You want to convert 50°F to degrees Celsius. Solve the formula for C, and then use it to convert the temperature. What is the co
Zepler [3.9K]

Answer:

  • C = (5/9)(F -32)
  • 50°F ⇒ 10°C

Step-by-step explanation:

Starting with the formula for degrees Fahrenheit, we can solve for degrees Celsius.

  F = 32 +9/5C

  F -32 = (9/5)C . . . . . subtract 32

  (5/9)(F -32) = C . . . . multiply by the inverse of the coefficient of C

The formula for Celsius temperature from Fahrenheit temperature is ...

  C = (5/9)(F -32)

__

For F = 50, the corresponding Celsius temperature is ...

  C = (5/9)(50 -32) = (5/9)(18) = 10 . . . degrees Celsius

Find the third side in simplest radical form:<br> 25
Gre4nikov [31]

Answer:

<h3>\boxed{  \bold{24}}</h3>

Step-by-step explanation:

\mathsf{given}

\mathsf{hypotenuse(h) = 25}

\sf{perpendicular (p) = 7}

\sf{base(b) = }?

Now, Using Pythagoras theorem

\sf{{h}^{2}  =  {p}^{2}  +  {b}^{2} }

plug the values

⇒\sf{  {25}^{2}  =  {7}^{2}  +  {b}^{2} }

Evaluate the power

⇒\sf{625 = 49 +  {b}^{2} }

Swap the sides of the equation

⇒\sf{49 +  {b}^{2}  = 625}

Move constant to right hand side and change it's sign

⇒\sf{ {b}^{2}  = 625 - 49}

Calculate the difference

⇒\sf{ {b}^{2}  = 576}

Squaring on both sides

⇒\sf{b = 24}

Hope I helped!

Best regards!
