Answer:
V = 396 cm³
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular face and h the height of prism )
A =
bh ( b is base and h perpendicular height )
here b = 9, h = 8 , then
A =
× 9 × 8 = 4.5 × 8 = 36 cm² , so
V = 36 × 11 = 396 cm³
The conclusion is valid
it is a systematic random sample
and the second one is a line graph (I think)
Angle 2 is 132 since it’s a vertical angle... i cant help you with the other 2 i’m sorry!!
Answer:
132x-8
Step-by-step explanation:
I think I might be wrong, but hopefully this is helpful, and yet I still find this confusing.
It's a simplification I don't know if you needed that.
