Agrocer wants to make a 10-pound mixture of peanuts and cashews that he can sell for $4.75 per pound. if peanuts cost $4.00 per pound and cashews cost $6.50 per pound, how many pounds of each should he use? let p = pounds of peanuts and let c = pounds of cashews. write a system of equations that could be used to solve the problem.

The required system of equations is,

p + c = 10

4.00p + 6.50c = 47.5

Step-by-step explanation:

Here p represents pounds of peanuts and c represents pounds of cashews,

Given,

Total pounds = 10,

⇒ p + c = 10,

Also, the total pounds is sold at the rate of $4.75 per pound,

So, the total expenditure = 4.75 × 10 = $ 47.5

Peanuts cost $4.00 per pound and cashews cost $6.50 per pound,

Total expenditure = ( 4.00p + 6.50c ) dollars,

⇒ 4.00p + 6.50c = 47.5

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

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
