Answer:
You never gave the speed of the blue train. The path to collision is equal to 1½ circles. 1.5 x 210 meters = 315 meters I'm going to arbitrarily guess the speed of the blue train is 15 meters per minute. They are therefore approaching each other at a combined rate of 35 meters per minute. 315 / 35 = 9 minutes Answer: 9 minutes
Step-by-step explanation:
This is a proportion question. We can express this as an equation where the answer is
x:

=

From there, you can just cross-multiply and divide to get:

A tenth of 250 is 25, so this is roughly

or

, so it'll be approximately 1.7 inches on the map.

Step-by-step explanation:
Step-by-step explanation:
y = 4 when x = 8 So, 4 = 8k
k = 1/2
y = (1/2)x
Therefore, when x = 10, y = (1/2)(10) = 5
Answer:
The value if x is 0.9875.
Step-by-step explanation:
First, we have to get rid of brackets by expanding :



Next you have to collect like terms :


Lastly, you can solve x :
