World War II was one of the most significant events of the 1900s and one of the most important events in US history. Think about how much the United States changed between the Great Depression and the postwar era, when the country had become an economic powerhouse. How did World War II influence and change the identity of the United States throughout the 1900s and into the present? What are some positive and negative changes that occurred in the United States in the years after World War II​

Answers

Answer:

America's involvement in World War II had a significant impact on the economy and workforce of the United States. The United States was still recovering from the impact of the Great Depression and the unemployment rate was hovering around 25%. Our involvement in the war soon changed that rate. American factories were retooled to produce goods to support the war effort and almost overnight the unemployment rate dropped to around 10%. As more men were sent away to fight, women were hired to take over their positions on the assembly lines. Before World War II, women had generally been discouraged from working outside the home. Now, they were being encouraged to take over jobs that had been traditionally considered 'men's work.'

At the movies, a couple bought 2 medium drinks and a large popcorn for
$8.50. At the same theater, a family bought 3 medium drinks and 2 large
popcorns for a total of $15.00. What is the cost of a medium drink?

Answers

let's make p stand for popcorn and d for drinks. Using those variables, we can create our equations:
2p + 3d = 18.25
4p + 2d = 27.50

From this, we can use substitution or elimination to solve:
For substitution, in the second equations, we could factor out a 2, divide both sides by 2, and then move the left over 2p to the other side to isolate d to put into the first equation.
For elimination, we can multiply the first equation by -2 so that we can remove the 4p and focus on solving for d.

I'll be using elimination in this case:
-2(2p + 3d = 18.25) --> -4p - 6d = -36.50

-4p - 6d = -36.50
4p + 2d = 27.50
-4d = -9.00
d = 2.25

4p + 2 * 2.25 = 27.50
4p + 4.50 = 27.50
4p = 23.00
p = 5.75

Now let's check our answer:
2 * 5.75 + 3 * 2.25 = 18.25
11.50 + 6.75 = 18.25
18.25 = 18.25

So drinks cost $2.25 and popcorn $5.75

Two airplanes are each traveling at a constant speed.
The table below shows the total number of miles the first airplane traveled as a function of time.
Hours
2 3 4
Total Distance (miles) 320 480 640
The equation y= ax represents the total number of miles, y, traveled by the second plane as a function of the numbers of hours, x,
If the second plane is traveling faster, then what must be true about a ?

Answers

Using proportional relationships, it is found that for the second plane, a > 160.

A proportional relationship is modeled by an equation in the following format:

[tex]y = kx[/tex]

In which k is the constant of proportionality.

For the first plane, we have that when [tex]x = 2, y = 320[/tex], and this is used to find k, hence:

[tex]y = kx[/tex]

[tex]2k = 320[/tex]

[tex]k = \frac{320}{2}[/tex]

[tex]k = 160[/tex]

The second plane is faster than the first, hence, the constant of proportionality is greater, so a > k -> a > 160.
