We know that
if P is the centroid of triangle ABC
so
PD=(1/3)*BD
BD=3*PD-----> BD=3*3-----> BD=9 units
the answer is
BD=9 units

Answer:
y=-0.5ˣ
Step-by-step explanation:
each time the x-value is increased by one, the y-value is cut in half compared to the previous point
23.
2/5 + 1/2
you find the common denominator
which is 10
4/10 + 5/10
you add the fractions

Answer:
2880 in³
Step-by-step explanation:
Assume the steps have the dimensions shown in the diagram below.
We can decompose them into two rectangular prisms.
The lower prism has the dimensions 20 in × 16 in × 6 in.
The upper prism has the dimensions 20 in × 8 in × 6 in.
1. Volume of lower prism
V = lwh = 20 in × 16 in × 6 in = 1920 in³
2. Volume of upper prism
V = lwh = 20 in × 8 in × 6 in = 960 in³
3. Volume of steps
V = 1920 in³ + 960 in³ = 2880 in³
