Mel spent $47.97 on three cds. Two of the cds were the same price, and the third cd cost $5.00 more than one of the other two cds. The total cost can be represented by the equation 2c + (c+5) = 43.97, where c is the cost of one lower-priced cd. What was the cost of the higher priced cd?

Given :

The total cost can be represented by the equation 2c + (c+5) = 43.97, where c is the cost of one lower-priced cd.

To Find :

The cost of the higher priced cd.

Solution :

Solving given equation :

2c + c + 5 = 43.97

3c + 5 = 43.97

3c = 43.97 - 5

3c = 38.97

c = $12.99

Therefore, cost of higher priced cd is $( 12.99 + 5 ) = $17.99 .

Hence, this is the required solution.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
