Answer: 1/3 x 1/3 = 1/9
Step-by-step explanation: have a nice day
Answer:
The correct answer is "50%".
Step-by-step explanation:
The given values are:
Gravel,
= 
Water,
= 
Cement,
= 1
Sand,
= 2
Now,
The total mixture will be:
= 
By substituting the values, we get
= 
= 
= 
hence,
The percentage of sand will be:
= 
= 
=
%
3x+4y=12
4y=12-3x
y=(12-3x)/4 <---------- This is f(x)
---------------------
3x+4y=12
3x=12-4y
x=(12-4y)/3
Therefore:
f⁻¹(x)=(12-4x)/3
=[4(3-x)]/3
Answer:
N=4
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
