Answer:

\frac{17}{495} will be the fraction.

Step-by-step explanation:

Here the recurring decimal number is 0.0343434....

To convert this recurring decimal to fraction we assume,

x = 0.03434....   -------(1)

Now multiply both the sides with 100.

100x = 3.43434.... ------(2)

Now subtract equation (1) from equation (2).

100x = 3.43434

<u>      x = 0.03434</u>

99x = 3.4

x = \frac{3.4}{99}

  = \frac{34}{990}

x = \frac{17}{495}

Therefore, fraction that represents the decimal number is \frac{17}{495}

Line K has the equation 9x-4y=-5x4.
Yuki888 [10]

Answer:

y = (9/4)x + 2, given that I've assume the correct meaning of "-5x4."

Step-by-step explanation:

A parallel line has the same slope as the reference line,

The reference line is 9x-4y = -5x4, as written.  I'm not sure the 4 belongs, but I'll assume it is written correctly.  I'm not sure if the term -5x4 is meant to mean -5x^4, -20x or -20.  I'll assume -20:

9x-4y = -20

Put the equation into standard slope-intercept form:  Y = mx + b, where m is the slope and b is the y-intercept (the value of y when  x = 0).

-4y = -9x - 20

y = (9/4)x + 5

This line has a slope of (9/4).  The parallel line will have the same slope.

y = (9/4)x + b

We can find a value of b that would shift this line to include (4,7) by using this point in the equation:

y = (9/4)x + b

7 = (9/4)(4) + b

7  = 9 + b

b = 2

The equation of a line parallel to the reference line is y = (9/4)x + 2

Find the area of the trapezoid!!!! PLEASE HELP!!!!
san4es73 [151]

ANSWER

32 \sqrt{3}  {ft}^{2}

EXPLANATION

The area of a tra-pezoid is half times sum of the bases times the vertical height.

From the diagram ( see attachment) we use the Pythagoras Theorem to obtain,

{x}^{2}  +  {(4 \sqrt{3}) }^{2}  =  {8}^{2}

{x}^{2}  +  48  =  64

{x}^{2}  =  64 - 48

{x}^{2}=16

x =  \sqrt{16}  = 4ft

This implies that , y=10-4=6ft

The area of tra-pezoid

=  \frac{1}{2} (10 + 6) \times 4 \sqrt{3}

=  \frac{1}{2} (16) \times 4 \sqrt{3}

=  8\times 4 \sqrt{3}

= 32 \sqrt{3}  {ft}^{2}
