Answer:
The fraction of wood used for horizontal support is
.
Step-by-step explanation:
Assume that the total piece of wood is of length 1.
It is provided that Talia used
of the piece of wood for the base of he project.
She use
of the piece of wood for the for the vertical support.
The remaining wood she used for horizontal support.
The amount of wood used for horizontal support can be computed by the subtracting the amount of wood used for base of the project and vertical support form 1.
Compute the amount of wood used for horizontal support as follows:

Thus, the fraction of wood used for horizontal support is
.
Answer:
y = 6
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 9, then
k =
=
=
, thus
y =
x ← equation of variation
When x = 18, then
y =
× 18 =
= 6
The three interior angles of any triangle add to 180 degress. Therefore,
180-(120 + 40) = the third angle.
So, 20 is the third angle
8/12 is still owed, and when you simplify the fraction it becomes 2/3
