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
"Supplementary angles" means "angles add to 180 degrees"
So if x is one angle and 67 degrees is the other, and the two angles are supplementary, then x+67 = 180
The answer is choice A
Answer:
Cost of chip cookies = $17.5
Cost of ginger cookies = $19.5
Step-by-step explanation:
Assume;
Cost of chip cookies = c
Cost of ginger cookies = g
So,
Maya's sales = 8c + 12g = 374
.....Eq1
Carlo's sales = 2c + 4g = 113
.......Eq2
4 x eq2
So
8c + 16g = 452......Eq3
Eq 3 - Eq 1
4g = 78
g = 19.5
and
c = 17.5
Cost of chip cookies = $17.5
Cost of ginger cookies = $19.5
The horizontal axis represents variable A which means that variable A is ploted in the x-axis.
Each point is plotted (x, y) (i.e. the first number represents the value of variable A).
Therefore, the mean of variable A is
