The second option: (-3)+(-3)+(-3)+(-3)+(-3) is correct because you are multiplying the -3 five times
Hope this helps!
The distance is increasing at a rate that is the speed of the plane multiplied by the cosine of the angle between its flight path and the direct line to the radar station. That cosine is 4/√(3²+4²) = 4/5, so the distance is increasing at
440 mi/h × 4/5 = 352 mi/h
8 oz in 1 poount
therefor, multiply number of poounds by 8 to get ounces
5.5 times 8=44
this is in 1 day
how much in 2 weeks
1 week=7 days
2 weeks=7 times 2=14
1 day=44oz
14 day=44oz times 14=616oz
the answer is 616oz
