Answer:
The first one
Step-by-step explanation:
Answer: 1st train = 364 mph, 2nd train = 356.2
Step-by-step explanation:
Train 1: x + 7.8
Train 2: x
Train 1 + Train 2 = Sum
x + 7.8 + x = 720.2
7.8 + 2x = 720.2
2x = 712.4
x = 356.2
Train 1: x + 7.8
= 356.2 + 7.8
= 364
This is the 2nd time I've posted this answer... not sure why it didn't go through the first time. Let me know if you have questions. :)
Answer:
2/5
Step-by-step explanation:
To find the slope of a line segment, find the difference in y and divide by the difference in x (delta y / delta x)
Delta y: -7 - (-13) = 6
Delta x: 15 - 0 = 15
Slope = delta y / delta x
Slope = 6/15 = 2/5

Answer:
520 feet
Step-by-step explanation:
The easiest way to visualize this problem is to sketch a quick diagram.
For this problem, you are given an angle and the length of the side of a triangle. If you look at the diagram, you'll see that the length given is the opposite side of the angle given. For this situation, that means you will use the sine function (refer to SOH-CAH-TOA acronym). Then you plug in the given values and solve for x.
Hope this helps!
