use the formula C equals 5 / 9 f - 32 wherever represents degrees Fahrenheit and C represents degrees in celsius to convert 77 d

Drupady [299]

Answer:

Value of 77 degree Fahrenheit is 25 degree Celsius.

Step-by-step explanation:

Given:

Fahrenheit = 77 (degree).

To convert in Celsius .

Formula of conversion to be used = $(C) =\frac{5}{9}(F - 32)$

Plugging the values of $F=77$ in the above equation.

We have,

⇒ $(C)=\frac{5}{9}(F -32)$

⇒ $(C)=\frac{5}{9}(77 -32)$

⇒ $(C)=\frac{5}{9}*(45)$

⇒ $(C)=\frac{5*45}{9}$

⇒ $(C)=\frac{225}{9}$

⇒ $(C)=25$ (degrees)

So the value of 77 degrees in Fahrenheit scale is equivalent to 25 degrees in Celsius scale.

Answer:

<h2>see the answers ⤵️</h2>

Step-by-step explanation:

<h3>to understand the solving steps</h3><h3>you need to know about</h3>

$\sqrt{ \frac{x}{y} } < = > \frac{ \sqrt{x} }{ \sqrt{y} } \\ and \: \\ \sqrt{x} \times \sqrt{y} = \sqrt{xy}$
PEMDAS

let's solve:

$a) \sqrt{ \frac{9}{25} }$

$\frac{ \sqrt{9} }{ \sqrt{25} }$

$\frac{3}{5}$

$b) \frac{ \sqrt{12} }{ \sqrt{3} }$

$\frac{ \sqrt{12} }{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} }$

$\frac{ \sqrt{12 \times 3} }{ (\sqrt{3} )^{2} }$

$\frac{ \sqrt{36} }{3}$

$\frac{6}{3}$

$2$

$c) \frac{ \sqrt{15} }{ \sqrt{3} }$

$\sqrt{5}$
