Answer:

Marcia is 47 inches tall.

Step-by-step explanation:

Let's solve this step by step and try to visualize the situation.

• Carl: 73 inches tall

The second part of the question states that Carl's heigh is twenty-one inches less than two times Marcia's height. Add 73 + 21 to equal 94. Since Carl is 21 inches less that means that Maria is 21 inches more ( so that's why I added instead of subtracting) because we are trying to find Maria's equation.

Let x be Marcia's height

2x = 94

• The question staes that 73 is 21 inches less than two times Marcia's height which means that the equation 2x = 94 applies because 73 + 21 = 94

After simplifying the equation, we can get the answer that Marcia is 47 inches tall.

Answer:

Step-by-step explanation:

Givens

Carl  = 73

Marcia = 2x - 21 = 73

Solution

2x - 21 = 73                           Add 21 to both sides.

2x = 73 + 21                          Combine

2x = 94                                 Divide by 2

2x/2 = 94/2

x = 47

Tanya tiene un jardin con un foso alrededor. El jaidim el un rectangulo de 2 1/2m de largo y 2m de ancho. El jardin y el foso ju
professor190 [17]

Answer:

El área del foso es 5.5 m²

Step-by-step explanation:

Hola!

Por favor, mira el esquema adjunto para una descripción del problema.

Viendo la figura, podemos deducir que el área del foso será igual al área del rectángulo formado por el jardín y el foso menos el área del jardín.

Área del foso = área del foso y jardín - área del jardín.

El área de un rectángulo se calcula multiplicando la longitud de la base por la altura:

Área del jardín = 2.5 m · 2 m = 5 m²

Área del rectángulo jardín - foso = 3.5 m · 3 m = 10.5 m²

Área del foso = 10.5 m² - 5 m² = 5.5 m²

El área del foso es 5.5 m²

aleksley [76]

Answer:

"34,814" is the correct solution.

Step-by-step explanation:

The given values are:

Intercept coefficient,

\beta_0 = 23,859

Production coefficient,

\beta_1 = 3.13

Units sold,

x = 3,500

Now,

The total cost will be:

⇒  \bar{y}=\beta_0+\beta_1 x

On substituting the estimated values, we get

⇒     =23,859+3.13\times 3,500

⇒     =23,859+10,955

⇒     =34,814
