Answer: There would be 745 books at the end of month 10.
Step-by-step explanation:
Since we have given that
Number of books initially = 80
Rate of growth = 25% = 0.25
t = 10 months
We need to find the number of books that are expected at the end of month 10.
As we know the formula for "Compound interest":

Hence, there would be 745 books at the end of month 10.
Graphs can be used to model real-world situations
- Segment 8 means: people are leaving the arena
- Segments 5 and 7 represent, intervals where there was no incoming or outgoing fans.
- Segment 6 means a few people left, when the game was going to an end.
Segment 8
From the graph (see attachment), we have the following observations
- Segment 8 is at the second half of the graph
- Segment 8 connects segment 7 and 9 (i.e. from the top, downwards)
The above points imply that:
Fans are leaving the arena at segment 8
Segments 5 and 7
From the graph, segments 5 and 7 are horizontal lines.
This means that:
No entry or exit was observed by the fans, at segments 7 and 5
Segment 6
Segment 6 connects segments 5 and 7, with a short downward line
This means that:
Few people left the arena, at segment 6
See attachment for the graph

Answer:
<u>Gina's height in inches</u><u>:</u> 63 inches
<u>Noelle's height in inches</u><u>:</u> 67 inches
<u>Equation</u><u>:</u> n + (n - 4) = 130
Step-by-step explanation:
n + (n - 4) = 130
n + n - 4 = 130
2n - 4 = 130
2n - 4 + 4 = 130 + 4
2n = 134
2n ÷ 2 = 134 ÷ 2
n = 67
67 - 4 = 63
