Find the four rational numbers and irrational numbers between 2/5 and 5/6
Savatey [412]
The four?

Of course there are an infinite number of rationals between any two different real numbers, as well as an even bigger infinite number of irrationals.

The average will be between the numbers:

\frac 1 2 (\frac 2 5 + \frac 5 6) = \dfrac{37}{60}

That's a lot of work to get a number in between.  We can just see

\frac 1 2
is between the two numbers.

The mediant, or freshman addition, will always be in between:

\dfrac{2 + 5}{5 + 6} = \dfrac{7}{11}

2/5=.4 and 5/6 is about .83, so

.6 = \frac{6}{10}

is in between as is .7, .41, .530940394 and as many rationals as we care to generate.

To get irrationals we could just add a teeny irrational to the ones we just generated, like \frac{6}{10} + \frac{\pi}{100}

We could just change that denominator a bit and get as many as we like.

But let's get some square roots.  The geometric mean will be between

\sqrt{ \dfrac 2 5 \cdot \dfrac 5 6 } = \dfrac{1}{\sqrt{3}}


That's the tangent from one of trig's biggest cliches, but I digress.  It's in between.

While we're on trig cliches, 

\dfrac{1}{\sqrt{2}}

is in between as well.

Keeping with the trig theme, also in between are

\dfrac{\pi} 6

and

\dfrac{\pi}{4}


the angles associated with the some of the above trig function values.

We could obviously go on as long as we cared to.

Which statement best defines the two quantities that are measured to find the rate at which an airplane descends? A) The quantit
Schach [20]

The <em>correct answer</em> is:


C) The quantity of distance measured in feet depends on the quantity of time measured in minutes.


Explanation:


The rate of an airplane's descent would be found using the distance it descends and the amount of time that takes.


In this situation, the amount of time that passes causes the distance the plane descends to change; this means that the distance depends on the time.

Please help I don’t get this at all
igor_vitrenko [27]

Answer:

11.82 kilometers in Luis's journey in total

Step-by-step explanation:

As per the statement:

To visit his grandmother

Distance Luis takes a train 6.37 kilometers

Distance  Luis takes a car 5.45 kilometers.

We have to find the total distance.

\text{Total distance} = \text{distance by train}+\text{distance by car}

Substitute the given values we have;

\text{Total distance Lui's journey} = 6.37+5.45 = 11.82 km

Therefore, 11.82 kilometers in Luis's journey in total
