To solve this problem, we are going to use the percent proportion, a/b = p/100, where a is the part of a number b, the whole, and p is the percentage out of 100.
When we fill in our known integers into this equation, we get
21.12 / b = 25.6 / 100
Next, to simplify this equation, we should use cross products (means - extremes products theorem). This means multiplying the numerator of one fraction and the denominator of the other fraction and setting them equal to one another.
21.12(100)=25.6(b)
When we multiply, you get
2112 = 25.6b
Finally, we divide both sides by 25.6, to get our variable b, alone, and without a coefficient.
82.5 = b
Therefore, 25.6% of the number 82.5 is 21.12.
270 I think but I’m not 100% sure
Answer:
All real numbers
Step-by-step explanation:
To find the range of the function 
draw the graph of ths function (see attached diagram for details).
Since the base of the logarithm is 
the graph is increasing and passes through the point (1,0).
The domain of this function is
The range of this function is
or all real numbers.
Answer:
Non Linear
Step-by-step explanation:
Its non-linear because when you put X to the second power, it will change the function into a quadratic function
Answer:
1/10.
Step-by-step explanation:
Total allowance=1
Half to wife so 1-1/2=1/2(Left from total)
1/5 to each son so 2/5 to both(Total for sons).
Left for daughter 1/2-2/5=1/10(Ans)
