"What is the probability of drawing a jack or queen from a standard deck of cards?"

Natasha2012 [34]

Well, there are 52 cards in a deck, with 4 suits. there is a Jack and queen per suit, so that is a total of 8 jacks and queens in the deck. that probability looks like 8:52 as a ratio, or 2:13 simplified. so, you are likely to draw a Jack or queen 8 out of 52 times, or 2 out of 13 times

Las llantas de un automóvil pequeño tiene una medida de 14 pulgadas de diámetro.Realiza la gráfica de una de las llantas colocan

LiRa [457]

Answer:

Invitamos cordial a revisar la imagen adjunta abajo para mayor detalle sobre la gráfica de las llantas.

La forma general de la circunferencia de la llanta está representada por $x^{2}+y^{2}-49 = 0$ .

Step-by-step explanation:

A continuación, anexamos una representación de las llantas del automóvil como una circunferencia centrada en el origen y con un diámetro de 14 pulgadas, es decir, un radio de 7 pulgadas.

La ecuación estándar de la circunferencia centrada en un punto dado y con un radio determinado está definida por:

$(x-h)^{2}+(y-k)^{2} =r^{2}$ (1)

Donde:

$h$ , $k$ - Coordenadas del centro de la circunferencia, medidas en pulgadas.

$r$ - Radio de la circunferencia, medido en pulgadas.

Si conocemos que $h = 0\,in$ , $k = 0\,in$ y $r = 7\,in$ , entonces la ecuación estándar que representa a la circunferencia de la llanta es:

$x^{2}+y^{2} = 49$

Ahora, la ecuación general de la circunferencia centrada en el origen satisface la siguiente expresión:

$A\cdot x^{2}+A\cdot y^{2}+B = 0$ (2)

Donde $A$ , $B$ son los coeficientes de forma de la circunferencia.

Entonces, la forma general de la circunferencia de la llanta está representada por la siguiente expresión:

$x^{2}+y^{2}-49 = 0$

A bike is bought for $1200 and sold 10 months later for $940.

Stolb23 [73]

Value

Depreciation is defined as the reduction in value of an asset over time. In this case, value reduction is due to wear and tear of an equipment (bicycle).

a. The depreciation value would simply be the difference in initial and salvage value divided by time in years.

Depreciation = (Initial value – Salvage value) / Number of years

b. Substituting the given values into the equation where:

Initial value = $1200

Salvage value = $940

Number of years = 10 months = 10/12 years

Calculating:

Depreciation = ($1200 - $940) / (10/12 years)

Depreciation = $312 / year

<span>Depreciation = $26 / month</span>

the length of a retangle is 4 inches greater than the width. the perimeter of the retangle is 24 inches. What are the dimensions

Marianna [84]

$24 = 2w + 2(w+4) \\24 = 2w + 2w + 8 \\24 = 4w + 8 \\24 - 8 = 4w \\16 = 4w \\\tfrac{16}{4} = w 4 = w$

The width is 4 inches, and length is 8 inches.

!Help !

svetoff [14.1K]

Answer:

50 minutes

Step-by-step explanation:

she spent 1 hr and 30 minutes on homework

she spends 2/3 of an hour on the phone = 40 minutes

1 hr 30 min + 40 minutes = 2 hrs and 10 min

so she had 50 minutes to kill before bedtime since she goes to sleep 3 hrs after dinner

2hr 10 min + 50 min = 3 hrs.
