Answer:

The volume of the pyramid is 130\frac{2}{3}\ units^{3}

Step-by-step explanation:

we know that

The volume of the pyramid is equal to

V=\frac{1}{3}BH

where

B is the area of the base

H is the height of the pyramid

<em>Find the area of the base B</em>

In this problem we have a square base

B=7^{2} =49\ units^{2}

we have

H=8\ units

substitute

V=\frac{1}{3}(49)(8)=\frac{392}{3}\ units^{3}

Convert to mixed number

\frac{392}{3}=\frac{390}{3}+\frac{2}{3}=130\frac{2}{3}\ units^{3}

In any given week, salesman A earns $65 per sale, so his paycheck amounts to p_A(s)=65s (where 0\le s\le20).

Salesman B earns $40 per sale, with a weekly salary of $300, so in any given week this salesman earns p_B(s)=45s+300.

Salesman C earns a flat rate of $900 per week regardless of the number of sales, so his weekly pay is p_C(s)=900.

Justo ayer fue el cumpleaños de Mauricio. Si a la edad e Mauricio, le sumo 13, al resultado le resto 10, luego al nuevo resultad
bezimeni [28]

Answer:

Mauricio nació en el año 2000.

Step-by-step explanation:

Supóngase que el cumpleaños se celebra en el año 2020, si x es la edad actual de Mauricio, entonces la expresión matemática que traduce el enunciado del problema es:

\frac{(x+13)-10}{23} +20 = 21

Ahora, se desarrolla y se simplifica la ecuación:

\frac{x+3}{23}+20 = 21

\frac{x+3}{23} = 1

Se despeja x:

x +3 = 23

x = 20

Mauricio tiene 20 años.

Ahora, el año de nacimiento de Mauricio es la sustracción de la edad de Mauricio del año actual:

y = 2020-20

y = 2000

Mauricio nació en el año 2000.
