Trey had 440 songs on his mp3 player.now he has 473 songs.what is the percent of increase in the number of songs on his mp3 play

olga55 [171]

Answer:

There is 7.5% increase in the number of songs on his mp3 player.

Step-by-step explanation:

Original Songs in mp3= 440 songs

Final Songs in mp3= 473 songs

We need to find percent of increase in the number of songs on his mp3 player.

The formula used is: $Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100$

Now putting values and finding percent of increase

$Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100\\Percent \ of \ increase = \frac{473-440}{440} \times 100\\Percent \ of \ increase = 7.5\%$

So, there is 7.5% increase in the number of songs on his mp3 player.

Solve for the missing variable. Round to the nearest tenth.

Juliette [100K]

Answer:

x = 4
y ≈ 10.8

Step-by-step explanation:

In this geometry, the triangles are similar. That means corresponding sides are proportional:

short side/long side = x/10 = 10/25

x = 100/25 = 4 . . . . multiply by 10

hypotenuse/short side = y/x = (x+25)/y

y² = 4(29) = 116 . . . . . use 4 for x; cross multiply

y = √116 ≈ 10.8
