Answer:
C
Step-by-step explanation:
Rule: 6*Side (Twice)
= 6*25*25=3750
We have been given that
Luke can read 4 3/4 pages in 15 minutes.
Hence in 1 minute Luke can read 19/60 pages.
Sarah can read 1 1/2 pages in 4 minutes.
Hence, in 1 minute Sarah can read 3/8 pages.
Now, let us find how many pages they can read in 2 hours = 120 minutes.
In 2 hours Luke can read pages.
In 2 hours Sarah can read pages.
The difference in the number of pages is 45 - 38 = 7 pages.
Therefore, Sarah can read 7 more pages than Luke in 2 hours.

Answer:
b = 12 = 20.78
c = 24
Step-by-step explanation:
The sides of a 30-60-90 triangle always have the same proportion to each other. The side opposite the 30 degree angle is x, the side opposite the 60 degree angle is x and the side opposite the 90 degree angle is 2x (this side is called the hypotenuse) .
Since we know the side opposite the 30 degree angle here is 12, then we know that the side opposite the 90 degree angle is 2 times the side opposite the 30 degree angle, c = 24 units (2 x 12).
Finally, the side opposite the 60 degree angle is 12 which equals 20.78 units.
Sure the sin function is an odd function because sin (-Ф) = - sin (Ф)
Example: sin (- 30°) = - sin (30°) = -1/2
