Answer:
12
Step-by-step explanation:
Lets c = chord inside circle
3(3 + c) = 6^2
9 + 3c = 36
3c = 27
c = 9
x = 3 + 9
x = 12
Answer:
the opposite of what is in the parentheses so -(-6) would just be 6
Answer:
Given:
I usually walk from home to work. This morning, I walked for 10 minutes until I was halfway to work.
I then realized that I would be late if I kept walking.
I ran the rest of the way. I run twice as fast as I walk.
Find:
The number of minutes in total did it take me to get from home to work
Step-by-step explanation:
Had I kept walking, the second half of my trip would have taken 10 more minutes.
By doubling my speed for the second half of my trip,
I halved the amount of time it took me to finish.
So, the second half of my trip took 5 minutes, for a total trip time of 10+5 = 15 minutes.
The number of minutes in total did it take me to get from home to work is 15 minutes.

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.
