Answer:
The temperature in degrees Celsius is <em>-48°C </em>.
Step-by-step explanation:
The given equation is:
v = 20√[t + 273]
Therefore, rearranging we get:
(v / 20)² = t + 273
t = (v / 20)² - 273
but the speed of sound, v, is equal to 300 m/s
Therefore,
t = (300 / 20)² - 273
<em>t = -48°C</em>
<em></em>
Therefore, the temperature in degrees Celsius is <em>-48°C </em>.

Answer:
The cost of desktop before finance charge was $1750.
The cost of laptop before finance charge was $1900.
Step-by-step explanation:
Let us assume this is a simple interest scenario.
Let D be the cost of desktop
Let L be the cost of laptop
Given- the laptop cost $150 more than the desktop.
So,
The total finance charge for 1 year is given by :

Substituting the value of L here, we get;

=>
=> 
=> 
=> 
D = $1750
As
So, 
L = $1900
We can check this :

=> 
=> 
So, the cost of desktop before finance charge was $1750.
The cost of laptop before finance charge was $1900.
