Answer:

\frac{-y-1}{8}

Step-by-step explanation:

1/2y - 5/8y = 4/8y - 5/8y = -1/8y

3/4 - 7/8 = 6/8 - 7/8 = -1/8

-1/8y - 1/8 =

The following table provides information about the median income in four states in
photoshop1234 [79]

Answer:

$68,213

Step-by-step explanation:

The median is the middle value number.

So you need median for Virginia.

First lets see how index and income are connected.

To do this divide the income by the index to see if you have a constant value you can use.

535.434783 = Arkansas

535.381944 = Alabama

535.58 = Arizona

535.669236 = Alaska

535 is constant in all of these.

Let's multiply the index by 535.

127.2*535 =68212.5

For median income, you need a whole number so lets round up.

68213

So Virginia would have a median income rate of $68,213

Un observador se encuentra en un faro al pie de un acantilado a 687m sobre el nivel del mar, desde este punto observa un barco c
maks197457 [2]

La distancia entre el barco y la base del acantilado es 291.61 metros.

<h3>¿Como calcular la distancia?</h3>

Podemos pensar en esta situacion como en un triangulo rectangulo. Uno de los catetos mide 687 metros, que es la altura del acantilado.

Y conocemos el angulo al que ese cateto es adjacente, que mide 23 grados.

La distancia entre la base del acantilado y el barco será el otro cateto del triangulo rectangulo.

Entonces podemos usar la relación:

tan(a) = (cateto opuesto)/(cateto adjacente)

Reemplazando lo que sabemos:

tan(23°) = D/687m

tan(23°)*687m = D = 291.61m

La distancia entre el barco y la base del acantilado es 291.61 metros.
