Answer:

y = -11/6z - 6

Step-by-step explanation:

11z +6y = -36

-11z          -11z

6y = -11z -36

-----  -----  -----  divide by 6

6       6       6

y = - \frac{11}{6\\} z -6

A ship leaves the port of Miami with a bearing of S80°E and a speed of 15 knots. After 1 hour, the ship turns 90° toward the sou
CaHeK987 [17]

Answer:

The bearing is N 55.62° W

Step-by-step explanation:

ship leaves the port of Miami with a bearing of S80°E and a speed of 15 knots.

It then turns 90° towards the south after one hour.

Still maintain the same speed and direction for two hours.

The bearing is just the angle difference from the ship current location to where it started.

Let the speed be km/h

Distance covered in the first round

= 15*1

= 15km

Distance covered in the second round

=15*2

= 30 km

Angle at C = (90-80)+90

Angle at C = 10+90= 100

Let the distance between the port and the ship be c

C²= a² + b² -2abcos

C²= 15²+30²-2(15)(30)cos 100

C²= 225+900+156.28

C²= 1281.28

C= 35.8 km

Using sine formula

30/sin x= 35.8/sin 100

30/35.8 * sin 100 = sinx

0.838*0.9848= sin x

0.8253= sin x

Sin ^-1 0.8253 = x

55.62° = x

The bearing is N 55.62° W

Nick's telephone company charges $0.07 per minute for weekend calls and $0.08 per minute for calls made on weekdays. This month
DerKrebs [107]
 So pretend weekend calls is x and weekday calls are y.


the formulas is x + y = 610
                        0.07x + 0.08y = 48.05

So, x = 610 - y

Then, substitute x into the second equation.

0.07(610 - y) + 0.08y = 48.05
 42.7 - 0.07y + 0.08y = 48.05
                        0.01y = 5.35
                               y = 535


Then substitute y into the first equation.

x + 535 = 610
          x = 75

Just to be sure, substitute x and y into the second equation.

0.07(75) + 0.08(535) = 48.05
             5.25 + 42.80 = 48.05
                        48.05 = 48.05


So, on weekends, he used 75 minutes.
On weekdays, he used 535 minutes.
