Suppose all of the banks in the federal reserve system have $100 billion in transactions accounts, the required reserve ratio is 0.25, and there are no excess reserves in the system. if the required reserve ratio is changed to 0.20, the total lending capacity of the system is increased by

$25 billion

Explanation:

The difference between a 0.25 reserve ration and a 0.20 reserve ratio is 0.05, which represents $5 billion in available money (= 0.05 x $100 billion).

If the total bank reserves is $100 billion, and the reserve ratio is 0.20, the money multiplier = 1 / 0.20 = 5.

If the banks have $5 billion available for loans and the new money multiplier = 5, then the lending capacity of the banking system will increase by $25 billion (= $5 billion available x money multiplier).

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.

if i need to borrow money for anything, it would be for something like a house or an apartment but, that depend on the situation.

is this good enough?
