Answer:

angle b is 62 degrees. This is because if we solve for x, by putting the 2 equations equal to each other(because they are vertical angles), than we figure out that x=6. Now plug that into angle b's equation, and you get 62 degrees.

What is the answer for. What is hg = 45g
goldenfox [79]
To solve hg = 45g

Apply Multiplication Property of Equality which is to multiply both sides of the equation with 1/g.
  
  hg (1/g) = 45g (1/g)
               h = 45

Or you can divide both sides with the equation with g.
      
   hg / g = 45g / g

You can cancel g to both sides.
Then, 
               h = 45

According to​ Charles's law, if the pressure is held​ constant, the volume of a gas varies directly with the temperature measure
Ksju [112]

Answer:

V₂ = 252 cm³

Step-by-step explanation:

Charles's law = If the pressure is held​ constant, the volume of a gas varies directly with the temperature measured on the Kelvin scale.

Mathematically, V=kT

\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}

We have, V₁ = 192 cm³, T₁ = 112 K, T₂ = 147 cm³, V₂ = ?

Using the above relation of Charles's law :

V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{192\times 147}{112}\\\\V_2=252\ cm^3

So, the new temperature is 252 cm³.
