Lo 2.2explain the differences among fixed costs, variable costs, and mixed costs.

Explanation:

There are primarily two types of costs, i.e. variable costs and fixed costs. The variable cost is the cost that varies when the level of production changes, whereas the fixed cost is the cost that remains constant, whether the level of production changes or not.

Therefore, indirect material indirect labor, and factory supplies are included in the variable costs, and the fixed costs include supervision taxes and depreciation expenses.

The mixed cost is a mix combination of both the variable cost and the fixed cost which includes some components of fixed cost and some components of variable cost. It is also known as semi-variable cost

Example - transportation cost, tel communication cost, etc

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.
