Original bread is 10 X 12.5 X 2. so if you cut pieces 2 X 2.5X 2 you would take 1o inches divided by 2 inches = 5 pieces (long). 12.5 inches divided by 2.5 inches wide = 5 pieces (wide). The 2 inches high cancels itself out because the bread is 2 inches high to begin with. Therefore 5 X 5 = 25 or 25 total pieces of banana bread at 2" x 2.5" x 2".

Andrej [43]

Answer:

The Poisson's ratio for the material is 0.0134.

Step-by-step explanation:

The Poisson's ratio ( $\nu$ ), no unit, is the ratio of transversal strain ( $\epsilon_{t}$ ), in inches, to axial strain ( $\epsilon_{a}$ ), in inches:

$\nu = -\frac{\epsilon_{t}}{\epsilon_{a}}$ (1)

$\epsilon_{a} = l_{a,f}-l_{a,o}$ (2)

$\epsilon_{t} = l_{t,f}-l_{t,o}$ (3)

Where:

$l_{a,o}$ - Initial axial length, in inches.

$l_{a,f}$ - Final axial length, in inches.

$l_{t,o}$ - Initial transversal length, in inches.

$l_{t,f}$ - Final transversal length, in inches.

If we know that $l_{a,o} = 61.2\,in$ , $l_{a,f} = 61.235\,in$ , $l_{t,o} = 2.7\,in$ and $l_{t,f} = 2.69953\,in$ , then the Poisson's ratio is:

$\epsilon_{a} = 61.235\,in - 61.2\,in$

$\epsilon_{a} = 0.035\,in$

$\epsilon_{t} = 2.69953\,in - 2.7\,in$

$\epsilon_{t} = -4.7\times 10^{-4}\,in$

$\nu = - \frac{(-4.7\times 10^{-4}\,in)}{0.035\,in}$

$\nu = 0.0134$

The Poisson's ratio for the material is 0.0134.

What points are solutions to the equation 3x-4y-8=12

ikadub [295]

Answer:

x = 6.67

Step-by-step explanation:

Rewrite the equation:

-4y = -3x +20

y = $\frac{3}{4} x-5$

Find where y = 0

0 = $\frac{3}{4} x -5$

5 = $\frac{3}{4} x$

x = 6.67

Hope it helps! (:
