Hich of the following statements is correct? Group of answer choices Advertising expense is a product cost Service firms do not incur depreciation costs Human capital is an important resource for service firms, but not for other firms Cardboard packaging for the product is a product cost Sales commissions for the current month is a product cost

Cardboard packaging for the product is a product cost

Explanation:

As we know that

There are two types of cost i.e product cost and the period cost.

The product cost is the cost which is directly related to the product i.e direct material cost, direct labor cost, etc

And, the period cost is the cost which includes the major part of the selling and admin expenses like - sales commission, advertising expense, etc

Plus, the human capital is necessary for all the firms and the depreciation is also charged in all type of business

So the cardboard packaging is the product cost

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.
