Answer:
Volume = 204 m³
Step-by-step explanation:
The figure is a triangular prism
Volume of the triangular prism = ½ × a × c × h
Where,
a = 8 m
c = 5.1 m
h = 10 m
Plug in the known values and solve
Volume = ½ × 8 × 5.1 × 10
Volume = 4 × 5.1 × 10
Volume = 204 m³

Answer:
The unknown number is 12.
Step-by-step explanation:
Let the unknown number be 'x'
Given:
A number increased by 5 is equivalent to twice the same number decreased by 7.
So, 'x' increased by 5 means add 5 to 'x'. This gives 
Now, is equivalent to twice of 'x' decreased by 7.
Twice of 'x' means 2 times of 'x' which is 
'2x' decreased by 7 means subtract 7 from '2x'. This gives,
Now, and are equivalent meaning they are equal. So,
Therefore, the unknown number is 12.
7.65+22+5.95=35.6
420*35.6=148.52
420-148.52=270.48
You take home $270.48
