Answer:
B = 1.875
Step-by-step explanation:
given that 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 = 12 when B = 3 and C = 2 , then
12 =
( multiply both sides by 2 to clear the fraction )
24 = 3k ( divide both sides by 3 )
8 = k
A =
← equation of variation
when A = 10 and C = 1.5 , then
10 =
( multiply both sides by 1.5 )
15 = 8B ( divide both sides by 8 )
1.875 = B
Answer:
1 * 5 = 5cm
3 * 5 = 15cm
2 * 5 = 10cm
Step-by-step explanation:
1+3+2 = 6
then do 30 / 6 = 5 to find one part of the ratio
1 * 5 = 5
3 * 5 = 15
2 * 5 = 10
