Two competing james each offer childcare while parents work out gym a charges nine dollars per hour of childcare jim b charges $0.75 per five minutes of childcare which comparison of the child care cost is accurate

Both are the same.

Step-by-step explanation:

0.75/5 mins

5*12 = 60 min = 1 hour

(0.75*12)/(5*12) = 9$/Hour

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
