Answer: 5,000cm³
Well, 1 mL (milliliter) is equivalent to 1 cubic centimeter (cm³). There is 1,000 mL in a liter, so there are 5,000 mL in 5 liters and therefore 5 liters equals 5,000 cm³.

Your problem is:
$35.00 is what percentage of $437.50?

In this case, the whole is $437.50.
The part is $35.00.

35/437.5 * 100 = 8%

Steve will roll a number cube, numbered 1-6, twice. What is the probability
Leni [432]

Answer:

25%

Step-by-step explanation:

First we calculate the probability of rolling a number greater than 3, that is, it can be 4, 5 or 6.

The probability of each number is 1/6, so:

P1 = (1/6) + (1/6) + (1/6) = 3/6 = 1/2

Then, we calculate the probability of rolling a prime number, that is, 2, 3 or 5.

As we have again 3 numbers, the probability P2 will also be 1/2

Then, the final probability is the product of both P1 and P2:

P = P1 * P2 = (1/2) * (1/2) = 1/4 = 25%
