Which of the following equations describes the contribution margin ratio? A. 1 -(Variable Costs / Sales)
B. (Variable Costs - 1/ Sales
C. (Sales-1) / Variable Costs
D. Sales* (1-Variable Costs) / Variable Costs
E. None of the above

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.

c.

explanation:

regressive tax taxes the poor and less of the wealthy. this the rich get richer and the poor get more poor. this would create a large wealth gap.
