So today we corrected right angle problems and the mean, median, and mode problem. Then, we were given 3 problems to solve using the Pythagoras theorem. TEST : THURSDAY. These problems will help you better on the test.

By the way, √ <-- this means the square root. Question 1:
a^2+b^2=c^2
a^2+2^2=8^2
-2^2 -2^2
a^2=8^2-2^2
a^2=64-4
a^2=60
√a^2=√60
a=7.745

Question 2:

a^2+b^2=c^2
a^2+13^2=20^2
-13^2 -13^2
a^2=20^2-13^2
a^2=400-169
a^2=331
√a^2=√331
a=18.193

Question 3:

a^2+b^2=c^2
6^2+b^2=23^2
-6^2 -6^2
b^2=23^2-6^2
b^2=529-36
b^2=493
√b^2=√493
b=22.206

After, we were given these questions:

I can't really help you on this because I don't understand the last 2 questions.

But the first questions answer is : 1/3

Thank you for reading! Tomorrow is my last day! Comment!

good job ont the blog. I think you need to make a probability tree to answer it.

LEOMAR :(
GREAT SCRIBE POST. WAS THIS THE LAST ONE YOU MADE BEFORE YOU LEFT? ANYWAYS ANYWAYS ANYWAYS, I liked how you mentioned to everyone that there will be a test on that day, even though it passed already. I'm sure that these triangles and examples and yada helped many people in your class prepare for their test. *i wish someone in our class did that, or atleast I saw your scribe before that day..* Your pictures of the questions were well done. They were plain, but that's FINE. Because it's just a triangle that's labelled A, B, C with the numbers! Haha. For the first question, when you were solving it.. I kind of got confused, when you wrote down "a^2+b^2=c^2, a^2+2^2=8^2, -2^2 -2^2" Well, actually it was only the third sentence. I still don't get it right now.. really.. maybe it's just me though. Bobby did say I was slow. Anyways, when you got the answer for A, 7.745 I think you should have made another square and labelled all the parts, incuding A. So that you'll get use to it, and the people reading your scribe would get use to it. {Since it costs you marks on the test). Or you could just simply add it to the first square. All your triangle questions were great, just remember to put the answers that you found by using the pythaogrean theorem on the triangles. For the last question..s, it's okay if you don't understand it! Atleast you posted it. I'll help you with the last two, so that when you come back you will be .. uhm.. yea. :) Okay. The question is asking "How many possible choices if she travels by train?" The way you could answer this, is by making a Probability Tree. Actually, always make a tree. It'll always help you. Okay. So, wait hold on. I'll look for the picture. I can't add pictures to this comment, but go to http://sargentparkmathzone.blogspot.com/, then scroll down to the march 4 scribe post. Harbeck made a probability tree, and he circled all the possible choices if she choices train. Which is trip > friend hotel x 2. I think. I'm kind of confused now because of his pictures. But, that's basically how you can do it easily. Make a tree, and write down everything. It'll help you! The chances of Billy going to Calgary on a train to meet a friend is 1/18. 5.5%. How? Well, if you draw a tree, youll look at the Calgary section and see that Bill'ys Chances of doing those things, are 1/18, because it is only written there once. It is also on the Math Blog. Sorry If this didn't make sense! :| Good jooob! Your work was well done and very neat, like always! Keep it up Leomar! Please have safe safe trip, we miss you! Come back. QUESTION, ANSWER ME WHEN YOU COME BACK FROM THE PHILIPPINES! :(: How do you make the square root sign? S:
