It's been like this for two years so I got used to it

Answer 12

If (the football team wins on FRI nite), then (practice is cancelled for MON.).
P=the football team wins on FRI nite and Q=practice is cancelled for MON

Answer 13

P= the football team won

Answer 14

so that would imply Q which is.....

practice is cancelled?

omg chill LOL! I blame it on my teacher o.o he makes everything look hard

Answer 18

remember law of detachment states you have to have a conditional statement If P, then Q and then know that P is true. Then you know Q is true

Answer 19

Answer 20

some teachers think math belongs in a secret club or something. lol. I am a teacher and i have seen it often

Answer 30

right now?

Answer 31

Yep, so glad my teacher didn't give me like 80 questions today. He usually gives that much

Answer 32

hmmm. 80 problems? that is a lot. fire away

Answer 33

Okay: If a triangle has one 90 degree angle, then the triangle is a right triangle. In DEF, m<E=90.

Answer 34

ok. that means the other two are compliments. so what is the question?

Answer 35

What do you mean what's the question? I'm looking for a conclusion using the Law of Detachment, same problem as I had before o.o

Answer 36

wooops.... missed the bus there.

Answer 37

omg teacher jokes stop it HAHAH

Answer 38

ok then lol

Answer 39

so you have if P, then Q. What are P and Q?

Answer 40

okay, P is 'a triangle has one 90 degree angle' and Q is 'the triangle is a right angle'

Answer 41

perfect. now, is the next statement related to P or to Q?

Answer 42

Yep!

Answer 43

which one?

Answer 44

you either have a restatement of P or a restatement of Q. Which is it?

Answer 45

OH um its P i think

Answer 46

why?

Answer 47

im confused now

Answer 48

you have the right answer

Answer 49

is it The triangle has one 90 degree angle, so it's a right triangle?

Answer 50

If a triangle has one 90 degree angle, then the triangleis a right triangle, AND triangle DEF has a right angle

Answer 51

so you have: if P, then Q AND P

Answer 52

law of detachment. :))

Answer 53

this implies Q, which is.........

Answer 54

more tea!

Answer 55

Wait, why do you have to add P again? We didn't do that on the football one o_o

Answer 56

yes we did.

Answer 57

law of detachment needs a conditional statement if P, then Q + a validation of P

Answer 58

No we didn't, we didn't add the "the football team won by 7 points on friday night.."

Answer 59

or a restatement of P. you can see that in the football statement

Answer 60

why after I message I can message again, I have to reload the page .-.

Answer 61

if the football team wins on FRI, then no practice on MON.+the football team won=no practice on monday

Answer 62

can't *

Answer 63

this thing has its share of glitches. sometimes i freeze and dont recover til i close the browser :(

Answer 64

ooooooooo..

Answer 65

if you scroll back up, you will see that you concluded that practice is cancelled in the footballl thingy

Answer 66

that was Q

Answer 67

brb

Answer 68

okayy

Answer 69

i have returned victorious. lol

Answer 70

omg teachers dont say that LOL

Answer 71

i guess i am just a little strange.

Answer 72

so did you see that the football one had an if P, then Q +P?

Answer 73

okay I guess i understand now.
Now there's another one: If the measures of two angles have a sum of 90 degree, then the angles are complementary. m<A+m<b=90

Answer 74

So the P: If the measures of two angles have a sum of 90 degrees
Q: Then the angles are complementary

Answer 75

right. it is good form to state P without the 'If' and Q without the 'then'

Answer 76

so what can you say about <A and <B?

Answer 77

oh okay, <A and <B are complementary

Answer 78

by definition, yes!

Answer 79

omg that is so nerdy AHAHA

Answer 80

because they are two angles the sum of whose measures is 90 degrees.

Answer 81

so are you comfy cozy with the law of detachment?

Answer 82

yes I know. Nope

Answer 83

so what's the conclusion for the problem ? o:

Answer 84

what is Q?

Answer 85

the angles are complemtary

Answer 86

yes.

Answer 87

OH then for the triangle one can I just put: DEF is a right triangle?

Answer 88

yes. had to scroll back and look.

Answer 89

then why'd you tell me to put a long sentence LOL

Answer 90

very nice. so, for the law of detachment, you have the conditional statement and then a restatement of P. you have to have both. that is why i made the long sentence.

Answer 91

if P, then Q AND P

Answer 92

that is the law of detachment

Answer 93

okay so for: If Robbie wants to save money to buy a car, he must get a part-time job. Robbie started a new job yesterday at a grocery store.

that's not possible right?

Answer 94

you are absolutely brilliant. you are right. this is a statement of IF P, THEN Q +Q, which tells us nothing. lol

Answer 95

i think you are getting this

Answer 96

YAY! no 'lol' o__o

Answer 97

oh no.... lol... sorry it just slipped out

Answer 98

there is not a single hint of a smile here
