A pet supply store sells a 20-pound bag of dog food $23.44.Find the unit price.
satela [25.4K]

Answer:

1.172 dollars per pound

Step-by-step explanation:

Given : A pet supply store sells a 20-pound bag of dog food $23.44.

To Find :Find the unit price.

Solution :

Cost of 20-pound bag of food = $23.44

So, Cost of 1-pound bag of food = \frac{23.44}{20}

                                                     = 1.172

For unit price we should divide the cost by no. of pounds

So, the error is you have divided the no. of pounds by cost

Hence the unit price is 1.172 dollars per pound

1. Determine the magnitude of the resultant force acting on the plate and its direction, measured counter-clockwise from the pos
AlexFokin [52]
F1 . . . 100% of it = 900N is in the +x direction.

F2 . . . 70.7% of it (cos45°, 530.3N) is in the +x direction,
and 70.7% of it (sin45°, 530.3N) is in the +y direction.

F3 . . . 80% of it (520N) is in the -x direction,
and 60% of it (390N) is in the +y direction.

Total x-component:  900 + 530.3 - 520  =  1,950.3 N

Total y-component:  530.3 + 390  =  920.3 N

Magnitude of the resultant = √ (x²  +  y²)

                                       = √(1950.3²  +  920.3²)

                                       =  √4,650,070.09

                                       =   2,156.4 N  .

Angle of the resultant, measured counterclockwise
from the +x axis, is 
 
                               tan⁻¹  (y / x)

                         =    tan⁻¹  (920.3 / 1950.3)

                         =    tan⁻¹  (0.4719)

                         =    about    25.3°  .

The same fatigue that degrades my ability to READ the question accurately
may also compromise the accuracy of my solutions.  Before you use this
