Answer: to order 200 syringes. At a medical supply store, they charge $0.79 for each syringe. The same syringes from an online distributer cost $0.72 each plus $10.95 for shipping and handling. What would be the lowest cost to get 200 syringes? ... Their hourly rate is $19.52 per hour.
Step-by-step explanation:
Well, what I would do [not sure if it's the correct way], is use the white area as a sector of a circle. The top right of the box is the center of the circle, so the radius is 6.
Then, by the white portion being one quarter of the circle (90° out of 360°), I could calculate the that pink shaded region = the total square (6×6) minus the white sector.
So area (A) of white sector (s): A(s) = 1/4×pi×r^2

36 - 28.27 = 7.73
N+23=19
-23 -23 Takeaway 23 from both sides
Answer is N= - 4
