The triangle is an equilateral triangle -- which also makes it equiangular.

Since there are 180° in a triangle, how many degrees are in each angle?   _______

Also, since there are 180° on each side of a line, after you subtract the number of degrees in the angle of the triangle, how many degrees are left for the external angle?   ________

If it's the question that I found, I could certainly be wrong; but I arrived at 2 for the answer, not 1. (Again -- my answer could be wrong ...)

I have another method :)

$$cos\theta+isin\theta = e^{i\theta}\\\\$$ 

where theta is in radians

$$\\148^0=\frac{148\pi}{180}\; radians\\\\
11^0=\frac{11\pi}{180}\; radians\\\\$$

Given Z = 2(cos 148º + isin 148º) and W = 5(cos 11º + isin 11º), find and simplify Z divided by W.

becomes  

$$\\\dfrac{2e^{(148\pi/180)i}}{5e^{(11\pi/180)i}}\\\\
=0.4e^{[(148\pi/180)-(11\pi/180)]i}\\\\$$

$$\left({\frac{{\mathtt{148}}{\mathtt{\,\times\,}}{\mathtt{\pi}}}{{\mathtt{180}}}}\right){\mathtt{\,-\,}}\left({\frac{{\mathtt{11}}{\mathtt{\,\times\,}}{\mathtt{\pi}}}{{\mathtt{180}}}}\right) = {\mathtt{2.391\: \!101\: \!075\: \!232\: \!231\: \!5}}$$

=0.4cos (2.3911010752322315) +0.4* isin(2.3911010752322315) 

remember this is in radians.

= -0.2925 + 0.2728i

=  -0.29 + 0.27i

I think that method is correct. 

n/20  =  4

Multiply both sides by 20:

20(n/20)  =  20(4)

             n  =  80

Amount Spent = 3(2.45) + (1)(2.59) + (4)(0.79)

Divide 2710 by three, because when your mutilply and number by a number, you will get your quotient, which in this case is 2710. 2710/3 is 903 1/3

If the two points are (x1, y1) and (x1, y2), the slope of the straight line that passes through those two points is:  m  =  (y2 - y1) / (x2 - x1)

If (x1, y1) = (-1, -1) and (x2, y2) = (2, 8), then

     m  =  (8 - -1) / (2 - -1)  =  9/3  =  3

PEMDAS, like Melody said is needed. So, exponents and parenthesis. -3^2 is 9. 9*2 is 18. Now, remember pemdas. Do not add 4. First, do 4/-2. That will get you -2. 18+-2 is 16 like Melody said.

The quick answer is that it is the square of the correlation coefficent.

192  =  64·3

(192)^(1/3)  =  (64)^(1/3)·(3)^(1/3)  =  4·(3)^(1/3)

Dude! Just use the calculator on the CALCULATOR website.

Archimedes, by measuring inscribed polygons (insided a circle) and circumscribed polygons (around a circle) pinned the value of pi between 3 1/7 and 3 10/71.

3 1/7     = 3/142857 ...

pi           =  3.1415926535...

3 10/71  =  3/14084507 ...

Many, many centuries later, pi because identified with infinite series, so now pi is calculated with computers.

$$\\\frac{d}{dx}lnx=\frac{1}{x}\\\\
\frac{d}{dx} \;8 = 0\\\\\\
$So the answer is $\frac{1}{x}$$

Yes  that is true but there is not enough time for a second person to check all answers.

The ticks are more an indication that someone has  given a genuine answer. (or at least genuinely attempted to)

The asker should not automatically assume that the answer is correct, even if it has been ticked.  

It is up to the asker to decide if the answer is to be accepted or rejected.  Askers (and other people)  are always welcome to question what we write.  

We really like people to interact with us.

Here it is.....

0.000000000000000000000000008756510762696520338488732800739166037

So the ratio od R to G is

7.5:5

15:10

3:2

This was meant to be a table with borders but I can't get the borders to print  

Jerry has a box contained red, blue, and green markers. The ratio of red markers to blue markers is 5:2. The ratio of blue to green markers is 3:5. What is the ratio of red markers to green markers?

Note, that for every 7 red and blue markers, 2  are blue and 5 are red

So, for every  6 blue markers, 15 are red

And for every 8 blue and green markers,  3 are blue and 5 are green

So, for every 6 blue markers, 10 are green.

So, the ratio of red markers to green is 15 : 10    or just 3 : 2

I think this would be an example of the expanded property, if there is such thing. Sorry, I don't really know this! I am truly sorry. :(

Here's another way to see this without doing much math.

If the perimeter is 42, each side is 14.  And this is 2 more than 3 times the original length.

So, subtracting 2 from a side = 12.

And this is 3 times the original length.......so the original length was 4.

Can you rephrase the question? I got lost ...

Is your question, where is the square root button on this calculator?

There is a square root (√) button.

The rule is:        n² + 3

First term:       (1)² + 3

Second term:  (2)² + 3

Third term:      (3)² + 3

I don't know what you mean by "factor out in 3"?

Are you asking:  How do you factor  24x³ + 375 ?

Sorry to say that this answer was wrong. Can you see if there was another answer to this possibly?
