Using personal computers in auditing may affect the methods used to review the work of staff assistants because

Audit documentation may not contain readily observable details of calculations.

Explanation:

This is because unlike paper based working documentation which tend to details each of the cost or expenses and profits made, utilizing personal computers in auditing may influence the techniques used to review the work of staff assistants because oftentimes using audit documentation may not comprise readily noticeable elements of calculations.

Hence, in this case, the correct answer is: Audit documentation may not contain readily observable details of calculations.

answer; i believe the answer is (facework);

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.
