I don't understand the words coming out of your mouth......LOL!!!!!!

My name is Happy7

And 81/4=20 1/4!  And 20.25!

Thanks, happy7....!!!!

0.8,80%,8/10

So, I believe we have  ...   (1/4)(4x + 15) = 24      muliply both sides by 4

4x + 15 = 96      subtract 15 from both sides

4x = 81              diivide both sides by 4

x = 81 / 4

Correct, Tiddle  !!!!

tan 3x = 1

The tangent is equal to 1 at pi/4, 5pi/4, 9pi/4, 13pi/4, 17pi/4 and  21pi/4

Dividing each by 3 we have

pi/12, 5pi/12, 9pi/12 (3pi/4), 13pi/12, 17pi/12 and 21pi/12

Yeah......ya' gotta' watch them sneaky teachers..........!!!!!

I believe it is 0.8

I can't read that good

Multiply numerator/denominator then simplify if needed

Yes, I suspected that the formula might be based off the area of any triangle whose perpendicular height is known (1/2*bh)

Anyway, Thanks

See?  I told you!

The n'th triangular number is given by n(n+1)/2

The sum of the first n triangular numbers is n(n+1)(n+2)/6

.

In this problem x has been raised to the power of spaceducks-1, so your final answer should be Mel Brooks.

Hope this helped :)

2pi in radians is the same as 360 degrees, and you have got tan 3x, so we have to triple the range; from 0 to 1080 degrees.

All we have to do then is to find the first solution, which would be arctan(1), then, we draw a CAST diagram, with the line running from the bottom left to top right quadrants, with the angle formed with the x axis being arctan(1).

Then, we go around the line created looking at the roots 3 times (as it's 3x).

There should be six roots, which we then divide by 3 to calculate what x would be.

Hope this helped!

I'm not good with this.....but I bet Alan could help.....either you can wait for him or shoot him a message....he's great at this for what I've seen!

Want to know how I know you are not a book?

Books don't have brains.

Books don't have hands.

Books get told what to say over and over again.

Good try, buddy.

No....but you should focus on books sometimes!

Like I know about old fashioned scales.......

Yes except you are best to keep g on the left and take 39 frm both sides.

equations must stay balanced.  Like old fashioned scales. :)

I mean.....the calc wont do that

Taking away negative is simply adding

So, we can say....

g+39=75

I like to turn everything around

75-39=g

75-39=26

g=26

26+39=75

26-(-39)=75

If by weight you mean mass, which is a common fallacy, the formula for calculating mass in a physics context is:

m= F/a (rearranged from F = m*a, with F being the force, a being the acceleration and m being the mass.)

Also, mass can be derived from m = V/D (where V is the volume and D is the density of the material which the object is made from)

But if you mean weight as in "physics" weight, expressed in newtons,

w = m*g (where w is the weight, m is the mass and g is the gravitational force exerted on the object in question by, say a planet, planetoid, or another astrological body; on Earth g is 9.8 and in deep space g is 0, hence the phenomenon, weightlessness).
