in the diagram, what is the value of x

Answer:

Step-by-step explanation:

The last one -- D -- is the closest correct answer. None of them, however, is right.

y = -1/4 x + 8                      Let x = - 8

y = -1/4 * - 8   +  8              The standard rule is starting from the left, do the multiplication first then do the addition

- 1/4 * - 8 will first of all give you a positive result. When 2 minuses are multiplied they give a positive answer.

-1/4 * - 8 = 1/4 * 8

1/4 * 8 = 2

y = 2 + 8

y = 10

So the ordered pair (-8 , 10) is the answer.

Answer:

BAC and DAE are two acronyms for BAC and DAE, respectively. Since they are angles at a point, an arc measuring 204 degrees is 360 degrees. BAC is measured at 11 degrees. 5(11)° = 55° is the measure of DAE.

Answer: 1 1/12 yards

Step-by-step explanation:

Since Ciara needs 2 ⅓ yards of fabric for the shawl and also needs 1 ¾ yards of fabric for the dress, the total yards needed will be:

= 2⅓ + 1¾

= 2 4/12 + 1 9/12

= 3 13/12

= 4 1/12 yards

Since she has 3 yards of fabric, the number of yards needed more will be:

= 4 1/12 - 3

= 1 1/12

Therefore, she needs 1 1/12 yards more.

Area:  200.96 cm

Circumference:  50.24 cm

Explanation: I recently just learned this.  The area of a circle is Pi times radius squared which makes.  3.14 x 8^2 = 3.14 x 64 = 200.96.  SInce none of the original measurements are squared it will be    200.96 cm

The circumference of a circle is diameter times pi which makes  3.14 x (8 x 2) = 3.14 x 16 = 50.24.  Since none of the original measurements are squared it will be 50.24 cm

What they mean is if you substitute the value given for x into the equation given, is the math statement true.

Step-by-step explanation:

1) Is x = -3 a solution to 6x + 4 = -12?

6(-3) + 4 = -18 + 4 = - 14, so no, for number 1, x = -3 is not a solution to 6x + 4 = -12

Make sense?

Answer:

$30.41

Step-by-step explanation:

To find the tax she paid take the total amount times the rate of tax

24.20x.05=1.21

Then add the tax to the amount she paid before tax was added and the tip

$1.21+$24.20+$5=$30.41

So she spent $30.41 at the restaurant

Answer:

  g(x) = x^2/25

Step-by-step explanation:

For a horizontal stretch by a factor of k, x is replaced by x/k.

  g(x) = f(x/5) = (x/5)^2 = x^2/25

The new function is ...

  g(x) = x^2/25

Pregunta completa:

Calcula el volumen de un prisma cuya base es un hexágono regular con un lado de 3 cm y un área lateral de 18√3 cm ^ 2.

Respuesta:

81/2 cm²

Explicación paso a paso:

El hexágono tiene 6 lados

Longitud de cada lado, L = 3 cm

Por lo tanto, perímetro = 3 * 6 = 18 cm

Área lateral, A = perímetro * altura

A = 18√3; P = 18

18√3 = 18 * h

h = 18√3 / 18

h = √3

Área base = perímetro * apotema / 2

Apotema = raíz cuadrada (3² - (3/2) ²)

Apotema = raíz cuadrada (9 - 9/4)

Apotema = (36 - 9) / 4 = raíz cuadrada (27/4) = √27 / 2

Área base = 18 * √27 / 4 = 9√27 / 2 = 9√9 * 3/2 = 27 / 2√3

Volumen = área de la base * altura

Volumen = 27 / 2√3 * √3

Volumen = 81/2 cm²

Answer:

3 4/15 km²

7 7/15 km

Step-by-step explanation:

Please find attached an image showing the dimensions of the farm

Here is the complete question :

A farmer's field has the dimension shown He needs to find the area of the field so that he knows how much seed to buy, and the perimeter so he can buy the fencing. Using the model find the area and perimeter of the field.

area of a rectangle = length x breadth

1 2/5 x 2 1/3

convert the mixed fractions to improper fractions

7/5 x 7/3 = 49/15 = 3 4/15 km²

Perimeter of a rectangle = 2 x (length + breadth)

2 x (1 2/5 + 21/3)

2([tex]1\frac{2}{5} + 2\frac{1}{3}[/tex])

2([tex]3\frac{6 + 5}{15}[/tex])

2([tex]3\frac{11}{15}[/tex])

2 x 56/15 = 112/15 = 7 7/15 km

Answer:

130

Step-by-step explanation:

since bc and bd equal the same thing, plug in every answer option until you get to 360.

(130 x 2) = 260

plus cd = 100.

260 + 100 = 360.

The arc length is twice the inscribed angle.

The sum of the three angles must be 180.

The measure of the arc length BC is 130°

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Triangle BCD is isosceles and BC ≅ BD.

Isosceles triangle C B D has points on the circle.

The measure of arc CD is 100 degrees.

This means,

We know that the arc length is twice the inscribed angle.

2 x Angle B = CD

2 x Angle B = 100

Angle B = 100/2

Angle B = 50

Now,

In an isosceles triangle, the angle opposite to the equal sides must be equal.

The sum of the three angles must be 180.

x + x + 50 = 180

2x = 180 - 150

2x = 130

x = 65

Now,

We know that the arc length is twice the inscribed angle.

So,

The measure of the arc length BC.

= 2 x 65

= 130°

Thus,

The measure of the arc length BC is 130°

i dont know

Answer: For 1, the answer is B since there is no rational number for sqrt17.

For 2, the answer is C since it has to be less than 11 whose square is 121 and larger than 10 whose squre is 100.

For 3 the answer is B. Just plug the x value into the equation. => y=1/2(-1)-2 => y= -1/2-2 => -2 1/2.

For 4 the answer is A because the graph first goes up then stys their staticly for a while then plumets down. It fits the description of the first one.
