Carla vista co. sells office equipment on july 31, 2017, for $21,240 cash. the office equipment originally cost $86,550 and as of january 1, 2017, had accumulated depreciation of $35,470. depreciation for the first 7 months of 2017 is $4,710.prepare the journal entries to (a) update depreciation to july 31, 2017, and (b) record the sale of the equipment.

Explanation:

The journal entries are shown below:

a. Depreciation Expense A/c Dr $4,710

        To Accumulated Depreciation - Office equipment A/c  $4,710

(Being depreciation expense is recorded)

The depreciation expense is calculated for eight months (January - August)

b. Cash A/c Dr $21,240

   Accumulated Depreciation - Office equipment A/c Dr $40,180

   Loss  on Disposal of Office equipment A/c Dr $25,130

                 To Office equipment A/c $86,550                

(Being sale of machinery is recorded and the remaining balance is debited to the Loss on Disposal of Office equipment A/c)

The accumulated depreciation is computed below:

= $35,470 + $4,710

= $40,180

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.
