42. 0.01 is really 0.0100. If you subtract 0.0001 then it is like subtracting 100-1 = 99 but in the decimal place. So it becomes 0.0099.

Answer:
C. 60%
Step-by-step explanation:
<u>Consider 1st row of table</u>
Total Price = P= 22.50
Discount=D=13.50
Percent discount=(D/P) x 100
=(13.5/22.5) x 100
= 60%
<u>Consider 2nd row of table</u>
Total Price = P= 27
Discount=D=16.20
Percent discount=(D/P) x 100
=(16.2/27) x 100
= 60%
Now we know discount rate is r=60%
Answer:
C
Step-by-step explanation:
The secant- secant angle SPR is half the difference of the intercepted arcs, that is
55° = 
(RS - QT ) ← multiply both sides by 2
110° = RS - QT = RS - 50° ( add 50° to both sides )
160° = RS → C
