Answer:
1 hour/ 34 minutes
Step-by-step explanation:
Im not sure but i think its A because you have no value to multiply 3 so you just multiply it by itself.It would be a negative because you cant divide 3 by 2.so it would be A.-x9y2.
i hope i was correct and helped if not you can go ahead and delete my answer:)
2sin²(-2490)+tan 1410=2sin²(-330-6*360)+tan (330+3*360)=
=2sin²(-330)+tan (330)=2 sin²(30-1*360)+tan (-30)=
=2sin²(30)-tan (30)=2(1/2)²-√3/3=1/2-√3/3)=(3-2√3)/6
Answer: 2 sin²(-2490)+tan (1410)=(3-2√3)/6 (≈-0.07735...)
Most likely because there are more boys than girls but there could be an odd that a girl will be in the group since there is less girls and hs;es picking at random
Answer: b. 125
