what is 640 divided by 20

Step-by-step explanation:

Qualitative data are discrete, for instance, "Yes/No" type questions. They are usually presented in bar charts or pie charts to show the portion of different populations with certain characteristics in a single experiement (e.g. Not allergic to ginger VS allergic to ginger).

Qualitative data are usually continuous, and can show a trend or distribution numerically. They are usually presented by, for instance, line charts (e.g. Distribution of resident age in block E)

Answer:

x = 12

Step-by-step explanation:

2(x-4)=16

2 times x +2 times -4 = 16

2x -8 =16

2x -8 (+8) =16 (+8)

2x = 24

2x (divided by 2) = 24 (divided by 2)

x = 12

Answer:

Wouldn't be 100% since all the numbers on a standard number cube are less than 7?

Step-by-step explanation:

Answer:

First, set x equal to .93

x=.939393939393...

Then, since the repeating is by two digits, let's multiply x by 100

This would make 100x=93.9393939393...

Now, we can subtract 100x−x

This would leave us with 99x=93 because the repeating digits cancel out.

This looks much easier now right?

Just divide the 99 and isolate the x to get x=9399

Get the simplified fraction, and the final answer is x=3133

Answer:

2[tex]\sqrt{} 15[/tex] (decimal 7.74596)

Step-by-step explanation:

That sign is called a radical sign used to find square roots so it is used to extract or find the index of the number in this case the answer to that question

So you have

√6 √5 √2 first you find the value of the first number my finding the square root

(by changing the number into a decimal and using long division is the method i use)

Since √6 is √3 and √2 then you put them together like so

√2 √3 √5 √2

then you apply radical rule

(which the formula is √a √a = a,   a>0)

in this case it is √2 √2 = 2

and that equals

2 √3 √5

Apply radical rule again

(now that we did the formula the first time the formula changes now it is √a √b = √ab,    a>0, b>0)

now it is

2√3 x 5

now you just multiply 3 and 5and get 15

then you get

2[tex]\sqrt{} 15[/tex] (decimal 7.74596)

Answer:

If your shape is a regular polygon (such as a square in the example above) then it is only necessary to measure one side as, by definition, the other sides of a regular polygon are the same length. It is common to use tick marks to show that all sides are an equal length.

Answer:

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.

Step-by-step explanation:

perimeter of square = 30cm

perimeter of rectangle = 30cm

area of square is = 30×30= 900 cm

Answer:

undefined

Step-by-step explanation:

slope = ((y2-y1)/2) / ((x2 - x1 )/2)

since x1 = x2

so x2 - x1 = 0

then ((y2-y1)/2) / 0 = undefined

Answer:

|0| = 0

Step-by-step explanation:

Absolute value of a number is its value sans its sign, positive or negative i.e. for +17, it is 17 and for −17 to it is 17.

Number 0 does not have any sign and +0=−0=0. Hence, we can say that |0|=0

An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:

Constant: A constant is a fixed numerical value.

Variable: A variable is a symbol that doesn't have a fixed value.

Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.

Coefficient: A coefficient is a number that is multiplied by a variable in an expression.

Given:

A^B(B +2)

As, both are in ratio of multiplication and B is also the power for A.

There is no possible of decreasing the quantity.

Hence, if A is constant then B increasing and B is constant then A is increasing .

Answer:

41 x 18 = 738 + 14 = 752

Step-by-step explanation:

Its says that there 42 rows .First row has 14 seats and the rest of 41 rows has with + 4 more so every row has 18 seats ,and asks how many seats are in total in the theater . To show that you understood the question you have to multiply 41x18 which gives 738 and then add + 14 from the first row so you can find out how many seats are in total .Hope that helps .

The rules of a dataset are what guide the formation of the dataset. The rule that describes how to find the number of legs for any  number of insects.

Let:

[tex]x \to[/tex] number of insects

[tex]y \to[/tex] number of legs

From the table (see attachment), we notice the following:

As the number of insects increases by 1, the number of legs increases by 6.

Hence, the rule that describes how to find the number of legs is "Add 6"

A better approach is as follows:

From the table we have:

[tex](x_1,y_1) = (1,6)[/tex]

[tex](x_2,y_2) = (2,12)[/tex]

Calculate the slope (m) of these points

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

[tex]m = \frac{12 - 6}{2-1}[/tex]

[tex]m = \frac{6}{1}[/tex]

[tex]m = 6[/tex]

The equation is then calculated as:

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

This gives:

[tex]y = 6(x - 1) + 6[/tex]

[tex]y = 6x - 6 + 6[/tex]

[tex]y = 6x[/tex]

Hence, the rule is:

Any of the above, can be stated as the rule that how to find the number of legs for any  number of insects.

Answer:

Step-by-step explanation:

Let Numerator be : x

Denominator be : x + 7

Now,

Numerator = x + 6

Denominator = ( x + 7) - 5

According to the question,

[tex] \displaystyle \: \sf \dashrightarrow \: \frac{x + 6}{(x + 7) \: - 5} = \: \frac{3}{2} [/tex]

[tex]\displaystyle \: \sf \dashrightarrow \: 2(x + 6) \: = 3 \{ \: (x + 7 ) - 5\} \: [/tex]
