Weight of potatoes........Cost
12 lb ................................. $17
18 lb ................................. X
by cross multiplication we get
12 X = 17 × 18
12 X = 306
X = 306/12
X = $ 25.5
The key to your answer is in d): What is a success? What is a failure?
If a patient was -6.0 diopters and after Lasik was -1.00 diopter, most surgeons and those in the industry would consider this a failure. The patient, however, may consider it a success because at age 50 she does not need to use reading glasses and still qualifies for a driver's license with 20/40 distance vision.. A patient who can make out the Snellen 20/20 line - familiar letters in black on a white background in a controlled lighting environment - may be considered by the doctor a success, but the patient does not have the crispness of vision experienced before Lasik and with glasses.
The nonprofit patient advocacy USAEyes.org took a different approach. Success of Lasik means that the patient received what was expected - no matter the numbers. Using a scale of Much Worse Than Expected, Worse Than Expected, As Expected, Better Than Expected, and Much Better Than Expected, the USAEyes Competence Opinion Reletave to Expectations (CORE) patient survey found:
99% report quality of life as expected, better, or much better 98% day vision as expected, better, or much better 98% no complications or issues are seldom problematic 98% would recommend surgery to family and friends. 97% would have surgery again, knowing what they know now 96% wear corrective lenses as often as expected, less, or much less than expected 96% report postop vision without lenses as expected, better, or much better than expected when compared to preop vision with lenses 96% report overall quality of vision as expected, better, or much better than expected 91% no complications at any time 91% night vision as expected, better, or much better 7% complications seldom problematic – yet 91% of these same patients would have surgery again 2% complications frequent or always problematic – yet 22% of f these same patients would have surgery again
Answer:
12.86 sq ft
Step-by-step explanation:
Find area of square and subtract out area of semi-circle; the diameter of the semi-circle equals the side of the square, which is 4 so radius is 2
A(square) = 4 x 4 = 16
A(semi-circle) = πr²/2
= 4π/2 or 2π
Area of Shaded Region = 16-3.14 which is 12.86
