Keller Cosmetics maintains an operating profit margin of 5% and asset turnover ratio of 3. a. What is its ROA? (Round your answer to 2 decimal places.) b. If its debt-equity ratio is 1, its interest payments and taxes are each $8,000, and EBIT is $20,000, what is its ROE? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

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.

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30
