Hey guys! Sorry that my post is really really late! Well anyways. On January 29, we had a math test. Our test was about scale diagrams, enlargements and reductions. In my opinion I thought some questions were easy, and some were quite hard. I didn't do so well on that test, but next test I will do better! :)
I'm gonna be choosing one question from each heading ex. multiple choice, short answer etc.
Multiple Choice
1. A scale of 2:5 means
a) there are 2 units of the image for every unit of actual size
b) there are 2 units of the image for every 5 units of actual size
c) there are 5 units of the image for every unit of actual size
d) there are 5 units of the image for every 2 units of actual size
ANSWER: B
Completion
7. The enlargement of an image is 3 times the size of the original. The value 3 represents the _________.
ANSWER: Scale Factor
Short Answer
11. In a drafting class, students must create reductions of actual objects for technical diagrams. Barry wants to use a scale factor of 0.25 to draw a machine part. If the actual object has a width of 100cm, what should the width of Barry's drawing be?
ANSWER:
100 x 0.25 = 25
The width of Barry's drawing should be 25cm.
Anyways, that's all the different parts to the test. There was only 16 questions. Please comment and help me make my post better! :)
