Example 7 Two ships A and B leave a port P at the same
time. A travels on a bearing of 159° and
travels on a bearing of 215°. After some time,
A is 9km from P and the bearing of B from
A is 256º. Calculate the distance of B from P.
Fig. 5.15 shows the positions of P, A and B.
The arrows at P and A point northwards.

i can you with this question sweetie!

step-by-step explanation:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
