In order for the parallelogram to be a rhombus x = ?
Zina [86]

Answer: x= 207.8873386

Step-by-step explanation:

expecting both 2x-15 and 3x are angles in radiant, let's draw a rhombus ABCD

∠ABC = 2x-15

∠ BCD = 3x

∠ABC + < BCD= π ( 180° in radiant)

2x - 15 + 3x = π

5x - 15 = π

x - 3 = 1/5π

= 3.628318531 = 207.8873386

2x−15°+3x=180

5x-15°=180

5x=195°

x=39°

The manager of a 100-unit apartment complex knows from experience that all units will be occupied if the rent is $800 per month.
Ede4ka [16]
800 * 100 = 80000
810 * 99 = 80190
900 * 90 = 81000
1000 * 80 = 80000
(800 + 10n) (100-1n)
=(800 +10(11)) (100 - 11)<span> (910)(89) = 80990</span>

Problemas de razonamiento división de números decimales. Ayer Susana se fue de viaje a visitar a unos familiares. Recorrió 135,7
schepotkina [342]

Usando las relaciones entre velocidad, distancia y tiempo, se encuentra que ella condujo a una velocidad media de 90,5 km/h.

--------------------------

La <u>velocidad </u><u>es la distancia dividida por el tiempo</u>, por lo que:

v = \frac{d}{t}

  • Total de 135,75 km, o sea, d = 135,75
  • Llego en 1,5 horas, o sea, t = 1,5

La velocidad es:

v = \frac{d}{t} = \frac{135,75}{1,5}

División de decimales, o sea, seguimos multiplicando los números por 10 hasta que ninguno sea decimal:

v = \frac{135,75}{1,5} = \frac{1357,5}{15} = \frac{13575}{150} = 90,5

Ella condujo a una velocidad media de 90,5 km/h.
