Hello keirabug, I am here to answer your question:
Since 10^3 is the same as 10*10*10, or 1000, and each CD is worth 12$, then 1000 * 12$ is equal to 12000$
But for the CD players, it's 10^2 or 10*10, which gives us 100, and each CD player is worth 35$, so 100 * 35$ is equal to 3500$
And then we do an addition to add the prices like this: 12000$ + 3500$ = 15500$
So the answer is 15500$
Hope this helped you!
Answer:
the answer is nonagon
A nonagon is a polygon made up of 9 sides and 9 angles.
A. (Number of sides - 2) x 100, so
6-2= 4 x 180
= 720° is the sum of all angles in a hexagon
84 + 87 + 128 + 150 + 103 = 552
720 - 552 = 168
X = 168°
2. Angles in a triangle sum up to 180°
36 + 57= 93
180 - 93 = 87
A= 87°
