Step-by-step explanation:
- Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection. For a rough surface, reflected light rays scatter in all directions.
Answer: $2200
Step-by-step explanation:
20% = 0.2
2750 x 0.2 = 550
2750 - 550 = 2200
OR
2750 x (1-0.2) =
2750 x (0.8) = 2200
The factor that is the first one is the most important
Answer:
B
Step-by-step explanation:
Since both angles together need to equal 180, set up your formula as
(x+30)+(x+10)=180
2x+40=180
