Answer:
The Answer is D
Step-by-step explanation:
"He starts both trains at the same time. Train A returns to its starting point every 12 seconds and Train B returns to its starting point every 9 seconds". Basically, what you need to do is find the least common multiple. The least common multiple of 12 and 9 is 36, so the least amount of time, in seconds, that both trains will arrive at the starting points at the same time is 36 seconds.
Answer:
Step-by-step explanation:
b=bench
852=b+(b-98) since the table is less than the bench by 98$
852-b=b-98
950-b=b
950=2b
475=b
Answer:
Step-by-step explanation:
angle 1= 50 degrees
x angle=50 degrees
cross multiply and you get and you get <u><em>1</em></u> as your answer
15) factor out cos: cos(x)(sin(x)+1)=0
Now this is true when either cos(x)=0 (x=pi/2 and 3pi/2)
Or when sin(x)=-1 (x=3pi/2)
So it's solutions are pi/2 and 3pi/2
