Answer: $160
Step-by-step explanation:
80%is the same thing as 
Also , since we are using equivalent ratio , we will look for a way to write 200 in order to have equivalent of 100. That is 200 is the same as 100 x 2
Therefore : 80% of a 200 is the same
x 100 x 2
which is the same as 80 x 2
$160
We will calculate the length of the hypotenuse using the Pythagorean theorem. Suppose that the hypotenuse = c, then:
c^2 = 6^2 + 3^2
c^2 = 36 + 9
c^2 = 45
c = square root of 45
c = square root of 9 * square root of 5
c = 3 * square root of 5 ; <em>square root of 5 = approximately 2,24</em>
c = 3 * 2,24 = 6,72 = 6,7
The correct answer is 6,7.
