Answer:

15

Step-by-step explanation:

We know that the expression is equal to 110° since it is a vertical angle. So what we do is we ad 10 to both sides of the equation. We are left with 8x=120 so if we divide 120/8 we get 15 which would leave it as x=15. Now plug it in and check it.

Answer:

C) I only

Step-by-step explanation:

( -1, -2) and (0,4)

Slope:

m=(y2-y1)/(x2-x1)

m=(4+2)/(0+1)

m=6/1

m=6

Slope-intercept:

y - y1 = m(x - x1)

y + 2 = 6(x + 1)

y + 2 = 6x + 6

y = 6x + 4

y - 16 = 6(x - 2)

y - 16 = 6x - 12

y = 6x + 4

Answer:

my guess would be 15 because it goes down by 5s

Answer:

If two angles in standard position have the same terminal side, they are called coterminal angles.

The reference angle is the acute angle (the smallest angle) formed by the terminal side of the given angle and the x-axis.

Angle of Rotation is the measurement of the amount of the angle, by which a figure is rotated counterclockwise about a fixed point, often the center of a circle. Usually clockwise rotation is called as Negative rotation

If two angles in standard position have the same terminal side, they are called coterminal angles.

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

Coterminal angles are those angles that share the terminal side of an angle occupying the standard position. The standard position means that one side of the angle is fixed along the positive x-axis, and the vertex is located at the origin.

The reference angle is the acute angle (the smallest angle) formed by the terminal side of the given angle and the x-axis.

Angle of Rotation is the measurement of the amount of the angle, by which a figure is rotated counterclockwise about a fixed point, often the center of a circle. Usually clockwise rotation is called as Negative rotation.

Hence, if two angles in standard position have the same terminal side, they are called coterminal angles.

Answer:

(i) La sustracción de números naturales no es cerrada, puesto que no existe el resultado cuando el minuendo en menor que el sustraendo, es decir:

[tex]2 - 5 = -3, -3\notin \mathbb{N}[/tex]

(ii) La sustracción de números naturales no es conmutativa, pues al cambiar las posiciones entre minuendo y sustraendo, se pasar de un resultado contenido en [tex]\mathbb{N}[/tex] a uno no contenido en ese cuerpo. Es decir, el resultado cambia. Es decir:

[tex]5 - 2 = 3[/tex]

[tex]2 - 5 = -3, -3\notin \mathbb{N}[/tex]

(iii) La sustracción de números naturales no asociativa, pues al cambiar la posición de los paréntesis, puede llevar a un resultado distinto o inexistente en [tex]\mathbb{N}[/tex] debido a que el signo afecta a todo lo que está adentro del paréntesis. Es decir:

Answer:

[tex]540\pi[/tex]

Step-by-step explanation:

Given,

Diameter of the cylinder = 12cm

Radius of the cylinder = 12cm ÷ 2 = 6cm

Height of the cylinder = 15cm

Therefore,

Volume of the cylinder

[tex] = \pi {r}^{2} h[/tex]

[tex] = \pi \times 6 \times 6 \times 15 {cm}^{3} [/tex]

[tex] = 540\pi \: cubic \: cm[/tex]

Hence,

Option 2 is correct for volume of the cylinder in cubic cm:

Answer:

Ahmed got 390 votes

Step-by-step explanation:

Here, we want to know the number of votes obtained by Ahmed

from the question, there were 900 registered voters

10% did not cast their votes

The number that didn’t cast their votes will be;

10% of 900

= 10/100 * 900 = 90

So the rest 90% casted and this value will be 900-90 = 810

810 people casted their votes

30 votes were spoilt;

The number of valid votes is thus;

810 - 30 = 780

Ahmed got a ratio of 3 in 3:2:1

The total value here is 3 + 2 + 1 = 6

So what Ahmed got will be;

3/6 * 780

= 780/2 = 390

Heart if this helped

Answer:

x=1 and y=4

Step-by-step explanation:

Let's solve your system by substitution.

3x−6y=−21;6x−9y=−30

Step: Solve3x−6y=−21for x:

3x−6y=−21

3x−6y+6y=−21+6y(Add 6y to both sides)

3x=6y−21

x=2y−7

Substitute2y−7for x in6x−9y=−30:

6x−9y=−30

6(2y−7)−9y=−30

3y−42=−30(Simplify both sides of the equation)

3y−42+42=−30+42(Add 42 to both sides)

3y=12

y= 4

Substitute4foryinx=2y−7:

x=2y−7

x=(2)(4)−7

x=1(Simplify both sides of the equation)
