These lines are perpendicular because y = -6 is a horizontal line with a slope of 0 and x = 6 is a vertical line with an undefined slope
Answer:
Your answer is: No solution
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Step-by-step explanation:
Hope this helped : )
I think it would stay the same as t^3 cannot be factorised nether can the 3t or the 2 so it would be the same
<span>l = length
w = width
h = height
SA =
2lw + 2wh + 2lh.
V = lwh.
Write an expression for the ratio of surface area
to volume:
SA / V = [</span><span><span> 2lw + 2wh + 2lh] / </span>lwh
SA / V = 2lw / lwh + 2wh / lwh + 2lh / lwh
SA / V = 2/h + 2/l + 2/w
Choose an appropriate length, width, and
height for your package so that it can fit the product you are shipping.
Using these dimensions, what is the ratio of surface area to volume?
I will work with an hypothetical figure where you have , l, w and the volume.
I suppose you know the volume, because it is the amount of product you need to pack. Make V = 1000 cm^3, l = 10 cm and w = 5 cm.
Wtih two dimensions and the volumen you can find the other dimension.
V = lwh = 1000 cm^3 => h = 1000 cm^3 / (lw) = 1000 cm^3 / (10 cm * 5 cm)
h = 1000 cm^3 / (50 cm^2) = 20 cm
Now you have the three dimensions to pack 1000 cm^3 of your product:
l = 10 cm
w = 5 cm
h = 20 cm
And the ratio of surface area to volume is:
SA / V = 2/h + 2/l + 2/w = 2/(20cm) + 2/(10cm) + 2/(5cm) = 0,7 (cm)^-1
