문제1
For any whole number x>0, how many elements are in the set that contains only the numbers that are
multiples AND factors of x?
For any whole number x>0, how many elements are in the set that contains only the numbers that are
multiples AND factors of x?
정답:
1
Explanation/Reference:
The largest factor of a positive, whole number is itself, and the smallest multiple of a positive, whole
number is itself. Therefore, the set of only the factors and multiples of a positive, whole number contains
one element-the number itself.

Stephanie buys almonds at the grocery store for $1.00 per pound. If she buys 4 pounds of almonds and
pays a 5% tax on her purchase, what is Stephanie's total bill?
Stephanie buys almonds at the grocery store for $1.00 per pound. If she buys 4 pounds of almonds and
pays a 5% tax on her purchase, what is Stephanie's total bill?
정답:
4.20
Explanation/Reference:
If one pound of almonds costs $1.00, then 4 pounds of almonds costs 4($1.00) = $4.00. If Stephanie pays
a 5% tax, then she pays ($4.00)(0.05) = $0.20 in tax. Her total bill is $4.00 + $0.20 = $4.20.

The length of a rectangular prism is four times the height of the prism and one-third the width of the prism.
If the volume of the prism is 384in3, what is the width of the prism?
The length of a rectangular prism is four times the height of the prism and one-third the width of the prism.
If the volume of the prism is 384in3, what is the width of the prism?
정답:
24
Explanation/Reference:
If the height of the prism is h, then the length of the prism is four times that, 4h. The length is one-third of
the width, so the width is three times the length: 12h. The volume of the prism is equal to its length
multiplied by its width multiplied by its height:
The height of the prism is 2 in, the length of the prism is (2 in)(4) = 8 in, and the width of the prism is (8 in)
(3) = 24 in.

In the circle above, the measure of angle AOB is 80 degrees and the length of arc AB is 28(Pi) units. What is
the radius of the circle?
In the circle above, the measure of angle AOB is 80 degrees and the length of arc AB is 28(Pi) units. What is
the radius of the circle?
정답:
63
Explanation/Reference:
The size of an intercepted arc is equal to the measure of the intercepting angle divided by360, multiplied
by the circumference of the circle (2(Pi)r, where r is the radius of the circle):
units.

문제9
There are 750 students in the auditorium for an assembly. When the assembly ends, the students begin
to leave. If 32% of the students have left so far, how many students are still in the auditorium?
There are 750 students in the auditorium for an assembly. When the assembly ends, the students begin
to leave. If 32% of the students have left so far, how many students are still in the auditorium?
정답:
510
Explanation/Reference:
If 32% of the students have left the auditorium, then 100 - 32 = 68% of the students are still in the
auditorium; 68% of 750 = (0.68)(750) = 510 students.

If 32% of the students have left the auditorium, then 100 - 32 = 68% of the students are still in the
auditorium; 68% of 750 = (0.68)(750) = 510 students.
