To find the sum and difference of the two rocks, you would do:

\frac{3}{8} + \frac{2}{8} =  \frac{3+2}{8} =\boxed{\bf{\frac{5}{8}}}\\\\\\ \frac{3}{8} - \frac{2}{8} =  \frac{3-2}{8} =\boxed{\bf{\frac{1}{8}}}

Answer:

decrease by 50%

Step-by-step explanation:

\frac{0.4x}{0.8y} =\frac{x}{2y}      

Decreased by 60% = (100%-60%)x = 0.4x.

Decreased by 20% = (100%-20%)x = 0.8x.

\frac{x}{y} initial fraction, and we can see that denominator will increase 2 times, so fraction will decrease 2 times, or decrease by 50%.

A gym initially has 5000 members. Each year, the gym loses 10% of its current members and gains 100 new members. Which recursive
Elis [28]

Answer:

An = A0 + 100 * n - (An-1) * 0.10

Step-by-step explanation:

Tenemos una regla recursiva para una secuencia es una fórmula que nos dice cómo avanzar de un término a otro en una secuencia. Por lo tanto debemos buscar a An.

Hay un valor inicial que es 5000, una ganancia y una perdida de clientes, que podemos representar así:

An = 5000 + Ganancia - Perdida

Inicial = A0 = 5000

Ganancia = 100, pero cómo sucede cada año, sería: 100 * n

Perdida = 10% de los miembros actuales, si al principio son 5000 por lo tanto A0 * 0.10, pero en este primer caso es que es A0, pero en general serían An-1

reemplazando:

An = A0 + 100 * n - (An-1) * 0.10
