On average, the center for a basketball team hits 45% of his shots while a guard on the same team hits 60% of his shots. If the guard takes 25 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
56
30
33
68

Solution
If the guard hits 60% of his shots and takes 25 shots he'll make:

guard shots made = shots taken x \( \frac{\text{% made}}{100} \) = 25 x \( \frac{60}{100} \) = \( \frac{60 x 25}{100} \) = \( \frac{1500}{100} \) = 15 shots

The center makes 45% 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 = \( \frac{15}{\frac{45}{100}} \) = 15 x \( \frac{100}{45} \) = \( \frac{15 x 100}{45} \) = \( \frac{1500}{45} \) = 33 shots

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


2

What is \( 9 \)\( \sqrt{175} \) + \( 7 \)\( \sqrt{7} \)

35% Answer Correctly
63\( \sqrt{25} \)
52\( \sqrt{7} \)
63\( \sqrt{1225} \)
16\( \sqrt{7} \)

Solution

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

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

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

45\( \sqrt{7} \) + 7\( \sqrt{7} \)
(45 + 7)\( \sqrt{7} \)
52\( \sqrt{7} \)


4

Find the average of the following numbers: 8, 4, 8, 4.

74% Answer Correctly
4
9
8
6

Solution

To find the average of these 4 numbers add them together then divide by 4:

\( \frac{8 + 4 + 8 + 4}{4} \) = \( \frac{24}{4} \) = 6


5

What is the next number in this sequence: 1, 3, 7, 13, 21, __________ ?

69% Answer Correctly
28
26
31
36

Solution

The equation for this sequence is:

an = an-1 + 2(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 + 2(6 - 1)
a6 = 21 + 2(5)
a6 = 31
