Acompany has the choice of either selling 600 defective units as scrap or rebuilding them. the company could sell the defective units as they are for $2.00 per unit. alternatively, it could rebuild them with incremental costs of $0.60 per unit for materials, $1.00 per unit for labor, and $0.80 per unit for overhead, and then sell the rebuilt units for $5.00 each. what is the amount of incremental revenue from rebuilding?

Incremental revenue =360

Given:

N=600 (number of defective units)

P1=$2 (price if not rebuilt)

P2=$5 (price after rebuilt

X=.60+1.0+.80=2.4 (incremental costs)

R1=600(2)=1200

R2=600(5)-600(2.4)

R2=3000-1440

R2=1560

Incremental revenue is computed as:

R2-R1

1560-1200

360

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.
