900km is less than the perimeter of the of Bhutan about 1075km.

The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimeters, meters, inches, and feet.

The length of a shape's outline is its perimeter. You must add the lengths of all four sides of a rectangle or square to determine its perimeter. In this instance, x represents the rectangle's length and y its width. The surface of a shape's area is measured.

Answer:

  -8k -2

Step-by-step explanation:

You want the simplified form of -2(k+1)-6k.

The process of simplifying an algebraic expression includes ...

Parentheses are removed using the distributive property. The factor outside parentheses multiplies each term inside.

  -2(k +1) -6k

  = (-2)(k) +(-2)(1) -6k = -2k -2 -6k

Terms with the same variable content can be combined by adding their coefficients. (The distributive property is involved here, too.)

  = (-2 -6)k -2 = -8k -2

The simplified expression is -8k -2.

[tex](2x + 3x + 4x) = 180 \\ 9x = 18 \\ \frac{9x}{9} = \frac{180}{9} \\ x = 20[/tex]

ATTACHED IS THE SOLUTION with the steps.

Answer:

x = 4 , x = 2.4

Step-by-step explanation:

[tex]\frac{4}{x-2}[/tex] + [tex]\frac{3}{x-3}[/tex] = 5

multiply through by (x - 2)(x - 3)

4(x - 3) + 3(x - 2) = 5(x - 2)(x - 3)

4x - 12 + 3x - 6 = 5(x² - 5x + 6)

7x - 18 = 5x² - 25x + 30 ( subtract 7x - 18 from both sides )

0 = 5x²  - 32x + 48

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 5 × 48 = 240 and sum = - 32

the factors are - 20 and - 12

use these factors to split the x- term

0 = 5x² - 20x - 12x + 48 ( factor the first/second and third/fourth terms )

0 = 5x(x - 4) - 12(x - 4) ← factor out (x - 4) from each term

0 = (x - 4)(5x - 12)

equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

5x - 12 = 0 ⇒ 5x = 12 ⇒ x = 2.4

Answer:Rotation then a translation

Step-by-step explanation: rotate 90 degrees clockwise around center J. Then translate 3 to the right, 2 down

Step-by-step explanation:

Since area = 27cm²

area = 3 × (x + 4)

27 = 3(x + 4)

expand the right side

27 = 3x + 12

move 12 to the left side and subtract it with 27

15=3x

then divide both sides with 3

x=5

The given equation is

5(x - 3) = x + 13

We want to test if x = 6 is a solution. We would substitute x = 6 into the equation. We have

5(6 - 3) = 6 + 13?

5(3) = 6 + 13?

15 = 19?

Since both sides of the equation is not equal, then

x = 6 is not a solution of the equation

The equation is 10x=2x+60

 x=15/2

∠CFH=75

∠CBD= 75

We are dealing with parallel lines, which are the lines that are equidistant to each other and never meet,  will never meet, when such lines are crossed by another line called the transversal creates many angles such as corresponding angles, vertical angles, alternate interior angles, alternate exterior angles, consecutive angles.

Since, angle CBD and angle CFH are the corresponding angles and they are equal to each other, we are given CBD=2x+60 and CFH = 10x

therefore , 10x=2x+60

=>10x-2x=60

=>8x=60

x=15/2

So, the angle CBD= 2x+60= 2(15/2)+60=  75

Answer: y-intercept (0,−2) and the slope is 1/3

According to the solving the space between Arthur and Jamie are 39.1 meters.

A coordinate system is a method for determining how to place points or other geometrical objects on a manifold, such as Euclidean space, uniquely using one or more numbers, or coordinates.

The length of the line segment bridging two locations in a plane is known as the distance between them. d=√((x2 – x1)² + (y2 – y1)²).  is a typical formula for determining the separation between two places. Any two sites on an x-y plane or coordinate plane can have their distance between them calculated using this equation.

location of Arthur is (20, 30)

location of Jamie is (45, 60)

Let's apply the rule of distance to determine how far away they are because we know that :

d = √((X₂ - X₁)² + (Y₂ - Y₁)²)

let substituting the value we get:

d = √((X₂ - X₁)² + (Y₂ - Y₁)²)

d = √((45 - 20)² + (60 - 30)²)

=   √(25)² + (30)²)

= 39.1

According to the solving the space between Arthur and Jamie are 39.1 meters.

It takes Phindi to run almost 22 tracks to cover 12kms

Given that,

First you have to figure out the length of the track whihc is circumference of circle ,

r is the radius  of circular track which is 88m

The athlete has to run 12km on the track

Circumference of circle = 2πr

Solving circumference will give length of the circular track which is,

Circumference of circle = 2(3.14)(88)

                                          =552.6 meters

If she covers 552.6 m whe runs one circular track then,

1 circular track -------- 552.6 meters

? circular track -------- 12000 meters or 12 kilometers

No of circular tracks = 12000/552.6 = 21.7 tracks

Assuming the question is : How much does x liters/milimeters of oil weigh?

First, we calculate how much mass did the bottle of oil lose : 590 - 400 = 190 (grams)

Since it loses 190 grams after Sophia uses 200 milimeters of oil, 200 milimeters of oil weighs 190 grams (yes.)

-> 1 milimeter of oil weighs : 190/200 = 0.95(grams)

So, to calculate the mass of x *liters* of oil, we take 0,95 x 1000 times x.

For example : To calculate the mass of 22,5 liters of oil, we take 0,95 x 1000 x 22,5 = 21375 (g) or 21.35(kg).

The equation of S in terms of N is S(N) = 2200 + 40N

From the question, the given parameters are

Monthly salary = $2200

Additional earnings = $40 per copy of Math fun sold

The equation that relates S to N is then calculated as

Total = Monthly salary + Additional earnings x Number of copy of Math fun sold

Substitute the known values in the above equation

So, we have

S(N) = 2200 + 40N

So, the equation is S(N) = 2200 + 40N
