10/7
Because root of 100 is 10, root of 49 is 7
Answer:
b
Step-by-step explanation:
x=1
5x+8/2=5x+4
9-4= 5
So now you have 5x=5 divide both sides by 5. And you’ll have x=1
1.5(1) - 1 = 1.5 - 1 = .5
The resistance of a material is given by the formula R = ρ*
. Where l is the length and S is the area of the surface calculated with the radius, and ρ is the coefficient that indicates the resistance of a material.
If you keep the lenght and radius, and change the material, ρ will still change and the final resistance (R) will change.
