Answer:
1/2n - 4 = 17
add four to both sides
1/2n = 21
n = 42
Step-by-step explanation:
Answer:
the width is 9
the length is 11
Step-by-step explanation:
x(2+x)=99
x=the width
First you need to know the formula of the Resistance(R) of a conductor, which is:
![R = \frac{K*L}{CM}](https://tex.z-dn.net/?f=R%20%3D%20%20%5Cfrac%7BK%2AL%7D%7BCM%7D%20)
-- (A)
Where,
R = Resistance of the wire = ?
K = Specific resistance of the wire(In this case Aluminum at 68°F) = 17.02 ohm-circular-mil-foot
L = Length of the wire(in feet)
CM = Circular mil Area(In inches)
Now in order to use the above formula(A), we have to first convert TWO quantities:
1) The length of the wire(from miles to feet)
2) Mils to Circular mil Area
1.
The length of the wire given = 2 miles
The length of the wire(In feet) = 10560 ft
2.
Since the mils given = 100 mils.
Therefore,
Circular mils(Circular mil Area) = mils x mils = 100 x 100 = 10000
Now plug-in the values in equation(A):
A=> R =
![\frac{17.02 * 10560}{10000 }](https://tex.z-dn.net/?f=%5Cfrac%7B17.02%20%2A%2010560%7D%7B10000%20%7D%20)
R = 17.97 ohms
Ans: Resistance of the aluminum wire = 17.97 ohms.-i
