How many 9-passenger vans will it take to drive all 31 members of the football team to an away game?
| 7 vans | |
| 4 vans | |
| 5 vans | |
| 10 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{31}{9} \) = 3\(\frac{4}{9}\)
So, it will take 3 full vans and one partially full van to transport the entire team making a total of 4 vans.
Jennifer scored 84% on her final exam. If each question was worth 3 points and there were 150 possible points on the exam, how many questions did Jennifer answer correctly?
| 43 | |
| 42 | |
| 48 | |
| 28 |
Jennifer scored 84% on the test meaning she earned 84% of the possible points on the test. There were 150 possible points on the test so she earned 150 x 0.84 = 126 points. Each question is worth 3 points so she got \( \frac{126}{3} \) = 42 questions right.
The total water usage for a city is 30,000 gallons each day. Of that total, 14% is for personal use and 43% is for industrial use. How many more gallons of water each day is consumed for industrial use over personal use?
| 3,000 | |
| 10,850 | |
| 2,900 | |
| 8,700 |
43% of the water consumption is industrial use and 14% is personal use so (43% - 14%) = 29% more water is used for industrial purposes. 30,000 gallons are consumed daily so industry consumes \( \frac{29}{100} \) x 30,000 gallons = 8,700 gallons.
Bob loaned Betty $700 at an annual interest rate of 7%. If no payments are made, what is the total amount owed at the end of the first year?
| $714 | |
| $763 | |
| $721 | |
| $749 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $700
i = 0.07 x $700
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $700 + $49A triathlon course includes a 200m swim, a 30.7km bike ride, and a 14.7km run. What is the total length of the race course?
| 41.5km | |
| 55.7km | |
| 45.6km | |
| 61.3km |
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 200 meters to kilometers, divide the distance by 1000 to get 0.2km then add the remaining distances:
total distance = swim + bike + run
total distance = 0.2km + 30.7km + 14.7km
total distance = 45.6km
