How many 6-passenger vans will it take to drive all 94 members of the football team to an away game?
| 5 vans | |
| 3 vans | |
| 6 vans | |
| 16 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{94}{6} \) = 15\(\frac{2}{3}\)
So, it will take 15 full vans and one partially full van to transport the entire team making a total of 16 vans.
If there were a total of 400 raffle tickets sold and you bought 28 tickets, what's the probability that you'll win the raffle?
| 4% | |
| 7% | |
| 11% | |
| 3% |
You have 28 out of the total of 400 raffle tickets sold so you have a (\( \frac{28}{400} \)) x 100 = \( \frac{28 \times 100}{400} \) = \( \frac{2800}{400} \) = 7% chance to win the raffle.
What is -3y2 - 3y2?
| -6y2 | |
| -6y-2 | |
| 6y-2 | |
| 6y2 |
To add or subtract terms with exponents, both the base and the exponent must be the same. In this case they are so subtract the coefficients and retain the base and exponent:
-3y2 - 3y2
(-3 - 3)y2
-6y2
A triathlon course includes a 500m swim, a 50.5km bike ride, and a 7.300000000000001km run. What is the total length of the race course?
| 51.2km | |
| 55km | |
| 58.3km | |
| 43.2km |
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 + 50.5km + 7.300000000000001km
total distance = 58.3km
If a car travels 220 miles in 4 hours, what is the average speed?
| 65 mph | |
| 50 mph | |
| 55 mph | |
| 30 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)
