Anna007 [38]
For -4+3,
1. start with zero
2. move to left (-x axis) for 4 units (-4)
3. then move to right (+x axis) for 3 units (+3)

For 3+(-4)

Island A is 160 miles from island B. A ship captain travels 220 miles from island A and then finds that he is off course and 200
Angelina_Jolie [31]

Answer:

=135.53°

Step-by-step explanation:

The bearing that the captain should turn is the angle difference between the two islands from the position of the ship.

Let C be the position of the ship, then

AB is c=160

AC is b=220

BC is a=200

We use the cosine rule as follows:

c²=a²+b²-2ab Cos C

160²=200²+220²-2×200×220 Cos C

25600=88400-88000Cos C

88000 Cos C=88400-25600

88000Cos C=62800

Divide both sides by 88000.

Cos C=62800/88000

=0.7136

C=44.47°

He should turn (180°-44.47°)=135.53°

Find the Take-Home percent of the Gross Pay: Net Pay $453.10, Gross Pay$734.
Step2247 [10]
Net pay = $453.10
Gross pay = $734
Take home percent of the gross pay = (453.10/734) * 100
                                                           = 61.73%
From the above deduction, it can be easily concluded that the Take-Home percent of the Gross Pay is 61.73%. I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
