Kaylis [27]

Answer:

Queremos hacer un problema donde tengamos adición (a + b) y substracción ( a - b) de números con signo, de tal forma que el resultado final sea 9.

El caso más simple para este tipo de problemas es algo como:

"Vas a un mercado a comprar un par de productos, el producto A cuesta $A, y el producto B cuesta $B, si solo tenés un billete de $C, cuanto será el vuelto?"

Bueno, el vuelto va a ser la diferencia entre lo que vos entregáis, $C, y el costo total de los productos que compras ($A + $B)

Entonces el vuelto va a ser:

vuelto = $C - ($A + $B)

Y queremos que el resultado de este problema sea 9, entonces podemos escribir:

vuelto = $9 = $C - ($A + $B)

Ahora debemos encontrar los valores de las incógnitas.

Podemos simplemente definir dos de ellas y encontrar la tercera, por ejemplo si $C = $20 y $A = $2, entonces:

$9 = $20 - ($2 + $B)

$9 = $20 - $2 -$B

$9 = $18 - $B

$9 - $18 = -$B

-$9 = -$B

Entonces $B será = $9.

Y el problema podría escribirse como:

"Vas a un mercado a comprar un par de productos, el producto A cuesta $2, y el producto B cuesta $9, si solo tenés un billete de $20, cuanto será el vuelto?"

A standard interior staircase has steps each with a rise (height) of 21 cm and a run (horizontal depth) of 24 cm. Research sugge

Alisiya [41]

Answer:

The staircase would extends 1.20 m if the changes were made.

Step-by-step explanation:

Acording tho the statement the total heigth is 5.04 m, that is 504 cm, each steps rises 21 cm. with this information we can calculte how many steps are in the whole staircase:

$Number steps= \frac{Total heigth}{each step} \\Number steps= \frac{504}{21} = 24 steps$

To calculate how much the staircase will extend, whe have to multiply the horizontal depth times the number of steps.

using the run of 24 cm that gives us a lengt of 576 cm and if the changes were made the new length will be 696 cm.

So the staircase would extend an amount of (696 - 576), that is 120 cm, or 1.20 m, if the changes were made.
