Answer:
C = 
Step-by-step explanation:
given A varies directly as B and inversely as C then the equation relating them is
A =
← k is the constant of variation
to find k use the condition A = 6 , B = 10 , C = 15 , then
6 =
( multiply both sides by 15 )
90 = 10k ( divide both sides by 10 )
9 = k
A =
← equation of variation
when A = 92 and B = 107 , then
92 =
( multiply both sides by C )
92C = 963 ( divide both sides by 92 )
C = 
23° 20' 48" in degrees
Minutes are 1/60 of a degree and seconds 1/60 of a minute.
Let's convert the 48" to minutes.
48/60 = 0.8
23° 20' 48" ⇒ 23° 20.8'
Let's convert the 20.8' to degrees.
20.8/60 ≈ 0.3466667
23° 20.8' ⇒ 23.35°
See how many times 30 fits into 383.
30 x 12 = 360, 30 x 13 = 390
therefore, 30 fits into 383 twelve times.
383 - 360 = 23
you'll have a remainder of 23
B. Abigail used less than Carly and the total was 109.
