Solve for F
Subtract 273 from both sides
Multiply through by 
Add 32 to both sides
The numbers are 11 and 6.
Lovely.
The car is traveling at 95 km/h, and the train is at 75 km/h.
Remember the train is 1 km long.
a)
With respect to the train the car is not moving as much as 75 km/h.
The car with respect to the train is moving as much as 95 - 75 = 20 km/h
Recall the train is 1 km long.
Time to cover the 1km long train = Distance / speed = 1 / 20 = (1/20) hour.
= (1/20)*60 minutes = 3 minutes.
So the car would pass the train in 3 minutes.
b)
Now if they are traveling in opposite directions;
the car with respect to the train = 75 + 95 = 170 km/h
Time to cover the 1km long train = Distance / speed = 1 / 170 = (1/170) hour.
<span>= (1/170)*60 minutes = (6/17) minutes
</span>
= (6/17)*60 seconds = 360/17 seconds ≈ 21.176 seconds.
Answer:
For number 2 It would be 10x+12=29
For number 3 Try -37 Because i'm ending up with -36
Step-by-step explanation:
If the 2 was outside of the parenthesis you would multiply both numbers in the parenthesis
Answer:
-4.41
Step-by-step explanation:
208° is a 3rd-quadrant angle, so its x-coordinate will be negative. Your calculator can tell you that 5 times the cosine of this angle is -4.41, or you can refer to a diagram.
