Overhead Variances, Four-Variance Analysis Oerstman, Inc., uses a standard costing system and develops its overhead rates from the current annual budget. The budget is based on an expected annual output of 125,000 units requiring 500,000 direct labor hours. (Practical capacity is 520,000 hours.) Annual budgeted overhead costs total $840,000, of which $595,000 is fixed overhead. A total of 119,500 units using 498,000 direct labor hours were produced during the year. Actual variable overhead costs for the year were $260,400, and actual fixed overhead costs were $555,450. Required: 1. Compute the fixed overhead spending and volume variances. Fixed Overhead Spending Variance $ 39,550 Favorable Fixed Overhead Volume Variance $ 2. Compute the variable overhead spending and efficiency variances. Do not round intermediate calculations Variable Overhead Spending Variance $ Variable Overhead Efficiency Variance $

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.
