Answer with explanation:

Rational numbers are those numbers which can be written in the form of $\frac{a}{b}$ , where , b≠0.

Rational number can be written in the following way:

Integers + Terminating Decimal + Non terminating Repeating Decimal

When you will look at , fraction $\frac{1}{5}$ , it is terminating Decimal.

So, apart from any irrational number which is non terminating non repeating , if you multiply $\frac{1}{5}$ , with any number on the number line , that is any rational number ,because product of two rational is always a rational ,you will get a rational number.

What is 0.5 divided by 12.5

lisabon 2012 [21]

Answer:

0.04 or 4%

Step-by-step explanation:

-A fraction consists of two numbers and a fraction bar: 0.5/12.5

- The number above the bar is the numerator: 0.5

The number below the bar is the denominator: 12.5

-Divide the numerator by the denominator to get fraction's value: Val = 0.5 ÷ 12.5

Calculate fraction's value.

Divide the numerator by the denominator to get fraction's value: 

0.5 ÷ 12.5 

= 0.04

<h3> Calculate the percent value:</h3>

Note:100/100 = 100 ÷ 100 = 100% = 1Multiply a number by the fraction 100/100,... and its value doesn't change.0.04 =

= 0.04 × 100/100 

= (0.04 × 100)/100 

= 4/100 

= 4%;

<h3>In other words:</h3>

1) Calculate fraction's value.

2) Multiply that number by 100.

3) Add the percent sign % to it.

Answer:

0.5÷12.5 = 4%

Which picture shows the inverse, f −1, of the function shown?

LekaFEV [45]

Answer:

(d) Inverse of f. Domain: 6, 9, 3. Range: 8, 10, 12. 6 goes to 8; 9 goes to 10; 3 goes to 12.

Step-by-step explanation:

Apparently function f is defined by the ordered pairs (8, 6), (10, 9), (12, 3).

The inverse function will be defined by the ordered pairs with the input and output reversed:

(6, 8), (10, 9), (3, 12)

This seems to be described by the last answer choice.

Please anyone help me answer this question am giving the brainliest

DochEvi [55]

Answer:

(-3/2x+1) + (3/x-1)

Step-by-step explanation:

Dont put the answer in parenthesis, I just did that to seprate it so it was easier to read. If you need it to be put in word form for it to be easier for you to understand, its "negative three divided by two x plus one, plus 3 divided by x minus 1"

First, rewrite the expression as 3x+6/2x^2+x-2x-1

Then, factor the expression, 3x+6/x*(2x+1)-(2x+1) (*=multiply)

Then, write a new fraction for each factor in the denominator, then write a new fraction, 3x+6/(2x+1)*(x-1) to (A)/2x+1 + B/x-1)

Then write terms in the numerators, for now we will use A and B.

Now we set the sum of the fractions equal to the original fraction.

3x+6/(2x+1)*(x-1) = A)/2x+1 + B/x-1).

Then reorder and group the terms, giving you 3x+6=(A+2B)x+(-A+B).

Now equate the coefficiants, {6= -A+B, 3= A+2B

Then substitute back, (A, B)=(-3, 3)

Now finally, just rewrite the fraction. (-3/2x+1) + (3/x-1)

Hope this helps! Sorry its kind of long.
