Please Help! I'm stuck on this question. Show all work!
Valentin [98]

Add all the displacement vectors together, then find the magnitude of this vector sum.

\vec r_1=(72\,\mathrm{km})(\cos60^\circ\,\vec\imath+\sin60^\circ\,\vec\jmath)

\vec r_2=(48\,\mathrm{km})(\cos270^\circ\,\vec\imath+\sin270^\circ\,\vec\jmath)

\vec r_3=(100\,\mathrm{km})(\cos150^\circ\,\vec\imath+\sin150^\circ\,vec\jmath)

Summing these vectors gives the resultant displacement

\vec r=\vec r_1+\vec r_2+\vec r_3\approx(-50.6\,\vec\imath+64.4\,\vec\jmath)\,\mathrm{km}

and we have

\|\vec r\|=\sqrt{(-50.6)^2+64.4^2}\,\mathrm{km}\approx\boxed{81.9\,\mathrm{km}}

so the plane ends up about 81.9 km away from its starting position.

Brian is going clothes shopping. He buys one t-shirt for $10 and “x” amount of shorts for $5 each, in total he spent $30. Solve
slava [35]
Brian bought 4 pairs of shorts. so x equals four.
to get the answer you subtract 10 from 30 which gives you 20, then you divide 20 by 5, which gives you four.

Hope this helps :)

Carolina moved the hand of a spinner 270° as shown below what fraction of a complete turn through a circle is 270°
Keith_Richards [23]
For this case, the first thing you should know is the number of degrees that a complete circumference has.
 The number of degrees of the full circle is 360 degrees
 Therefore, the fraction that represents 270 degrees is:
 270/360
 Answer:
 
270/360
