Question: Which of the following expresses 3/16
3
16
as a percent?
A. 0.1875%
B. 1.875%
C. 5.33%
D. 18.75%
Correct Answer: D
Option (D) is correct. The question requires an understanding of percent and
percentages. To convert a fraction to a percent, it is necessary to multiply the fraction by
100 and add a percent symbol. Since 316×100=18.75
3
16 × 100 = 18.75,
3
16
is equivalent to 18.75%.
,Which of the following is equal to 4(5−2)^2 − 2^3
(^ means the digit after ^ is an exponent)
A. 16
B. 28
C. 76
D.136
Option (B) is correct. The question requires an understanding of the order of operations.
The first step to simplify the expression
4(5−2)^2 − 2^3
is the evaluation of the subtraction within the parentheses; the expression is equivalent
to
4 × 3^2 − 2^3
The second step is the evaluation of the powers; the expression is equivalent to 4×9−8
The third step is the evaluation of the multiplication; the expression is equivalent to 36−8
The final step is the evaluation of the subtraction; the expression is equivalent to 28.
A two-dimensional net of a certain three-dimensional figure includes five faces,
nine edges, and six vertices. Which of the following three-dimensional figures is
represented by the net?
A. Triangular pyramid
B. Triangular prism
C. Rectangular pyramid
D. Rectangular prism
, Option (B) is correct. The question requires an understanding of three-dimensional
geometry.
Triangular pyramids and rectangular prisms have four and six faces, respectively.
Triangular prisms have five faces: two are triangles, and three are quadrilaterals.
Rectangular pyramids also have five faces: one is a rectangle, and four are triangles.
Triangular prisms have nine edges, while rectangular pyramids only have eight edges.

Bobby runs a small store. The total number of customers who shopped at the
store during each of nine consecutive weeks is recorded in the chart shown. If
the number of customers who shopped at the store during the tenth week were
included in the data, the mean and median of the data would change but the
range would not change. Which of the following could be the number of
customers who shopped at the store during the tenth week?
