There are four units of temperatures: Celsius, Fahrenheit, Kelvin and Rankine. The units of Kelvin and Rankine are the absolute temperatures that are very useful in calculations involving process systems.
However, for room temperatures, the common units used are Celsius and Fahrenheit. There is a derived equation relating Celsius and Fahrenheit. But for practical purposes where you don't have to memorize the equation, just remember that the boiling point of water is 100°C or 212°F. So, we use this relationship through ratio and proportion:
100°C/212°F = 158°C/x
x = (158*212)/100
x = 334.96°F
Answer:
Step-by-step explanation:
Area of a rectangle = Lenght x width
Lenght = 80 cm
Width = 60 cm
Height = 50 cm
A = 80x 60 = 4800 cm^2
The solution of this equation is x = 5 and x = 9.
<h3>What is the solution?</h3>
Let us recall that what we have here is a radical equation as follows;
√7x+1 - √x-5 = 6
When we isolate we have';
√7x+1 = √x-5+6
Taking the square of both sides;
(√7x+1)^2 = (√x-5+6)^2
Hence;
7x+1 = x-5+36+12√x-5
-12√x-5 = -7x-1+x-5+36
12√x-5 = 6x-30
Raising this equation to power 2
144x-720 = 36x^2-360x+900
When we rearrange we obtain;
36x2 - 504x + 1620 = 0
Hence;
x = 5 and x = 9
