Find the perimeter

Answers

Answer:

ANSWER

GIVEN:

OA= 3x-1 , OC= 5x-3, OD= 6x-5 , BO = 2x+1

AO/OC = BO/OD

[The diagonals of a Trapezium divide each other proportionally]

(3x-1)/(5x-3) =( 2x+1)/(6x-5)

(3x-1) (6x-5) = (5x-3) ( 2x+1)

3x(6x-5) -1 (6x-5) = 2x(5x-3)+1(5x-3)

18x² -15x -6x +5 = 10x² -6x +5x -3

18x² -21x +5 = 10x² - x -3

18x² -10x² -21x + x +5+3 =0

8x² - 20x +8= 0

4(2x² -5x +2) = 0

2x² -5x +2 = 0

2x² -4x -x +2= 0

[By factorization]

2x(x-2) -1(x-2)= 0

(2x-1) (x-2) = 0

(2x-1) = 0 or (x-2) = 0

x = ½ or x = 2

If we put x= ½ in OD , The value of OD is negative.

Hence, the value of is x = 2.

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Event:  getting a 6 on a number cube

P( getting a 6 on a number cube) = 7/40

The true statements are:

1) The relationship is proportional

2) y = -3x is equation of the line.

3) The slope is negative.

What is a slope?

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction

A graph of the line is given.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

And line passes through the points (4, -12) and (6, -18).

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

m = -3

The slope is negative.

Then the equation of the line is,

y + 12 = -3(x -4)

y + 12 = -3x + 12

y = -3x

This equation shows the proportional relationship.

Therefore, all the required values are given above.

In the two plays combined, the team gained 5 yards. D Over 5 weeks, Alyson withdraws $25 per week from her checking account. Altogether, she withdraws $125.

Answers

Answer and explanation:

Not sure if the question is complete or valid but I will explain each option:

Let's assume the question asks which of the options would provide a negative result of -25( as no option evaluates to -255)

A. There would be a negative result here since all golfers have a negative score of -5 after 9 holes, and therefore a total score of -25 for all five golfers

B. Temperature increases by 25 degrees after 5 hours hence 5 degrees increase for every 1 hour. This would obviously give a positive result.

C. A football team gains 25 yards in the first play and loses 5 yards in the second but has a result of 5 yards gained in total. Hence there was a penalty of losing 20 yards for a loss of 5 yards= 25 yards- 20 yards= 5yards

D. Alyson withdraws $25 every week for 5 weeks, therefore she withdraws $125 in 5 weeks. This would be a negative result of -$125.

∵ CB ⊥ BE

DF // CB

∵ D is the mid-point of CE

∵ DF // CB

F is the mid-point of EB

∵ DF joining the mid-points of EB and EC

∴ DF = [tex]\frac{1}{2}[/tex] CB

∵ CB = f and DF = 4 ft

∴ 4 = [tex]\frac{1}{2}[/tex] f

→ Multiply both sides by 2

8 = f

Harper simplemente encendió una vela nueva y luego la dejó arder hasta la nada. La longitud de la vela que permanece sin quemar, en pulgadas, se puede modelar mediante la ecuación L = 15-1.5t, L = 15−1.5t, donde tt representa el número de horas desde que se encendió la vela. ¿Cuál es la pendiente de la ecuación y cuál es su interpretación en el contexto del problema?

Answers

Answer:

La pendiente de la ecuación es -1.5 y su interpretación en el contexto del problema es que en este caso este valor indica que la longitud L de la vela luego de t horas desde que se encendió la decrece en 1.5 unidades por cada hora.

Step-by-step explanation:

La función lineal se define por la ecuación

f(x) = mx + b

o

y = mx + b

donde m es la pendiente de la recta y b es la ordenada al origen.

La gráfica de una función lineal es siempre una recta.

Como se mencionó, la m es la pendiente de la recta. La pendiente es la inclinación con respecto al eje x, que es el eje de abscisas.

La pendiente m significa que si aumentamos la x en una unidad, la y aumenta en m unidades. Si m es positiva (m > 0), entonces la función es creciente. En cambio, si la m es negativa (m < 0), entonces la función es decreciente.

En este caso, siendo L=1.5 - 1.5t y comparando con la expresión y=mx + b, podes observar que el valor de la pendiente m es -1.5. Como m es un número negativo, entonces se trata de una función decreciente. En este caso este valor de pendiente indica entonces que la longitud L de la vela luego de t horas desde que se encendió la decrece en 1.5 unidades por cada hora.

La pendiente de la ecuación es -1.5 y su interpretación en el contexto del problema es que en este caso este valor indica que la longitud L de la vela luego de t horas desde que se encendió la decrece en 1.5 unidades por cada hora.

In the figure below, m angle WXZ=113°, and m angle2 is 3° more then m angle1 Find m angle1

Answers

Answer:

m∠1 = 55° ; m∠2 = 58°

Step-by-step explanation:

Let m∠1 = x° , then m∠2 = x° + 3°

m∠1 + m∠2 = 113°

x° + x° + 3° = 113°

2x + 3 = 113

2x = 110

x = 55°

m∠1 = 55° and m∠2 = 58°

The value of m∠[tex]1[/tex] is [tex]55[/tex]° and m∠[tex]2[/tex] is [tex]58[/tex]°

In the given figure m∠WXZ = [tex]113[/tex]° and m∠[tex]2[/tex] is [tex]3[/tex]° more than  m∠[tex]1[/tex].

What is angle?

An angle is formed when two rays are joined together at a common point.

Now,

Let  m∠[tex]1[/tex] = x° and m∠[tex]2[/tex] = x° + 3°

According to given figure;

m∠[tex]1[/tex] +  m∠[tex]2[/tex] = 113°

x° + x° + 3° = 113°

2x° + 3° = 113°

2x° = 110°

x° = 55°

Hence, the value of  m∠[tex]1[/tex] = x° = 55° and m∠[tex]2[/tex] = 55° + 3° = 58°
