  7 = prime

  9 = 3^2

  6 = 3·2

The LCM is 7·3^2·2 = 126

showing what equal it is to it

The perimeter of each polygon created by the coordinates is 15.2 units

The coordinates are given as:

A(-2, 3), B(3, 1), C(-2, -1), D(-3, 1)

Calculate the distance between each point using

d = √(x2 - x1)^2+ (y2 - y1)^2

So, we have:

dAB = √(-2 - 3)^2+ (3 - 1)^2 = 5.4

dBC = √(3 + 2)^2+ (1 + 1)^2 = 5.4

dCD = √(-2 + 3)^2+ (-1 - 1)^2 = 2.2

dDA = √(-3 + 2)^2+ (1 - 3)^2 = 2.2

The perimeter is calculated as:

P = 5.4 + 5.4 + 2.2 + 2.2

Evaluate

P = 15.2

Hence, the perimeter of each polygon created by the coordinates is 15.2 units

Answer:

Ok, we know that the width of the door is 4.20m.

Then, if the arc is at the top of the door, we will have that the diameter of that "half circle" will be equal to the width of the door.

Then the diameter of the arc is 4.20m

And the radius is defined as half of the diameter, so we have:

radius = 4.20m/2 = 2.10m

And we can write this in cm (because the probelm ask for it)

1m = 100cm

then 2.10m = 2.1*100cm = 210cm

Now, we know that the perimeter of a circle is:

P = 2*pi*r

where pi = 3.14

Then the perimeter (or arc) of half a circle will be half of that:

Arc = (2*pi*r)/2 = pi*r

and r = 210cm, pi = 3.14

Arc = 3.14*210cm = 659.4cm

Step-by-step explanation:

Any 4 numbers can be added to the sequence starting with 10. Perhaps you're supposed to use a rule to choose the numbers. For any 4 numbers you might add to the sequence, a rule can be determined.

The rules we usually use are ones that require a constant difference or a constant ratio. The sequence shown above uses the rule that the difference from the previous value is 1 more than the difference between the previous two values.

Step-by-step explanation:

We can convert this word problem into an equation by examining what it  says.

6 times a number

Since we don't know the value of that number, we can represent it as [tex]x[/tex]. 6 times [tex]x[/tex] will be [tex]6x[/tex]

Greater than has this symbol: [tex]>[/tex]

3 less than 4 times a number. We can break this down. 4 times a number is [tex]4x[/tex]. 3 less than that will be [tex]4x-3[/tex].

Combining that all, we get [tex]6x > 4x-3[/tex]

Answer:

To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one.

Step-by-step explanation:

x + y = 5

12x + 9y = 51

x = 5 - y

12(5 - y) + 9y = 51

60 - 12y + 9y = 51

-3y + 60 = 51

-3y = 51 - 60

-3y = -9

y = -9/-3

y = 3

x = 5 - y

x = 5 - 3

x = 2

I cant answer that, I need a picture to the question Step-by-step explanation:

Responda:

3,91 m

Explicação passo a passo:

Dado o seguinte:

Comprimento da escada = 4,3 m

Distância da base da parede = 1,8m

Altura da parede =?

O problema pode ser resolvido usando Pitágoras:

hipoteno = sqrt (oposto² + adjacente ²)

Hipoteno = comprimento da escada = 4,3

4,3 = sqrt (1,8² + altura²)

Quadrar ambos os lados

4,3² = 1,8² + altura²

4,3² - 1,8² = altura²

18,49 - 3,24 = altura²

15. 25 = altura²

Tire a raiz quadrada de ambos os lados

Sqrt (15,25) = altura

Altura = 3,905

Altura = 3,91 m

Answer:

∠64° and ∠26°

Step-by-step explanation:

Complementary angles add up to 90° total (two angles).

Lets give variable values to each angle:

x= 12 more than twice the measure of the complement

y= complement

Write an equation equaling to a total of 90:

[tex]x+y=90[/tex]

Write an algebraic expression for the value of x:

[tex]12+2y[/tex]

Insert the value for x into the equation:

[tex]12+2y+y=90[/tex]

Simplify and solve for y:

[tex]12+3y=90\\\\12-12+3y=90-12\\\\3y=78\\\\\frac{3y}{3}=\frac{78}{3}\\\\ y=26[/tex]

The value of y is 26. Insert this value into the original equation and solve for x:

[tex]x+26=90\\\\x+26-26=90-26\\\\x=64[/tex]

The value of x is 64. So, the complemenatry angles are 64° and 26°.

:Done

From the given measure whose angle is  12° more than twice the measure of its complement.

The measure of the two angles is 64° and 26° respectively.

Complementary angles are angles whose sum is equal to 90°. It is usually composed of two angles complementing themselves. Hence, the term complementary angles.

Mathematically;

∴

p + q = 90°    ( complemntary angles)

If one of the angles is 12 more than twice its complement;

i.e.

Let p = 12

SO, the algebraic equation for the value of p is:

12 + 2q = 90

Replacing the value of q to solve the equation, we have:

12 + 2q + q = 90

12 + 3q = 90

3q = 90 - 12

3q = 78

q = 78/3

q = 26°

From p + q = 90°    ( complemntary angles)

Replacing the value of q = 26°, we have:

p + 26° = 90°

p = 90° - 26°

p = 64°

In conclusion, the measure of each angle is 64° and 26°.
