Volume of one room = Length × Width × Height

Volume of one room = 14 ft × 11 ft × 8 ft

Volume of one room = 1232 ft³

Total volume of water flooding the area = Volume of one room × Number of rooms

Total volume of water flooding the area = 1232 ft³ × 3

Total volume of water flooding the area = 3696 ft³

Volume of one room = 14 ft × 11 ft × 8 ft

Volume of one room = 1232 ft³

Total volume of water flooding the area = Volume of one room × Number of rooms

Total volume of water flooding the area = 1232 ft³ × 3

Total volume of water flooding the area = 3696 ft³

Volume = Weight / Weight per cubic inch

Volume = 91 pounds / 0.28 pounds per cubic inch

Volume 325 cubic inches

Length = Volume / Cross-sectional area

Length = 325 cubic inches / 5 square inches

Length 65 inches

Volume = 91 pounds / 0.28 pounds per cubic inch

Volume 325 cubic inches

Length = Volume / Cross-sectional area

Length = 325 cubic inches / 5 square inches

Length 65 inches

What is the probability that you flip a coin and get a heads up, draw a card from a standard poker deck and get an ace, and roll 2 dice and get a sum of either 7 or 11? **Weegy:** For the coin, the probability is 50%. 5% chance for the card desk and the dice, 16% chance for the dice. (More)

Solution:

1. Flipping a coin and getting heads:

Assuming the coin is fair (unbiased), the probability of getting heads is 1/2.

2. Drawing an ace from a standard poker deck:

In a standard deck of 52 cards, there are 4 aces. So, the probability of drawing an ace is 4/52, which simplifies to 1/13.

3. Rolling 2 dice and getting a sum of either 7 or 11:

To get a sum of 7, there are 6 possible combinations of dice rolls: (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), and (6, 1). To get a sum of 11, there are 2 possible combinations: (5, 6) and (6, 5).

The total number of possible outcomes when rolling 2 dice is 6 * 6 = 36.

So, the probability of getting a sum of 7 is 6/36, which simplifies to 1/6.

The probability of getting a sum of 11 is 2/36, which simplifies to 1/18.

Now, let's calculate the overall probability by multiplying the individual probabilities:

Probability = Probability of heads * Probability of drawing an ace * Probability of getting a sum of 7 or 11

Probability = (1/2) * (1/13) * (1/6 + 1/18)

Probability = (1/2) * (1/13) * (4/18)

Probability = (1/2) * (1/13) * (2/9)

Probability = 1/117

So, the probability of flipping a coin and getting heads, drawing an ace from a standard poker deck, and rolling 2 dice and getting a sum of either 7 or 11 is 1/117 or approximately 0.0085 (rounded to four decimal places).

A portion of Karen's backyard is shaped like a triangle. With a base of 20 yards and a height of 13 yards. 130 square yards of sod will she need to cover this section.

Solution

A = 1/2 * 20 * 13

A = 1/2 * 260

A = 130 square yards

Solution

A = 1/2 * 20 * 13

A = 1/2 * 260

A = 130 square yards

Total taxable sales = Sales tax paid / Sales tax rate

Total taxable sales = $3575 / 0.065

3. Calculate the total taxable sales: Using a calculator, we can divide $3575 by 0.065 to find the total taxable sales.

Total taxable sales = $55,000

Therefore, the total taxable sales for May were $55,000.

Total taxable sales = $3575 / 0.065
