If a mayor is elected with 82% of the votes cast and 35% of a town's 44,000 voters cast a vote, how many votes did the mayor receive?
| 12,628 | |
| 10,780 | |
| 11,858 | |
| 12,012 |
If 35% of the town's 44,000 voters cast ballots the number of votes cast is:
(\( \frac{35}{100} \)) x 44,000 = \( \frac{1,540,000}{100} \) = 15,400
The mayor got 82% of the votes cast which is:
(\( \frac{82}{100} \)) x 15,400 = \( \frac{1,262,800}{100} \) = 12,628 votes.

If \( \left|a - 3\right| \) + 3 = -7, which of these is a possible value for a?
| -17 | |
| -15 | |
| 5 | |
| 13 |
First, solve for \( \left|a - 3\right| \):
\( \left|a - 3\right| \) + 3 = -7
\( \left|a - 3\right| \) = -7 - 3
\( \left|a - 3\right| \) = -10
The value inside the absolute value brackets can be either positive or negative so (a - 3) must equal - 10 or --10 for \( \left|a - 3\right| \) to equal -10:
| a - 3 = -10 a = -10 + 3 a = -7 | a - 3 = 10 a = 10 + 3 a = 13 |
So, a = 13 or a = -7.
A tiger in a zoo has consumed 90 pounds of food in 9 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 150 pounds?
| 13 | |
| 6 | |
| 4 | |
| 8 |
If the tiger has consumed 90 pounds of food in 9 days that's \( \frac{90}{9} \) = 10 pounds of food per day. The tiger needs to consume 150 - 90 = 60 more pounds of food to reach 150 pounds total. At 10 pounds of food per day that's \( \frac{60}{10} \) = 6 more days.
