Chri want to order DVD over the internet. Each DVD cot $15. 99 and hipping the entire order cot $9. 99. If he can pend no more than $100 , how many DVD could be buy?

Answer:

68cm

Step-by-step explanation:

Because the scale factor is 2, which means the drawing is 2 times smaller than the actual airplane, multiply 34, the length of the wings tip to tip in the drawing by 2.

34 x 2 = 68

Answer: 68 meters

(Hope I'm correct, but read the explanation to make sure)

Step-by-step explanation:

Let's start with what we know. We know that the scale factor is 2, so in our model, from tip to tip, it is 34 cm. However, since the scale factor is 2:
34 * 2 = 68 meters

Let's say Chloe spent X

Then Amy spent 60% more so Amy spent

X+60% of X =X + 0.6X =1.6X

Becky spent 15% of what Chloe spent so amount spent by Becky =15% of X = .15X

Now, in total, they spent 0.15X+ X + 1.6X =2.75X which is given as £55

So , X=55/2.75 = 20

Amount spent by Amy = 1.6X = 1.6 *20 =£32

The transformation from the parent function is a translation by 2 units right and 1 unit up

From the question, we have the following function that can be used in our computation:

f(x) = x³

g(x) = (x − 2)³ - 1

First, we have the transformation to be:

From f(x) = x³ to f'(x) = (x − 2)³

This means the function is translated right by 2 units

Next, we have:

From f'(x) = (x − 2)³ to g(x) = (x − 2)³- 1

This means the function is translated up by 1 unit

Hence, the transformation is 2 units right and 1 unit up

The measures of dilated triangle A'B'C' are A'B'= 4.1 units, A'C'= 2.2 units and B'C'= 4.2 units.

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Given that, center of dilation is P and scale factor is 1/3.

In the given triangle ABC, AB=12.4 units, AC=6.7 units and BC=12.7 units

Now, A'B'=12.4/3

A'B'= 4.1 units

A'C'=6.7/3

A'C'= 2.2 units

B'C'=12.7/3

B'C'= 4.2 units

Answer:  The correct answer is 0.0165041148268188

Step-by-step explanation:

Complete division (no rounding precision):

0.442 ÷ 26.7812 = 0.0165041148268188

The area of a rectangle is 42 quare millimeter. The length is 7 millimeter. 28 millimeters is the perimeter of the rectangle.

Perimeter = 2 × (Length + Width)

Perimeter = 2 × (7 + 6)

Perimeter = 28 millimeters

To calculate the perimeter of a rectangle, we need to multiply the length and the width of the rectangle, and then multiply that value by 2. In this case, the length is 7 millimeters, and the area is 42 square millimeters. To calculate the width, we can divide the area by the length, which is 42 divided by 7, which is equal to 6. So the width is 6 millimeters. Now we can calculate the perimeter using the formula: Perimeter = 2 × (Length + Width). Plugging in the values, we get: Perimeter = 2 × (7 + 6) = 28 millimeters.

Examine the sequence. From viewing the first 2 terms, we know that it can either be a geometric sequence that multiplies by 11/3 every time the term increases or an arithmetic sequence that adds 8 every time the term increases.

Looking at the 2nd and 3rd term, we know it is an arithmetic sequence because 19 is not equal to 11 times 11/3.

a) The equation is  y = 4/x².

b) The value of x is 2/9 when y = 25.

What is relationship?

The relation in mathematics is the connection between two or more sets of values. Assume that there are two sets of ordered pairs, x and y. If set x and set y are related, then the values of set x are referred to as the domain while the values of set y are referred to as the range.

Given table is

x      1       2        3          4

y      4       1       4/9       1/4.

Given that y is inversely proportional to the square of x.

y∝ 1/x²

y = k/x² where k is proportional constant.

Putting x = 1 and y = 4 in equation y = k/x²:

4 = k/1²

k = 4

Putting x = 2 and y = 1 in equation y = k/x²:

1 = k/2²

k = 4

Putting k = 4 in  y = k/x²:

y = 4/x²

Putting y = 25 in  y = 4/x²

25 = 4/x²

25x² = 4

Divide both sides by 25:

x² = 4/25

Take square root on both sides:

x = 2/5

The interest amount that will be capitalized is $4.04 million.

The entire cost to purchase a good or service is referred to as an expense. A $30 million piece of equipment with a six-year useful life, for instance, is considered a capital expenditure. An expense is something that calls for the transfer of funds, or fortune in general, from one person or group to another as payment for a good, service, or other type of cost. Rent is a cost to a tenant. Tuition is a cost to parents or students.

The following can be deduced from the information:

Average Expenditure for 2023

= 78 million* 6/6 month + 46 million ** 3/6 month

= 101 million

Amount of interest that should capitalized in 2023 using a specific interest method

= Average expenditure for 2023 * interest rate *6/12 month

We also know that the difference between x and y is 20, so

x - y = 20

Add the two equations to get

Substitute x = 112 into the first equation to get

The required arrangements of tables is  Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < table 7 < Table 6

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

From the given graph it is clear that the line passes through the points (0,0) and (11,20). So, unit rate of graph is

This answer assumes that the function is A(x) = 100x − 2x^2.  The function as written is A(x) = 100x - (4 or 4x)

The domain is 0 - 50 feet.

Step-by-step explanation:

The area function is a polynomial with a vertex (hghest area possible) at (25,1250).  This is telling us that for a side length of 25 feet, the area is at a maximum of 1250 ft^2.  This is actually not totally correct.  We only need 3 sides of fencing since the school wall will make up the fourth.  The given equation does not seem to allow for this caveat, since it uses 100 feet for all four sides.

Given the equation, the domain for the function A(x) is positive for all values between 0 and 50 feet.  The domain is 0 - 50 feet.

The value of x in the solution set of the inequality is -4.

Inequalities are of two types, > and <. The > sign means that left hand side is greater than the right hand side, while the < sign means that the left hand side is less than than the right hand side.

We can solve the inequality by assuming the inequality sign as the = sign, except that when we divide or multiply one side by (-1), the inequality sign will reverse (for eg it will change from > to <).

9(2x+1) < 9x - 18

2x+1 < x - 2

2x < x - 3

x < -3

This means that x can be any value less than -3 (but not equal to -3 since the sign is < and not ≤) . Hence, the answer is -4.

Step-by-step explanation:

The function has no vertical asymptotes and the horizontal asymptotes of the function is y=0.

In the given question,

Consider the following function.

f(x) = e^{−x^2}

We have to find the vertical asymptote(s), x = Find the horizontal asymptote(s) or y = .

As we know that, a vertical asymptote is a line that runs vertically and guides the graph of the function but does not actually exist on it. Due to its position at an x-value that is outside of function's domain, it is difficult for the curve to ever pass it.

The function f(x) = e^{−x^2} has no undefined points. So the function has no vertical asymptotes.

The limit of the function at x→±∞ is calculated as follows:

[tex]\lim_{x\rightarrow \pm\infty }[/tex]f(x) = [tex]\lim_{x\rightarrow \pm\infty }[/tex]e^{−x^2}

[tex]\lim_{x\rightarrow \pm\infty }[/tex]f(x) = 0
