David's optometrist sold him a bottle of eyeglass cleaner containing 30 ml of glasscleaning solution. assuming there are 20 drop
Furkat [3]
Each complete cleaning requires 6 drops of cleaner.  Let's convert that to ml:

6 drops     1 ml              3 ml cleaner
----------- * ------------- = ------------------- = 0.3 ml cleaner per cleaning
                 20 drops      10 cleanings

Recall that 1 bottle contains 30 ml cleaning fluid.

How many cleanings is one bottle of fluid good for?

1 bottle       0.3 ml
----------- = -----------   => x = 100 cleanings/bottle
      x            30 ml

A ship travels due west for 90 miles and turns to travel 80 miles in the northwest direction at a 120 degree angle. How far is t
adoni [48]
We breakdown the components of the distances.
(1) 90 miles west.
                          x - component = -90 miles
                          y - component = 0 miles
(2) 80 miles, northwest (120°)
                          x - component = (80 miles)*(sin 30°) = 40 miles (negative)
                          y - component =(80 miles)*(cos 30°) = 69.282 miles (positive)

Solve for the distance,
                                 √(-90 - - 40)² + (69.282 miles)²  = <em>147.31 miles</em>
