Since 4 is between 2 & 5 you input it into the middle equation.
x=4
so the answer is 4!
Answer:

Step-by-step explanation:

Answer:
7cm
14cm
dπ or 2r π
14π or 2(7π)
Step-by-step explanation:
Radius = 7cm
Diameter = 7 x 2 = 14cm
Circumference = 2 x π x r = dπ
Circumference Value = 2 x π x 7 = 14π
Answer:
11.5
Step-by-step explanation:
Simple interest formula:

where
I = interest
P = principal
r = rate
t = time
In your case,
P = $4,000
I = $4,920 - $4,000 = $920
t = 2 years
So,

The rate as decimal is 0.115 that is 11.5% as percent
