A
Step-by-step explanation:
3/24=9/72 3*3=9 24*3=72 x=3
3/9=y/12 9/3=3 12/3=4 y=4
X=3 y=4
Answer:
<em>AB = 7.35 cm</em>
Step-by-step explanation:
From the attachment,
In ΔDEF,
DF = GH-(GD+FH) = 6 - (2+3) = 1 cm
DE = 2+3 = 5 cm (sum of two radius)
Applying Pythagoras theorem,

In ΔCDI,
DI = GH-(GD+IH) = 6 - (2+1.5) = 2.5 cm
CD = 2+1.5 = 3.5 cm (sum of two radius)
Applying Pythagoras theorem,

AB = EF + CI = 
Answer: C
The graph is continuous because there can be fractional values for time
