Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:

vans = \( \frac{60}{11} \) = 5\(\frac{5}{11}\)

So, it will take 5 full vans and one partially full van to transport the entire team making a total of 6 vans.

You have 13 out of the total of 450 raffle tickets sold so you have a (\( \frac{13}{450} \)) x 100 = \( \frac{13 \times 100}{450} \) = \( \frac{1300}{450} \) = 3% chance to win the raffle.

To subtract these radicals together their radicands must be the same:

4\( \sqrt{80} \) - 9\( \sqrt{5} \)
4\( \sqrt{16 \times 5} \) - 9\( \sqrt{5} \)
4\( \sqrt{4^2 \times 5} \) - 9\( \sqrt{5} \)
(4)(4)\( \sqrt{5} \) - 9\( \sqrt{5} \)
16\( \sqrt{5} \) - 9\( \sqrt{5} \)

Now that the radicands are identical, you can subtract them:

To fill a 6 gallon tank exactly halfway you'll need 3 gallons of fuel. Each fuel can holds 1\(\frac{1}{2}\) gallons so:

cans = \( \frac{3 \text{ gallons}}{1\frac{1}{2} \text{ gallons}} \) = 2

The ratio of football cards to baseball cards is 3:2 and the ratio of baseball cards to basketball cards is 3:1. To solve this problem, we need the baseball card side of each ratio to be equal so we need to rewrite the ratios in terms of a common number of baseball cards. (Think of this like finding the common denominator when adding fractions.) The ratio of football to baseball cards can also be written as 9:6 and the ratio of baseball cards to basketball cards as 6:2. So, the ratio of football cards to basketball cards is football:baseball, baseball:basketball or 9:6, 6:2 which reduces to 9:2.
