This is the concept of volumes of solid materials, the volume of lumber is given by:
volume=length*width*height
Volume=2*8*12=192in^3
The number of times a board whose volume is 144 in^3 would fit into the lumber will be given by:
[volume of lumber]/[volume of board]
=192/144
=1 1/3=4/3 times

Step-by-step explanation:
Answer:
1/27
Step-by-step explanation:
If (-3, y) lies on the graph of y = 3^x, then we can find y by filling in the given x and calculating y
They gave us that x is -3 (the first number in an ordered pair is the x).
y = 3^x
y = 3^(-3)
y = 1/(3^3)
**You "fix" a negative exponent by pushing across a fraction bar; that changes the sign of an exponent**
y = 1/27
Because3^3 is 3×3×3 is 27
