A pair of shoes was regularly priced at $85 but is now on sale for $59.50. What percent discount was applied to the regular price?

  30% discount

Step-by-step explanation:

The percentage change between two values can be found by ...

  percentage change = ((new value)/(old value) -1) × 100%

  = (59.50/85.00 -1) × 100%

  = (0.7 -1) × 100%

  = -30%

A 30% discount was applied to the regular price.

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
