Responde el siguiente problema de lógica: Al mirar el reloj, vemos que la manecilla de los minutos apunta a un número que casual

ANTONII [103]

Answer: 11:50

Step-by-step explanation:

Ok, la manecilla de los minutos apunta al numero X.

si la ora es Y, entonces Y + X = 12:00

podemos asumir que Y es 11:y

y es la cantidad de minutos despues de las 11, es un numero entre 0 y 59 (por que una hora solo puede tener 60 minutos)

Si la manecilla de los minutos apunta al numero 6 por ejemplo, entoces:

y = 11:30 y X = 6 min

X + y = 11:30 + 0:06 = 11:36

Así funciona.

la equacion es:

y = 5*X

y tambien queremos que:

X + y = 60min

reemplazo y por lo de la equacion de arriba:

X + y = X + 5*X = 6X = 60min

X = 10

Si la manecilla apunta al 10, tenemos que:

y = 11:50 y X = 10min

y + X = 11:50 + 0:10 = 12:00

Entonces podemos concluir que la hora es 11:50.

solong [7]

Answer:

See attached picture

Step-by-step explanation:

To graph a linear function like y=mx+b, find m and b. Here m = -1/2 and b= 2 for $y=-\frac{1}{2}x+2$ .

Start at (0,2) on the y-axis and plot a point. Then move from that point one unit down and over to the right 2. Plot the point and connect.

suppose you have a rectangle with a length 8 cm and width 3 cm. Now suppose the sides are doubled. Find the percent os increase

mr Goodwill [35]

The original perimeter is 22 cm.

If both sides are doubled, the length would be 16 cm and the width would be 6 cm.
The perimeter would be 44 cm.

22/44 is 50%.
