Suppose the interest rate on your car loan is 19.00% and the inflation rate is 18.00%. Calculate the real interest rate

1%

Explanation:

The real interest rate is the interest rate adjusted for inflation. It is the rate after accounting for inflation. The real interest rate is the difference between the inflation rate from the quoted(nominal )interest rate.

real interest rate = quoted interest rate - inflation rate

=19% - 18%

=1%

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.
