Amount charged for downloading individual songs = x dollars
Amount charged for downloading an entire album = y dollars
In respect to person A:
6x + 2y = 25.92
3x + y = 12.96
y = 12.96 - 3x
In respect to person B:
4x + 3y = 33.93
Putting the value of y from the first equation in the second, we get
4x + 3(12.96 - 3x) = 33.93
4x + 38.88 - 9x = 33.93
- 5x = - 4.95
x = 0.99 dollars
Putting the value of x in the first equation, we get
y = 12.96 - 3x
= 12.96 - 2.97
= 9.99 dollars
Answer:
201.1 radians per minute
Step-by-step explanation:
The formula for Angular speed of tires in radians per minute =
1 revolutions per minute = 2π rad/min
32 revolutions per minute = x
x = 32 revolutions per minutes × 2 π radians per minute
x = 201.06192983 radians per minute
Approximately
x = 201.1 radians per minute
Therefore, the angular speed of the tires in radians per minute is 201.1 radians per minute
4 over 10, 8 over 20, and Two-fifths.
