1.The second industrial revolution refers to the changes in manufacturing and building, and the new inventions brought about by the introduction of inexpensive steel. After the Second Industrial Revolution cites were overcrowded because of the need of jobs for people. The streets of cities were overcrowded which had sanitation issues so, lots of people were getting sick as a result. Crime grew as a result of not enough police and because it was easy to lose the police in crowds of people. Devices such as cars, electric lights, and telephones made the middle class's life more enjoyable. People who did urban planning reforms such as trolly parks made it so the working class could spend their extra time and money on something enjoyable.
2.One of the largest effects that we still deal with all over the war is Slavery. The Atlantic Slave Trade is a well-known trade route used to trade slaves and items through Africa.Through the trade and conquering of Africa by the Europeans, weapons and processed items were traded with the Africans.The trade of items allowed major groups to prosper and continue to grow. This eventually resulted in large African kings defending their lands against the powerful Europeans when they attacked.

You could change 0.393 to a fraction by putting it over 1000
in this case put it over 0.393= 396/1000
the / is the fraction 
it is 396 over 1000
        
                    
             
        
        
        
Suppose the dimensions of the rectangle is x by y and let the side enclosed by a house be one of the sides measuring x, then the sides that is to be enclosed are two sides measuring y and one side measuring x.
Thus, the length of fencing needed is given by
P = x + 2y
The area of the rectangle is given by xy,
i.e. 

Substituting for y into the equation for the length of fencing needed, we have

For the amount of fencing to be minimum, then

Now, recall that 

Thus, the length of fencing needed is given by
P = x + 2y = 24 + 2(12) = 24 + 24 = 48.
Therefore, 48 feets of fencing is needed to enclose the garden.
 
        
        
        
Answer:
7,500 Pages 
Step-by-step explanation:
So this printer can prink 25 pages in 1 (x) minute.
There are 60 minutes in an hour and we are waiting 5 hours, so 5x60 = 300 minutes.
Then you take the 300 and plug it in for x because that is how many minutes we are waiting for.  Now your equation should look like this:
p(x) = 25(300)
Next you multiply 25 x 300 and you get 7,500 pieces of paper
