Since I do not know the context of the question I will list answers I think it could be based on what you asked:
1. 3.72 x 0.6 = 2.232
2. 3.72 ÷ 0.6 = 6.2

Answers
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:
When light strikes an object, its rays can be either absorbed or reflected. A solid black object absorbs almost all light, while a shiny smooth surface, such as a mirror, reflects almost all light back. When reflected off a flat mirror, light bounces off at an angle equal to the angle it struck the object.

Kevin has these shirts in his closet.
• 3 blue shirts
• 5 red shirts
• 3 purple shirts
• 4 white shirts
Kevin will randomly choose one shirt, not put it back and then choose another shirt. What is the probability that he will choose a red shirt and then a white shirt?
Answers
Since there are a total of 15 shirts,
5 red shirts+4 white shirts= 9 shirts total
3 blue shirts+3 purple shirts= 6 shirts total
The odds that you would pick a red shirt and then a white are 3:2
3 being the 9 red and white shirts combined.
2 being the 6 purple and blue shirts combined.
9:6 simplified=3:2
9/3=3
6/3=2
3:2
Answer: The odds that you would pick a red shirt then a white shirt would be 3:2 or 60%

Given the figure below, find the values of x and z.
Answers
Answer: Z = 83
X = 7
Step-by-step explanation:
Z = 83 because the opposite side is also 83 and they are the same angle. X = 7 because the whole thing equals 360 and 83 +83 = 166 and 360 - 166 = 194 and 194 divided by 2 equals 97 and 15 x 7 - 8 = 97 and the other side is also the same because the angles are the same
