Answer:
The probability of the dart hitting the inner circle is 11.2 %.
Step-by-step explanation:
To solve this problem we first need to find the area of the whole target and the area of the smaller target. Since they're both circular, their area is given by the formula:
area = pi*r²
For the whole target:
area target = pi*(6/2)² = 28.26 ft²
For the inner target:
area inner = pi*(2/2)² = 3.14 ft²
The probability that the dart will hit the inner area is:
p = area inner / area target = 3.14 / 28.26 = 0.112
The probability of the dart hitting the inner circle is 11.2 %.

Step-by-step explanation:
Answer:
y = 9 + 4x/3
x = -27/4 + 3y/4
*everything that looks like x/y is a fraction, -27/4 is entirely negative
This means Square root (^1/2). this is kind of hard to read. anyways. 32^(1/2) separates into 4^(1/2) and 8^(1/2), which further separates into 4^(1/2) and 2^(1/2), root 4 becomes 2, their are two root 4's, so you get 2 x 2, and you are left with 2^(1/2) now why go to all this trouble. because now you can multiply the 4 you created (2x2) times, the 7... giving you 28*2^(1/2) now subtract it from the the other one with root 2. -5*2^(1/2), giving you 23*2^(1/2)-...idk what that last bit is. if its a odd number then this is the end of the problem, if you can get it to root 2. then do that and simplify.
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.
