\(\frac{4}{3} y-1 =\frac{3}{4}\\ \frac{4}{3} y-1+1 =\frac{3}{4}+1\\ \frac{4}{3} y=\frac{7}{4}\\ \frac{4}{3}*\frac{3}{4} y=\frac{7}{4}*\frac{3}{4}\\ y=\frac{21}{16}\\ y=1\frac{5}{16}\\\)

what is the square root of pi

\(\sqrt{\pi} = \Gamma{ \left( \frac12 \right) }\)

Why is our pi so short???     I don't know, here are some possibilities

1) It is a short crust pie.

2) When it was a little pie it did not have enough growth hormone.

3) Someone put books on its circumference and it got squashed.

Anyone have more ideas??

Do you mean the 5th root of 9 cubed?

\(\sqrt[5]{9^3}=(9^3)^{1/5}=9^{3/5}=9^{0.6}\)

Now you can just enter it into a calc.  

Is that what you wanted?

Since the median age is less than the 2 known ages it follows that the twins are the youngest.

Let the age of the twins be x

So the ages from youngest to oldest are    x, x, 16, 19

The median age is the average ot hte two middle ages and it equals 14

so

(x+16)/2=14

x+16=28

x=28-16

x=12

The twins are 12 years old.

That is so awesome that you got to go to Cornwall Miss Melody! I watch Doc Martin every Tuesday night and it is awesome! I'm a huge fan of his show! I also watch Doctor Blake which is an Australia production of a police surgen who's as good a detective than he is at his normal profession. But then you most probably watch it all the time. I just came on to say hi and see how you're all doing, you know, in my absence,  , but anyway, I gotta go now, but it was nice to see you all again. Or at least read you all again, ha, ha... well, um, bye.

How do I factorise 3x^2+2x = x(3x+2)

what is 1.6666666666666667 in fraction form

\(\begin{array}{rclcl} 100 & \times & 1.66\overline{6} &=& 166.\overline{6}\\ -1 & \times & 1.\overline{6} &=& 1.\overline{6} \\ \hline 99 & \times & 1.\overline{6} &=& 165\\ 1.\overline{6} &=& \frac{165}{99} \\ &=& \frac{55}{33} \\ &=& \frac{5}{3} \\ \end{array}\)

Hang on, you will probably need to pay for my return 1st class flight and 5 star accomodation for a week or 2 or 3  but I am sure i can make it worth your while.

What say you?

Yes of course, I have nothing better to do :)))

Ugh!!!!!!!!!!!!!!

1.66666666666666666667=1 2/3 or 5/3.

Density=mass/volume. Gold has a density of 19.3 grams per cubic centimeter. what is the mass in kilograms of a bar of gold that measures 10 centimeters by 4 centimeters by 5 centimeters?

Volume of the bar=10 X 4 X 5=200 cm^3

Mass=200 X 19.3=3,860 grams

Mass=3.86 Kilograms

How many half-lives does it take for 6 x 1023 atoms of a radioactive nuclide to completely disappear?

2^x=6 X 10^23

x=79 half-lives

Do you think both types of shoes are 50% off? Or just the cheaper ones? It sounds to me, that only the cheaper ones are on 50% sale, but not the more expensive ones. If that's the case, then your answer will be different. If my hunch is right, the total cost to her would be:($43 X 2) + ($36/2 X 2)=$122.00.

3-(3/4)=(5/6)w subtract 3/4 from left side

2 1/4=5/6w turn the left hand side into improper fraction

9/4=5/6w

5/6w=9/4 multiply both sides by 6/5

w=9/4 X 6/5

w=54/20 divides right hand side by 2

w=27/10

Just a "run of the mill" ratio!!!.

300000000 × 521000000000000 =1.563 × 10^23,

So, what's so "chemical" about two large numbers?

Yes, the pattern does still hold.

You just have not thought of the right pattern :))

Yes   root3*root3 = root9 = 3    which is rational

\(-2x^2+3x-4=0\\ \mbox{divide through by -2}\\ x^2-\frac{3}{2}\;x+2=0\\ x^2-\frac{3}{2}\;x=-2\\ x^2-\frac{3}{2}\;x+\left(\frac{3}{4}\right)^2=-2+\left(\frac{3}{4}\right)^2\\ \left(x-\frac{3}{4}\right)^2=\frac{-23}{16}\\ \mbox{No solution in the real number system} \)

How many Joules of energy are there in one photon of yellow light whose wavelength is 630 nanometers?

W=c/v, c=speed of light, v=frequency

6.3 X 10^-7=3 X 10^8/v

v=3 X 10^8 / 6.3 X 10^-7

v=4.76 X 10^14 Hz-frequency of the yellow light.

E=hv, h=Planck's constant,

E=(4.76 X 10^14)Hz X 6.62607×10^-34 J s 

E=3.15401×10^-19 Joules- the energy of a single photon of yellow light.

F=ma

m=f/a

10/2

m=5

what is the radical of 48 ?

\(\sqrt{48}\)

I assume you want this simplified?

Tell me, what is the largest square number that goes into 48?

If you cannot tell me the largest one then tell me ANY one!   :)
