14 members of a bridal party need transported to a wedding reception but there are only 2 5-passenger taxis available to take them. How many will need to find other transportation?

1

Solution

There are 2 5-passenger taxis available so that's 2 x 5 = 10 total seats. There are 14 people needing transportation leaving 14 - 10 = 4 who will have to find other transportation.

On average, the center for a basketball team hits 40% of his shots while a guard on the same team hits 55% of his shots. If the guard takes 30 shots during a game, how many shots will the center have to take to score as many points as the guard assuming each shot is worth the same number of points?

42% Answer Correctly
40
41
28
31

Solution
If the guard hits 55% of his shots and takes 30 shots he'll make:

guard shots made = shots taken x \( \frac{\text{% made}}{100} \) = 30 x \( \frac{55}{100} \) = \( \frac{55 x 30}{100} \) = \( \frac{1650}{100} \) = 16 shots

The center makes 40% of his shots so he'll have to take:

shots made = shots taken x \( \frac{\text{% made}}{100} \)
shots taken = \( \frac{\text{shots taken}}{\frac{\text{% made}}{100}} \)

to make as many shots as the guard. Plugging in values for the center gives us:

center shots taken = \( \frac{16}{\frac{40}{100}} \) = 16 x \( \frac{100}{40} \) = \( \frac{16 x 100}{40} \) = \( \frac{1600}{40} \) = 40 shots

to make the same number of shots as the guard and thus score the same number of points.

What is 4\( \sqrt{8} \) x 2\( \sqrt{8} \)?

41% Answer Correctly
64
8\( \sqrt{8} \)
6\( \sqrt{8} \)
6\( \sqrt{64} \)

Solution

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

4\( \sqrt{8} \) x 2\( \sqrt{8} \)
(4 x 2)\( \sqrt{8 \times 8} \)
8\( \sqrt{64} \)

Now we need to simplify the radical:

8\( \sqrt{64} \)
8\( \sqrt{8^2} \)
(8)(8)
64

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

56% Answer Correctly

commutative property for multiplication

distributive property for division

commutative property for division

distributive property for multiplication


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, \({a^3 + 6a^2 \over a^2} = {a^3 \over a^2} + {6a^2 \over a^2} = a + 6\).

A machine in a factory has an error rate of 8 parts per 100. The machine normally runs 24 hours a day and produces 10 parts per hour. Yesterday the machine was shut down for 5 hours for maintenance.

How many error-free parts did the machine produce yesterday?

48% Answer Correctly
169
79.1
121
174.8

Solution

The hourly error rate for this machine is the error rate in parts per 100 multiplied by the number of parts produced per hour:

\( \frac{8}{100} \) x 10 = \( \frac{8 \times 10}{100} \) = \( \frac{80}{100} \) = 0.8 errors per hour

So, in an average hour, the machine will produce 10 - 0.8 = 9.2 error free parts.

The machine ran for 24 - 5 = 19 hours yesterday so you would expect that 19 x 9.2 = 174.8 error free parts were produced yesterday.
