5) You randomly choose a marble from a jar. The jar contains 4 red
Dmitry [639]

the  probability of the event choosing a yellow marble is 2/9 .

<u>Step-by-step explanation:</u>

Here we have , to choose a marble from a jar. The jar contains 4 red

marbles, 10 blue marbles, 7 green marbles, and 6 yellow marbles. We need to Find the  probability of the event choosing a yellow marble . Let's find out:

According to question question we have following parameters as :

Red marbles = 4

Blue marbles  =10

Green marbles = 7

Yellow marbles = 6

Now , Probability to chose a yellow marble is :

Favorable outcomes = 6(Number of yellow marbles )

Total outcomes = 4+10+7+6 = 27( Total marbles )

Hence ,

⇒ Probability = \frac{6}{27}

⇒ Probability = \frac{2}{9}

Therefore ,  the  probability of the event choosing a yellow marble is 2/9 .

two trains leave stations 210 miles apart at the same time and travel tword each other. one train at 85 miles per hour while the
hodyreva [135]

recall your d = rt, distance = rate * time.


let's say we have two trains, A and B, A is going at 85 mph and B at 65 mph.


they are 210 miles apart and moving toward each other, at some point they will meet, when that happens, the faster train A has covered say d miles, and the slower B has covered then the slack from 210 and d, namely 210 - d.


When both trains meet, A has covered more miles than B because A is faster, however the time both have been moving, is the same, say t hours.


\bf \begin{array}{lcccl} &\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\ \cline{2-4}&\\ \textit{Train A}&d&85&t\\ \textit{Train B}&210-d&65&t \end{array}\\\\ \dotfill\\\\ \begin{cases} \boxed{d}=85t\\ 210-d=65t\\[-0.5em] \hrulefill\\ 210-\boxed{85t}=65t \end{cases} \\\\\\ 210=150t\implies \cfrac{210}{150}=t\implies \cfrac{7}{5}=t\implies \stackrel{\textit{one hour and 24 minutes}}{1\frac{2}{5}=t}

irina [24]

Answer:

12\sqrt{3} feet

Step-by-step explanation:

In a 30-60-90 triangle, the ratios of the side lengths of the triangle is 1:\sqrt{3} :2

Where 1 is the shortest leg, root(3) is the longer leg, and 2 is the hypotenuse.

First we can set x equals to the length of the original pole, and so the shorter leg has a length of x/3 and using the ratio of side lengths, we can find that:

\frac{x}{3} * \sqrt{3} = \frac{\sqrt{3} x}{3} = 12

Solving for x, we find that

x=\frac{36}{\sqrt{3} } = \frac{36 * \sqrt{3} }{\sqrt{3} * \sqrt{3} } = \frac{36  \sqrt{3} }{3} = 12\sqrt{3}

So the length of the original pole would be 12\sqrt{3} feet
