Se sabe que los catetos de un triangulo rectangulo miden 0,4 cm y 0,3 cm. Micaela dice que su perimetro es igual a 1,2 cm ¿Sera cierto? De no ser asi , determina el valor del perimetro correcto

Answers

Answer 1

Answer:

El perímetro es de 1.2 cm

Step-by-step explanation:

La formula del perímetro de un triángulo rectángulo es:

p = cateto1 + cateto2 + hipotenusa

Para determinar el valor de la hipotenusa usamos el Teorema de Pitágoras:

hipotenusa² = cateto1² + cateto2²

hipotenusa² = 0.4² + 0.3²

hipotenusa² = 0.16 + 0.09

hipotenusa² = 0.25

√hipotenusa² = √0.25

hipotenusa = 0.5

entonces, el perímetro es:

p = 0.4 + 0.3 + 0.5

p = 1.2cm

por tanto

Micaela tiene razón, el perímetro es de:

1.2 cm

Which linear equation below represents the line that goes through the point (3.4) and has a slope of 2?

Answers

Answer:

Linear equation with a slope of 2 that goes through the point (3, 4) is [tex]y = 2\cdot x -2[/tex].

Step-by-step explanation:

From statement we know the slope of the line and a point contained in it. Using the slope-point equation of the line is the quickest approach to determine the appropriate equation, whose expression is:

[tex]y-y_{o} = m \cdot (x-x_{o})[/tex]

Where:

[tex]m[/tex] - Slope, dimensionless.

[tex]x_{o}[/tex], [tex]y_{o}[/tex] - Components of given point, dimensionless.

[tex]x[/tex], [tex]y[/tex] - Independent and dependent variable, dimensionless.

If we know that [tex]m = 2[/tex], [tex]x_{o} = 3[/tex] and [tex]y_{o} = 4[/tex], the linear equation is found after algebraic handling:

1) [tex]y-4 = 2\cdot (x-3)[/tex] Given

2) [tex]y = 2\cdot (x-3) +4[/tex] Compatibility with Addition/Existence of Additive Inverse/Modulative Property

3) [tex]y = 2\cdot x -2[/tex] Distributive Property/[tex](-a)\cdot b = -a\cdot b[/tex]/Definition of sum/Result

Linear equation with a slope of 2 that goes through the point (3, 4) is [tex]y = 2\cdot x -2[/tex].

You want to start a business selling lanyards to hang your mask from. You have $25 in your banking account to purchase the materials you would need to make them. After doing some research for the best deals it is going to cost you $45 to make 10 lanyards (the minimum you can make).

Answers

Answer:

If the minimum is 10 and it costs $45 for that you would be going into the negatives as $25 is less then $45 meaning : You do not have enough money to purchase something that is $45. You would need $20 more dollars. If there was no minimum you would only be able to buy 4 with a few dollars left over.

In a community garden shown to the right you want to plan a fence in a vegetable garden that is adjacent to your friends Garden you have at most 44 ft of fence and the fence must around all four sides of your garden what is the possible lengths of your garden ​

Answers

Answer:

Length of the garden = 13 ft

Width of the garden = 9 ft

Step-by-step explanation:

Let the length of my new garden = l ft

It's given in the question,

width of the garden = 9 ft

Formula to calculate the perimeter of a rectangle is,

P = 2(L + W)

Where L = length of the garden

W = width of the garden

P = perimeter of the garden

Length of the fence = 44 ft

By substituting values in the formula,

44 = 2(l + 9)

22 = l + 9

l = 22 - 9

l = 13 ft

Therefore, length of my new garden = 13 ft

Width of the garden = 9 ft

Answers

Answer:

A reflection across the Y-axis

Step-by-step explanation:

The single transformation can map figure PQRS onto image P'Q'R'S' is a reflection.

Given that, the coordinates of figure PQRS are P(2,2) Q(5,2) R(5,6) and S (2,6) and the coordinates of the image P'Q'R'S' are P'(-6,2) Q'(-3,2), R'(-3,6) and S' (-6,6).

What is transformation?

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and image, after transformation, refers to the object's ultimate shape and location.

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point.

The figure PQRS is reflected on the y-axis and translated left to 1 unit.

Therefore, the single transformation can map figure PQRS onto image P'Q'R'S' is a reflection.

x= 12 y= 9

Step-by-step explanation:

x+29=3x+5

-x

29=2x+5

-5

2x=24

/2 /2

x=12

12+29=41

180-41= 139+5= 144÷16=9

x = 12 , y = 9
you set the “x” equations equal to each other to simply and find “x” . once you find “x” you simplify “x+29” ( equals 41) , add it to the “y” equation and set the entire equation (16y - 5 + 41) equal to 180° (16y - 5 + 41 = 180) since that’s what a line is equal to and then solve ! hope i helped :)

Markus decides to return 4 shirts costing $19 each to a clothing store. While there, he decides to purchase 2 pairs of shoes at $45 each and a raincoat for $62.75. The clerk charges him 5% tax on the amount due after returns. What amount does he owe the clerk?

Answers

Answer:

$80.59

Step-by-step explanation:

You add the price of the raincoat and shoes to get 152.75, you then subtract the price of the 4 shirts you returned to get 76.75. The 5% tax for this is 3.84 so you add the two together and you get $80.59.

What are some examples of Adjacent Congruent Angles.

Answers

Answer:

base angles of an isosceles triangleangles at successive corners of any regular polygonangles either side of an angle bisectorangles made by a perpendicular to a line (excluding vertical angles)

Step-by-step explanation:

When it comes to angles, the term "adjacent" means different things in different contexts. Any pair of angles in a triangle are considered to be adjacent. The base angles of an isosceles triangle are adjacent congruent angles.

Angles at successive corners of any regular polygon are congruent adjacent angles.

Angle that have a common vertex and a common side are also called adjacent angles. Angles on either side of an angle bisector are adjacent congruent angles. Likewise any non-vertical pair of angles where lines cross at right angles are adjacent congruent angles.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The system of equations are:

5x + y = 2

2y = 4 − 10x

The system of equations can be written as:

5x + y = 2 ..(I)

10x + 2y = 4 ...(II)

In equation (II) divide by 2

5x + y = 2 ..(III)
