Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at a rate of 65
koban [17]

Answer:

time = 1 hour 24 minutes

Step-by-step explanation:

Given that:

Eastbound train travels at a rate of 65 miles per hour

Westbound train travels at a rate of 85 miles per hour

So speed = 65 + 85 = 150 miles per hour

Total distance = 210 miles

We have to find the time

We know that

Distance = time * speed

OR

time = distance / speed

time = 210/150

time = 1.4 hours

Or it can be written as:

time = 1 hour 24 minutes

i hope it will help you!

Solve for x. round to the nearest hundredth if necessary.
iris [78.8K]

Answer: x=11.47

Step-by-step explanation:

Given the angle of 55 degrees, you know that the adjacent side is "x" and the length of the hypotenuse is 20.

Therefore, you need to remember the following identity:

cos\alpha=\frac{adjacent}{hypotenuse}

Then, knowing that:

\alpha=55\°\\adjacent=x\\hypotenuse=20

 You need to substitute these values intocos\alpha=\frac{adjacent}{hypotenuse}:

 cos(55\°)=\frac{x}{20}

Now, you can solve for "x":

20*cos(55\°)=x\\x=11.471

Rounded to the nearest hundreth:

x=11.47
