1

What is \( \frac{6\sqrt{32}}{2\sqrt{8}} \)?

71% Answer Correctly
3 \( \sqrt{\frac{1}{4}} \)
3 \( \sqrt{4} \)
\(\frac{1}{3}\) \( \sqrt{4} \)
\(\frac{1}{3}\) \( \sqrt{\frac{1}{4}} \)

Solution

To divide terms with radicals, divide the coefficients and radicands separately:

\( \frac{6\sqrt{32}}{2\sqrt{8}} \)
\( \frac{6}{2} \) \( \sqrt{\frac{32}{8}} \)
3 \( \sqrt{4} \)


2

If there were a total of 100 raffle tickets sold and you bought 3 tickets, what's the probability that you'll win the raffle?

60% Answer Correctly
12%
10%
15%
3%

Solution

You have 3 out of the total of 100 raffle tickets sold so you have a (\( \frac{3}{100} \)) x 100 = \( \frac{3 \times 100}{100} \) = \( \frac{300}{100} \) = 3% chance to win the raffle.


3

Which of the following is a mixed number?

82% Answer Correctly

\({5 \over 7} \)

\(1 {2 \over 5} \)

\({a \over 5} \)

\({7 \over 5} \)


Solution

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

Which of the following statements about exponents is false?

47% Answer Correctly

all of these are false

b0 = 1

b1 = b

b1 = 1


Solution

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).


5

\({b + c \over a} = {b \over a} + {c \over a}\) defines which of the following?

56% Answer Correctly

distributive property for multiplication

commutative property for multiplication

commutative property for division

distributive property for division


Solution

The distributive property for division helps in solving expressions like \({b + c \over a}\). It specifies that the result of dividing a fraction with multiple terms in the numerator and one term in the denominator can be obtained by dividing each term individually and then totaling the results: \({b + c \over a} = {b \over a} + {c \over a}\). For example, \({a^3 + 6a^2 \over a^2} = {a^3 \over a^2} + {6a^2 \over a^2} = a + 6\).
