Can't help u there I'm so sorry
If they want you to find the perimeter I guess you add all sides so 9+9+9+9+30 = 66
2/3 and 12/18 are equivalent fractions, and 12+18 = 30 so the answer is 12:18
Answer:
dI/dt= -0,000127 A/s
Step-by-step explanation:
From Ohm's Law we have V = IR . deriving on both sides of equality
dV/dt = dI/dt R + I dR/dt . clearing, dI/dt = 1/R (dV/dt - I dR/dt)
replacing by the values of the statement
dI/dt = 1/400Ω (-0,05 V/s - 0,02 A 0,04Ω/s) . making calculations
dI/dt = -0,0508V/s / 400Ω = -0,000127 V/sΩ. simplifying the units
dI/dt = -0,000127 A/s
Answer:
Area of square=144 square inche
Perimeter of square=48 inche
Step-by-step explanation:
length =12
Area of square=length x length
Area of square=12 x 12
Area of square=144
Area of square=144 square inche
Perimeter of square=4 x length
Perimeter of square=4 x 12
Perimeter of square=48
Perimeter of square=48 inche
