Answer:
Exact form: d=75/2
decimal form: d=37.5
mixed number form: d=37 1/2
Step-by-step explanation:
20,000 * .05 = 1,000 1,000 * 3 = 3,000 20,000 + 3,000 = 23,000 Hope This helps :)
The answer is 2942.10 because 2,949.7-7.6= 2942.10
Answer:
B. High optical density, and light travels more slowly through it.
Step-by-step explanation:
Refractive index is the property of a material that describes the change in the initial path of light and the rate at which light travels through it. And optical density of a material describes its absorption ability to rays or beam of light passing through it.
As the index of refraction of a material increases, therefore its optical density would increase. This would cause light to travel through it slowly. Unless the light has a high frequency.
A material with a high index of refraction has a high optical density, and light travels more slowly through it.
