V = IR

   =3.2*.0480 = 0.1536 v = voltage drop

b)   3.2*.096 = 0.3072 voltage drop        

       .3072-.1536 = .1536 volts less available to appliance when using the second cord

Wow thats pretty good

b^2 - 4ac     if it is lees thatn zero there are two conjugate irrational roots 

                    if it equals zero thee are two real identical root

                    if it is > zero there are two different roots

the anser 14

= 8 / sqrt(3)/2  =  16 / sqrt(3)  or   16 \(\sqrt{3}\) / 3

by turning a decmail into a fraction LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL LOL!!!!!!!!!!!!!!!!!!!!!!!!!

what is 0.5787037037 as a simplest fraction?

\(\Large0.5787037037 =\frac{5787037037 }{10^{10}}=\frac{12107\times477991}{10^{10}}\)

  !

Thank you Guest!
How did you do that?

= 125 / 216 =0.578703703703703......etc.

if 1+2=x*23^900+2, what's x?

\(1+2=x\times 23^{900}+2\)

\(x\times 23^{900}=1\)

\(x=\frac{1}{23^{900}}\)

\(x=23^{-900}\)

You divide 9/5, and the first number you get will be the whole number, the bottom number will be the numerator of the fraction (the top) and the number you are dividing (is on the outside of the box) will be the denominator (bottom number). 

Or you can see how many times 5 goes into 9, and whatever the number goes into it (doesn't have to go straight in) will be the whole number. Then, you subtract 9 and the number that is your whole number times 5, and whatever you get will be your numerator. The denominator will be the bottom number of 9/5. 

There you go! That is how you find 9/5 as a mixed number!

Brad bought a computer for $453 and a printer for $96. So Brad spent a total of $453 + $96 = $549.

Maria bought a television for $399 and a DVD player for $148. So Maria spent a total of $399 + $148 = $547.

Brad spent $549. Maria spent $547.

Which is greater, $549 or $547 ?

one divided by six= ONE SIXTH

I don't know how to make an "inequality" out of this, but I can tell you Elliot's height exactly.

Sam is 5 feet tall. Sam is 2 feet taller than Elliot.

5 + 2 = Elliot's height.

7 feet = Elliot's height.

What the heck?

 thank you

Disprove: If p is prime, then (2^p)-1 is also prime. Help?

Well that was easy :)

I only need to find one time where 2^p-1 is not prime and then it will be disproven!

I just tried them one at a time and found

2^11 = 2048

factor(3047) = 11*277                 I used the web2.0calculator for this :)

so

2^11-1 = 11*277 so it is not prime

Hence

If p is prime, then (2^p)-1 is also prime, has been disproven.  :)

The button that looks like a check mark with a long/extra line.

\((\frac{7 + (2 + 6) 2 ÷ 4 ⋅ 1}{2})^{4}\)

Just follow the orders of operation: Parenthesees, Exponents, Multiplication/Division, Addtion/Subtraction

\(= (\frac{7 + (8) 2 ÷ 4 ⋅ 1}{2})^{4}\)

\(=(\frac{7 + 16 ÷ 4 ⋅ 1}{2})^{4}\)

\(=(\frac{7 + 4 ⋅ 1}{2})^{4}\)

\(=(\frac{7 + 4}{2})^{4}\)

\(=(\frac{11}{2})^{4}\)

\(=(5.5)^{4}\)

\(=\frac{14641}{16} = 915.0625\)

In a circle with a radius of 26.9 m, an arc is intercepted by a central angle of 9π/5 radians.

What is the arc length?

Use 3.14 for π and round your final answer to the nearest hundredth.

Why do you need HELP IMMEDIATELY ?

Perhaps you are doing a test and want the answer now ?

Do you realize how rude it is to say this?  There was not even a please.

Hint:  How many radians in a revolution?

What is the circumference of the circle

What fraction of the circumference to you have?

First we need to find the length of the extra piece of triangle that isn't drawn on the picture, the part that is behind the man. Let's call that part "x." Two similar triangles are formed. The first one is formed by the man, the line of sight, and the ground, x. The second one is formed by the surveying pole, the line of sight, and the ground, x+10. Since these triangles are similar, the height of the man over the length of his ground equals the height of the pole over the length of its ground.

\(\frac{6}{x}=\frac{7}{x+10}\)

6(x+10)=7x

6x+60=7x

60=x

Now that we know x, we can make two different similar triangles. The first one is formed by the mountain, the line of sight, and the ground, c+60. The second is formed by the man, the line of sight, and the ground, 60.

So

\(\frac{m}{c+60}=\frac{6}{60}\)

Where "m" is the height of the mountain. Before we put "c" in, we have to convert it to feet. 5 miles = 5(5280) ft = 26400 ft.

\(\frac{m}{26400+60}=\frac{6}{60}\)

\(\frac{m}{26460}=\frac{6}{60}\)

m = 0.1(26460) = 2,646 ft
