Which of the following illustrates the internal control procedure—separation of duties? a. the invoices and other documents must be pre-numbered. b. the company separates the custody of assets from accounting. c. electronic devices must be installed to reduce theft. d. external auditors will monitor internal controls.

Option B  

Explanation: Separation of duties refers to the process under which the organisation sets the duties of two people to complete a particular task. This is seen as an internal control which is done with the objective of prevention of fraud.

Thus, in the option B the company is separating the custody of assets from accounting and giving it to some other department also this will result to double monitoring of transactions.

Hence from the above we can conclude that the correct option is B.

answer; ///the correct answer is (ftc) federal trade commission;

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.
