"Consider two cars manufactured by Chevrolet in 2007. During 2007, Chevrolet sells one of the two cars to Sean for $24,000. Later in the same year, Sean sells the car to Kati for $19,000. The second automobile, with a market value of $30,000, is unsold at the end of 2007 and it remains in Chevrolet’s inventory. The transactions just described contribute how much to GDP for 2007?"

$54,000

Explanation:

If we Consider two cars manufactured by Chevrolet in 2007.

That would be output to be considered in Gross Domestic Product calculation, irrespective of whether they are sold or not.

Since the first  one of the two cars had a value for $24,000.

and The second automobile, with a market value of $30,000,

The transactions just described contribute $54,000 (which is a summation of the total output of both cars) to GDP for 2007.

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.

i would say iii (3) because in order to compare a price you have to use as a reference other near stores because it's its

hope i explained myself
