Practice Test for Exam 3 – 2.6 & 3.1-3.2
Due (optional) Test Day – Mon., 11/3/2014
This practice test will give you a good idea of the type and number of problems you will see on the
actual test. Working through this practice test will, therefore, provide you with a good idea of how
well you know the material you will be tested over. I am providing the answers on the last sheet for
you to check your answers.
You have the opportunity to earn 3 extra credit points toward your test grade if you show all
work for all the problems and, of course, get all the answers correct (partial points can be earned
as well). If you would like to earn these extra points, you will need to turn in this packet, with
your work attached (on your own notebook paper), on test day.
I will be including 5-6 Cumulative Review problems at the beginning this time. These
problems will be like the Problems on the Cumulative Review Worksheets you’ve had and/or like
Cumulative Review type problems assigned in Homework assignments…
p149: #119-122,
p193: #136-138, 140
p204: #75-77
In terms of points possible, you should expect the application problems to be worth a little more
than the others…..
Remember, also, ….. you are allowed to use a calculator with this test!!!!!
ALSO – at the end of the Practice Test Questions, but before the Answers, I will be including a
“Formula/Fact Sheet” like what I will be including in the actual text.
One more thing – attached to the very back of this packet, you will see a sample of what the
application problems will look like on the test…… I don’t want you to be surprised!
Practice Test questions continued on next page!

(I will include one like this with the test too!)
Perimeter, P, is the sum of the lengths of the sides of a figure.
Area, A, is the total surface within the figure’s boundaries.

P = 4s
A= s

calculator, you will need to round your answers to the nearest
hundredth.)

Two angles are supplementary angles when the sum of their
measures is 180 . Each angle is the supplement of the other.
Perpendicular lines are lines that intersect at 90 angles.
An acute triangle is one with three acute angles (angles < 90 ).
An obtuse triangle has one obtuse angle (an angle > 90 ).
A right triangle has one right angle (an angle equal to 90 ).
An isosceles triangle has two sides of equal length. The
angles opposite the equal sides have the same measure.
An equilateral triangle has three sides of equal length. It also
has three equal angles that measure 60 each.
When two sides of a right triangle are known, the third side
can be found using the Pythagorean Theorem, a 2 + b 2 =
c 2 , where a and b are the legs and c is the hypotenuse of the
triangle.
A triangle that contains two sides of equal length is called an
isosceles triangle. In isosceles triangles, the angles opposite the
two sides of equal length have equal measures.
The sum of the angles of any triangle measures 180 degrees.
When two lines intersect four angles are formed. The pair of
opposite angles formed by the intersecting lines are called
vertical angles. Vertical angles have equal measures.
A quadrilateral is a four-sided figure. Quadrilaterals include
squares, rectangles, parallelograms, and trapezoids. The sum
of the measures of the angles of any quadrilateral is 360
degrees.
Two angles are complementary angles when the sum of their
measures is 90 . Each angle is the complement of the other.

x = average test score, x – 12 = Justin’s score
x = Kristen’s bill (or Kyle’s), 54.35 – x = Kyle’s bill (or Kristen’s)
x = length, ½ x – 5 = width
Female fans = 1200 – m
Larger number = 3n + 2, so Sum of the two numbers = n + 3n + 2
Complete purchase total = x + .065x
Define:
x = smaller integer
2x + 7 = larger integer
Equation: x + 2x + 7 = 121
Solve:
x = 38
Answer: The integers are 38 & 83.
Define:
x = first consecutive integer
x + 1 = second consecutive integer
Equation: x + x + 1 = 69
Solve:
x = 34
Answer: The consecutive integers are 34 & 35.
Define:
x = cost of mower before tax
.08x = tax on mower
Equation: x + .08x = 648
Solve:
x = 600
Answer: The cost of the mower before tax was $600.
Define:
x = years
Equation: 808 + 112x = 2264
Solve:
x = 13
Answer: It would take 13 years.
Define:
x = number of candles Josephine ordered
Equation: 10.25x + 15 = 179
Solve:
x = 16
Answer: Josephine ordered 16 candles.
