In the diagram below, (5, 2) is the midpoint of a segment with one endpoint (-1,8). What is the other endpoint of the segment? Show your work or explain how you find your answer.

The rational numbers arranged on a number line will graduate from the highest to the lowest (left to right) as follows:

A rational number is defined in mathematics as the quotient or fraction p/q of two integers, a numerator p, and a non-zero denominator q. For example, −4/7 is a rational number, as is every integer.

Note that a number line is defined as a horizontal line with evenly spaced numerical increments.

To get the order in which the numbers must be arranged, the trick is to convert the number for which you have doubt into their decimal forms or d integer forms.

A) √16 = 4

B) 2/3 = 0.6

C) |-3| = 3 {Reason: Absolute Value of any number must be its positive equivalent]

D) 2.47 x 10^{-2} = 0.0247

E) -1/4 = -0.25

Hence rearranged in descending order (from highest to lowest) we have:

On the number line, the first nubmer from the left will be √16, followed by |-3|, and so on.

Answer:

D. When a transversal crosses parallel lines, the corresponding angles are congruent.

Step-by-step explanation:

This is quite self-explanatory. It is pretty well-explained in the textbook if you're looking for guidance, practice, or more help.

You need to remember these four theorems:

- Corresponding Angles Theorem

   - If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.

- Alternate Interior Angles Theorem

   - If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.

- Alternate Exterior Angles Theorem

   - If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent.

- Consecutive Interior Angles Theorem

   - If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles are supplementary.

Answer:

width=x

length=x+8

area= x(x+8)

new width =x+2

new length=x+10

New Area = (x+2)(x+10)

(x+2)(x+10)-x(x+8)= 68

after solving:

4x=68-20

4x=48

x=12

width=12m

length=12+8=20m

Answer: what

Step-by-step explanation:

The equation of the line graph in slope intercept form is gotten as;

y = x + 3

The general formula for the equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Now, from the given straight line equation graph, we can see that the line crosses the x-intercept at x = -3 and crosses the y-intercept at y = 3. Thus;

When x = 0, y = 3

When y = 0, x = -3

Slope is gotten by using two points and their coordinates to get;

m = (3 - 0)/(0 - (-3))

m = 3/3

m = 1

Thus, the equation of the line is y = x + 3

The diagram shows a semi-circle inside a rectangle of length 150 m.

The semi-circle touches the rectangle at A, B and C,  the perimeter of shaded region is 267.8m

Perimeter of a circle =  2 πr

Thus, as per the diagram given:

Length of rectangle = 150 m

The radius of semi circle = half of 150 m = 75 m

So, the width of the circle is same as radius = 75 m

The shaded region is bounded by the circumference of a quarter circle (AB) and the two sides measuring it are 75 m each.

Perimeter of Quarter circle = 2πr

On substituting r

Perimeter of Quarter circle = 2π x 75

Perimeter of the shaded region = 117 + 75 + 75 = 267.8 m

The diagram shows a semi-circle inside a rectangle of length 150 m. The semi-circle touches the rectangle at A, B and C,  the perimeter of the shaded region is 267.8m

Step-by-step explanation:

Fixed costs = $ 1329.50 per month

Variable cost are $3.70 per set of napkins

Total cost she set aside = $1870 for monthly costs

Amount left for napkins = Total cost - Fixed Cost

= 1870 - 1329.50

Cost for one set = $3.70

Let set of napkins = x

Total cost for napkins = $540.50

Therefore , she can afford to make 147 (approx) sets of napkins per month.

After factorization, the absolute value of the variable 'x' is 9.

What is factorization method?

The factorization method is used for the quadratic based equation whose highest degree is either two or more than two. Depending upon the degree of the variable, the number of factors are calculated. And by substituting the calculated value to check whether the answer is correct or not.

According to the question, the given linear equation is: |2x - 4| = 15

Now, to calculate the value of the variable 'x' by using factorization method. And to remove the bars which represent absolute value that means positive values

Required expression: |2x - 4| = 15

⇒ 2x = 15 + 4 = 19

⇒ x = 19/2 = 9.5

Answer:

A and C

Step-by-step explanation:

Piecewise functions have multiple pieces of curves/lines where each piece corresponds to its definition over an interval.

Given piecewise function:

[tex]f(x)=\begin{cases}2x \quad &\text{if }x < 1\\5 \quad &\text{if }x=1\\x^2 \quad &\text{if }x > 1\end{cases}[/tex]

Therefore, the function has three definitions:

[tex]\textsf{A.} \quad f(1) =5[/tex]

This statement is true as when x = 1, f(x) = 5.

[tex]\textsf{B.} \quad f(5)=1[/tex]

This statement is false as when x is greater than 1, f(x) = x²:

[tex]\implies f(5)=(5)^2=25[/tex]

[tex]\textsf{C.} \quad f(2)=4[/tex]

This statement is true as when x is greater than 1, f(x) = x²:

[tex]\implies f(2)=(2)^2=4[/tex]

[tex]\textsf{D.} \quad f(-2)=4[/tex]

This statement is false as when x is less than 1, f(x) = 2x:

The number that must be added to the positive difference of 4³/10 and 7⅔ to obtain 25​ is 21 [tex]\frac{19}{30}[/tex]

A mixed number is a non-integer that is made up of a whole number, a numerator and a denominator. An example of a mixed number is 21 [tex]\frac{19}{30}[/tex].

The first step is to determine the positive difference between the mixed numbers. If the difference is positive, it means that the smaller fraction was subtracted from the larger fraction.[tex]7\frac{2}{3} - 4\frac{3}{10}[/tex]

[tex]3\frac{20 - 9}{30}[/tex] = [tex]3\frac{11}{30}[/tex]

The wind speed when the air pressure is 20kpa will be 954.36 miles per hour.

From the information, there is a close relationship between the air pressure inside a hurricane and its maximum sustained wind speed: y = -0.932x + 973.

where x = the air pressure in millibars (kPa) l

y = wind speed in knots (nautical miles per hour).

Therefore, the wind speed when the air pressure is 20kpa will be calculated thus:

y = -0.932x + 973.

y = -0.932(20) + 973.

y = -18.64 + 973

A closed triangle has three vertices, three sides, and three angles. The symbol for a triangle with the three vertices P, Q, and R is PQR. Sandwiches and signboards in the shape of triangles are the most prevalent triangle-shaped objects.

A triangle has an obtuse angle if one of the inner angles is greater than 90 degrees. In an obtuse triangle, if one angle is greater than 90°, the total of the other two angles is also less than 90°.

As the triangle B have one interior angle as 126 degree which is greater than 90

so it follows the property of obtuse triangle
