Q + d = 63....q = 63 - d
0.25q + 0.10d = 10.80
0.25(63 - d) + 0.10d = 10.80
15.75 - 0.25d + 0.10d = 10.80
-0.25d + 0.10d = 10.80 - 15.75
-0.15d = -4.95
d = -4.95/-0.15
d = 33 <=== 33 dimes
q + d = 63
q + 33 = 63
q = 63 - 33
q = 30 <=== 30 quarters
5,000=3.5x-1.9x
5000=1.6x
x=3125
3,125 items must be sold to break even

Answer:
60°
Step-by-step explanation:
tan 60 = sin 60 / cos 60
= [(root 3) / 2] ÷ [1/2]
= root 3
[sin 60 = (root 3) / 2 ; cos 60 = 1 / 2 ]
Answer:
27
Step-by-step explanation:
Factory A proportion:
3 : 2,000
Factory B proportion:
5 : 4,500 (this can be simplified):
1 : 900
Now plug in 18,000 to each proportion:
Factory A:
x : 18,000
3 : 2,000
x = 27
Factory B:
x : 18,000
1 : 900
x = 20
Factory A had the greater amount of defects, 27
