Answer:

Pentagon: 6.9 in^2

Hexagon: 10.4 in^2

- to the nearest tenth.

Step-by-step explanation:

I am assuming that the pentagon and hexagon are regular.

Area of the pentagon :

Perimeter P = 5 * 2 = 10 inches.

Area = 1/2 * a * P      where a = the apothem

Area = 1/2 * 1.38 * 10

= 6.9 in^2.

Area of the hexagon :

Perimeter P = 6 * 2 = 12 inches.

Area = 1/2 * a * P      where a = the apothem

Area = 1/2 * 1.73 * 12

= 10.38 in^2.

adelina 88 [10]

Answer:

15 miles

Step-by-step explanation:

Let's say the dock is at the origin on a coordinate plane and each unit is 1 mile. If the boat travels 9 mile due north, that means that we move up from the origin (0, 0) 9 units to point A (0, 9). Now, this boat moves 12 miles due west, so we will go 12 units to the left of (0, 9) to point B (-12, 9). See the attached drawing (sorry for the crudeness).

Notice that this is a right triangle with legs of 9 and 12. That means the distance from the boat to the dock is just the hypotenuse, so use the Pythagorean Theorem: distance = \sqrt{9^2+12^2} =\sqrt{81+144} =\sqrt{225} =15

Thus, the answer is 15 miles.

Hope this helps!
