Josh wants to download music online. He must buy a membership for $14.
Then he can download songs for 99 cents each. Josh has $20. How many
songs can Josh buy without spending more money than he has?

6 songs

Step-by-step explanation:

It's best to start by setting up an equation equal to $20.

$14 + $.99s = $20

s being songs in this case.

First we add like terms by subtracting $14 from both sides.

$.99s = $6

Now we solve for s by dividing both sides by $.99

s = $6.06

Therefore, Josh can by 6 songs.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
