If a mayor is elected with 81% of the votes cast and 58% of a town's 21,000 voters cast a vote, how many votes did the mayor receive?
| 8,770 | |
| 7,064 | |
| 9,866 | |
| 10,718 |
If 58% of the town's 21,000 voters cast ballots the number of votes cast is:
(\( \frac{58}{100} \)) x 21,000 = \( \frac{1,218,000}{100} \) = 12,180
The mayor got 81% of the votes cast which is:
(\( \frac{81}{100} \)) x 12,180 = \( \frac{986,580}{100} \) = 9,866 votes.
In a class of 34 students, 13 are taking German and 15 are taking Spanish. Of the students studying German or Spanish, 9 are taking both courses. How many students are not enrolled in either course?
| 14 | |
| 15 | |
| 28 | |
| 18 |
The number of students taking German or Spanish is 13 + 15 = 28. Of that group of 28, 9 are taking both languages so they've been counted twice (once in the German group and once in the Spanish group). Subtracting them out leaves 28 - 9 = 19 who are taking at least one language. 34 - 19 = 15 students who are not taking either language.
How many 1\(\frac{1}{2}\) gallon cans worth of fuel would you need to pour into an empty 15 gallon tank to fill it exactly halfway?
| 2 | |
| 8 | |
| 5 | |
| 10 |
To fill a 15 gallon tank exactly halfway you'll need 7\(\frac{1}{2}\) gallons of fuel. Each fuel can holds 1\(\frac{1}{2}\) gallons so:
cans = \( \frac{7\frac{1}{2} \text{ gallons}}{1\frac{1}{2} \text{ gallons}} \) = 5
Find the average of the following numbers: 16, 12, 15, 13.
| 17 | |
| 14 | |
| 10 | |
| 15 |
To find the average of these 4 numbers add them together then divide by 4:
\( \frac{16 + 12 + 15 + 13}{4} \) = \( \frac{56}{4} \) = 14
