UNIT 1 TEST PREP
GOTSK QUESTIONS??
You should be reviewing the questions on pages 68-73 (excepting section 1-8). ANY QUESTION from these pages is FAIR GAME for the test... ca-peesh??
Will the test have questions like number 23 on pg 73? You notice that 10 degrees celsius = 50 degrees fahrenheit, 20 degrees celsius = 68 degrees fahrenheit, and 30 degrees celsius = 80 degrees fahrenheit. Use inductive reasoning to predict the value in degrees fahrenheit for 40 degrees celsius. Btw I couldnt check my answers on the chapter test!! They werent in the back of the book?
I don't see why not... we did not explicitly discuss the meaning of "inductive reasoning" (you'll hear much more about this term next year in Geometry!), but basically it means can you infer/estimate, based on the previous observations, what the temp would be?... I think you probably can!
Select answers to Chapter Test on pg 73: (need more, just ask)
5) -40 6) -1/64 7) -7b 8) -25 9) 4/5 11) yes 14) 4x^2 (N.B. x^2 means 'x squared') 15) -16 16) 2-6t or -6t+2 17) -3b-21 or -21-3b 18a) rational numbers 18b) irrational numbers 19a) Distributive Prop 19b) Associative Prop of Addition 20) No, zero is non-negative but not positive 24) They will be equal if a>b>0 OR a<b<0 OR a=b
hmmm not too many questions... everyone must be pretty comfy with the material... I'm expecting some pretty good grades... btw I go to bed at 8pm (my beauty sleep calls)

ReplyDeleteThanks!
ReplyDeleteAnd how would you answer q # 7?
Couldn't you break the fraction, -7ab/a, into the PRODUCT of three fractions:
ReplyDelete(-7/1)(a/a)(b/1)
when you look at it that way, what is a better way to express the (a/a) factor?... 1, of course.
So the product can be rewritten as:
(-7/1)(1)(b/1)
or just -7b
ca-peesh??
Welcome to the magical & mystical number 1, one of your best friends this year!
I don't feel to good about this test..
ReplyDeleteI don't think there's a hw #2-2 so here's my question- is number 11 supposed to be a decimal..?
ReplyDeleteidk how 2 do #17
