Kate begins solving the equation StartFraction 2 Over 3 EndFraction left-parenthesis 6 x minus 3 right-parenthesis equals StartF

raction one-half EndFraction left-parenthesis 6 x minus 4 left-parenthesis.(6x – 3) = StartFraction 2 Over 3 EndFraction left-parenthesis 6 x minus 3 right-parenthesis equals StartFraction one-half EndFraction left-parenthesis 6 x minus 4 left-parenthesis.(6x – 4). Her work is correct and is shown below. StartFraction 2 Over 3 EndFraction left-parenthesis 6 x minus 3 right-parenthesis equals StartFraction one-half EndFraction left-parenthesis 6 x minus 4 left-parenthesis.(6x – 3) = StartFraction 2 Over 3 EndFraction left-parenthesis 6 x minus 3 right-parenthesis equals StartFraction one-half EndFraction left-parenthesis 6 x minus 4 left-parenthesis.(6x – 4) 4x – 2 = 3x – 2 When she adds 2 to both sides, the equation 4x = 3x results. Which solution will best illustrate what happens to x ? The equation has infinite solutions. The equation has one solution: x = 0. The equation has one solution: x = StartFraction 4 Over 3 EndFraction.. The equation has no solution.

Answer:

(B) There is a single solution: x = 0.

Step-by-step explanation:

The equation that Kate is attempting to solve is: \dfrac{2}{3} (6x-3)=\dfrac{1}{2}(6x-4)

\dfrac{2(6x-3)}{3}=\dfrac{(6x-4)}{2}\\\dfrac{2*3(2x-1)}{3}=\dfrac{2(3x-2)}{2}\\4x-2=3x-2\\$Adding two both sides$\\4x=3x\\4x-3x=0\\x=0

Consequently, this equation results in one solution: x = 0.

A truck with a heavy load drove from Boston to New York at 50 mph. After dropping of the load, it returned from New York to Bost
Zina [3914]

Answer:

175/3 or 58.333...

Step-by-step explanation:

This problem can be complex, but I'll simplify it. I apologize for the challenges involved in formatting fractions correctly. To ensure accuracy, I've added several parentheses that may seem unnecessary.

Let d denote the distance between the two cities.

The time it takes can be expressed as d/r, where r represents the speed; thus, from B to NY, it is d/50.

In the same manner, from NY to B, it's d/70.

The average velocity can be determined as 2d divided by the sum of d/50 and d/70, representing the average time.

Next, eliminate d from the equation to reach (d/d)*2/(1/50+1/70).

Now, you can multiply by the Least Common Multiple (LCM) over itself, which is 350/350.

The result after performing this calculation will yield 700/12, equating to 58.333...(This is how you would enter it into your RSM browser) I hope this clarification is useful. My apologies for the delay.

In a study of exercise, a large group of male runners walk on a treadmill for six minutes. Their heart rates in beats per minute
Leona [4166]

Answer:

a) 1.88% de los corredores tienen frecuencias cardíacas superiores a 130.

b) 50% de los no corredores tienen frecuencias cardíacas superiores a 130.

Explicación paso a paso:

Los problemas relacionados con muestras distribuidas normalmente pueden resolverse utilizando la fórmula del puntaje z.

En un conjunto con media \mu y desviación estándar \sigma, el puntaje z asociado a una medida X se presenta a través de:

Z = \frac{X - \mu}{\sigma}

El puntaje z indica cuántas desviaciones estándar está la medida respecto a la media. Tras determinar el puntaje z, consultamos la tabla de puntajes z y localizamos el valor p relacionado con este puntaje. Este valor p representa la probabilidad de que el valor de la medida sea menor que X, es decir, el percentil de X. Al restar 1 del valor p, obtenemos la probabilidad de que el valor de la medida sea mayor que X.

(a) ¿Qué porcentaje de los corredores tienen frecuencias cardíacas superiores a 130?

En un estudio sobre ejercicio, un gran grupo de corredores masculinos camina en una caminadora durante seis minutos. Sus frecuencias cardíacas expresadas en latidos por minuto al final varían entre ellos conforme a la distribución N(104,12.5). Esto implica que \mu = 104, \sigma = 12.5.

Este porcentaje es 1 menos el valor p cuando X = 130.

Z = \frac{X - \mu}{\sigma}

Z = \frac{130 - 104}{12.5}

Z = 2.08

Z = 2.08 tiene un valor p de 0.9812.

Esto significa que 1-0.9812 = 0.0188 = 1.88% de los corredores tienen frecuencias cardíacas superiores a 130.

(b) ¿Qué porcentaje de los no corredores tienen frecuencias cardíacas superiores a 130?

Las frecuencias cardíacas para hombres no corredores después del mismo ejercicio mantienen la distribución N(130, 17). Esto implica que \mu = 130, \sigma = 17.

Este porcentaje es 1 menos el valor p cuando X = 130.

Z = \frac{X - \mu}{\sigma}

Z = \frac{130 - 130}{17}

Z = 0.00

Z = 0.00 tiene un valor p de 0.5000.

Esto significa que 1-0.50 = 0.50 = 50% de los no corredores tienen frecuencias cardíacas superiores a 130.

Read the proof. Given: m∠H = 30°, m∠J = 50°, m∠P = 50°, m∠N = 100° Prove: △HKJ ~ △LNP Statement Reason 1. m∠H = 30°, m∠J = 50°,
zzz [4022]

Answer:

2. m\angle H+m\angle J +m\angle K =180^{\circ}

Reason: the total sum of all angles inside any triangle equals 180º.

Step-by-step explanation:

1) Organization

Statement 1. m∠H = 30°, m∠J = 50°, m∠P = 50°, m∠N = 100° 1. Reason: given

2) Given that the sum of all internal angles in any triangle is always 180º, similar to the formula. N represents the number of sides of a triangle:

S_{i}=180^{\circ}(n-2)\rightarrow 180(3-2) \therefore S_{i}=180^{\circ}

3) We can also state

m\angle K=180^{\circ}-(m\angle H+m\angle J)\\m\angle K=180^{\circ}-\left ( 30^{\circ}+50^{\circ} \right )\\m\angle K=100^{\circ}

Like in the other triangle:

m\angle L=180^{\circ}-(m\angle N+m\angle P)\\m\angle L=180^{\circ}-\left ( 100^{\circ}+50^{\circ} \right )\\m\angle L=30^{\circ}

4) Therefore,

2. m\angle H+m\angle J +m\angle K =180

Reason: The total of the internal angles is equal to 180º.

What is the concentration of a new solution obtained by mixing 25ml of water with 125ml of a 20% salt solution in water?
babunello [3635]
Given that the salt concentration in a 125 ml salt solution is at 20%, it indicates a salt to water ratio of 20:80, which simplifies to 1:4.

Consequently, the salt quantity in the 125 ml 20% solution can be calculated as 20% of 125, yielding 0.2 x 125 = 25 ml, and therefore, the water content amounts to 125 - 25 = 100 ml.

When adding 25 ml of water to this 20% salt solution, the total water becomes 100 + 25 = 125 ml while the salt quantity remains at 25 ml.

Thus, the new total volume of the solution is 125 + 25 = 150 ml, leading to a salt proportion in the updated mixture of 25/150 = 0.1667.

As a result, the concentration of the new solution <span>after mixing 25 ml of water with 125 ml of a 20% salt solution is 16.67%</span>
