Answer:
V = 90 cm^3
Step-by-step explanation:
The volume is given by
V = Bh
where B is the area of the base and h is the height
The base is the two sides that are identical, which is the triangle
B = 1/2 bh
= 1/2 (4*3)
= 1/2 (12)
= 6
Substituting into the volume equation, where h = 15
V = 6*15
V = 90 cm^3
What you have so far is perfect. You started with the given statements and then use the definition of midpoint to show that each piece is equal to one another.
From here, use the transitive property
We combine these two statements
into the following
WX = YZ
So we can effectively say WX = XY = YZ meaning the segments WX, XY and YZ are all the same length.
Through similar logic, we can chain together
to get VW = XY
-------------
Consequently this means VW, WX, XY, and YZ are all the same length
Let's call that length m.
m = length of segment VW = length of WX = etc etc
This means,
VY = VW+WX+XY = m+m+m = 3m
and
WZ = WX+XY+YZ = m+m+m = 3m
Both VY and WZ are exactly 3m units long, therefore, VY = WZ
ninety four means $94. 36/100 means $0.36. when you put these together you get $94.36
Answer:
5.5 miles over 2 hours--> 5.5/2= 2.75 miles per hour was his average walking speed. 5.5 miles over 2.5 hours --> 5.5/2.5= 2.2 miles per hour on the return trip meaning that his average speed was (2.75-2.2= 0.55) 0.55 miles per hour lower on the return trip
Step-by-step explanation:
I hope this helps you :)
