2 25 divided by 11 10 in fraction
koban [17]

Answer:

\frac{4}{55}

Step-by-step explanation:

\frac{2}{25}  \div  \frac{11}{10}

\frac{2}{25}  \times  \frac{10}{11}

\frac{2}{5}  \times  \frac{2}{11}  =  \frac{2 \times 2}{5 \times 11}

\frac{4}{5 \times 11}

=  \frac{4}{55}

I need help with this question. Can you please help me. I’ll give you 18 points if it’s correct
lukranit [14]

Answer:

34.4

Step-by-step explanation:

Using Triangle Sum Theory, you see that the triangles are similar. They have the same angle measurements. That means their corresponding sides are proportional.

\frac{MN}{NO} = \frac{PQ}{QR}

\frac{14}{11} = \frac{PQ}{27}

Cross multiply

14(27) = 11(PQ)

378 = 11(PQ)

\frac{378}{11} = PQ

PQ = 34.4

Please answer! this is an important exam that im taking right now.

Answer:

Required ordered pair is (0,0) for system of equation

Step-by-step explanation:

The given system of equation is

A). 9^{12x} = 9^{3y}

B). y^{4} - 9y^{2} x^{2} =16y

On simplifying the equation A

9^{12x} = 9^{3y}

Take log on both side,

(12x) (log9) = (3y) (log9)

4x=y

To find the solution of the system of the equation :

Replacing value of y=4x in equation B,

y^{4} - 9y^{2} x^{2} =16y

(4x)^{4} - 9(4x)^{2} x^{2} =16(4x)

256x^{4} - 144x^{2} x^{2} =64x

256x^{4} - 144x^{4}=64x

112x^{4}=64x

We get,

x=0 and x=0.829

Since, 0.829 is not integer number

Only solution of equations is x=0

For the value of y

Replace value x in y=4x=0

Thus, Required ordered pair is (0,0)
