If the ratio of home fans to visiting fans in a crowd is 5:1 and all 46,000 seats in a stadium are filled, how many home fans are in attendance?
| 38,333 | |
| 23,333 | |
| 40,000 | |
| 38,400 |
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:
46,000 fans x \( \frac{5}{6} \) = \( \frac{230000}{6} \) = 38,333 fans.
If a car travels 420 miles in 7 hours, what is the average speed?
| 45 mph | |
| 60 mph | |
| 25 mph | |
| 15 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)Which of these numbers is a factor of 32?
| 32 | |
| 12 | |
| 29 | |
| 22 |
The factors of a number are all positive integers that divide evenly into the number. The factors of 32 are 1, 2, 4, 8, 16, 32.
17 members of a bridal party need transported to a wedding reception but there are only 4 4-passenger taxis available to take them. How many will need to find other transportation?
| 8 | |
| 1 | |
| 9 | |
| 3 |
There are 4 4-passenger taxis available so that's 4 x 4 = 16 total seats. There are 17 people needing transportation leaving 17 - 16 = 1 who will have to find other transportation.
What is the next number in this sequence: 1, 3, 7, 13, 21, __________ ?
| 39 | |
| 24 | |
| 30 | |
| 31 |
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
