Answer:
Step-by-step explanation:
The direction of movement of Jordan on his birthday forms a right angle triangle. His movement from his house to his parents due south represents the opposite side of the right angle triangle. His movement due west represents the adjacent side and the movement back home along the straight line, d represents the hypotenuse. To determine d, we would apply the Pythagorean theorem. Thus
d² = 6² + 4² = 52
d = √52 = 7.2 km
The total distance that he drove on his birthday is
6 + 4 + 7.2 = 17.2 km

Answer:
D S = (1 - 0.2)g
Step-by-step explanation:
The original price of the guitar was g.
She paid 0.8g.
0.8g = 0.80g = 80% of g
If she paid 80% of the price, that means the discount was 20%.
100% - 20% = 1 - 0.2
Subtracting 20% form the whole 100% of the price is the same as subtracting 0.2 from the whole price of 1.
Answer: D S = (1 - 0.2)g
