Answer:
9 sides
Step-by-step explanation:
Given the sum of the interior angles = 1260°, then
180° (n - 2) = 1260 ( divide both sides by 180 )
n - 2 = 7 ( add 2 to both sides ), hence
n = 9

Answer: 150.80 inches.
Step-by-step explanation:
OK. So first, slope = rise/run. This can be calculated with any 2 points from the graph above.
I will use points (24, 168) and (8, 56).
Slope = (168 - 56) / (24 - 8)
Slope = 7
Since the y-intercept is 0, the equation is y = 7x
B should be the correct answer.

Answer:
108.7 ft
Step-by-step explanation:
Put 30 where x is and do the arithmetic.
y = -3.29·30 -10 = -98.7 -10 = -108.7
The trend line predicts the depth to be 108.7 ft after 30 minutes.

<em>Comment on this problem</em>
Real-world considerations in scuba diving may cause the diver to level off or head toward the surface before 30 minutes elapse. The trend line does not model these effects.
