7.8 miles ( to 1 dec. place )

Step-by-step explanation:

The horizontal distance = 10 - 4 = 6 ← difference in x-coordinates

The vertical distance = 8 - 3 = 5 ← difference in y-coordinates

Consider the right triangle with legs 6 and 5 and calculate the hypotenuse (d) the distance between house and gas station using Pythagoras' identity, that is

d² = 6² + 5² = 36 + 25 = 61

Take the square root of both sides

d = ≈ 7.8 miles

The distance between house and gas station is 7.8 miles

b) the dogs need to shift their focus to human scent.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
