Answer:
Using coal, steam, and <u>OXYGEN,</u> the fischer-tropsch procedure converts coal into a liquid fuel.
Step-by-step explanation:
A series of chemical reactions in which hydrogen and carbon monoxide converges into liquid hydrocarbons by using a metal catalyst. This process is called The Fischer-Tropsch process.
Converting Coal into Liquid Fuel is know as Coal liquification.
IN Liquification process Oxygen, heat is used.
Therefore steam is for heat and oxygen to covert coal into liquid fuel.
Given:
The scale factor between two circles is 
.
To find:
The ratio of their areas.
Solution:
We know that, all circles are similar.
The ratio of the areas of similar figures is equal to the ratio of squares of their corresponding sides or equal to the square of ratio of their corresponding sides.
The scale factor is the ratio of the corresponding sides.
Ratio of areas of circles = Square of scale factor between two circles
Therefore, the correct option is D.
Answer:
The missing value is(0,0)
Step-by-step explanation:
The complete question is:
2x+3y=5x-y
Complete the missing value in the solution to the equation.
( ,0)
<u>Solution:</u>
We have given:
2x + 3y = 5x - y
Combine the like terms:
2x-5x= -y-3y
-3x = -4y
Both negative signs will be cancelled out by each other.
So we have,
3x = 4y
We have given y = 0
Then
3x = 4*0
3x= 0
Divide both sides by 3
3x/3 = 0/3
x = 0
y=0
Therefore missing value is(0,0)
