Answer:

Value of boat = $23,400

Loss of value by boat per year = 8%

To find: - Monthly percent decrease in value of boat.

Solution: - Decrease of value per year = 8% of $23,400 = $1,872. Monthly decrease in value = $1,872/12 = $156. Monthly percentage decrease = ($156/$23,400) * 100 = 0.6667 or 0.67 (rounded to nearest hundredth)

Would you say that pythagoras’ theorem holds true for hexagons as well? why or why not

No, the Pythgorean Theorem only applies to right triangles. To get two right triangles, you divide a rectangle diagonally. Dividing a hexagon into two pieces produces trapezoids or pentagons depending where it is divided.
