Hey It's Chloe again, sorry.
But what is the perimeter of a rectangle?

Answers

Answer 1

Answer:A perimeter is the sides of a shape added together.

Step-by-step explanation:

Answer 2

Answer:

The perimeter of a rectangle is the total length of all the sides of the rectangle.

Step-by-step explanation:

The perimeter of a rectangle is the total length of all the sides of the rectangle. We can find the perimeter by adding all four sides of a rectangle. Since opposite sides of a rectangle are always equal, we need to find the dimensions of only two sides to find the perimeter of a rectangle.

If you have a 2 inches by 4 inches rectangle, you would have 2 inches + 4 inches + 2 inches + 4 inches = 12 inches

Please help!! Given that triangle ABC is congruent to triangle DEF, the measure of angle A = 70°, the measure of angle B = 60°, the measure of angle C = 50°, the measure of angle D = (3x + 10)°, the measure of angle E = (y/3 + 20)°, and the measure of angle F = (z^2 + 14)°, find the values of x, y, and z.

Answers

Answer:

Ok so since the triangles are congruent, that means that the corresponding angles are congruent. This means angle A = angle D, angle B = angle E, and angle C = angle F.

So:

angle A = angle D

70 = 3x + 10

3x + 10 = 70

3x = 60

x = 20

angle B = angle E

60 = y/3 + 20

y/3 + 20 = 60

y/3 = 40

y = 120

angle C = angle F

50 = z^2 + 14

z^2 + 14 = 50

z^2 = 36

z = 6 (or -6)

Step-by-step explanation:

Simplificando

6x + -2 + 2x = -2 + 4x + 8

Reordenar los términos:

-2 + 6x + 2x = -2 + 4x + 8

Combinar términos semejantes: 6x + 2x = 8x

-2 + 8x = -2 + 4x + 8

Reordenar los términos:

-2 + 8x = -2 + 8 + 4x

Combinar términos semejantes: -2 + 8 = 6

-2 + 8x = 6 + 4x

Solving

-2 + 8x = 6 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.

-2 + 8x + -4x = 6 + 4x + -4x

Combine like terms: 8x + -4x = 4x

-2 + 4x = 6 + 4x + -4x

Combine like terms: 4x + -4x = 0

-2 + 4x = 6 + 0

-2 + 4x = 6

Add '2' to each side of the equation.

-2 + 2 + 4x = 6 + 2

Combine like terms: -2 + 2 = 0

0 + 4x = 6 + 2

4x = 6 + 2

Combine like terms: 6 + 2 = 8

4x = 8

Divide each side by '4'.

x = 2

Simplifying

x = 2

Do the ratios 4/2 and 10/5 form a proportion? Yes or no

Answers

Answer:

These are both 20 so that means that this is proportional, yes.

Step-by-step explanation:

Hi.

To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.

Here is how we do this.

[tex]\frac{4}{2}[/tex]    [tex]\frac{10}{5}[/tex]

So basically what we are doing is multiplying across in a diagonal direction.

Diagonal meaning like a slash / .

So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.

Do the same for the 2 and the 10.

So we have to multiply :

4 x 5

2 x 10

=

20

These are both 20 so that means that this is proportional, yes.

Hope this helps.

If you have any questions or concerns feel free to message me.

Yes the ratios 4/2 and 10/5 form a proportion.

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

4/2, 10/5

Si para introducirun producto al país se pagan $225 por concepto de impuestos y dicho producto cuesta $1,200

Answers

Complete question :

si para introducir un producto al país se pagan $225 por concepto de impuestos y dicho producto cuesta $1,200 ¿que porcentaje se cobra por impuesto?

Responder:

18,75%

Explicación paso a paso:

Dado que:

Monto cobrado por impuestos = $ 225

Costo del producto sujeto a impuestos = $ 1200

El porcentaje del precio de costo del producto que se grava:

Sea porcentaje = x%

x% * precio de coste = importe de impuestos

0.01x * $ 1200 = $ 225

12x = 225

x = 225/12

x = 18,75

Por tanto, porcentaje de impuesto = 18,75%
