"Zero Turbulence Airline provides air transportation services between Los Angeles, California, and Kona, Hawaii. A single Los Angeles to Kona round-trip flight has the following operating statistics: Fuel $15,961 Flight crew salaries 12,226 Airplane depreciation 5,773 Variable cost per passenger—business class 60 Variable cost per passenger—economy class 50 Round-trip ticket price—business class 550 Round-trip ticket price—economy class 310"

Explanation:

To Determine

(a) Break-even Point in Sales (units) = Fixed Costs / Contribution Margin

Fixed Cost =(15,961 + 12,226 + 5773) = $33,960

Contribution Margin  per unit = $228

$33,960/$228

=140 seats

selling price per unit product = (550 per seat X 10%) + (310 per seat X 90%)

= 55 + 279

=334

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.
