Answer:

The

numerator is 360

Step-by-step explanation:

What we need to do here is make n the subject of the formula;

a = 180(n-2)/n

an = 180n-360

180n - an = 360

n(180-a) = 360

n = 360/(180-a)

Write an equation of the line that passes through the point (-6, -9) with slope-5.
Art [367]

Answer:

y+9=-5(x+6)

Step-by-step explanation:

We are being asked to write the equation in point-slope form:

y-y_1=m(x-x_1) where m = slope and the first point = (x_1,y_1)

In this case, the slope is -5 and the point is (-6,-9) so the equation will be:

y+9=-5(x+6)

matrenka [14]

Jenny won the race as she finished the race much more quickly and has greater average speed than Lester.

\sf \boxed{\sf speed:\frac{distance}{time \ taken} }

Jenny: distance/time = 100/15.2 = 6.58 m/s = 6.6 m/s

Lester: distance/time = 100/15.7 = 6.37 m/s = 6.4 m/s
