Answer:
Prob.3
Denote r: radius of circle O
Formula for calculating AOB sector:
Area = pi*r^2*angle/360
Area = pi*r^2*45/360 = 18 pi
=> r^2 = 18*360/45 = 144
=> r = 12
For prob.4, give it a try, follow the formula I gave. Good luck !
(answer : r = 6)
Answer:
5000 + (0.16)x > 55,000
Step-by-step explanation:
<u><em>DATA:</em></u>
Michael's salary = $55,000
Cole's basic salary = $5,000
--> Commission = 16% of sales
--> Sales = x
<u><em>Cole's total salary</em></u>
<em>--> Basic salary + Commission x sales</em>
--> 5000 + 16% of x
--> 5000 + (0.16)x as 16 percent is equal to 16/100 = 0.16
<u><em>Cole's total salary should be more than Michael's total salary</em></u>
5000 + (0.16)x > 55000
<em>--> Make x the subject</em>
0.16x > 55000-5000
0.16x > 50,000
x > 50,000/0.16
x > 312500
The inequality that represents the dollar amount of sales is 5000 + (0.16)x > 55000.
The dollar amount of sales that Cole must generate should be more than $312500.
