Answer:

Lets say a CD costs a 100 dollars (which it obviosly doesn't)

No matter whether we do the discount before or after tax, it'll end up costing 84 dollars to by the CD.

80% of 100 = 80

80 * 1.05 = 84

80% of 105 = 84

The order in which he does the discount and the tax doesn't matter.

A straight line of numbers is shown visually as a number line. This line is used to compare integers on an endless line that extends on both sides, either horizontally or vertically, at equal intervals. On a horizontal number line, the numbers grow as we walk to the right and drop as we move to the left.

A number line is a visual depiction of numbers on a straight line drawn either horizontally or vertically. It is simple for humans to compare numbers and carry out simple arithmetic operations on them when they are written down on a number line. A number line is said to begin at zero (0). Left of zero, there are only negative numbers, and right of zero, there are only positive numbers. So, on a number line, we may say that the value of numbers grows as we travel to the right. This indicates that there are more numbers on the right than on the left.

Answer:

A. 5,420

Step-by-step explanation:

4 in 542 is in the tens place and 4 in 5,420 is in the hundreds.

The number A. 5420 has a 4 that is 10 times greater than the 4 in 542.

The standard decimal form of numbers is written in base 10 as there are 10 different numbers from 0 to 9.

Each digit has a face value and a place value.

The expanded form of 542 is 5×100 + 4×10 + 4.

So, 10 times greater than it should be a multiple of 100 or a digit in the hundreds place.

From the given options the number 5420 in the expanded form is,

5×1000 + 4×100 + 2×10 + 0.

So, The number 5420 has a 4 that is 10 times greater than the 4 in 542.

The polynomial function is V(x) = x^3 - 7x^2 + 10x and domain of x is (5,6]

Here we are given that the length of the box is x

Also, the width of the box should be 5 feet shorter than the length

Thus, width = x - 5

and the height should be 3 feet longer than the width

Thus, height = x - 5 + 3

= x - 2

Now the volume of the box = length × width × height

Volume = x (x-5) (x-2)

V(x) = (x^2 - 5x) (x-2)

V(x) = x^3 - 2x^2 - 5x^2 + 10x

V(x) = x^3 - 7x^2 + 10x

Now, looking at the options, we see that option C is eliminated.

Now, let us look at the domain of x

Since width cannot be negative (x-5) > 0

⇒ x > 5

Now in option A domain is (0, 6], but x cannot take values from (0,5). Thus, option A is eliminated.

Similarly, we can eliminate option B also since x cannot take values from (0, 2)

Thus, option 4 is the correct answer.

The missing side of the figure if the perimeter is 35 2/3 cm, is calculated as: 10.9 cm.

The perimeter of a figure is the total length surrounding the figure.

We are given that the figure shown below has a perimeter of 35 2/3 cm, which means all the total length of all its sides equals 35 2/3 cm.

To find the missing length, sum all the given lengths and subtract it from the perimeter of the figure.

Sum of all the given lengths =  4 3/4 + 3 1/2 + 1 1/3 + 1 1/3 + 3 1/2 + 9.25 + 6.6 = 4.75 + 2.3 + 1.3 + 1.3 + 2.3 + 9.25 + 6.6

The answer we got is a complex number.

We are asked to find out the multiplication of a complex number and a real number.

The general form of a complex number is a + bi.

If we need to find the product of a complex number and a real number,

then, we need to multiply the real and imaginary parts by the real number and write down the answer.

The real number given is 2.

And the complex number given is 12 - 11i.

The real part of the complex number is 12.

And the imaginary part of the complex number is -11.

When the real part of the complex number is multiplied by the real number, we get 12 × 2 = 24.

When the imaginary part of the complex number is multiplied by the real number, we get (-11) × 2 = -22

Step-by-step explanation:

Using measures of variability, it is found that:

a. The situations with constant measures involve constant distributions, such as the number of snow days in Miami each year.

b. The situations with different measures involve constant distributions, such as the number of snow days in Buffalo each year.

There are three measures of variability in a data-set: the range, the standard deviation and the variance.

The range is given by the difference between the maximum value and the minimum value of a data-set.

The standard deviation and the variance are described as follows:

Uniform(constants) data-sets will have similar measures. One example is the number of snow days in Miami each year, which is always of 0, hence the three measures will be of 0.

More disperse data-set will have different measures. Taking the city of Buffalo, in New York, as an example. On average, it should have 40 days of snow each winter, but on colder winters it can have 60 and warmer winters it can have 20. Hence the distribution with the number of snow days in Buffalo over a period of 20 years will have different range, standard deviation and variances.

Step-by-step explanation:

Drone nerds will get 15 Mavic air 2's for $23196.192 after offering a chain discount of 6/4/3.

Chain discount is the series of discounts that are offered from the list price of an object when bought from a store.

A general example of a 10/5 chain discount denotes that there will be a series of discounts on the list price. First a discount of 10% is awarded on the list price then a further 5% on the reduced price.

The List price of the drones is $26500.

Chain discount=6/4/3

So the first discount received is 6% on the $26500.

Price after the first discount=26500- 6%of 26500

Simplifying we get

[tex]=26500-.06\times26500\\=24910[/tex]

The price after the first discount is $24910

Now we will apply the 4% discount on $24910

Price after second discount=24910-4% of 24910

=$23913.60

Now we apply the third discount

Price after third discount is=23913.60-3%of 23913.60

The value of x is 64 and the property that justifies that action is  the multiplication property of equality.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

Mathematical statements are called expressions if they contain at least two terms that are connected by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations.

As an illustration, the expression x + y is one where x and y are terms with an addition operator in between. There are two types of expressions in mathematics: numerical expressions, which only contain numbers, and algebraic expressions, which also include variables.

We have an expression:

x/4 = 16

Apply Multiplication property of equality:

Multiply by 4 on both sides:

(x/4)4 = 16×4

x = 64
