Answer:
45:15 turned into a fraction =1/3
Step-by-step explanation:
Each song downloaded costs 3 points
each video costs 40 points
total of 999 points
if each song cost 3 points and she has 999 points to use she can download 333 songs at max
The minute hand has swept through 46 minutes on the clock. You have to set up a ratio to solve this:

You can compare the 60 minutes on a clock to 360 degrees because 60 minutes on a clock is one whole rotation. So then, you cross multiply and simplify:

Therefore, the minute hand has swept through an angle with a measure of 276 degrees.
Set the equations equal to each other
Subtract x from both sides
Divide both sides by -4
x=-1/2
