mash [69]

Answer:

20%

Step-by-step explanation:

To find this, set up a ratio of percent over 100 equals is over of. Is being 32 and of being 160.

$\frac{32}{160}$ = $\frac{x}{100}$

Then, cross multiply. Multiply 32 by 100 before dividing by 160 in order to get the final answer of 20%.

32 x 100 = 3200

3200/160 = 20

Hope this helps!

Evaluate the following when $a = 3$, $b = \frac14$, and $c = 5$: \[ \frac{b^{-1}}{ca^{-1} - ac^{-1}}. \] Thank you so much!

pickupchik [31]

$\dfrac{b^{-1}}{ca^{-1}-ac^{-1}}=\dfrac{\frac1b}{\frac ca-\frac ac}$

Multiply the numerator and denominator by $ac$ :

$\dfrac{\frac1b}{\frac ca-\frac ac}\cdot\dfrac{ac}{ac}=\dfrac{\frac{ac}b}{c-a}$

Since $b=\frac14$ , we have $b^{-1}=\frac1b=4$ . So substituting the values of a, b, and c gives us

$\dfrac{\frac{ac}b}{c-a}=\dfrac{3\cdot5\cdot4}{5-3}=\dfrac{60}2=\boxed{30}$
