Before you started applying for college, a job recruiter offered you a full-time cashier position at a local retail store, earning an after-tax salary of $24,000 per year. However, you turn down this offer and attend your first year of college. The additional monetary cost of college to you, including tuition, supplies, and additional housing expenses, is $38,000. You decide to go to college, probably because

Explanation:

The concept involved here is opportunity cost. Opportunity cost is the loss one incurs by choosing the best alternative for himself.

The student would choose to go to college because he believes that the opportunity cost ( 24000+38000) is less important to him than going to college(best alternative). Completing college would earn him a degree that could fetch him a better paid job than his current job.

what do you mean.why did u repeat the question.

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.
