Answer:
48
Step-by-step explanation:
Let n represent the number. "The quotient of a number and 4" is represented by (n/4). To represent decreasing that value by 10, we write ...
(n/4) -10
We are told this "is two":
(n/4) -10 = 2
n/4 = 12 . . . . . . . add 10
n = 48 . . . . . . . . multiply by 4
The number is 48.
Answer: The value of absorbance is 0.3010
Step-by-step explanation:
Transmittance,(T)= 50%
Absorbance, (A)= ?

Transmittance and absorbance are inversely related:

Hence,the value of absorbance is 0.3010 when transmittance was 50%.
From my understanding -4/5 is bigger.
Answer:
The migration of the African-Americans to Harlem in the USA empowered the African-Americans in the society in the early 1900s. This was one of the greatest accomplishments of the African-Americans in history.
Explanation:
The "Harlem Renaissance" was originally called the "New Negro Movement." During the "Reconstruction Era," many of the African Americans felt a newfound empowerment in the society. They started leaving the South, where most of them were enslaved and maltreated. Many of them moved to other places such as "Harlem" in New York City. It became an ideal destination for many "Negros" and their number increased over time.<u> This then became an African-American neighborhood</u>.
African-Americans started producing plays with actors of their descent. Several Negro poets emerged describing the life of the African-Americans. Negros became more literate and able when it comes to expressing themselves in the society. They even had their own newspaper known as<em> "The New Negro Movement."</em>
