During year 4, King Company made the following expenditures relating to its plant building: Continuing and frequent repairs $40,000 Repainted the plant building 10,000 Major improvements to the electrical wiring system 32,000 Partial replacement of roof tiles 14,000 How much should be charged to repair and maintenance expense in year 4

$64000

Explanation:

The amount that should be charged to the repair and maintenance expense in year 4 will be calculated thus:

Continuing and frequent repairs = $40,000

Add: Repainted the plant building = $10,000

Add: Partial replacement of roof tiles = $14,000

Repair and maintenance expense = $64,000

hardwork and determination

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.
