1 divided by 138 is roughly .7%. Run it through a calculator, then convert the decimal
Answer:
4 1/2
Step-by-step explanation:
The point is marked at -4 1/2 on the number line. The distance from there to the origin is 4 1/2 units.
(Distances and lengths are always positive—as are values derived from them, such as perimeter or area.)
Answer:
I am guessing the answer would be...
A. (2.2)
Step-by-step explanation:
A proportional relationship is a relationship where the ordered pairs are the same. 2 and 2 are the same.
Let angle ladder makes with the ground be x degrees.
sin x = 11.8/12
x = sin^-1(11.8/12)
x = 79.5 degrees (3 s.f.)
yes it is possible
d = diameter of the copper wire = 8.252 mm
r = radius of the copper wire = d/2 = 8.252 mm /2 = 4.126 mm = 0.004126 m
A = area of cross-section of the copper wire = πr² = (3.14) (0.004126)² = 53.5 x 10⁻⁶
L = length of the copper wire = 2.40 km = 2400 m
ρ = resistivity of copper wire = 1.68 x 10⁻⁸
resistance of copper wire is given as
R = ρL/A
inserting the above values in the formula
R = ( 1.68 x 10⁻⁸)(2400)/(53.5 x 10⁻⁶)
R = 0.753 ohm
