Answer:

Al comienzo Juana tiene 28 libras de azúcar.

Ella hace 6 paquetes de 2.5kg cada paquete.

Entonces, entre los 6 paquetes, hay:

6*2.5kg = 15kg de azúcar.

Ahora el problema es que tenemos dos unidades distintas, kilogramos y libras.

Aca podemos usar la relación:

1k = 2.2lb.

Entonces 15kg de azúcar son 15 veces 2.2 libras:

15kg = 15*2.2lb = 33lb.

Esto nos da mas de lo que hay originalmente en el costal.

Ahora si lo pensamos como:

Solo vendió 5 paquetes de 2.5kg, entonces el sobrante queda en el costal inicial:

5*2.5kg = 12.5kg

De vuelta, 1kg = 2.2lb

12.5kg = 12.5*2.2lb = 27.5lb

En este caso hay un sobrante de:

28lb - 27.5lb = 0.5lb

Examine the diagram, where BD is tangent to circle M at point D, and BA is secant to the same circle at points E and A.
Stella [2.4K]

Answer:

19 = x

Step-by-step explanation:

The square of the tangent segment = The product of (whole secant segment) (the outside part of the secant segment)

BD²= (BA)(BE)        

8² = (4 + x - 7) (4)             BA = BE + EB

8² = (x - 3)(4)

64 = 4x - 12

64 + 12 = 4x

76 = 4x

19 = x
