A prime number is an integer greater than 1 that has no factors other than 1 and itself. Examples of prime numbers include 2, 3, 5, 7, and 11.
If the ratio of home fans to visiting fans in a crowd is 5:1 and all 33,000 seats in a stadium are filled, how many home fans are in attendance?
| 29,250 | |
| 27,500 | |
| 34,400 | |
| 25,000 |
A ratio of 5:1 means that there are 5 home fans for every one visiting fan. So, of every 6 fans, 5 are home fans and \( \frac{5}{6} \) of every fan in the stadium is a home fan:
33,000 fans x \( \frac{5}{6} \) = \( \frac{165000}{6} \) = 27,500 fans.
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 25% off." If Charlie buys two shirts, each with a regular price of $17, how much money will he save?
| $5.95 | |
| $4.25 | |
| $3.40 | |
| $5.10 |
By buying two shirts, Charlie will save $17 x \( \frac{25}{100} \) = \( \frac{$17 x 25}{100} \) = \( \frac{$425}{100} \) = $4.25 on the second shirt.
What is the next number in this sequence: 1, 7, 13, 19, 25, __________ ?
| 24 | |
| 23 | |
| 31 | |
| 34 |
The equation for this sequence is:
an = an-1 + 6
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 + 6
a6 = 25 + 6
a6 = 31
A triathlon course includes a 500m swim, a 30.8km bike ride, and a 12.9km run. What is the total length of the race course?
| 37.5km | |
| 44.2km | |
| 35.6km | |
| 50.5km |
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 + 30.8km + 12.9km
total distance = 44.2km
