Explain why the supermarket industry is an oligopoly

Answer and explanation:

An oligopoly is when the market is controlled by a small group of two or more companies. Oligopoly firms may consent to market collusion, and build obstacles to new trade entry. If the businesses do not, they will be forced to lower their prices and open the markets to new and smaller firms.

Supermarkets are oligopolies because in every market there are a few companies offering the same products just like them with small differentiation between one and another, providing those goods to relatively similar prices.

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.
