Yusef earned a total of 180 dollars from drawing 12 identically-priced pictures at a festival. write an equation to describe the relationship between p, the number of pictures, and e, the total earnings.

Equation e = 15p is describing the relationship between e and p.

Step-by-step explanation:

In the given question total earning of Yusef is 180 dollars by selling 12 identically priced drawings.Since are drawings are identically priced so we can calculate the price of one drawing.

Price of one drawing = total earning ÷ total number of drawings

                                   = 180÷12 =15 dollars

Now as per question if the number of drawings be p and e is the total earning then applying the same formula

e = price of one drawing × number of drawings

e = 15×p

So the equation e= 15p is describing the relationship.                                  

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

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
