Un automóvil se desplaza 30 1/5 millas en 2/3 de hora. ¿Cuál es la velocidad promedio en millas por hora, del automóvil?

yarga [219]

Queremos encontrar la velocidad promedio de un automóvil dado que conocemos cuanto se desplaza y cuanto tarda en realizar ese desplazamiento. Veremos que la velocidad promedio es 45.3 millas por hora.

Recordar que definimos velocidad promedio como el cociente entre la distancia recorrida y el tiempo que se tarda en recorrer esa distancia.

Aca tenemos:

Desplazamiento = (30 + 1/5) cm

Tiempo = (2/3 horas)

Entonces la velocidad esta dada por:

$V = \frac{(30 + 1/5)mi}{2/3 h} = \frac{(151/5)mi}{2/3 h} = 45.3 mi/h$

Asi podemos concluir que la velocidad promedio es 45.3 millas por hora.

Find the perimeter of the figure. Round your answer to the nearest tenth.

zloy xaker [14]

Counting the straight sides gives you 23 units and using the distance formula on the bottom side gives you about 11.18 units. 23+11.18=34.18 and round that to the nearest tenth to get the answer of 34.2 units.

Find the equation of a line through (3, 1) and perpendicular to 10x + 3y = 5

Illusion [34]

Answer:

y = (3/10)x + 1/10

Step-by-step explanation:

The general structure of an equation in slope-intercept form is:

y = mx + b

In this form, "m" represents the slope and "b" represents the y-intercept. First, we need to rearrange the given equation to determine the slope of the original line.

10x + 3y = 5 <----- Original equation

3y = -10x + 5 <----- Subtract 10x from both sides

y = (-10/3)x + 5 <----- Divide both sides by 3

Now, we can tell that the slope of the original line is m = -10/3. The perpendicular line should have an opposite-signed, reciprocal slope to that of the original. Therefore, the new slope is m = 3/10.

We can find the value of "b" by plugging the new slope and values from the Point (3, 1) into slope-intercept form.

m = 3/10

x = 3

y = 1

y = mx + b <----- Slope-intercept form

1 = (3/10)(3) + b <----- Insert values

1 = 9/10 + b <----- Multiply 3/10 and 3

10/10 = 9/10 + b <----- Create common denominators

1/10 = b <----- Subtract 9/10 from both sides

Now that we know the values for "m" and "b", we can construct the equation of the perpendicular line.

y = (3/10)x + 1/10
