The ratio of pop songs to rock songs you download is 5:4, and 40 are pop songs. You want to find out how many rock songs there are.
First, add the ratios together: 5+4=9. This means that 9 will be your denominator, so 5/9 songs are pop and 4/9 songs are rock.
Now you know that pop songs account for 5/9 of the songs, this means that 40 is 5/9 of the total songs.
To find out how much 4/9 is, you need to divide 40 by 5 to get 1/9 and times that number by 4 to get 4/9:
40÷5=8×4=32 songs are rock songs

B. YES
C: YES
D: NO
Step-by-step explanation:
For the given geometric sequence, we have:
So the correct option is B.
<h3>
Which is the recursive formula?</h3>
Here we have the geometric sequence:
To get the initial value of the geometric sequence, we just need to replace n by 1, so we get:
Now, notice that the common ratio is (-1/3), this means that each term of the sequence is (-1/3) times the previous term.
Then the correct option is B.
