Answer:

A) Se requiere una tabla con una longitud de 2.213 varas para fabricar la mesa.

B) El lote de José tiene una extensión de 536.481 varas cuadradas.  

Step-by-step explanation:

A) La vara es una unidad de longitud equivalente a 0.836 metros. También sabemos que un cuadrado es una figura geométrica con cuatro lados de igual longitud y cuatro ángulos rectos, de modo que la longitud y ancho de la mesa es igual. Entonces, el largo de la tabla, esto es, la superficie superior de la mesa, tiene una medida de 1.85 metros.

A continuación, realizamos la regla de tres para determinar su equivalente en varas:

x = 1.85\,m\times\frac{1\,vara}{0.836\,m}

x = 2.213\,varas

Se requiere una tabla con una longitud de 2.213 varas para fabricar la mesa.

B) La vara es una unidad de longitud equivalente a 0.836 metros. Una vara cuadrada es una unidad de área y es igual a:

r = (0.836\,m)\cdot (0.836\,m)

r = 0.699\,m^{2}

De manera semejante, tenemos que el área del lote de Jose es un rectángulo y que se calcula como sigue en metros cuadrados:

A = l\cdot w (Eq. 1)

Donde:

A - Área del lote de José, medido en metros cuadrados.

l - Largo del lote de José, medido en metros cuadrados.

w - Ancho del lote de José, medido en metros cuadrados.

Si l = 25\,m y w = 15\,m, entonces el área del lote es:

A = (25\,m)\cdot (15\,m)

A = 375\,m^{2}

Por último, hallamos el área en varas cuadradas mediante la siguiente regla de tres:

x = 375\,m^{2}\times \frac{1\,vara}{0.699\,m^{2}}

x = 536.481\,varas^{2}

El lote de José tiene una extensión de 536.481 varas cuadradas.

Theresa Corporation, which manufactures baskets, is developing direct labor standards. The basic direct labor rate is $18.00 per
Stella [2.4K]

Answer:

$24.52

Step-by-step explanation:

The basic direct labor rate = $18.00 per hour.

Payroll taxes are 14% of the basic direct labor rate

So, payroll Tax = 14% of 18

So, payroll Tax = \frac{14}{100} \times 18 = 2.52

Fringe benefits such as vacation and health care insurance, are $4.00 per hour.

So, standard rate per direct labor hour= $18.00 +$2.52+$4.00

Standard rate per direct labor hour= $24.52

Hence the standard rate per direct labor hour is $24.52
