How many sides does a regular polygon have if each exterior angle measures 30 degree
Nataly [62]
As the exterior angles always add up to 360, you can find the number of sides by dividing 360 by the measure of your exterior angle, 30. This gives you 360/30=12, meaning your polygon has 12 sides.

Answer:

m=7w+4

Step-by-step explanation:

<u>Linear Modeling</u>

It consist is setting up a linear relationship between two variables, given some experimental data. Only 2 points are needed to set up the equation of a line, but if more than 2 points are used, then the result should use statistical approaches like linear regression to find the best-fit line.

For the question at hand, Marty practices his piano lessons 11 minutes the week #1. It provides the first point (1,11). He practices 25 minutes per day on the third week. It gives us another point (3,25). This is enough to find the equation of a line. The general formula for a line, having two points (m1,w1) (m2,w2) is

\displaystyle m-m_1=\frac{m_2-m_1}{w_2-w_1}(w-w_1)

Let's plug in our values

\displaystyle m-11=\frac{25-11}{3-1}(w-1)

Simplifying:

m-11=7w-7

\boxed{m=7w+4}
