Asubsidy to wheat farmers decreases the price of a bushel of wheat from $2.50 to $2 per bushel. prior to the subsidy, the equilibrium quantity of wheat sold was equal to 200,000 bushels. of the demand for wheat is known to be unit elastic, then after the imposition of the subsidy, bushels of wheat would be sold in the market.

After the imposition of the subsidy, 240,000 bushels of wheat would be sold in the market.

Explanation:

When we talk about unit elastic we mean that the exact same porcentage in quantity demanded is exactly the same porcentage in price reduction.

So if the price of a bushel of weath is reduced 20% ((2.5-2)/2.5) the demand of bushels of wheat will rise in the exact 20% so 200,000*1.2=240,000

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.
