can someone tell me which answer in order is correct

Answer:

The options as included in the attachment section are:

A. real numbers B.Cardinality C.element D.Set

The answer is D. Set

Step-by-step explanation:

In mathematics, a set is a group of well-defined objects that share common characteristics as rightly stated in this question. So in a mathematical calculation, the elements or objects collected as a group is called SET. The types of set include empty set, finite set, infinite set, universal set etc.

- Since set represents the whole collection or group, each object, which can be number, letter etc. in the group is an ELEMENT. Likewise, the cardinality of a set refers to the number of elements contained in a particular set.

c 60.5 ft x 2ft

Step-by-step explanation:

60.5 ft x 2 = 121 ft

The required possible side length of the tablecloth is 11ft x 11ft.

Given that,
Mrs. Sullivan wants to make a square tablecloth for her dining room table. She has 121 ft? of fabric. What are the possible side lengths of the tablecloth to be determined.

A square is for sided regular polygon, where the length of all sides is identical and the angle between the adjacent side is 90°.

Here,
She has 121 ft² of fabric.
She wants to make a square tablecloth for her dining room table.\

Area of the square = a²
121 = a²
a = √121
a = 11 ft

Thus, the required possible side length of the tablecloth is 11ft x 11ft.

Answer:

see below

Step-by-step explanation:

Let f = number of friends

all but one friend got 6 pieces   and 1 friend got 2  for a total of 50 pieces

6(f-1) + 2 = 50

Subtract 2 from each side

6(f-1) +2-2 = 50-2

6(f-1) = 48

Divide by 6

6(f-1)/6 = 48/6

f-1 = 8

Add 1 to each side

f-1+1=8+1

f=9

Answer:

x = -1.52016

Step-by-step explanation:

Step 1: Write equation

3(2x - 7) = 5(x + 3) + 2x⁷

Step 2: Solve for x

Given:

JK is formed by J(-12, 3) and K(8,-5).

Line r is the perpendicular bisector of JK.

To find:

The equation of line r is slope intercept form.

Solution:

Line r is the perpendicular bisector of JK. So, it passes through the midpoint of J and K.

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-12+8}{2},\dfrac{3+(-5)}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-4}{2},\dfrac{-2}{2}\right)[/tex]

[tex]Midpoint=\left(-2,-1\right)[/tex]

Slope of JK is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{-5-3}{8-(-12)}[/tex]

[tex]m=\dfrac{-8}{20}[/tex]

[tex]m=\dfrac{-2}{5}[/tex]

Product of slopes of two perpendicular lines is -1.

[tex]m_1\times m_2=-1[/tex]

[tex]-\dfrac{2}{5}\times m_2=-1[/tex]

[tex]m_2=\dfrac{5}{2}[/tex]

The slope of perpendicular line r is [tex]\dfrac{5}{2}[/tex] and it passes through (-2,-1). So, the equation of perpendicular line is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-(-1)=\dfrac{5}{2}(x-(-2))[/tex]

[tex]y+1=\dfrac{5}{2}(x+2)[/tex]

[tex]y+1=\dfrac{5}{2}x+5[/tex]

[tex]y=\dfrac{5}{2}x+5-1[/tex]

[tex]y=\dfrac{5}{2}x+4[/tex]

Therefore, the equation of line r is [tex]y=\dfrac{5}{2}x+4[/tex].

The required equation of line "r" in slope-intercept form is y = 5/2x + 15

First, we need to find the equation of a line in slope-intercept form as

y = mx + b

m is the slope of the line

b is the y-intercept

Given the coordinate points  J(-12, 3) and K(8,-5)

Get the slope of the line

Slope  = -5-3/8+12

Slope = -8/20

Slope - -2/5

Slope of the line "r" perpendicular is 5/2

Get the y-intercept of line r

Substitute (8, -5) and m = 5/2 into y = mx + b

-5 = -5/2(8) + b

-5 = -20 + b

b = 15

Hence the required equation of line "r" in slope-intercept form is y = 5/2x + 15

Step-by-step explanation:

(6[tex]x^{5}[/tex]z)^3

6^3 is 226

*(x^2)^3=  x^6        (5*3= 15)

*when there are exponents being raised to a power, the exponents are multiplied

**(z^1)^3= z^3     (3*1= 3)

** all numbers are raised to the 1st power (unless otherwise noted x^2, 5^4 2^2, etc)

So the top would end up being 226x^6z^3

Now, since this number is over 4x^4z^2,  you need to divide 226x^15z^3 by 4x^4z^2

**divide like terms**

226/4= 54

***x^15/ x^4= x^x^11

*** when you divide exponents, you subtract the bottom number from the top, in this case:

15-4

that equalls 11

So x^11

you do the same for z:

z^3/z^2= z^1 or z      (3-2=1 )

You put it all together and you end up with

54x^11z

Answer:

7

Step-by-step explanation:

An "additive inverse" refers to a number that when added to a specific number equals to "zero."

In the question above, the additive inverse of -7 is 7 because: -7 + 7 = 0

Other examples:

1. The additive inverse of 2 is -2 because: 2 + (-2) = 0

2. The additive inverse of -100 is 100 because: -100 + 100 = 0

3. The additive inverse of [tex]\frac{1}{2}[/tex] is -[tex]\frac{1}{2}[/tex] because: [tex]\frac{1}{2}[/tex] + -[tex]\frac{1}{2}[/tex] = 0

The additive inverse of -7 is equal to 7.

The additive inverse of a number is the number that, when added to the original number, gives a sum of zero.

To determine the additive inverse of -7, we need to find the number that, when added to -7, results in zero.

To do this, we can multiply -7 by -1, which is the multiplicative inverse of 1. Multiplying a number by its multiplicative inverse always gives the additive inverse of that number.

So, -7 multiplied by -1 is:

-7 x -1 = 7

Therefore, the additive inverse of -7 is 7.
