PLEASE HELP IMMEDIATELY, I NEED A RESPONSE TONIGHT!!!

Mathematics
1 answer:
Natasha2012 [34]2 years ago

Answer:

Step-by-step explanation:

The key fact is what are the trains doing: are they travelling toward one another or away from each other

Away from each other.

Train A has gone 50 km in 1 hour

Train B has gone 65 km in 1 hour.

They started off being 200 km apart

So their distance now is 50 + 65 + 200 = 315

Towards each other

This time they are eating into the 200 km

So you subtract

200 - 65 - 50 = 200 - 115 = 85 km.

Both trains are travelling in the same direct -- in B's direction

B - 65 + 50

200 - 15

185 km

Both trains are travelling in As direction

A - 50 + 65

200 + 15 = 215

The tricky part of this is which train is going in what direction?

As you can see, You have covered A C and D

The only one can't get is 115 (of course 315 didn't show up either).

It is either a or b. since 8-2 does not equal 14, and 8+2 does not equal 14. I think it is most likely to be a though.

Think about converting 48% to an equivalent fraction in reduced form. If the denominator is 25, what is the numerator?
bulgar [2K]

Answer:

the numerator is 12

Step-by-step explanation:

since 48 is a percent, it would be put as 48/100 as a fraction. since both the numerator and denominator are divisible by 4, you can reduce the fraction into 12/25. Since the question is asking what the numerator was when the denominator was 25, the answer is 12.
