It's important because changing the order of operations changes the answer
29) 1/2
30) 3/5
31) 3/4
32) 8/10 equal 4/5
33 not sure
Need to take 25 mg times 18% then times it by 4 then times it again by .01
Answer:
The length is 90.033 and the angle that v makes with the positive x-axis is 153.339°
Step-by-step explanation:
Firstly we will have to convert our given vectors to their rectangular Cartesian vector form as follow,

Now that we have these, we can add them to obtain v as follows,

Now that we have the Cartesian vector form we can calculate its length and its direction with respect to the positive x-axis as follows(In fact we usually refer the angles from the positive x-axis),
So the length of the vector is 90.033 and the angle it makes with the positive x-axis is 153.339°.
