Answer:

Area = 14.5

Step-by-step explanation:

Let's label the given coordinates A, B, C;

Thus;

A = (2, 3)

B = (-1, 0)

C = (2, -4)

From the coordinate geometry formula, the formula for area of a triangle with 3 vertices is;

Area = [Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By)]/2

Area = [2(0 - (-4)) + (-1)(-4 - 3) + 2(3 - (-4))]/2

Area = 29/2

Area = 14.5

by considering  4 + 5 = 259

5² = 25

4 + 5 = 9  

by considering  6 + 7 = 4913

7² = 49

Answer:

1/4 of a yard of material

Step-by-step explanation:

First, we must convert both 12 1/4 yards and 8 1/2 yards to quarters. Since 1/2 of a yard is equal to 2/4 of a yard, 8 1/2 yards will be equal to 8 2/4 yards. 8 yards + 12 yards = 20 yards, and 2/4 of a yard + 1/4 of a yard = 3/4 of a yard, so you get 20 3/4 of a yard to finish the draperies. To find the leftover material, do 21 yards - 20 3/4 yards = 1/4 of a yard of material. Hope this helps!

Answer:

Step-by-step explanation:

1 . ( n + 4 ) / ( 2m - 3 )

The gradient (slope) is

= ( change in y direction ) / ( change in x direction )

= ( n - (-4) ) / ( 2m - 3 )

= ( n + 4 ) / ( 2m - 3 )

2.

A line parallel to the x-axis will always have the equation of y = #. This is because all along that line, every value of x, y will still equal the same number. For example, a line parallel to the x-axis that crosses the y-axis at 2, will be y = 2. If it is in the negative range, it's the same concept, for example if it crossed the y-axis at -4, the equation would be y = -4.

Example - Computational Knowledge Engine

3.

To understand the slope of a line parallel to y axis, let us consider the figure given below.

1 . The gradient (slope) is ( n + 4 ) / ( 2m - 3 )

2. n = -4

3. m is not defined.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

points (2m, n) and (3, -4).

1 . The gradient (slope) is

= ( change in y direction ) / ( change in x direction )

= ( n - (-4) ) / ( 2m - 3 )

= ( n + 4 ) / ( 2m - 3 )

2. A line parallel to the x-axis will always have the equation of y = x.

The line is therefore horizontal so gradient = 0

(n+4) / (2m-3)= 0

n = -4

(iii) Find the value of m if the line is parallel to the y-axis

(n+4) / (2m-3)= gradient

(n+4) / (2m-3)= 1

We know n = -4 from part (ii) then

(-4+4) /(2m-3)= 1

0/(2m-3) = 1

0 = 1 The 'm' vanishes

Hence, m is not defined.

Answer:

Step-by-step explanation:

M is the midpoint. SO length of XM  equals length of MY

MY = XM

9x + 12 = 5x + 8

Subtract 12 from both sides

9x  = 5x  +8 - 12

9x = 5x  - 4

Subtract 5x from both sides

9x - 5x = -4

      4x = -4

Divide both sides by 4

x = -4/4

x = -1

XY = 5x + 8

     = 5*(-1) + 8

     = -5 + 8

XY = 3

MY = 9x + 12

     = 9*(-1)1 + 12

     = -9 + 12

MY = 3

X Y = 3+3

XY = 6

What is the means of a proportion?

1 : harmonious relation of parts to each other or to the whole : balance, symmetry. 2a : proper or equal share each did her proportion of the work. b : quota, percentage. 3 : the relation of one part to another or to the whole with respect to magnitude, quantity, or degree : ratio.

A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "twenty is to twenty-five as four is to five."

please correct me if im wrong

Answer:

D

Given the proportion

[tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex]

Then a and d are the extremes of the proportion

and b, c are the means of the proportion

brainliest and 20 points! Which best explains whether or not ΔABC ≅ ΔLMN? The figures are congruent because a 270° rotation about the origin and then a reflection over the x-axis will map ΔABC onto ΔLMN. The figures are congruent because a 90 rotation about the origin and then a reflection over the x-axis will map ΔABC onto ΔLMN. The figures are not congruent because point B corresponds with point N and point C corresponds with point M. The figures are not congruent because there is no rigid transformation or combination of rigid transformations that will map ΔABC onto ΔLMN.

Answer: h = 14

Step-by-step explanation:

7h-5(3h-8)-56 = -128

7h -15h+40-56 = -128

or, -8h-16= -128

or, -8h = -128 + 16

or, -8h = -112

or, 8h = 112

or, h = 112/8

so, h = 14

Answer:

h = 14

Step-by-step explanation:

We are going to use basic algebra to solve this equation.

First, let's isolate the h variables by moving -56 to the other side:

7h - 5(3h - 8) - 56 = -128

(add 56 to both sides)

7h - 5(3h - 8) = -72

Next, let's distribute the -5 to (3h - 8) by separating it from the equation then adding it back:

7h - 5(3h - 8) = -72

Separation:

-5(3h - 8) --> (-5*3h) + (-5*-8) --> (-15h) + (40)

-15h + 40

Adding it back in:

7h -15h +40 = -72

Next, let's simplify it down by adding like terms, meaning adding 7h & -15h:

7h -15h +40 = -72

(add 7h & -15h)

-8h + 40 = -72

Now we're going to move the 40 to the other side but subtracting 40:

-8h + 40 = -72

(subtract 40 to both sides)

-8h = -112

Finally, we're going to divide both sides by -8

-8h = -112 --> h = 14

The answer is h = 14

(You can double check by plugging 14 into the equation and see if it equals -128, which it does, so it's correct :-) )

Answer:

3x + 5 = 23

Step-by-step explanation:

Let x represents the number of persons in her group.

Since she brings 3 markers for each person, then number of markers brought for persons in her group = 3x.

She brings 5 extra markers for each person to share.

Thus, total markers she brought is now;

3x + 5

She brought 23 markers in all.

Thus, equation that represents the information is;

3x + 5 = 23

Answer:

x = 16

Step-by-step explanation:

Since the numbers are in ascending order, x is the number with the highest value here.

From the arrangement, we can see that the median (the middle number) is the third number which is 9

The mean is the sum of the numbers divided by their count. So we set up the mean and equate to the median

We have this as;

(1 + 9 + 9 + 10 + x)/5 = 9

29 + x = 5(9)

29 + x = 45

x = 45-29

x = 16

Answer:

The area of each section of the circle is 25\pi\ m^{2}25π m2

Step-by-step explanation:

we know that

The area of a circle is equal to

A=\pi r^{2}A=πr2

we have

r=10\ mr=10 m

substitute

A=\pi (10^{2})=100\pi\ m^{2}A=π(102)=100π m2

To find the area of each section divide the complete area of the circle by 44

so

100\pi\ m^{2}/4=25\pi\ m^{2}100π m2/4=25π m2

Note: The values in the table are not correct because the sum of the probability of all events is not equal to one. The should be 0.13 and 0.33 instead of 0.113 and 0.133 respectively.

Given:

The probability distribution for a random variable x is given in the table.

x     :    -5          -3            -2            0           2          3

P(x) :  0.17      0.13       0.33       0.16       0.11      0.10

To find:

The probability of -2.

Solution:

From the given probability distribution for a random variable x, it is clear that the value of the probability is 0.33 corresponding to -2.

[tex]P(-2)=0.33[/tex]

Therefore, the probability of -2 is 0.33.
