Un rectangulo tiene area de 15/40 cm cuadrados y sabemos que uno de sus lados mide 5/8 cuanto medira el otro lado
GaryK [48]

Queremos encontrar la medida de un lado de un rectangulo, dado que conocemos la longitud del otro lado y el area del rectangulo.

Veremos que el otro lado del rectangulo mide 3/5 cm

Sabemos que para un rectangulo de largo L y ancho W, el area esta dada por:

A = L*W

En este caso sabemos que el area es igual a (15/40) cm^2.

Y sabemos que uno de sus lados (digamos que es el ancho) mide (5/8) cm.

Entonces podemos reemplazar eso en la ecuación del area:

(15/40) cm^2 = L*(5/8) cm.

Ahora podemos resolver esto para L.

L = (15/40 cm^2)/(5/8 cm) = (15/40 cm^2)*(8/5 cm^-1)

L = 3/5 cm

El otro lado del rectangulo mide 3/5 cm

If a store sells 300 flat screen TVs and 30% of high definition, how many high definition TVs were sold?
Blababa [14]
90 Tv’s are high def! 300/100 = 3 (this is what 1% equals because there’s 100% total) so if we know 1% is 3 tv’s and 30% are high def, then we find out how many tv’s 30% is. so if 3 is 1% then 30 x 1= 30 then 30x3 = 90!

The arc length is the product of the radius and the angle in radians.
  s = rθ
  s = (7 in)(2π*25/60)
  s = 35π/6 in ≈ 18.33 in

In 25 minutes, the tip of the minute hand moves 35π/6 inches, about 18.33 inches.
