Average cost of electricity per household

The price that a farmer asks for her watermelons.

Explanation:

Microeconomics is a branch of economics that studies the decisions individuals and firms make in response to changes in economic factors. These factors include price, resources etc. it studies how firms and individuals allocate and make decisions about resources

The other options are examples of macroeconomics.

Macroeconomics is a branch of economics that studies the economy as a whole. Macroeconomics studies economic aggregates such as inflation, unemployment, GDP and growth rate.

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.
