A family has two cars. The first car has a fuel efficiency of 25 miles per gallon of gas and the second has a fuel efficiency of
Oxana [17]

first car is x

second car is y

25x+30y=1550

x+y=55

Multiply the second equation by -25 for elimination method to cancel out x

-25x-25y=-1375

Add the two equations

5y=175

y=35

Plug this value into the second equation

x+35=55

x=20

Final answers:

First car=20 gallons

Second car=35 gallons

If f (x) = 2x +1 and g(x) = x^2 + 2x + 1, find f (g(x)).
Morgarella [4.7K]

Answer:

2x² + 4x + 3

Step-by-step explanation:

Given:

f (x) = 2x +1

g(x) = x² + 2x + 1

to find f(g(x)), simply take the x-terms in f(x) = 2x+1 and replace them with g(x) = x² + 2x + 1

Hence,

f(g(x))

= f(x² + 2x + 1)

= 2(x² + 2x + 1) + 1

= 2x² + 4x + 2 +1

= 2x² + 4x + 3

Answer:

The maximum revenue will be R=\$25,000 at price p=\$100.

Step-by-step explanation:

Given:

R=-2.5p^2+500p

Find the vertex of the parabola represented by given equation:

p_v=\dfrac{-b}{2a}=\dfrac{-500}{2\cdot (-2.5)}=\dfrac{500}{5}=100

When p=\$100, then

R=-2.5\cdot 100^2+500\cdot 100=-2.5\cdot 10,000+50,000=-25,000+50,000=25,000

The maximum revenue will be R=\$25,000 at price p=\$100.

De un total de 24 niñas 1/4 practican natación, 1/2 juega volibol y el resto no practica ningún deporte. ¿Cuántas niñas no pract
masya89 [10]

Answer:

6 niñas no practican ningún deporte.

Step-by-step explanation:

De un total de 24 niñas, \frac{1}{4} practican natación. Esto se expresa mediante la operación matemática:

\frac{1}{4} *24

Para multiplicar una fracción por un número entero, cualquier entero n puede ser escrito como la fracción \frac{n}{1}. Entonces en este caso:

\frac{1}{4} *24=\frac{1}{4} *\frac{24}{1}

Ahora se multiplican los denominadores para obtener el denominador final y se multiplican los numeradores para obtener el numerador final:

\frac{1}{4} *24=\frac{1}{4} *\frac{24}{1}=\frac{1*24}{4*1}=\frac{24}{4}

Finalmente, se reduce el resultado hasta llegar a la forma más simple. Para obtener un resultado simplificado, se divide el numerador por el denominador.  En este caso, para reducir la fracción \frac{24}{4}, se divide 24 por 4. El resultado obtenido es 6. Esto indica que de un total de 24 niñas, 6 practican natación.

Por otro lado, de un total de 24 niños, \frac{1}{2} juegan voleibol. Esto se expresa mediante la operación matemática:

\frac{1}{2} *24

Resolviendo de manera similar a lo previamente calculado, se obtiene:

\frac{1}{2} *24= 12

Esto indica que de un total de 24 niñas, 12 practican voleibol.

Por lo que 6 niñas practican natación y 12 voleibol, siento un total de 18 niñas las que practican algún deporte. Por lo que la cantidad de niñas que no practican ningún deporte se calcula mediante:

24 niñas - 18 niñas que practican algún deporte= 6 niñas

<u><em>6 niñas no practican ningún deporte.</em></u>
