Harrison has 50 cds in his music collection. if 10% of the cds are country music and 60% are pop music, how many cds are other types of music?

The number of country music CDs is 5  and  

The number of pop music CDs is 30

Step-by-step explanation:

Given as :

The total number of CDs does Harrison has in his music collection = 50

The percentage of country music CDs = 10%

The percentage of pop music CDs = 60%

Let The number of country music CDs = x

And The number of pop music CDs  = y

So , x = 10% of 50

I.e   x = 0.1 × 50

∴   x = 5

Again ,

     y = 60% of 50

I.e  y = 0.6 × 50

∴    y = 30

Hence The number of country music CDs is 5  and  The number of pop music CDs is 30  . Answer

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
