1

What is \( \sqrt{\frac{64}{25}} \)?

70% Answer Correctly
2\(\frac{2}{3}\)
1\(\frac{3}{4}\)
1
1\(\frac{3}{5}\)

Solution

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:

\( \sqrt{\frac{64}{25}} \)
\( \frac{\sqrt{64}}{\sqrt{25}} \)
\( \frac{\sqrt{8^2}}{\sqrt{5^2}} \)
\( \frac{8}{5} \)
1\(\frac{3}{5}\)


2

If a mayor is elected with 71% of the votes cast and 73% of a town's 24,000 voters cast a vote, how many votes did the mayor receive?

49% Answer Correctly
10,687
12,439
11,563
11,213

Solution

If 73% of the town's 24,000 voters cast ballots the number of votes cast is:

(\( \frac{73}{100} \)) x 24,000 = \( \frac{1,752,000}{100} \) = 17,520

The mayor got 71% of the votes cast which is:

(\( \frac{71}{100} \)) x 17,520 = \( \frac{1,243,920}{100} \) = 12,439 votes.

What is the next number in this sequence: 1, 5, 13, 25, 41, __________ ?

69% Answer Correctly
69
64
61
54

Solution

The equation for this sequence is:

an = an-1 + 4(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 + 4(6 - 1)
a6 = 41 + 4(5)
a6 = 61

The total water usage for a city is 30,000 gallons each day. Of that total, 29% is for personal use and 45% is for industrial use. How many more gallons of water each day is consumed for industrial use over personal use?

58% Answer Correctly
4,250
11,700
11,600
4,800

Solution

45% of the water consumption is industrial use and 29% is personal use so (45% - 29%) = 16% more water is used for industrial purposes. 30,000 gallons are consumed daily so industry consumes \( \frac{16}{100} \) x 30,000 gallons = 4,800 gallons.


5

What is \( \frac{-7z^5}{3z^2} \)?

60% Answer Correctly
-\(\frac{3}{7}\)z7
-2\(\frac{1}{3}\)z10
-2\(\frac{1}{3}\)z3
-\(\frac{3}{7}\)z3

Solution

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:

\( \frac{-7z^5}{3z^2} \)
\( \frac{-7}{3} \) z(5 - 2)
-2\(\frac{1}{3}\)z3
