By Faraday's Law, if a conducting wire of length ℓ meters moves at velocity v m/s perpendicular to a magnetic field of strength

B (in teslas), a voltage of size V = −Bℓv is induced in the wire. Assume that B = 8 and ℓ = 0.7. Find the rate of change dV/dv.

The total cost of a jacket and a pair of shoes was $95.11. If the price of the jacket was $2.79 less than the pair of shoes, wha

vovangra [49]

The <em>cost of the jacket</em> purchased using the <em>System of equation</em> is $46.16

<u>Given the cost prices</u> :

Total cost = $95.11
Cost of shoes = x
Cost of jacket = x - 2.79

<u>We could set up an equation relating the cost of each item to the total Cost : </u>

<em>Total cost = cost of jacket + cost of shoes</em>

95.11 = x - 2.79 + x

95.11 = 2x - 2.79

95.11 + 2.79 = 2x

97.90 = 2x

x = 97.90 / 2

x = 48.95

Cost of jacket = $48.95 - 2.79 = $46.16

Therefore, Cost of jacket is $46.16
