When voting for Homecoming Queen, 3 out of 5 students voted for Nancy. If there are 270 students who voted, how many of them voted for Nancy?

162

Step-by-step explanation:

If 3 out of 5 students voted for Nancy, then 3/5ths of the voters voted for Nancy. If we multiply 270×3/5, we get 162. Hope this answer helps.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

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
