Find the value if x=2+root3

Answer:

40 in

Step-by-step explanation:

36/12=3

24/3=8

12+12+8+8=40

The perimeter of the floor in the scale drawing is 40 inches.

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

If the rectangular floor of the classroom has a length of 36 feet and a width of 24 feet, then the perimeter of the floor can be calculated as:

P = 2L + 2W

P = 2(36) + 2(24)

P = 72 + 48

P = 120 feet

We are given that the scale drawing of the floor has a length of 12 inches. This means that 12 inches on the scale drawing represent 36 feet in real life.

To find the perimeter in inches on the scale drawing, we can use the following proportion:

12 inches / 36 feet

= x inches / 120 feet

Simplifying this proportion, we get:

x = (12 inches / 36 feet) x 120 feet

x = 40 inches

Therefore,

The perimeter of the floor in the scale drawing is 40 inches.

Answer:

The complex number would be in the 4th quadrant.

Step-by-step explanation:

We know that a complex number is a number that can be expressed in the form of a + bi,

where

Given the complex number

10 - 13i

Here,

As the coefficient of the imaginary part holds a negative sign, and the real part holds a positive sign.

Thus, the complex number would be in the 4th quadrant.

Answer:

8,3 y=3x+4

Step-by-step explanation:

The y intercept of line AB is 56/5 and the equation of the line CD is y = -7/5 x + 12.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Given A(8, 0) and B(3, 7).

Equation of line in slope intercept form is y = mx + c, where m is the slope and c is the y intercept.

Slope of AB = (7 - 0) / (3 - 8) = -7/5

Substituting in the equation,

y = -7/5 x + c

Substituting a point (8, 0) on the equation,

0 = (-7/5 × 8) + c

c = 56 / 5

Given AB parallel to CD.

Slope of parallel lines are equal.

Slope of CD is -7/5.

Equation of the line CD is y = -7/5 x + c.

Substituting (5, 5),

5 = (-7/5 × 5) + c

c = 12

Equation of CD is y = -7/5 x + 12

Hence the equation of line CD is y = -7/5 x + 12.

Step-by-step explanation:

Answer:

YES, because the points fall in a straight line when plotted on a graph.

Step-by-step explanation:

To graph these numbers we can take two of the points and put them into two point form and then convert that to slope intercept form.

Zachary bought 16 ounces of juice

Step-by-step explanation:

First you figure out how many ounces are in a pint ( Which in case your wondering it's 16)

Then you take that number and divide $3.20 by 16 which gives you .20 cents.

You can double check my answer by multiplying .20 by 16 which gives you $3.20.

Answer: 3 Pencils

Step-by-step explanation:

In order to know how many packages Zayed can make, we need a number that is a factor of 72 and 24, so that the 72 pencils and the 24 calculators can be divided evenly.

So, if there wre 2 packages, there would be 72 / 2 = 36 pencils 24/ 2= 12 calculators in each package. This creates packages, but isn't the gratest number of packages!

To find the greatest number of identical packeges, we want to found the greatest common factor of 72 and 24

To do so, lets find the factors of 72 and 24

72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

24: 1, 2, 3, 4, 6, 8, 12, 24

the gratest common number factor of 72 and 24 is 24. in math notation this looks like:

gcf (72, 24)=24

the gratest number of identical packages can make is 24

To find the umber of pencils in each pacage, we need to dovide the total number of pencils by the number of pakages:

72 / 24 = 3.

there will be 3 pencils each package

  x = 7

Step-by-step explanation:

We assume the hash marks are intended to indicate both triangles are isosceles. Then the right-end angle of the upper triangle is ...

  180° -2(75°) = 30°

Its complement is the supplement of the "missing variable" angle.

  90° -30° = 180° -(18x -6)°

  18x = 126 . . . . . rearranging (add 18x -60)

Answer:

The given equation will have two roots as +5i and -5i

Step-by-step explanation:

Shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero for this function

The given equation is [tex]x^2+25 =0[/tex]

This clearly shows it will have complex roots, and since it is a quadratic equation it will have 2 complex roots

[tex]x^2 = -25 \\x = \sqrt{-25} \\x= \sqrt{-1}* \sqrt{25}\\[/tex]

[tex]x = i\sqrt{25}[/tex]

x = ± 5i

It will be false to say that -5i will be the only complex root to this equation.

The given equation will have +5i and -5i as its roots.

Lets verify

x = +5i

[tex](5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25\\-25 + 25 = 0[/tex]

x = -5i

[tex](-5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25 \\-25 + 25 \\ = 0[/tex]

Plz Brain -list the answer  It takes effort tnx dear

Step-by-step explanation:

From given condition

equation of line is given as,

x*cos(α)+y*sin(α)=p

& as tanα= 5/12 so from Pythagoras theorem

sinα=  5/13

​cosα=  12/13

⇒12x+5y=39

p = 3, α = tan-1 (5/12) So, tan α = 5/12 sin α = 5/13 cos α = 12/13 The equation of the line in normal form is given by By using the formula, x cos α + y sin α = p Now, substitute the values, we get 12x/13 + 5y/13 = 3 12x + 5y = 39 ∴

Answer:

False

Step-by-step explanation:

Look at the inputs (x-values)

If the inputs are the same, the relationship is Not a function.

Inputs (x-values), cannot share the same output (y-values).

Example:

Inputs      Outputs

3              2    

2              5

8              5

3              6

In the input there are two 3's which causes this to not be a function.

(Outputs can have the same numbers repeating just not inputs.)

x = 9

Step-by-step explanation:

combine all the equations and set it equal to 360

10x+ 7 + 88 + 127 + 5x+3 = 360

then combine like terms

15x + 225 = 360

then solve the equation by moving 225 to the right side of the equation

15x = 135

divide both sides by 15

x = 9
