First of all we must use the same unit measure for all data, otherwise it wouldn't make sense to compare meters and kilometers.
Since one kilometer is the same as 1000 meters, we have that 920000 meters are 920 kilometers.
Now, the train travels at 230 kilometers per hour. It means that it travels 230 kilometers with each passing hour
So, after 1 hour, the train travels 230 km. After two hours, the train travels 2x230 = 460km, and so on
In general, the distance traveled after k hours is .
We want that distance to be 920, so the equation is
So, the train travels 920 kilometers (i.e. 920000 meters) in 4 hours.
Answer: X = 5.0
Step-by-step explanation:
- since these are right triangles you can use trigonometry to solve this pretty easily
- for this situation, you only have to use sine/sin
- sine/sin is
__________________________________________________________
- to start you just need to identify which side is which:
- the side that is labeled 10 is the hypotenuse
- in this case, the shared side is the opposite since you're using sin
- so, for this problem the equation is:
__________________________________________________________
- so 7.071067812 is the hypotenuse of the smaller triangle so you just do the same thing again
- start with identifying which side is which:
- as said, the side that is shared and 7.071067812 is the hypotenuse
- the side labeled x is the opposite
- so for this part, the equation is:
- so X = 5.0
