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).

Hello army :,) Here’s the answer:


B)
(3.19 * 10^8)/(8.23 * 10^5) = 3.19/8.23 * 10^8/10^5
= 3.19/8.23 * 10^3 = 0.387606318 * 10^3
= 387.606318

sam rolls 3 standard fair dice. that probability that the three numbers rolled on the dice are the sides of a triangle is , wher
mart [117]

The required probability for three numbers rolled on the dice are the sides of a triangle is 31/36.

<h3>What is probability?</h3>

The area of mathematics known as probability studies potential outcomes of events as well as their relative probabilities and distributions. It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability.

Here,

When three dice are rolled, there are 63=216 possible outcomes, or triplets (x, y, z).

Once more, in a triangle, any two sides added together are larger than the third side, or (x+y)>z.

As a result, 186 outcomes or triplets are possible and satisfy this property.

Hence, the required probability is 186/216=31/36.

The required probability is 31/36 for three dice rolls to produce triangle sides.

Solve the equation v+5/-9 - 4 = -6/8
tamaranim1 [39]
First you simplify both sides of the equation to make v+-41/9=-3/4.

Then add -41/9 to both sides to get the answer which is 137/36

v=137/36

Please help me with this.
Valentin [98]

The correct proportion of the corresponding sides is 2 : 3

<h3>How to determine the proportion?</h3>

From the question, we understand that the shapes are similar.

This means that:

Ratio = GHIJ : KLMN

From the figure, we have:

GH = 6 and KL = 9

So, we have:

Ratio = 6 : 9

Simplify the ratio

Ratio = 2 : 3

Hence, the correct proportion of the corresponding sides is 2 : 3
