Answer as an improper fraction = 16/5
Answer as a mixed number = 3 & 1/5
Answer in decimal form = 3.2
All of those values represent the same thing, but written in a different way.
=============================================================
Explanation:
I'm assuming HM stands for Harmonic Mean in this case.
If so, then we apply the reciprocal operation to each value to get 1/2 and 1/8 (from 2 and 8 respectively).
Add up those fractions:
1/2 + 1/8 = 4/8 + 1/8 = 5/8
Now we'll divide n = 2 over that result. The n = 2 refers to the number of items in the original set.
n divide over (5/8) = 2*(8/5) = 16/5 which is the answer as an improper fraction

To convert to a mixed number, we can do the following:
16/5 = (15+1)/5
16/5 = 15/5 + 1/5
16/5 = 3 + 1/5
16/5 = 3 & 1/5
Or if you need the answer in decimal form, then using a calculator would get you 16/5 = 3.2
5 + 8 = 13
169/13 = 13
13 * 5 = 65
13 * 8 = 104
Thus, 65:104
Answer:it is neither accurate nor precise
Step-by-step explanation:
You can use pythagorean theorem. 3 miles would be one leg and 2 miles would be the other. (We’ll just call these two a and b in the formula. Letter c, also known as your hypotenuse, will be this ‘straight line distance’.) In order to find this you’ll use: a^2 + b^2 = c^2
Then you’ll find the square root of your sum to get the answer.
Answer: 3^2 + 2^2 = ?
9 + 4 = 13
the square root of thirteen will be about
