Total number of songs in Julie's MP3 player = 860
Percentage of rap songs in Julie's MP3 player = 20%
Then
Number of rap songs in Julie's MP3 player = (20/100) * 860
= 860/5
= 172
Percentage of R&B songs in Julie's MP3 player = 15%
Then
Number of R&B songs in Julie's MP3 player = (15/100) * 860
= 1290/10
= 129
So
The number of other types of songs in Julie's MP3 player = 860 - (172 + 129)
= 860 - 301
= 559
So the number of other types of songs in Julie's MP3 player was 559.

Step-by-step explanation:
20%=0.2
0.2 times 20 will give you the answer 4
The common factors are 1 and 5.
Answer:
Step-by-step explanation:
The chord and the segment between the centers form the diagonals of a kite with each pair of side being the radius of the circles.
As we know the long diagonal bisects the shorter one and they are perpendicular.
<u>Using Pythagorean, lets find the distance between the center of a greater circle and the chord:</u>
- 52² - (40/2)² = 2304 ⇒ √2304 = 48 cm
<u>The distance from the center of smaller circle and the chord is:</u>
<u>Now using Pythagorean again, find the radius of the smaller circle:</u>
- 15² + (40/2)² = 625 ⇒ √625 = 25 cm
The answer is b. There is a picture of the graphed function: y=3(1/2)^x
