a) Maria walked 420m
b) Walter walked 323m
c) Maria walked 97m further.
c² - b² = a²
80² -79² = a²
6400 - 6241 = a²
159 = a²
√159 = √a²
12.6 = a
The minimum distance is 279.1cm and the maximum distance is 291.7cm
Great post Paulo, I liked that you explained your answer in a easy way using pythagorean relationship. Although for number 11 i saw that for the pictures both of them have the same hypotenuse. Overall, I liked the video but try to get a link next time.
ReplyDeleteGreat job Paulo. I liked that you changed the colour of the important words. You have a great video and link and you did a good job explaining the questions. But how did you get 3,b)? when I did it my answer was over 1000, I have no clue how I got that. Could you explain that please. Other than that it was a very good post.
ReplyDeleteGood job, Paulo. I liked how you used the pictures from the book. It was really helpful in terms of reference. You could have shown the work for question 3, though.
ReplyDeletePaul, there is a link.. UNDER THE VIDEO.
ReplyDeleteOH, WHOOPS. I forgot to put my work for question 3.. i'll just edit tomorrow and add it ok? :)
thanks paulo! I missed the homework so your post was really helpful!
ReplyDeleteGreat job Paulo. I really like the pictures. Also it looks very neat but for number three you should show your work. Other than that, great job.
ReplyDeletePaulo, great job! But aren't I suppose to do questions 3, 9, 13? Overall your post was great and I really liked the pictures. Next time try adding a link.
ReplyDeleteGood job, Paulo. But you used the wrong formula. You are trying to find a2, not b2. So the formula would be c2-b2=a2, not c2-a2=b2.
ReplyDeleteNice job Paulo! Your post was very good, I liked the pictures you used, but I agree with Julibella, you used the wrong formula, but thats okay, all those formulas can be complicated to remember. Overall, great job!
ReplyDeleteGreat job, Paulo. I liked how you used pictures from the math booklet. The colors also made your post outstanding. Next time, add a link. Other than that, good job.
ReplyDeleteGood Job, very outstanding!
