Answer:

65%

Step-by-step explanation:

We're looking for how big a part of the original price the reduced price is.

This can be done using division.

E.g., if the reduced price was $1, and the original price was $10, we can find how big of a part $1 is of $10 by dividing them.

[tex]\frac{1}{10} = 0.1 = 10\%[/tex]

The reduced price is 10% of the original price. Remember that 0.1 in decimal is 10%, same as how 1.0 is 100%, and 0.3 is 30%.

Let's try this using our dresses. The reduced price was $39, and the original price was $60.

[tex]\frac{39}{60} = 0.65 = 65\%[/tex]

The dresses were sold at 65% of the original price.

Note, this does NOT mean that they were sold at a 65% discount. To find that, we'd have to find out how big the discount was. Then, we'd divide it by the original price.

For example, if the original price was $10, and the reduced price is $9, then the reduced price is 90% of the original price, but it's at a 10% discount.

[tex]\frac{9}{10} = 0.9 = 90\%[/tex]

[tex]10-9=1[/tex]

[tex]\frac{1}{10}=0.1=10\%[/tex]

Answer:

2

Step-by-step explanation:

The scale factor can be determined by simplifying the ratio of the corresponding length of the preimage to that of the image.

The preimage is the smaller shape shown, while the image is the lager shape shown.

Any side length can be used.

Thus, length of one side of the preimage, AD = 4 - 1 = 3 units

AD corresponds to side length A'D' if the image = 7 - 1 = 6 units

The ratio of the image length to the ratio of the preimage length = the scale factor

Thus:

6 : 3 = [tex] \frac{6}{3} = 2 [/tex].

The scale factor is 2.

Answer:

Nikki is 16, Travis is 8

Step-by-step explanation:

We need to set up an equation

If x is Nikki's age, then Travis' would x-8 since Nikki is 8 years older.

x+(x-8)=24

2x-8=24

2x=32

x=16

Nikki is 16, Travis is 8

Answer:

the oldest is 16 and the other sibling Travis =8

Step-by-step explanation:

x+y=24

x-y=8  ⇒ x=8+y

solve by substitute

8+y+y=24

2y=24-8

2y=16

y=16/2=8

x=8+y

x=8+8=16

x=16

y=8

Answer:

  3×1/10 +5×1/100 +6×1/1000

Step-by-step explanation:

You have not shown Armando's work, but we know there are several ways that expanded form can be written:

  0.356 = 0.3 + 0.05 + 0.006

  = 3×0.1 + 5×0.01 + 6×0.001

  = 3×10^-1 + 5×10^-2 + 6×10^-3

When the place values are expressed as fractions, this is ...

  = 3×1/10 + 5×1/100 + 6×1/1000

Answer & Step-by-step explanation:

definition of coordinate pair

A system and method is provided for converting an input signal from a sequence of rectangular coordinate pairs to a sequence of polar coordinate pairs.

solving by graphing

A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system

solving by substitution

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other.

solving by elimination

The elimination method of solving systems of equations is also called the addition method. To solve a system of equations by elimination we transform the system such that one variable "cancels out". ... In order to solve for y, take the value for x and substitute it back into either one of the original equations.

slope-intercept form

the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept

standard form

Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.

Small numbers can also be written in standard form. However, instead of the index being positive (in the above example, the index was 3), it will be negative. The rules when writing a number in standard form is that first you write down a number between 1 and 10, then you write × 10(to the power of a number)

term

In Algebra a term is either a single number or variable, or numbers and variables multiplied together.

Terms are separated by + or − signs, or sometimes by divide.

constant

A fixed value.

In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number.

variables

A symbol for a value we don't know yet. It is usually a letter like x or y.

Example: in x + 2 = 6, x is the variable.

Why "variable" when it may have just one value? In the case of x + 2 = 6 we can solve it to find that x = 4. But in something like y = x + 2 (a linear equation) x can have many values. In general it is much easier to always call it a variable even though in some cases it is a single value.

multiplicative combination

Any of the ways we can combine things, when the order does not matter.

