Name________________________________
Instructions: The quiz is worth 50 points. There are 10 problems, each worth 5 points. Your score on
the quiz will be converted to a percentage and posted in your assignment folder with
comments.
This quiz allows open book and open notes, and you may take as long as you like on it
provided that you submit the quiz no later than the due date posted in our course schedule
of the syllabus.
You should show all of your work to receive full credit. If you do not show work, you
may earn only partial or no credit.
Please type your work in your copy of the quiz, or if you prefer, create a document

the document. Review instructions for submitting your quiz in the Quizzes Module. Please remember to show ALL of your work on every problem.
1) Tanya has a triangular garden bed in her back yard. The measure of the second angle is 50°
more than the measure of the first angle. The measure of the third angle is 30° less than twice
the measure of the first. Find the measures of the three angles. Start your work by defining the
unknown quantities in terms of a variable. Show all work and write a complete answer,
including units. 2) Jacob decided to ride his bicycle across the country during his 3-month summer vacation. The
route he took from Washington, DC to Portland, Oregon, covered a total of 4420 miles. To keep
his mind occupied during some of the long flat stretches of countryside, he often did algebra
problems in his head. One day, for example, he determined that his distance from his starting
point was exactly 50 miles more than three times the distance remaining until the finishing point.
How far was Jacob from the finishing point of his journey when he made that calculation? Start
your work by defining the unknown quantities in terms of a variable. Show all work and write a
complete answer, including units. Math 009

CD paying 9% annual simple interest, at what rate does the remainder of her money need to be
invested so that the two investments together yield at least $1500 in yearly simple interest? (Set
up and solve an inequality to answer this question). Round to the nearest cent as needed. y 9) Given the equation below, find four ordered pair solutions by completing the table, showing
