Answer:
R 42.26
Step-by-step explanation:
To calculate the bill correctly we must add the orders separately and in the sweet cost when adding, we should write it as 0.59 not 59.
my order my friend's order
20.50 10.29
+ 10.29 + 0.59
<u> </u> 0.59
R 30.79 <u> </u>
R 11.47
<em>R 30.79 + R 11.47 = </em><em>R 42.26</em>

Answer:
4
Step-by-step explanation:
Yeah if you don't know this one... you're... special.
Force 1, F1 = 90, angle 30°
Force 2, F2 = 50, angle 160°
F1 = 90 cos(30) i + 90 sin (30) j
F2 = 50 cos (160) i + 50 sin (160) j
F1 = 90*0.866 i + 90*0.5 j
F2 = 50*(- 0.940) i + 50*0.342 j
F1 = 77.94 i + 45 j
F2 = -47 i +17.10 j
Resultant force, Fr = F1 + F2
Fr = [77.94 - 47.00] i +[45 +17.10]j = 30.94 i + 62.10 j
Magnitude = √[30.94 ^2 + 62.10^2] = 69.38 pounds
Direction = arctan[62.10/30.94] = 63.52 °
