Francine uses \dfrac23 32 start fraction, 2, divided by, 3, end fraction cup of pineapple juice for every \dfrac13 31 start fraction, 1, divided by, 3, end fraction cup of orange juice to make a smoothie. enter the number of cups of pineapple juice francine uses for 111 cup of orange juice.

→Number of cups of pineapple juice used in making smoothie=

→Number of cups of orange juice used in making smoothie =

→

→ Number of cups of pineapple juice = 2 ×Number of cups of orange juice

                                                                             ..................(A)

As given, Number of cups of Orange juice=111 cups

Applying the above result, i.e A, which gives

→Number of cups of pineapple juice= 2×111=222 cups

12*c

step-by-step explanation:

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
