(b) What is 0.36 (six repeating) expressed as a fraction in simplest form?

zubka84 [21]

0.3666.....

If a number is repeating singly, just know it has to do with dividing by 9.

Let the number be x = 0.36.... (i)

Multiply both sides by 10.

10x = 3.66... (ii)

Equation (ii) - (i)

10x - x = 3.66 - 0.36

9x = 3.3

x = 3.3/9

x = (33/10)*(1/9)

x = 33/90

x = 11/30

The simplest fraction is 11/30

How do i solve this question, anyone help

Degger [83]

Answer:

a. $\sqrt{52}$ cm or 7.21cm

b. $\sqrt{170}$ cm or 13.04cm

c. x= $\sqrt{136}$ cm or 11.66cm, y= $\sqrt{191}$ cm or 13.82cm

Step-by-step explanation:

a. You have to find the length of the other two sides of the triangle using the information already given. The first side is 6cm and the other is 12-9=4cm. Because it's a right-angled triangle you can use pythagoras

$c^2=a^2+b^2\\x^2=6^2+4^2\\x^2=36+16\\x^2=52\\x=\sqrt{52}cm \\x=7.21cm$

b. You can use pythagoras again because it's a right-angle triangle

$x^{2} =7^2+11^2\\x^2=170\\x=\sqrt{170} cm\\ = 13.04cm$

c. In this question you have to find x and y. We need to find x first using pythagoras

$x^2=6^2+10^2\\x^2=136\\x=\sqrt{136}cm \\=11.66cm$

Now that we've found x we can find y using pythagoras but instead of find c, we will find another side

$c^2=a^2+b^2\\19^2=\sqrt{170} ^2 + b^2\\361=170+b^2\\361-170=170+b^2-170\\191=b^2\\b=\sqrt{191}cm \\=13.82cm$

Hope this helps :)

What is the equation of the graphed line in point-slope form?

Tomtit [17]

ANSWER

$y - 1 = \frac{2}{3} (x - 3)$

EXPLANATION

To find the equation in point-slope form, use the formula,

$y-y_1=m(x-x_1)$

The $m$
is the slope of the line.

We can read from the graph that, the straight line passes through, the points
$(-3,-3) \: and \: (3,1)$

We can use these two points to find the slope of the line.

The slope can found using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

This means that,

$m = \frac{1 - - 3}{3 - - 3}$

$m = \frac{1 + 3}{3 + 3}$

$m = \frac{4}{6}$

$m = \frac{2}{3}$

We now use one of the points, say
$(3,1)$
with the slope to find the equation of the line.

$y - 1 = \frac{2}{3} (x - 3)$
