The greatest common factor (GCF) is the greatest factor that divides two integers.
If there were a total of 100 raffle tickets sold and you bought 5 tickets, what's the probability that you'll win the raffle?
| 6% | |
| 17% | |
| 9% | |
| 5% |
You have 5 out of the total of 100 raffle tickets sold so you have a (\( \frac{5}{100} \)) x 100 = \( \frac{5 \times 100}{100} \) = \( \frac{500}{100} \) = 5% chance to win the raffle.
What is \( 8 \)\( \sqrt{12} \) + \( 6 \)\( \sqrt{3} \)
| 14\( \sqrt{36} \) | |
| 14\( \sqrt{12} \) | |
| 14\( \sqrt{3} \) | |
| 22\( \sqrt{3} \) |
To add these radicals together their radicands must be the same:
8\( \sqrt{12} \) + 6\( \sqrt{3} \)
8\( \sqrt{4 \times 3} \) + 6\( \sqrt{3} \)
8\( \sqrt{2^2 \times 3} \) + 6\( \sqrt{3} \)
(8)(2)\( \sqrt{3} \) + 6\( \sqrt{3} \)
16\( \sqrt{3} \) + 6\( \sqrt{3} \)
Now that the radicands are identical, you can add them together:
16\( \sqrt{3} \) + 6\( \sqrt{3} \)7 members of a bridal party need transported to a wedding reception but there are only 3 2-passenger taxis available to take them. How many will need to find other transportation?
| 5 | |
| 7 | |
| 8 | |
| 1 |
There are 3 2-passenger taxis available so that's 3 x 2 = 6 total seats. There are 7 people needing transportation leaving 7 - 6 = 1 who will have to find other transportation.
