Which polynomial is in standard form?

Tamiku [17]

Answer:

D). $5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9$

Step-by-step explanation:

For better clarity let us re write the options

A). $2xy^3+3x^3y^4-4x^4y^5+9x^5y^6$

B). $8x^5-5y^4-2xy^5+x^2y$

C). $x^3y^2-3x^2y-9x^4y^3+11x$

D). $5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9$

To express polynomial with mixed variables in standard form, we begin by the highest coefficient of x to the smallest (we place high precedence on the coefficient x terms)

Para hacer 600 m de una obra, 30 obreros han trabajado 12 dias a razon de 10 horas diarias. ¿Cuantos dias necesitaran 36 obreros

Gwar [14]

Respuesta:

25 días

Explicación paso a paso:

Dado :

escenario 1

Área = 600 m

Número de días = 12

Número de trabajadores = 30

Tasa = 6

Escenario 2:

Área = 900 m

Número de días = n

Número de trabajadores = 36

Tasa = 6

Igualar los parámetros en cada escenario:

12 / n = 36/30 * 6/10 * 600/900

12 / n = 6/5 * 3/5 * 2/3

12 / n = 6/5 * 1/5 * 2/1

12 / n = 12/25

12 * 25 = 12n

300 = 12n

n = 300/12

n = 25 días

Answer:

5500 meters

Step-by-step explanation:

Meters = m

Kilometres = km

We use the general formula,

1 km = 1000 m

Then by using the general formula,

5.5 km = ? m

→ 5.5 km/1 km × 1000 m

→ 5.5 m × 1000 m

→ 5500 m

Hence, the solution is 5500 m.
