1. The fourth graph: D
2. The first graph: A
In a regular polygon, each exterior angle equals each central angle.
central angle = 360 / #sides
#sides = 360 / central angle
#sides = 360 / 60
#sides = 6
The sequence can be represented by
, where
is a whole number(
and
is an integer). By this, we should be able to plug in some whole number x and be able to get these values if they are in the sequence. To test this, let's set these numbers equal to
and confirm that there is a whole number x which equals the values selected.



When trying 160 with our equation, we find that x doesn't equal a whole number, thus our answer is C, or 160. To confirm our answer, we can test 170 and 210 and confirm that they both give us a value for x which is a whole number.


What is the question can't help with ought it
Answer:
Population in 1950 was 4,100,000
Step-by-step explanation:
Equation: 5x + 2,000,000 = 22,500,000
Subtract 2,000,000 from each side: 5x = 20,500,000
Divide each side by 5: x = 4,100,000
