Plz solve these 2 Questions. I will mark u as BRAINLIEST for correct answer

Q1: A trader buys q pencils at $y each and sells them at 3 for $z each. Find an expression for the total profit.

Q2: Make "m" as subject for the formulae and hence find the value of m where k =100, x= -3, y= 6k - 3mx = 3my/4

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet

step-by-step explanation:
