What Is The Value Of X?

Answers

Answer 1

Answer:

x = 3

Step-by-step explanation:

CD is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is

[tex]\frac{BD}{AD}[/tex] = [tex]\frac{BC}{AC}[/tex] ( substitute values )

[tex]\frac{x}{2.25}[/tex] = [tex]\frac{4}{3}[/tex] ( cross- multiply )

3x = 4 × 2.25 = 9 ( divide both sides by 3 )

x = 3

JM is equal to 9, ZW is 13.5, JK is 12, and WX is 18.

To obtain the coordinates of the other shape, multiply the original shape by the scale factor

What is the scale factor?

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2.

13.5 / 9 = 1.5

9 * 1.5 = 13.5 \s12 * 1.5 = 18

You have a scale factor of 1.5. (because if u multiply 1.5 by the original shape, u get the new shape)

JKLM ~ WXYZ

So  JK ~  WX

So the scale factor  =  WX / JK

Scale Factor   =  18 / 12 =   3 / 2    =   1.5

(−2,−4), (1,0), (1,5), (−2,9), (−7,9), (−10,5), (−10,0), (−7,−4)

Answers

The perimeter of the equilateral polygon with the given vertices is given as follows:

40 units.

How to obtain the perimeter of the polygon?

The perimeter of a polygon is composed by the sum of the lengths of the outer edges of the figure.

From the figure given at the end of the answer, the parameters for the polygon with these given vertices are given as follows:

8 side lengths.Each side length is of 5 units. (as the polygon is equilateral, meaning that the side lengths are equal).

Then, considering the 8 side lengths and the fact that they measure 5 inches, the perimeter of the polygon is given as follows:

Perimeter = 8 x 5 = 40 units.

(sum of 8 times the number 5 is equals to the multiplication of eight by five).

Amy needs to write a paper that contains more than 3,305 words for school. She has already written 1,450 words and writes at a rate of 265 words per day. Which of the following inequalities could be used to solve for x, the number of days it will take Amy to finish her paper?

Answers

Inequality that could be used to solve for x is;

1450 words + (265 words / day)x  = 3305 words

What is an equation?

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given that Amy has already written 1450 words out of 3305 words.

And she writes at the rate of 265 words per day.

To establish the inequality which could be used to solve for x,

Then Firstly, we will form an equation for the total number of days required to write her paper,

1450 words + (265 words / day)x  = 3305 words.

Simplifying the above expression,

(265 words / day)x = 3305 words - 1450 words

To solve this linear equation, we'll find x = 7.

x = { 3305 words - 1450 words} / 265  words

x = 7 days.

Hence, inequality that could be used to solve for x is;

1450 words + (265 words / day)x  = 3305 words

Answers

The coordinates of the centroid of triangle DEF with the vertices (0,4) (6,6), and (2,2) is calculated as: (8/3, 4).

How to Find the Coordinates of the Centroid of a Triangle?

The formula for finding the coordinates of the centroid of a triangle is given as:

C(x, y) = [tex]( \frac{(x1+x2+x3)}{3}, ( \frac{(y1+y2+y3)}{3})[/tex].

Given the vertices of triangle DEF as follows:

D (0, 4) = [tex](x_1, y_1)[/tex]

E (6, 6) = [tex](x_2, y_2)[/tex]

F (2, 2) = [tex](x_3, y_3)[/tex]

Substitute the values into the centroid formula to find the coordinates:

C(x, y) = [(0 + 6 + 2)/3, (4 + 6 + 2)/3]

C(x, y) = (8/3, 12/3)

C(x, y) = (8/3, 4)

Answers

The perimeter of the figure is 5.0.

What is a perimeter?

The perimeter of a two-dimensional shape is the distance around the outside of the shape. It is the sum of the lengths of all the sides of the shape. For example, the perimeter of a rectangle is the sum of the lengths of all four sides. The perimeter of a triangle is the sum of the lengths of all three sides.

To reflect a point across the line y=x, we can use the following formula:

(x', y') = (y, x)

Where (x', y') is the reflected point and (x, y) is the original point.

