Answer:
The American population was 20% of the British population.
Step-by-step explanation:
Let us call  the american population,
 the american population,  the British population before the migration, and
 the British population before the migration, and  the population that migrated from America to Britannia.
 the population that migrated from America to Britannia. 
Now, the population  that migrated was 20% of the american population:
 that migrated was 20% of the american population: 
 ,
,
and the same population  increase the British population by 4%:
 increase the British population by 4%: 

Combining equation (1) and (2) we get: 



Thus, the American population was 20% of the British population.
 
        
             
        
        
        
Corresponding angles are angles that are the same, and occupy the same relative position.
1 and 2: Incorrect - These are supplementary angles
3 and 5: Incorrect - These are same-side interior angles
2 and 6: Correct - These are corresponding angles
4 and 7: Incorrect - These are alternate interior angles

Answer:
Option D 3/16 
Step-by-step explanation:
Carol is cross-country skiing.
With the help of the given table we have to calculate the rate of change.
If we draw a graph for distance traveled on y-axis and tins at x-axis we find two points, ( 2, 1/6) and (3, 17/48).
Then slope of the line connecting these points will be the rate of change.
Rate of change = Slope = 
= 
= 
= 
Option D 3/16 is the answer.
 
        
                    
             
        
        
        
Answer:
f(3)=21
Step-by-step explanation:
f(1)=3 
f(n)=2f(n-1)+3
n=2
f(2)=2f(2-1)+3
f(2)=2f(1)+3
f(2)=2*3+3
f(2)=6+3
f(2)=9
n=3
f(3)=2f(3-1)+3
f(3)=2f(2)+3
f(3)=2*9+3
f(3)=18+3
f(3)=21
