Answer:
calcium and gold
Step-by-step explanation:
Answer:8.76712328...%
Step-by-step explanation:
1.Find the increase in students. 397-365=32
2. Take the ratio and put it into percent. 32/365=x/100
3. Cross multiply. 32 x 100=365x
4.Solve. X=8.76712328...%
It is repeating forever like this.
8.767123287671232876712328
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
