If each playlist is an average of 45 minutes long the linear function m(x) = 0.75x could be used to find out how many playlist you need to create .
how many hours of music are there on 4 playlists ?

3 hours

Step-by-step explanation:

0.75*4 = 3.00

45*4=180     180/60=3    180 minutes =3 hours

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
