The elevation of the trench is between 4 miles and 5 miles.
<h3>Between which integers is the elevation of the trench in miles?</h3>
Herein we have the information of the elevation of the trench in feet and we need to determine between which integers in miles is that elevation, based on the unit conversion from feet to miles. The exact elevation in miles is found by simple rules of three:
x = 22,889 feet × (1 / 5,280 miles / feet)
x ≈ 4.335 miles
The elevation of the trench is between 4 miles and 5 miles.

The last guy's height is 69 inches
Step-by-step explanation:
mean=sum of all numbers/number of numbers
There are 5 numbers in the set which means that 65 is the sum of all five numbers divided by 5. To reverse that we multiply 65 by 5 to get the sum of all of the numbers.

325 is the sum of all of the numbers so to find the missing number you add up all of the known numbers in the set and find the difference between that sum and 325.


The missing guy's height is 69 inches.
