7 0

Answer:

C. \frac{9}{14} , 9:14 , or 9 to 14

Step-by-step explanation:

With there being 9 teachers and 5 aides, the total number of adults is 14, leaving a fraction of \frac{9}{14} , 9 teachers and 14 adults. Checking to simplify, there are no shared values by 9 and 14, so it is in it's simplest form.

Arlecino [84]
For this case, the total amount invested is:
 investment = 3500 + 1000 = 4500
 We must take out the percentage of what X invested.
 X investment = (3500/4500) * 100 = 77.78%.
 Therefore, X gets 77.78% of the profits:
 X profit = 0.7778 * 3000 = 2333.33 $
 answer
 if the profits are distributed in proportion to the amount invested X receives 2333.33 $

enot [183]

Answer:

La altura del globo con respecto al suelo es 449,6 metros.

Step-by-step explanation:

La afirmación está incompleta. El enunciado completo es: "Un globo vuela entre dos ciudades A y B, que distan entre sí 1.500 m. Los tripulantes del globo ven la ciudad A con un ángulo de depresión de 27°, mientras que para ver la ciudad B es de 36°. ¿Cuál es la altura aproximada del globo con respecto al suelo?

El diagrama geométrico de la situación se encuentra descrita en el archivo adjunto. La altura aproximada del globo puede obtenerse con ayuda de las funciones trigonométricas, en este caso, se recomienda utilizar la función tangente de los ángulos de depresión:

Ciudad A

\tan 27^{\circ} = \frac{h}{1500\,m-x}

0,510 = \frac{h}{1500\,m-x}

Ciudad B

\tan 36^{\circ} = \frac{h}{x}

0,727 = \frac{h}{x}

Donde h y x son la altura con respecto al suelo y la distancia horizontal con respecto a la ciudad A.

A continuación, se elimina la altura de ambas ecuaciones por igualación y se determina la distancia horizontal del globo con respecto a la ciudad A:

0,727\cdot x = 0,510\cdot (1500\,m-x)

1,237\cdot x = 765\,m

x = 618,432\,m

Finalmente, la altura del globo con respecto al suelo es:

h = 0,727\cdot x

h = 0,727\cdot (618,432\,m)

h = 449,600\,m

La altura del globo con respecto al suelo es 449,6 metros.

HELP NOW!!! 20 POINTS AND URGENTLY NEEDED!!!!!!!!!!!!!!
Lunna [17]

So basically here is the answer mate!

2x  +  7y  =  3-------------------------(substitute x's value here, i.e., x = -4y)

2( -4y )  +  7y  =  3

-8y  +  7y  =  3

-1y  =  3

y  =  -3------------------------(  1  )

Since x  =  -4y

             =  -4 (  -3  )  --------------------------( since we found the value of y)

             =  12

Here is the answer for  x  = 12  ,  y  =  -3

Mark my anwer as the brainliest please !  :)
