Justine answered 69 questions correctly on a 150 question test
MArishka [77]

Answer:

I am assuming you are asking for what percent correct she got. She got 46% correct.

Step-by-step explanation:

You divide the answers correct by the total questions. She got 69 out of 150, so dividing that is .46

To turn a decimal into a percentage, just move the decimal two places to the right, thus getting 46 %

If I assumed what you were asking incorrectly, let me know and I'll be happy to help!

Katarina [22]

Answer:

$6390 se destinaron a los fondos de reserva, $7668 se destinaron a los fondos de provisión y $8520 se destinaron a los fondos de operaciones.

Step-by-step explanation:

Dado que una cooperativa de agricultores obtuvo en el año 2020 una utilidad de $42,600, de cuya suma destino el 15% para fondos de reserva, 18% para fondos de provisión y el 20% para fondos de operaciones, para calcular cada una de la suma​s se debe realizar el siguiente cálculo:

100 = 42,600

15 = X

42600 x 15 / 100 = 6390

100 = 42,600

18 = X

42600 x 18 / 100 = 7668

100 = 42,600

20 = X

42600 x 20 / 100 = 8520

Por lo tanto, $6390 se destinaron a los fondos de reserva, $7668 se destinaron a los fondos de provisión y $8520 se destinaron a los fondos de operaciones.
