Answer:
im not sure but
Step-by-step explanation:
Given : supply voltage = 120V;60 Hz
Inductive Reactance 
Ω
The inductive reactance is given by the formula, 
, where L is inductance and 
is given by formula, 
Apply this, we can say that, 
Answer:
30 ÷ 4 = <em>7.5</em>
Step-by-step explanation:
This means that:
7.5 fits into 30 4 times
Example:
7.5 + 7.5 + 7.5 + 7.5
\______\______/_______/
30
I hope this helps!

PLEASE MARK BRAINLIEST!</u></h2>
The circumference of every circle is (pi) times (diameter).
The diameter is (2 x radius), so we can write
Circumference = (pi) x (2 x radius) .
The question gives us the circumference, and the number to use for (pi).
I shall now pluggum in:
(31.4 cm) = (3.14) x (2 x radius)
Divide each side by 3.14: (31.4 cm)/(3.14) = 2 x radius
Divide each side by 2 : (31.4 cm) / (2 x 3.14) = radius
5 cm = radius
