The side = sqrt(200) m    ..... and the diagonal  = sqrt(2) * sqrt(200) = sqrt(400) = 20 m

tan (7°) = h / 5      where h is the height....rearrange

h = 5 tan(7°)  =   about  0.614 mi   =  1  mile  [rounded to the nearest mile]

What's the question  ????

(x^2-4x+3) + (3x^2-3x-5)

Line these up  like this :

       x^2   -  4x     +  3

+   [3x^2  -  3x    -    5 ]        Now, add as you normally would

4x ^2    -   7x     -   2          and that's your result

15000 / 3  =    5000 frs per day   x 5 days  =  25000 frs

1 + 1/3 L  =  4/3 L      and there are 10 dL in each L......so we have 10 *4/3   =  40/3 dL

And 2 + 1/2  dL  =   5/2 dL

So....the number of cakes she can bake  =

(40 / 3 )  /   (5 / 2)   =

(40 / 3)  * (2 / 5)   =

80 / 15   =

About 5 whole cakes

the square root is

15.2315462117278166

Yesssss........ What do you need?

12 +  h = c

9 + a =  b

2+2=4

(4x2) + (6/3) – 5 =

8  +  2   - 5   =

10 - 5   =

5

25<3x+4+9x-6    simplify the right side

25 < 13x - 2      add 2 to both sides

27 < 13x           divide both sides by 13

27 / 13  <   x

500=0.43*x^1.9       didvide both sides by 0.43

[ 500 / 0.43 ]  =  x^(1.9)       take the log of both sides

log [ 500 / 0.43 ]  = logx^1.9       and we can write

[ log 500 / 0.43 ] = 1.9 log x       divide both sides by 19

[ log 500 / 0.43] / 1.9           and this says that

10^ ( log ( 500 /  0.43) / 1.9 )   = x  = about  41.06

The volume is given by :

V  = (4/3) * (3.14) * (4.7)^3      ...      your answer should be in cubic units

18m = w

And that's your equation......

33 / 20      is in its simplest form

30.25%  =   .3025    =   3025 / 10,000  = 121 / 400

Slope =  [ Subtract y's in some order ] / [ Subtract x's in same order]  ........so we have

[4 - 2 ] /  [  3 - 1 ]    =   

 2 / 2   =

1 

And that's the slope of the line

7-2n=n-14       add 2n, 14 to both sides

21  = 3n         divide both sides by 3

7 = n

3x-y=-5

3x+5=y

Notice that when we rearrange the second equation, we get

3x - y  = -5  

And this is the same as the first  equation.......thus......thus sytsem has infinite solutions.......!!!!

Thanks I cant shut it down because the firewall thing is blocked to.

Is there any thing else that cant hlep me ?

to do that you will have to have super strength.
