If a mayor is elected with 84% of the votes cast and 42% of a town's 28,000 voters cast a vote, how many votes did the mayor receive?
| 7,291 | |
| 10,349 | |
| 8,702 | |
| 9,878 |
If 42% of the town's 28,000 voters cast ballots the number of votes cast is:
(\( \frac{42}{100} \)) x 28,000 = \( \frac{1,176,000}{100} \) = 11,760
The mayor got 84% of the votes cast which is:
(\( \frac{84}{100} \)) x 11,760 = \( \frac{987,840}{100} \) = 9,878 votes.
Which of the following is a mixed number?
\(1 {2 \over 5} \) |
|
\({7 \over 5} \) |
|
\({a \over 5} \) |
|
\({5 \over 7} \) |
A rational number (or fraction) is represented as a ratio between two integers, a and b, and has the form \({a \over b}\) where a is the numerator and b is the denominator. An improper fraction (\({5 \over 3} \)) has a numerator with a greater absolute value than the denominator and can be converted into a mixed number (\(1 {2 \over 3} \)) which has a whole number part and a fractional part.
4! = ?
4 x 3 |
|
5 x 4 x 3 x 2 x 1 |
|
3 x 2 x 1 |
|
4 x 3 x 2 x 1 |
A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
If a car travels 150 miles in 5 hours, what is the average speed?
| 50 mph | |
| 30 mph | |
| 25 mph | |
| 45 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)How many 1 gallon cans worth of fuel would you need to pour into an empty 6 gallon tank to fill it exactly halfway?
| 2 | |
| 6 | |
| 4 | |
| 3 |
To fill a 6 gallon tank exactly halfway you'll need 3 gallons of fuel. Each fuel can holds 1 gallons so:
cans = \( \frac{3 \text{ gallons}}{1 \text{ gallons}} \) = 3
