A triathlon course includes a 500m swim, a 20.3km bike ride, and a 10.4km run. What is the total length of the race course?
| 52.7km | |
| 29km | |
| 31.2km | |
| 41.7km |
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 500 meters to kilometers, divide the distance by 1000 to get 0.5km then add the remaining distances:
total distance = swim + bike + run
total distance = 0.5km + 20.3km + 10.4km
total distance = 31.2km
What is the next number in this sequence: 1, 3, 7, 13, 21, __________ ?
| 31 | |
| 22 | |
| 30 | |
| 36 |
The equation for this sequence is:
an = an-1 + 2(n - 1)
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 2(6 - 1)
a6 = 21 + 2(5)
a6 = 31
A tiger in a zoo has consumed 45 pounds of food in 5 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 99 pounds?
| 5 | |
| 6 | |
| 2 | |
| 8 |
If the tiger has consumed 45 pounds of food in 5 days that's \( \frac{45}{5} \) = 9 pounds of food per day. The tiger needs to consume 99 - 45 = 54 more pounds of food to reach 99 pounds total. At 9 pounds of food per day that's \( \frac{54}{9} \) = 6 more days.
If there were a total of 100 raffle tickets sold and you bought 7 tickets, what's the probability that you'll win the raffle?
| 6% | |
| 7% | |
| 19% | |
| 16% |
You have 7 out of the total of 100 raffle tickets sold so you have a (\( \frac{7}{100} \)) x 100 = \( \frac{7 \times 100}{100} \) = \( \frac{700}{100} \) = 7% chance to win the raffle.
