Buy 3 t-shirts for $24. write a proportion that gives the cost c of buying 7 t-shirts.

3 T-shirts for $24 each would be $72.00

7 T-shirts for $24 each would be  $168.00

Step-by-step explanation:

$24 x 3 = $72.00

$24 x 7 = $168.00

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)

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
