Answer:
450 feet below sea level
Step-by-step explanation:
<em>ascend = move up = add</em>
<em>800 ft below sea level = -800</em>
-800 + 350 = -450

Answer: in the 3 pairs we can find a rational number.
Step-by-step explanation:
A rational number can be any number written as a quotient of two integers.
The rational numbers have a finite number of decimals after the point (or periodic)
a) (-10, -9)
between those two numbers we have, for example, -9.5
and we can write this as:
-9.5 = 95/100
b) (5.91, 5.92)
between these numbers, we have the number 5.915
and we can write it as: 5.915 = 5915/1000
c) (2/3, 4/5)
between 2/3 and 4/5 we have for example the number 3/4.
because 2/3 = 0.66....
4/5 = 0.80
a number between those two is 0.75 = 3/4.
In this situation, the order matters, since being 1st pick is not the same as being 2nd or 3rd. Therefore, there are 14 choices for the first pick, 13 remaining for the second pick, and 12 for the third pick. This is equivalent to the permutation 12P3.

(If order did not matter, this would use a combination.)
