Answer:c is the correct answer
Step-by-step explanation:
A repair company's charge for repairing a certain type of copy machine fits the model y = 47.38 + 0.617x
where y is the number of dollars charged and
x is the number of minutes the repair person is on the job.
Therefore, to determine the number of minutes that it would take for the cost of repair to reach $130, we would substitute y =130 into the given model. It becomes
130 = 47.38 + 0.617x
0.617x = 130 - 47.38 = 82.62
x = 82.62/0.617 = 134 minutes
Answer:
Step-by-step explanation:
<B=90-47=43
AB/BC=sin 47
BC=AB/sin 47=18/0.731=24.6 nearly
AC/AB=Tan 43
AC=18 tan 43=16.8 nearly
