Answer:
7 in
Step-by-step explanation:
volume of a rectangular prism = width x height x length
width x length = area of the base
the sea shell box
200 = width x length x 5
width x length = 200/5 = 40cm^2
rock box
280 = 40in^2 x height
height = 280/40 = 7 in
The decay factor would be 1 minus the percent of decrease:
1-0.12 = 0.88
4+3+1+1+1+1+1 =12
4x3x1x1x1x1x1=12
Direct variations look like this (y = 3x_
Not direct variations (or inverse variations) look like this (y= 1/3x.) They are often in fraction form.
So, in your problem the direct variations are:
y= 3x
x = -1
-0.5x = y
y= 2.2x +7
y= 4
The non-direct variations are:
y = 2/7x
Is there a question for this problom, are we supoosed to find out if billy was thinking right or was he wrong.
