominator of the fraction when the fraction is in the un-simplified form.

Simplify,
