The first one, SAS Postulate
Hi!
We are given the information found in the picture below.
Note: The directions aren't correct, but the triangle works for this problem.
The "direct path" is the hypotenuse of this triangle.
To find this, we use the Pythagorean Theorem, where
and
are 2 legs of the triangle, and
is the hypotenuse, aka the longest side of any triangle:

We know
and
and want 



Therefore,
is approximately 
Since we are converting meters to centimeters we are converting large to small.
Expect the answer to be a larger number. Here are some example of large to small:
2 weeks (larger unit) = 14 days (smaller unit) 14 is larger than 2
4 days (larger unit ) = 96 hours (smaller unit) 96 is larger than 4
Since there are 100cm in a meter, when we change meters to cm, we need a bigger number. The conversion factor is 100 and should be used as a multiplier.
Example: 47m x 100 = 4700 cm
Answer:
$0.88
Step-by-step explanation:
cost per 1% = 22 ÷ 100 = 0.22
⇒ cost of 4% = 4 x 0.22 = 0.88
Or
4% = 4/100 = 0.04
⇒ 4% of 22 = 0.04 x 22 = 0.88
