There is a bag full of red, yellow, and green marbles. There are 3 red, 2 yellow, and 7 green. What is the probability of gettin
statuscvo [17]

Answer:

1/6 and 16.67

Step-by-step explanation:

Add all the marbles, you get 12.

There's 2 out of 12 yellow marbles so you get 2/12

2/12 simplified to 1/6

So 1/6 is the probability as a fraction

Now to get the percentage just divide 100 by 6.

100/6 equals 16.67

Since it's 1/6 we multiply that by one

16.67 times 1 equals 16.67

Lauren in making 15 liters of mimosas for a brunch banquet. Orange juice costs her $1.50 per liter and champagne costs her $12 p
PSYCHO15rus [73]

Answer:

  • 10 liters of orange juice
  • 5 liters of champagne

Step-by-step explanation:

Let c represent the number of liters of champagne Lauren uses. Then (15-c) will be the number of liters of orange juice. The total cost of the mix will be ...

  12c +1.50(15-c) = 5.00(15)

  10.5c = 52.50 . . . . . subtract 22.50, simplify

  52.50/10.5 = c = 5 . . . . divide by the coefficient of c

Then the amount of orange juice is ...

  15 -c = 15 -5 = 10 . . . . liters

Lauren should use 5 liters of champagne and 10 liters of orange juice.
