guapka [62]

Given:

a. 35% of 150 g

b. 113% of $55

To find:

The correct values for the given blanks.

Solution:

a. 35% of 150 g

Here, the percent part is 35% and percent whole is 100%.

35% of 150 g is:

\dfrac{35}{100}\times 150=52.5

So, the number part is 52.5 g and the whole number is 150 g.

Therefore, the percent part is 35%, number part is 52.5 g and the whole number is 150 g.

b. 113% of $55 g

Here, the percent part is 113% and percent whole is 100%.

113% of $55 is:

\dfrac{113}{100}\times 55=62.15

So, the number part is $62.15 and the whole number is $55.

Therefore, the percent part is 113%, number part is $62.15 and the whole number is $55.

LenKa [72]

Responder:

$ 1360

Explicación paso a paso:

La pregunta está incompleta. Aquí está la pregunta completa.

Un inversor aplica R $ 1,000.00 a votos simples de 3% al año o más. Determinar o valor recibido después de 12 años:

Antes de determinar el valor recibido después de un año, necesitamos encontrar el interés simple sobre el dinero después de 12 años.

Interés simple = Principal * tasa * tiempo / 100

Principal dado = $ 1,000 (cantidad invertida)

Tasa = 3%

Tiempo = 1 año

SI = 1000 * 3 * 12/100

SI = 36000/100

SI = $ 360

Cantidad después de 12 años = Principal + Interés

Cantidad = $ 1000 + $ 360

Cantidad = $ 1360
