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.

Mr. Claussen needs a total of 15 pounds of ground beef to make hamburgers for a company picnic. He finds that 2 pounds of ground
Marat540 [252]

Answer: $33.00

Step-by-step explanation:

Given

Mr. Claussen needs 15 Pounds of ground beef

It is stated that 2 pounds of beef cost $4.40

Using unitary method

1 Pound cost  \frac{4.4}{2}=\$2.2

For 15 pounds it is

\Rightarrow 15\times 2.2=\$33

Thus, he has to spend $33 for 15 pound meat

You are enclosing a rectangular garden with 180 feet of omamental fencing. The area of the garden is 1800 square feet. What are
Brut [27]

Answer:

Step-by-step explanation:

Perimeter is

P = 2L + 2W.  We are given the perimeter as 180 feet, so

180 = 2L + 2W.  Solve this for either L or W.  I chose W, no reason...

180 - 2L = 2W so

90 - L = W  Hold that thought.  We'll come back to it in a minute.

Area is

A = LW.  We are given the area as 1800 square feet, so

1800 = LW.  Sub in 90 - L for W:

1800 = L(90 - L).  Distribute to get a quadratic:

1800=90L-L^2

Get everything on one side and solve for the length by factoring:

-L^2+90L-1800=0

Factor this however you like to factor quadratics, to get the length of

L = 30 and L = 60.  First off, the length is longer than the width in general, so if we want to solve for the width, plug in 60 as L in the equation in bold print:

90 - 60 = W and

30 = W

So L = 60 and W = 30

The Candle Factory is producing a new candle. It has a radius of 3 inches and a height of 5 inches. What is the surface area of
Savatey [412]

Answer:

We are looking for the amount of wax it will take to fill up that size candle mold to make that candle. That means that we are looking for the volume of wax, and the shape is a cylinder. The volume formula for a cylinder is

For us, that will look like this:

which translates to

V = 3.14(9)(5) which gives us a volume of 141.3 cubic inches. Rounding to the nearest cubic inch is simply 141 cubic inches of wax.