Using this formula, we can find the coordinates of the reflected points A' and B':

A' = (4, 4) -> (4, 4) -> (4, 4)

B' = (5, -1) -> (-1, 5) -> (-1, 5)

Therefore, the image of AB is A'B' with endpoints A'(4, 4) and B'(-1, 5).

To find the perimeter of the figure formed by the segments AB, B'B, and A'B', we can add up the lengths of these three segments. The length of AB can be found using the distance formula:

[tex]AB = \sqrt{((5-4)^2 + (-1-4)^2)}\\\\= \sqrt{(1^2 + (-5)^2)}\\\\= \sqrt{(1 + 25)}\\\\= \sqrt{26}[/tex]

The length of B'B can be found using the same formula:

[tex]B'B = \sqrt{((-1-(-1))^2 + (5-5)^2)}\\\\= \sqrt{(0^2 + 0^2)}\\\\= 0[/tex]

The length of A'B' can also be found using the distance formula:

[tex]A'B' = \sqrt{((-1-4)^2 + (5-4)^2)}\\\\= \sqrt{(-5)^2 + (1)^2}\\\\= \sqrt{25 + 1}\\\\= \sqrt{26}[/tex]

The perimeter of the figure is AB + B'B + A'B' = √26 + 0 + √26 = 2√26. To the nearest tenth, this is 5.0.

Hence, the perimeter of the figure is 5.0.

Graphs are a visual representation of the relationship between variables that are very useful for humans because they allow them to quickly derive an understanding that would not have been possible from lists of values.

Graph the line with y-intercept -7 and slope 3/2

Answers

We are given the slope and the y-intercept so using the slope-intercept form:

y = mx + b, where m- slope, b- y-intercept.

Substitute values to get:

y = (3/2)x - 7

To graph a line we need two points, one is given, (0, - 7) - the y-intercept.

Find one more point,  take even value of x to cancel the fraction, let it be x = 4, find its y-coordinate:

y = (3/2)*4  - 7 = 6 - 7 = - 1

So our points are:

A(0, - 7) and B(4, - 1)

Plot the points and connect to graph the line.

See below.

The graph of the linear equation:y = (3/2)*x - 7 can be seen in the image at the end.

How to graph the linear equation?

A general linear equation is written as:y = a*x + b

Where a is the slope and b is the y-intercept. Then our linear equation is:y = (3/2)*x - 7

To graph it, we need to know two points in our line, to do so, we evaluate it in two different values of x. if x = 0y = (3/2)*0 - 7y = -7So we have the point (0, -7)

And if x = 2 then:y = (3/2)*2 - 7y = 3 - 7y = -4So we have the point (2, -4)

Now we just need to graph these two points and connect them with a line. You can see the graph below.

Differences

The first differences of the given terms are ...

  18 -12 = 6

  27 -18 = 9

These are not constant, so the sequence is not an arithmetic sequence.

Ratios

The ratios of sequential terms are ...

  18/12 = 1.5

  27/8 = 1.5

These are constant, suggesting the sequence is an exponential sequence. The equation for the n-th term is ...

  an = 12(1.5^(n-1))

what is percentage ?

By dividing the value by the entire value and multiplying the result by 100, one can compute the percentage. The formula for calculating percentage is (value/total value)100%.When a piece of a whole is stated as a percentage, it is not a fraction but rather a number between 0 and 100. There are three percentages: 100% for everything, 50% for half of it, and 0% for the remaining portion.

calculation

25% of new students come from one-parent households, which equals 0.25;

75% of new students come from two-parent households, which is 0.75.

42% of incoming students from homes with only one parent go on to complete their college studies = 0. 42

58 percent of incoming students who come from two-parent households go on to complete their education =0.58

= 0.25 * 0.42 + 0.75 * 0.58 = 0.54 = 54%.

Step-by-step explanation:

A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.

We know that the compound interest is given as

A = P(1 + r)ⁿ

Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.

Tyler's bank account pays a straightforward yearly financing cost of 3.25%. Assume he stores $5,000 in the record and sets aside no extra installments or withdrawals for a long time.

The total value of the account after 3 years will be calculated as,
