Answer:

B.) 36/60

Step-by-step explanation:

some

equivalent fractions of 9/15:

3/5 = 6/10 = 9/15 = 12/20 = 15/25 = 18/30 = 21/35 = 24/40 = 27/45 = 30/50 = 33/55 = 36/60

Answer:

36/60

Step-by-step explanation:

<em>Either Cross Multiply or Turn into decimal to find the following answer.</em>

<em>For this question I suggest to turn into decimal.</em>

<em>Cross multiply would take longer time, but if you wish you could use both ways to check your answer.</em>

<em>I will be turn into decimal:</em>

<em>Main Fraction: 9/15 ⇒ 0.6</em>

<em>3/10 ⇒ 0.3</em>

<em>36/60 ⇒ 0.6</em>

<em>27/35 ⇒ 0.77142857142</em>

<em>20/30 ⇒ 0.66666666666</em>

<em>As you can see out of all the fractions:</em>

<em>36/60 is equal to 9/15</em>

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AC =16 and DC=5 what is the length of BC in the simplest ra
Nana76 [90]

The length of BC is 4 \sqrt{5}.

Solution:

Given ABC is a right triangle.

AC is the hypotenuse and BD is the altitude.

AB and BC are legs of the triangle ABC.

AC = 16 and DC = 5

<u>Leg rule of geometric mean theorem:</u>

$\frac{\text { hypotenuse }}{\text { leg }}=\frac{\text { leg }}{\text { part }}$

$\Rightarrow \frac{AC}{BC}=\frac{BC}{DC}$

$\Rightarrow \frac{16}{x}=\frac{x}{5}$

Do cross multiplication.

\Rightarrow  16\times 5 = x\times x

\Rightarrow  80= x^2

\Rightarrow  16\times 5= x^2

Taking square root on both sides.

\Rightarrow  \sqrt{16\times 5} = \sqrt{x^2}

\Rightarrow  \sqrt{4^2\times 5} = \sqrt{x^2}

square and square roots get canceled, we get

\Rightarrow  4\sqrt{ 5} = x

The length of BC is 4 \sqrt{5}.
