Simplify<br> 21x^6 y^5<br> 14x^2y^9
PIT_PIT [208]

Answer:

\frac{3x^{4} }{2y^{4} }

Step-by-step explanation:

Factor out 7 from top and bottom :

\frac{7(3x^6y^5)}{7(2x^2y^9)}

Divide top and bottom by 7 :

\frac{3x^6y^5}{2x^2y^9}

Simplify :  

\frac{x^6}{x^4}=x^{2}

Simplify :

\frac{y^5}{y^9} = y^{-4}  = \frac{1}{y^{4} }

Collect everything together :

\frac{3x^{4} }{2y^{4} }

Hope this helped and have a good day

A sealed tank of water measures 10cm x 8 cm x 40cm. When it stands on one
Pavel [41]

Answer:

New height = 6

Step-by-step explanation:

The water is going to be the same volume no matter how the tank is orientated.

So you can do this 2 ways.

First way

Find the volume in the tank when the water goes up 24 cm on the height.

V = L*W*h

L = 8

W = 10

H = 24

V = 1920 cm^3

Now do it using the

L = 40

W = 8

h = ?

1920 = L * W * h

1920 = 40 * 8 * h

1920 = 320 * h

h * 320 = 1920

h = 1920/320

h = 6

Or you can do it without finding the 1920

L*W*h = L1 * w1 * h1

8*10*24 = 40 * 8 * h                                The 8's cancel

10*24 = 40*h                                           Divide both sides by 10

24 = 4h                                                    Divide by 4

h = 6

Same as you got before.
