Rhed kennel uses tenant-days as its measure of activity; an animal housed in the kennel for one day is counted as one tenant-day. during december, the kennel budgeted for 3,700 tenant-days, but its actual level of activity was 3,650 tenant-days. the kennel has provided the following data concerning the formulas used in its budgeting and its actual results for december: data used in budgeting: fixed element per month variable element per tenant-day revenue - $ 33.90 wages and salaries $ 2,200 $ 7.70 food and supplies 1,400 12.90 facility expenses 8,200 4.40 administrative expenses 6,200 0.40 total expenses $ 18,000 $ 25.40 actual results for december: revenue $ 122,235 wages and salaries $ 30,575 food and supplies $ 47,455 facility expenses $ 24,360 administrative expenses $ 7,460 the spending variance for facility expenses in december would be closest to:

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.

the answer would be voluntary exchange -

"the act of buyers and sellers freely and willingly engaging in market transactions. moreover, transactions are made in such a way that both the buyer and the seller are better off after the exchange than before it occurred."
