If a mayor is elected with 90% of the votes cast and 30% of a town's 33,000 voters cast a vote, how many votes did the mayor receive?
| 5,346 | |
| 6,435 | |
| 8,910 | |
| 8,613 |
If 30% of the town's 33,000 voters cast ballots the number of votes cast is:
(\( \frac{30}{100} \)) x 33,000 = \( \frac{990,000}{100} \) = 9,900
The mayor got 90% of the votes cast which is:
(\( \frac{90}{100} \)) x 9,900 = \( \frac{891,000}{100} \) = 8,910 votes.
What is \( \sqrt{\frac{4}{4}} \)?
| 1 | |
| 4\(\frac{1}{2}\) | |
| \(\frac{5}{7}\) | |
| 1\(\frac{1}{3}\) |
To take the square root of a fraction, break the fraction into two separate roots then calculate the square root of the numerator and denominator separately:
\( \sqrt{\frac{4}{4}} \)
\( \frac{\sqrt{4}}{\sqrt{4}} \)
\( \frac{\sqrt{2^2}}{\sqrt{2^2}} \)
1
What is \( \frac{3y^6}{7y^4} \)?
| 2\(\frac{1}{3}\)y2 | |
| \(\frac{3}{7}\)y1\(\frac{1}{2}\) | |
| \(\frac{3}{7}\)y2 | |
| \(\frac{3}{7}\)y-2 |
To divide terms with exponents, the base of both exponents must be the same. In this case they are so divide the coefficients and subtract the exponents:
\( \frac{3y^6}{7y^4} \)
\( \frac{3}{7} \) y(6 - 4)
\(\frac{3}{7}\)y2
The __________ is the greatest factor that divides two integers.

The greatest common factor (GCF) is the greatest factor that divides two integers.
Which of the following statements about exponents is false?
all of these are false |
|
b1 = 1 |
|
b1 = b |
|
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).
