Which of the following statements about exponents is false?

47% Answer Correctly

b1 = b

all of these are false

b1 = 1

b0 = 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).

Cooks are needed to prepare for a large party. Each cook can bake either 3 large cakes or 14 small cakes per hour. The kitchen is available for 4 hours and 40 large cakes and 330 small cakes need to be baked.

How many cooks are required to bake the required number of cakes during the time the kitchen is available?

41% Answer Correctly
7
11
9
10

Solution

If a single cook can bake 3 large cakes per hour and the kitchen is available for 4 hours, a single cook can bake 3 x 4 = 12 large cakes during that time. 40 large cakes are needed for the party so \( \frac{40}{12} \) = 3\(\frac{1}{3}\) cooks are needed to bake the required number of large cakes.

If a single cook can bake 14 small cakes per hour and the kitchen is available for 4 hours, a single cook can bake 14 x 4 = 56 small cakes during that time. 330 small cakes are needed for the party so \( \frac{330}{56} \) = 5\(\frac{25}{28}\) cooks are needed to bake the required number of small cakes.

Because you can't employ a fractional cook, round the number of cooks needed for each type of cake up to the next whole number resulting in 4 + 6 = 10 cooks.

What is \( 7 \)\( \sqrt{175} \) + \( 5 \)\( \sqrt{7} \)

35% Answer Correctly
12\( \sqrt{25} \)
40\( \sqrt{7} \)
12\( \sqrt{175} \)
12\( \sqrt{1225} \)

Solution

To add these radicals together their radicands must be the same:

7\( \sqrt{175} \) + 5\( \sqrt{7} \)
7\( \sqrt{25 \times 7} \) + 5\( \sqrt{7} \)
7\( \sqrt{5^2 \times 7} \) + 5\( \sqrt{7} \)
(7)(5)\( \sqrt{7} \) + 5\( \sqrt{7} \)
35\( \sqrt{7} \) + 5\( \sqrt{7} \)

Now that the radicands are identical, you can add them together:

35\( \sqrt{7} \) + 5\( \sqrt{7} \)
(35 + 5)\( \sqrt{7} \)
40\( \sqrt{7} \)


4

How many 8-passenger vans will it take to drive all 98 members of the football team to an away game?

81% Answer Correctly
13 vans
5 vans
6 vans
7 vans

Solution

Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:

vans = \( \frac{98}{8} \) = 12\(\frac{1}{4}\)

So, it will take 12 full vans and one partially full van to transport the entire team making a total of 13 vans.


5

Simplify \( \frac{16}{64} \).

77% Answer Correctly
\( \frac{2}{3} \)
\( \frac{8}{11} \)
\( \frac{4}{17} \)
\( \frac{1}{4} \)

Solution

To simplify this fraction, first find the greatest common factor between them. The factors of 16 are [1, 2, 4, 8, 16] and the factors of 64 are [1, 2, 4, 8, 16, 32, 64]. They share 5 factors [1, 2, 4, 8, 16] making 16 their greatest common factor (GCF).

Next, divide both numerator and denominator by the GCF:

\( \frac{16}{64} \) = \( \frac{\frac{16}{16}}{\frac{64}{16}} \) = \( \frac{1}{4} \)
