Observe that as the series progresses, the term decreases by 1/4. To show this, observe the first four terms of the series below.
-200 = (1/4)(-800)
-50 = (1/4)(-200)
-12.5 = (1/4)(-50)
Since we have a common ratio, r, of 1/4, we can use the properties of a geometric series to find the 8th term of the series.
Recall that to find the sum of the nth term of a geometric series, we have

where a is the first term of the series and r is the ratio.
So, for the first eight terms, we have


Therefore, the sum of the 8th series is approximately -1066.65. 
Answer: -1066.65
 
        
        
        
Answer:
All of the above
Step-by-step explanation:
The question is asking you which equation you can use for you to find the value of the undefined variable, n.
In this case, all of the equations above are eligible to find the value of the variable n since regardless of the variable position, you will yet be able to find its value.
 
        
                    
             
        
        
        
Answer:
95.1CM²
Step-by-step explanation:
THERE ARE 3 SHAPES
-AREA OF RECTANGLE=LXB
=21 X 3 = 63 CM²
-AREA OF SQUARE = SXS
=5 X 5= 25CM²
-AREA OF CIRCLE = Pi x r²
RADIUS = HALF OF DIAMETER = 1.5
=3.14 X 1.5 ²
=3.14 X 2.25
=7.065
TOTAL AREA= 63 + 25 + 7.065=
ROUNDED = OPTION B 
=95.1 CM²

Answer:
675 total attendees at the conference.
Step-by-step explanation:
Let x represent total attendees at the conference.
We have been given that at a conference the organizer determined at 32% of the attendees were between the ages of 18 and 29. There were 216 attendees in this age range. We are supposed to find the total attendees at the conference.
To find the number of total attendees at the conference, we will set as equation where 32% of x is equal to 216.




Therefore, there were 675 total attendees at the conference.