Example: For a fruit salad, how many different combinations of 2 ingredients can you make with apple, banana and cherry?

Answer: {apple, banana}, {apple, cherry} or {banana, cherry}

When the order does matter, such as a secret code, it is a Permutation.

Answer:

0.4 represents the height of the base.

0.6 represents the height of each block.

Step-by-step explanation:

In this expression the x is the number of blocks  which is multiplied with the height of the block and added to  the height of the base to get the total height of the wall.

Suppose we have ten blocks so

0.6x+ 0.4 = 0.6(10)+ 0.4= 6+0.4= 6.4

The height of the wall would be 6.4 if there are ten blocks.

The height of the wall depends on the number of blocks used.

The height of the base is constant irrespective of the number of blocks used.

Answer:

0.4 represents the height of the base.

0.6 represents the height of each block.

Answer:

-10,6

Step-by-step explanation:

f(x) = (x + 2)^2 - 64

Set equal to zero

0 = (x + 2)^2 - 64

Add 64 to each side

64  = (x + 2)^2

Take the square root of each side

±sqrt(64) = sqrt((x + 2)^2 )

±8 = x+2

Subtract 2 from each side

±8-2 = x

-8-2 =x

8-2 = x

Hope this helps :)

Answer:

Step-by-step explanation:

f(x) = x - 2

g(x) = x²

In order to find (fog)(-1) we must first find (fog)(x)

To find (fog)(x) substitute the g(x) into f(x) that's for every x in f (x) replace it with

g (x).

That's

(fog)(x) = x² - 2

To find (fog)(-1) substitute the value of x that's - 1 into (fog)(x)

We have

(fog)(-1) = (-1)² - 2 = 1 - 2 = - 1

Answer:

Step-by-step explanation:

Factoring is aided by having the equations in standard form. The first step in each case is to put the equations in that form. The zero product property tells you that a product is zero when a factor is zero. The solutions are the values of x that make the factors zero.

Answer:

C(x) = 5700 + 500x

Step-by-step explanation:

Total cost = fixed cost + variable cost

Fixed cost are cost that do not change in the process of production such as machineries, furnitures & fittings.

Variable cost are cost that changes with production such as cost of raw material, cost of labor.

From the question:

Fixed cost= $5,700

Cost per unit of computer = $500

If x number of computers are produced in a month

Variable cost = 500x

Total cost = fixed cost + variable cost

C(x) = 5700 + 500x

Where,

C(x) = total cost

5700= fixed cost

500x= variable cost

Answer:

C(x)=500x+5700.

Step-by-step explanation:

he general Cost function formula is given by

C(x)=cost per unit⋅x+fixed costs.

The manufacturer has fixed costs of $5700 no matter how many computers it produces. In addition to the fixed costs, the manufacturer also spends $500 to produce each computer. If we substitute these values into the general cost function, we find that the cost function when x computers are manufactured is given by

C(x)=500x+5700.

Hey there!

The measure of angle ABD plus the measure of angle CBD equals 90 degrees or a right angle.

Thus, we can write the equation: ABD+51=90

Solving for ABD, we find that it is 39 degrees.

Let me know if this helps :)

the value of ∠ABD is 3[tex]9^{o}[/tex] degrees.

A right angle is an angle of 90°. When two rays intersect and form a 90˚ angle or are perpendicular to each other at the intersection, they are said to form a right angle.

according to given figure

The measure of angle ∠ABD plus the measure of angle  ∠CBD equals 90 degrees or a right angle.

Thus, we can write the equation: ∠ABD + ∠CBD = 9[tex]0^{o}[/tex]

∠ABD + 5[tex]1^{o}[/tex] = 9[tex]0^{o}[/tex]

∠ABD = 9[tex]0^{o}[/tex] - 5[tex]1^{o}[/tex]

∠ABD = 3[tex]9^{0}[/tex]

Hence, the value of ∠ABD is 3[tex]9^{o}[/tex] degrees.
