Question

diego has 90 songs on his playlist. how many songs are there for each genre ? 40% rock , 10% country , 30% hip hop , the rest is electronica

Answer 1

Answer: Rock= 36 ; Country= 9 ; Hip hop= 27 ; Electronica = 18

Step-by-step explanation:

Total number of songs= 90 songs

Percentage of rocks songs= 40%

Percentage of country songs= 10%

Percentage of hip hop songs= 30% Percentage of electronica=

100% - (40%+10%+30%)

= 100% - 80% = 20%

The number of songs for each genre will be the percentage for that genre multiplied by the total number of songs.

Number of rock songs

= 40/100 × 90

= 0.4 × 90

= 36

Number of country songs

= 10% of 90

= 10/100 × 90

= 0.1 × 90

= 9

Number of hip hop songs

= 30% of 90

= 30/100 × 90

= 0.3 × 90

= 27

Number of electronica

= 20% of 90

= 20/100 × 90

= 0.2 × 90

= 18

Answer 2

Answer:

Diego playlist has 36 songs in rock genre, 9 songs in Country genre, 27 songs in hip hop genre and 24 songs in electronica genre.

Step-by-step explanation:

Given:

Total Songs on playlist = 90

rock = 40%

country = 10%

hip hop = 30%

rest is electronica.

We need to find the number of songs in each genre.

rock = 40%

So Number of songs in rock genre = $\frac{40}{100}\times90 = 36\ songs$

country = 10%

So Number of songs in country genre = $\frac{10}{100}\times90 = 9\ songs$

hip hop = 30%

So Number of songs in hip hop genre = $\frac{30}{100}\times90 = 27\ songs$.

and rest is electronica genre.

Number of songs in electronica genre can be calculated by Subtracting Number of songs in rock genre and Number of songs in country genre and

Number of songs in hip hop genre from Total number of songs.

framing in equation form we get;

Number of songs in electronica genre = $90-30-9-27 = 24\ songs$

Hence Diego playlist has 36 songs in rock genre, 9 songs in Country genre, 27 songs in hip hop genre and 24 songs in electronica genre.
