Kathleen's Scribepost for January 4,2010

Question # 3.



a) 20 cm

a2 + b2 = c2

a2=12cm=144cm
b2=16cm=256cm
c2=?=?

144cm+256cm=c2
144cm+256cm
=400cm

c2=20cm

400's square root is 20cm.


b) 34 cm

p2 + q2 = r2

p2=16m=256m
q2=30m=900m
r2=?=?

256m+900m=r2
256m+900m=1156m

r2=34cm

1156's square root is 34cm.




Question # 4.









a) 9.2 cm

x2 + y2 = z2


x2=6cm=36cm
y2=7cm=49cm
z2=?=?

49cm + 36cm = z2
49cm + 36cm = 85

z2 = 9.2 cm

85's square root is 9.2 cm.


b) 13.6 cm

b2 + c2 = d2

b2=8cm=64cm
c2=11cm=121cm
d2=?=?

64cm + 121cm = d2
64cm + 121cm = 185cm

d2=13.6cm

185's square root is 13.6 cm.

goodjob Kathleen but i was kind of confused at question 3 because i didn't know the question so you should put that in but than that your scribe was very good.

i agree with kamille on question 3.
and also on question 4.. you lost me there. shouldnt it be like :

a)
x² + y²= z²
6² + 7²= z²
(6x6) + (7x7) = z²
36 + 49 = z²
85 = z²
√85 = √z²
9.2 = z²

kk, i wont put part b, because ill let you do do it yourself part a, was just an example.
