Answer:

It had flown 2620 ft along the diagonal.

Step-by-step explanation:

When the plane is taking off it forms we can form a triangle with it's height, horizontal distance and diagonal distance, which can be seen in the attached drawing. We can use the sine relation on the right triangle to determine "x", as shown below:

sin(11°) = 500/x

x*sin(11) = 500

x = 500/[sin(11)] = 2620 ft

It had flown 2620 ft along the diagonal.

10 mL = ____________ L ( 1L = 1000 ml
DENIUS [597]

Solution:

<u>Note that:</u>

  • 1 L = 1000 ml

<u>Using the clue above, let's solve each problem.</u>

  • 10 mL        =        10/1,000 L           =           0.01 L
  • 1.2 L          =     1.2 x 1,000 mL        =       1,200 mL
  • 3,500 mL =     3,500/1,000 L        =           3.5 L
  • 4 L            =       4 x 1,000 mL        =       4,000 mL
  • 230 mL    =        230/1,000 L         =           0.23 L
  • 6.21 L       =     6.21 x 1,000 mL      =       6,210 mL
