Answer:
Never
Step-by-step explanation:
Using the formula to find the sum of the interior angles, (n-2) * 180, we can work backwards.
300/180 +2 = 11/3 or 3.666. Polygons cannot have decimal sides therefore your answer is never.
Answer:
-.91
Step-by-step explanation:
I'm not 100% sure, because i don't have graphing calculator on me, but the correlation coefficient is how well the line of best fit goes with the data, and the data points on the graph look like they match the line. The closer the correlation coefficient is to 1 or -1, means that it has a strong correlation coefficient. It's negative because the slope of the line is negative. If you really want to make sure, you can plug it into a graphing calculator in STAT.
The small plane has the following parameters
Distance = 1200 miles
Speed = 300miles/hour
time = ?

If a Boeing 747 leaves 2 hours later, the total time becomes 4hours + 2 hours = 6 hours
Considering the distance of the small plane after 6 hours, we have

So the total distance = 1800 miles
Hence the speed of the Boeing 747 will be


The average speed of the Boeing 747 is 900 miles/ hour
Answer:
263.76
Step-by-step explanation:
The formula is pi(3.14) times r(radius squared) (6^2) times h(height)( 7) over 3
3.14 times 36 times 7/3
I believe it is the second one
