A depositor places $10,000 in cash in a commercial bank, where the required reserve ratio is 10 percent. The bank sends the $10,000 to its Reserve. As a result, the actual reserves (R), required reserves (RR) , and excess reserves (ER) of the bank have been increased by .
a. $10,000, $9,000, and $1,000, respectively.
b. $10,000, $500, and $4,500, respectively.
c. $10,000, $1,000, and $9,000, respectively.
d. $1,000, $10,000, and $9,000, respectively

C) $10,000, $1,000, and $9,000, respectively.

Explanation:

the money deposited by the client = $10,000

bank's reserve ratio is 10% = $10,000 x 10% = $1,000

since the bank kept the whole $10,000 as reserves, then:

The bank is only required to keep $1,000 in reserves, this means it can borrow the remaining $9,000 whenever they want.

statement of owner's equity;

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.
