Answer:

Rational; irrational; irrational.

Step-by-step explanation:

a/3b is a rational number, as it is represented by a fraction and b ≠ 0.  This means the first blank is "rational."

√5 is an irrational number.  This means the second blank is "irrational."

Since we have an irrational number set equal to a rational number, this is a contradiction.  This means our original assumption is wrong, and the number is irrational.  This is the third blank.

There are Rational, irrational, and irrational are the correct options respectively.

A rational number is defined as a numerical representation of a part of a whole that represents a fraction number.

It can be a/b of two integers, a numerator a, and a non-zero denominator b.

Given Number = 3√5

We have to prove that 3√5 is an irrational number.  

Let us assume 3√5 is a rational number.

Because it is represented as a fraction and b ≠ 0, a/3b is a rational number. This implies that the first blank is "reasonable."

The number √5 is irrational. This indicates that the second blank is "irrational."

This is a contradiction since we have an irrational number set equal to a rational number. This signifies that our initial assumption was incorrect, and the number is irrational.

Therefore, the assumption is wrong, and the product is irrational.

The answer to the first part is $7 / each bracelet.

It'd be c) g(x)=(x-4)2+9

Answer : C

The function [tex]f(x)= x^2[/tex] has been translated 9 units up and 4 units to the right to form the function g(x)

For 9 units up, we add 9 at the end of f(x)

f(x) + 9

so equation becomes [tex]f(x)= x^2 + 9[/tex]

For 4 units right , we subtract 4 from x  in f(x)

f(x-4)

So the equation becomes [tex]f(x) = (x-4)^2 + 9[/tex]

Hence [tex]g(x) = (x-4)^2 + 9[/tex]

A counterexample for the following would be D, because it is the only positive number, which is opposite of a negative number.

The counter-example is 10. the correct option is D.

Absolute value refers to the removal of any preceding minus sign and the treatment of all numbers as positive (or zero).

Given that If |n| is a positive number, then n is a negative number.

Take all the negative values of n for the function.

|n| = |-10| = 10

|n| = |-4| = 4

|n| = |-1| = 1

|n| = |10| = 10

In the above values, the counter-example is 10 because the value is positive. After putting value in the absolute function the value will remain the same.

Therefore, the counter-example is 10. the correct option is D.

Answer:

number x = 3.

Step-by-step explanation:

Given : Three times the sum of a number and 4 is the same as 18 more than the number.

To find : what is the number.

Solution : We have given a statement

According to question :

Let the number= x

Sum of the number and 4 = x + 4

Three times the sum of the number and 4 = 3 ( x +4).

18 more than a number = 18 + x .

Three times the sum of a number and 4 is the same as 18 more than the number.

3 (x+4) = 18 + x

On distributing 3 over ( x+4)

3x + 12 = 18 + x

On subtracting both sides by 12

3x = 18 -12 +x

3x = 6+x

On On subtracting both sides by x

3x -x =6

2x = 6

On dividing both sides by 2

x = 3.

To verify plug x = 3 in 3x + 12 = 18 + x

3(3)+12 =18+3

9+12 = 18+ 3

21 =21

Therefore, number x = 3.

There are two good ways to go about this,

You can either do

Regular Price + .33 * Regular Price

or

Regular Price * 1.33

So, i'll do the latter.

18 * 1.33 = 23.94

So, the markup price is $23.94

Answer:

$23.94

Step-by-step explanation:

The slope is the change in Y over the change in X

Label each point (x1,y1) and (x2,y2)

Slope = y2 - y1 / x2-x1

Slope = -7 - (-11) / -6 - (-1)

Slope = -7 +11 / -6 +1

Slope = 4 / -5

Move the negative sign in front:

Slope = -4/5

Using the multiplication method, we find that 16 times 60 equals 960.

To find the product of 16 times 60, we can use the method of multiplication. The multiplication method is a straightforward way to find the product of two numbers by multiplying each digit separately and adding the results.

1. Write down the two numbers being multiplied: 16 and 60.

2. Start by multiplying the rightmost digit of the bottom number (60) with the top number (16). In this case, multiply 0 with 16, which equals 0.

3. Write down the result (0) below the line.

4. Now, multiply the next digit of the bottom number (6) with the top number (16). Multiply 6 with 16, which equals 96.

5. Write down the result (96) below the line, shifted one position to the left.

6. Finally, add the two results together: 0 + 96 = 96.

So, the product of 16 times 60 is 960.

