80 inches in standard notation using feet and inches would be expressed as 6 ft 8 inches by converting inches into feet and inches.
The solution to the given problem is to use some standard conversion units that are:
- 1 foot = 12 inches
- 1 inch = 0.8333 feet
Solution:
As mentioned above that one inch is equal to 0.8333 foot therefore
1 foot = 12 inches
then,
80 inches would be equal to
= ft
= ft
= 6ft 8 inches
= 6' 8"
Thus, 80 inches in standard notation using feet and inches would be expressed as 6 ft 8 inches by converting inches into feet and inches.

Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.
If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).
Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.
c^2 = a^2 + b^2
where c is the total displacement from the starting point to the end point
a is the distance he walks up north
b is the distance he walks to the west
c^2 = 100^2 + 100^2
c^2 = 10,000 + 10,000
c^2 = 20,000
c = 141.42 meters
Comparing the total distance the student walked and the total displacement from the starting point to the end point by subtraction.
100 meters + 100 meters - 141.42 meters = 53.58 meters
