How do you write 0.045 as a reduced fraction
Anvisha [2.4K]
0.045 = 45/1000

Divide top and bottom by their greatest common factor.
It looks to me as though the greatest common factor of  45  and  1,000  is  5 .
Divide top and bottom by  5  and we have  <u>9/200</u> .  That's the simplest form.

Combine the radicals. 3√5-8√5+2√5
weeeeeb [17]

Answer:  -3\sqrt{5}

-3 times the square root of 5

=============================================

Explanation:

Let x = \sqrt{5}

Replace all the root 5 terms with x and we go from

3\sqrt{5}-8\sqrt{5}+2\sqrt{5}

to

3x-8x+2x

From here, combine like terms to get

3x-8x+2x = -5x+2x = -3x

and the last thing to do is replace the x with sqrt(5)

-3x = -3\sqrt{5}

Meaning that,

3x-8x+2x = -3x

3\sqrt{5}-8\sqrt{5}+2\sqrt{5} = -3\sqrt{5}

The value of x will be equal to x = 79.

<h3>What is the triangle?</h3>

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

For an isosceles triangle, the value of two opposite angles is equal and the opposite sides are also equal.

The Sum of the three angles is equal to 180 degrees so the third angle will be calculated as:-

Angle = 180 - 142 - 19 = 19

Now applying Lami's theorem in the triangle we will get the third side.

\dfrac{sin\angle A}{a} = \dfrac{sin\angle B}{b} = \dfrac{sin\angle C}{c}

\dfrac{Sin 19}{42}= \dfrac{Sin142}{x}

x = \dfrac{42\times Sin 142}{Sin19}

x = 79

Therefore the value of x will be equal to x = 79.
