Answer:
The life of Black soldiers was very hard as they have to face racism in the army units.
Step-by-step explanation:
Although the life of soldiers during the civil war was not easy, now imagine the black soldiers who were fighting many wars every day. The emancipation proclamation by Linclon allowed blacks to join the Union army. Following the outbreak of the Civil War, abolitionists such as Frederick Douglass argued that enlisting black soldiers would aid the North to win the war. But Balck soldiers faced discrimination in the army camps. They received lower pay than their white counterparts. Most Union officers believed that black soldiers were not as qualified or as courageous as white soldiers.
v=bh therefore v=(212)(112)
So the volume would be 23744 cm^3
Part A:
The area of the rectangle will be the length times the width, so 4•(x+3). Using distributive property, you'll multiply every term inside the parentheses by 4.
The area of the rectangle can be expressed by 4x+12.
Part B:
Multiply 4•2 and (x+3)•2, then multiply them together.
8(2x+6) Now use distributive property to find your answer simplified.
16x+48 is your answer
Angles are formed by intersection of non-collinear lines, rays and planes.
<u />
<u>Part A</u>
<u>1. Contradictory Example</u>
A contradictory example to the given definition is that:
When the rays are collinear; the rays do not form an angle, but they form a line
<u />
<u>2. A more accurate definition</u>
A more accurate definition is that:
An angle is formed at the intersection of two non-collinear rays that have the same endpoint
<u />
<u>Part B</u>
<u>Example of an undefined term</u>
Undefined terms do not have a formal definition; an example is the plane.
A plane pertains to angles because it determines the parameter to be measured.

14) The horizontal distance when the plane is at 500 ft. is 2358.5 ft.
15) The length of the wire is 44.7 ft.
<u>Step-by-step explanation:</u>
14) Let the horizontal distance be 'd'
the height of the plane = 500 ft.
Angle of elevation= 12°
tan 12° = 500/d
d = 500/tan12°
d = 500/0.212
d = 2358.5 foot
The horizontal distance when the plane is at 500 ft. is 2358.5 ft.
15) Let the length of the wire be 'n'
The height of the pole = 30ft.
Angle formed between pole and wire = 48°
Cos 48° = 30/n
n = 30/cos 48°
n = 30/ 0.67
n = 44.7 ft.
The length of the wire is 44.7 ft.
