Asixth grade science club needs $180 to pay for the tickets to a science museum. all the tickets cost the same amount. what could 180/15 mean in this context? describe two interpretations of the expression. then, find the quotient and explain what it means in each interpretation.

Step-by-step explanation:

The total amount of money needed by the sixth grade science club to a science museum is $180. Since all the tickets cost the same amount, then, 180 which is the dividend means the total amount of money needed by the sixth grade science club.

15 is the divisor and it represents the total number of tickets needed.

The quotient is the result of the division. The quotient is $12

So the quotient is the cost of one ticket.

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
