What is the next number in this sequence: 1, 9, 17, 25, 33, __________ ?
| 39 | |
| 35 | |
| 41 | |
| 36 |
The equation for this sequence is:
an = an-1 + 8
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 8
a6 = 33 + 8
a6 = 41
Jennifer scored 94% on her final exam. If each question was worth 4 points and there were 200 possible points on the exam, how many questions did Jennifer answer correctly?
| 47 | |
| 62 | |
| 34 | |
| 39 |
Jennifer scored 94% on the test meaning she earned 94% of the possible points on the test. There were 200 possible points on the test so she earned 200 x 0.94 = 188 points. Each question is worth 4 points so she got \( \frac{188}{4} \) = 47 questions right.
What is the next number in this sequence: 1, 3, 7, 13, 21, __________ ?
| 29 | |
| 25 | |
| 38 | |
| 31 |
The equation for this sequence is:
an = an-1 + 2(n - 1)
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 2(6 - 1)
a6 = 21 + 2(5)
a6 = 31
Which of the following statements about exponents is false?
all of these are false |
|
b1 = b |
|
b1 = 1 |
|
b0 = 1 |
A number with an exponent (be) consists of a base (b) raised to a power (e). The exponent indicates the number of times that the base is multiplied by itself. A base with an exponent of 1 equals the base (b1 = b) and a base with an exponent of 0 equals 1 ( (b0 = 1).
If a mayor is elected with 70% of the votes cast and 48% of a town's 49,000 voters cast a vote, how many votes did the mayor receive?
| 19,992 | |
| 12,701 | |
| 20,698 | |
| 16,464 |
If 48% of the town's 49,000 voters cast ballots the number of votes cast is:
(\( \frac{48}{100} \)) x 49,000 = \( \frac{2,352,000}{100} \) = 23,520
The mayor got 70% of the votes cast which is:
(\( \frac{70}{100} \)) x 23,520 = \( \frac{1,646,400}{100} \) = 16,464 votes.
