Vickie made a recipe for 144 fluid ounces of scented candle wax. How many 1 cup candle molds can she fill with the recipe?
jeka57 [31]
There are 8 fluid ounces in 1 cup.  You can solve this problem using these proportions:

\frac{8}{1} = \frac{144}{x}

It states that there are 8 fluid ounces in every 1 cup and 144 fluid ounces in every <em>x </em>cups.  We have to solve for <em>x </em>using cross-multiplication:

8x = 144 \\ x=18

Vickie can fill 18 1 cup candle molds with 144 fluid ounces of scented candle wax.

If you roll a number cube two times, what is the probability of rolling an even on the first roll and a four on the second roll?
Bad White [126]

Answer:

1/12

Step-by-step explanation:

Probability is a ratio derived as the number of possible outcomes divided by the total outcome.

On a number cube, the even sides are 2, 4 and 6. This means that the possible outcome for rolling an even is 3 while the total outcome is 6. Hence the probability of rolling an even P(E)

= 3/6

The probability of rolling a 4  P(4)

= 1/6 (4 appears on one side)

Hence  the probability of rolling an even on the first roll and a four on the second roll

P(En4) = 3/6 * 1/6

= 3/36

= 1/12