Let the consecutive odd numbers be( x) and (x+2).

According to given condition.

(x)+(x+2) =284

solving  x+x+2 =284

2x+ 2 =284

subtracting 2 both sides

2x+ 2-2 =284-2

2x =282

dividing 2 both sides

x=141

as the second integer is (x+2) so

x+2 =141+2= 143

so integers are 141 and 143.

Factor 125[tex]x^{3}[/tex]-64

5³ₓ³ -  64

2.1      Factoring: 125[tex]x^{3}[/tex]-64

Theory : A difference of two perfect cubes [tex]a^3 - b^3[/tex] ,can be factored into

(a-b) • (a² +ab +b²)

Proof :  (a-b)•(a²+ab+b²) =

           [tex]a^3+a^2b+ab^2-ba^2-b^2a-b^3 =[/tex]

           [tex]a^3+(a^2b-ba^2)+(ab^2-b^2a)-b^3 =[/tex]

           [tex]a^3+0+0-b^3 =[/tex]

           [tex]a^3-b^3[/tex]

Check :  125  is the cube of  5

Check :  64  is the cube of   4

Check :  x³ is the cube of   x¹

Factorization is :

(5[tex]x[/tex] - 4)  •  (25[tex]x^{2}[/tex] + 20[tex]x[/tex] + 16)

2.2     Factoring  25[tex]x^{2}[/tex] + 20[tex]x[/tex] + 16

The first term is,  25[tex]x^{2}[/tex]  its coefficient is  25 .

The middle term is,  +20[tex]x[/tex]  its coefficient is  20 .

The last term, "the constant", is  +16

Step-1 :

Multiply the coefficient of the first term by the constant   25 • 16 = 400

Step-2 :

Find two factors of  400  whose sum equals the coefficient of the middle term, which is 20 .

                       -400     +     -1    =     -401

                     -200     +     -2    =     -202

                     -100      +     -4    =      -104

                      -80      +     -5    =      -85

                      -50      +     -8    =      -58

                      -40      +    -10   =      -50

The opposite of 4 is -4 for additivity and 1/4 for multiplicity.

In mathematical language, opposite of a number means inverse of a number and 2 inverses of the number are possible. One is additive inverse, while the other is multiplicative inverse.

To calculate an additive inverse of 4:

Let x be an additive inverse of 4, then

4+x=0

On transposing,

x=-4

Let y be multiplicative inverse of 4, then

4 x y=1

On transposing,

y=1/4

Thus, additive opposite of 4 is -4 and multiplicative opposite of 4 is 1/4.

x = 4 and x = - 9

In both cases the angles inside the parallel lines are same sided interior angles

24x - 1 + 20x + 5 = 180

44x = 176 ( divide both sides by 44 )

x = [tex]\frac{176}{44}[/tex] = 4

Similarly

x + 109 + x + 89 = 180

2x + 198 = 180 ( subtract 198 from both sides )

2x = - 18

Remember that dividing by a number is the same as multiplying by its reciprocal. To get a number's reciprocal, flip the numerator and denominator around.

In this case, 3/5's reciprocal is 5/3. With this information in mind, flip 3/5 to it's reciprocal, change the division sign to multiplication, then multiply as such:

[tex]\frac{7}{8} \times \frac{5}{3}=\frac{35}{24}[/tex]

Your final answer is 35/24.

Now firstly, we want to convert these mixed fractions into improper fractions. To convert them, multiply the whole number by the denominator then add the numerator and that's your new numerator. In this case:

[tex]2\frac{1}{10}=\frac{2*10+1}{10}=\frac{21}{10}\\\\1\frac{1}{5}=\frac{1*5+1}{5}=\frac{6}{5}\\\\\frac{21}{10}\div \frac{6}{5}[/tex]

Next, we want to convert this expression to multiplication. Similar to before, convert 6/5 to its reciprocal, change the multiplication sign to division, and multiply as such:

[tex]\frac{21}{10}\times \frac{5}{6}=\frac{105}{60}[/tex]

Now you may think that 105/60 is the right answer, however we can simplify it further. The numerator and the denominator have a GCF, or greatest common factor, of 15. With this, divide the fraction by 15/15 as such:

[tex]\frac{105}{60}\div \frac{15}{15}=\frac{7}{4}[/tex]

Your final answer is 7/4.
