Accompanying a bank statement for Borden Company is a credit memo for $21,200 representing the principal ($20,000) and interest ($1,200) on a note that had been collected by the bank. The company has been notified by the bank at the time of the collection but had made no entries.

The journal entry to record this note collection carried out by the bank should be:

Dr Cash 21,200

    Cr Notes receivable 20,000

    Cr Interest revenue 1,200

Explanation:

Notes receivable is an asset account and it probably represented a sale made on credit by the company, so when it was collected, the amount should decrease and that is done by crediting it.

On the other hand, since only $20,000 belonged to the note, the rest ($1,200) must be recorded as interest revenue. Revenues are always credited.

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.
