For a:
(2400*2*PI)/60(seconds) = 80 PI RAD/Sec
For b:
arc length s= radius r * central angle(in radians)
= ((80*pi*7.5)/(2*pi)
=25

Answer:
$2611.05
Step-by-step explanation:
earnings = lane rentals + concessions
<u>Friday</u>:
earnings = $842.72 +412.38 = $1255.10
<u>Saturday</u>:
We assume "down by 1/8" means the value was 1 -1/8 = 7/8 that of the previous day. Likewise, "increased by 1/2" is assumed to mean the value was 1 + 1/2 = 3/2 that of the previous day.
earnings = 7/8×$842.72 + 3/2×412.38 = $1355.95
__
Then the total earnings for both days were ...
$1255.10 +$1355.95 = $2611.05
m = -6
evaluate -m
so -m = -(-6) which would equal 6
