The factors of a number are all positive integers that divide evenly into the number. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, 40.

To add these distances, they must share the same unit so first you need to first convert the swim distance from meters (m) to kilometers (km) before adding it to the bike and run distances which are already in km. To convert 200 meters to kilometers, divide the distance by 1000 to get 0.2km then add the remaining distances:

total distance = swim + bike + run
total distance = 0.2km + 50.8km + 11.0km
total distance = 62km

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

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

9\( \sqrt{27} \) - 3\( \sqrt{3} \)
9\( \sqrt{9 \times 3} \) - 3\( \sqrt{3} \)
9\( \sqrt{3^2 \times 3} \) - 3\( \sqrt{3} \)
(9)(3)\( \sqrt{3} \) - 3\( \sqrt{3} \)
27\( \sqrt{3} \) - 3\( \sqrt{3} \)

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

If 77% of the town's 31,000 voters cast ballots the number of votes cast is:

(\( \frac{77}{100} \)) x 31,000 = \( \frac{2,387,000}{100} \) = 23,870

The mayor got 64% of the votes cast which is:

(\( \frac{64}{100} \)) x 23,870 = \( \frac{1,527,680}{100} \) = 15,277 votes.
