If you worked 19 hours per week at the cashier job, plus three hours a week doing swimming lessons, you'd be working 22 hours exactly, and making $214 per week. I hope this helps, and good luck! :)
To determine the sum of the arithmetic series, simply remember that i is the pattern that you are going by which is 1,2,3.
The top value on the sigma sign tells you the final value that you must go to.
So use the equation to go from 1 to 18. So it would be 2(1) + 9 + 2(2) + 9 etc.
Answer:
9) QR = 4.0
10) AC = 4.1
Step-by-step explanation:
Tan = Opps. / Adj.
9)
Tan(60) = 7 / QR
QR = 7 / Tan(60)
QR = 7 / 1.732
QR = 4.0415
QR = 4.0
10)
Tan (27) = AC / 8
AC = Tan(27) * 8
AC = 0.5095 * 8
AC = 4.076
AC = 4.1
