Answer:
s = 6 cm
Step-by-step explanation:
the area (A) of a square is calculated as
A = s² ( s is the side length )
given A = 36 , then
s² = 36 ( take square root of both sides )
s =
= 6
dividido por la epotenusa es 7 :v
question a is 80
question b 20 (is what I could find but not completely sure)
Answer:
600 volts
Step-by-step explanation:
Given =
A = 12 ampere
V = 480 volts
A2 = 15 ampere
Solution =
R = V/I
= 480 / 12
= 40 ohms
R = V / I
V = R x I
= 40 x 15
= 600 volts
