Answer:

45.2  is the constant of proportionality

Step-by-step explanation:

Direct proportionality says that:

y \propto x then the equation is in the form of:

y=kx, where k is the  constant of proportionality

As per the statement:

The distance, d, measured in miles, that Hye drove is

d = 45.2t,         .....[1]

where,

t is the time in hours.

By definition of direct proportionality:

d \propto t

⇒d= kt

On comparing with [1] we have;

k = 45.2

Therefore, the constant of proportionality is, 45,2

The polygon is a regular nonagon (9-sides). What is the sum of the interior angles? What is the measurement for each angle?
lana66690 [7]
Divide the nonagon radially into 9 congruent, equilateral isosceles triangle. Each triangle has vertex angle of 360°/9 = 40°.
Interior angle of polygon = 180°-40° = 140°.
Sum of interior angles = 9(140°) = 1260°
