City Park is in the shape of a regular pentagon.Each side of the pentagon is 2/5 mile long.What is the perimeter of City Park?

Answers

Answer 1
Answer: so you have 5 sides you can add 2/5+2/5+2/5+2/5+2/5 = 10/5 = 2 miles around the park. Or you can multiply 5 sides (pentagon) times each side of 2/5 mile thus..... 5*2/5 = 10/5 = 2 so this is also 2 miles around the perimeter.

The commutative property does not work which operations

Answers

Answer:

Addition and multiplication are both commutative. Subtraction, division, and composition of functions are not. For example, 5 + 6 = 6 + 5 but 5 – 6 ≠ 6 – 5. More: Commutativity isn't just a property of an operation alone.

Find the exact length of the third side

Answers

Answer: 3 times the square root of 5! (Or the square root of 45 if you don’t want to simplify)

Step-by-step explanation:

First, you would need to use the Pythagorean Theorum, a^2 + b^2 = c^2, since it is a right triangle.

So in this case,

6^2 + 3^2 = c^2

This simplfys to:

36 + 9 = c^2

45 = c^2

Now you have to take out the square in the c. What you do to one side, you have to do to the other, so you have to put 45 in a square root. This simplies to 3 times the square root of 5.
