Answer:

$- \frac{19}{13}$

Step-by-step explanation:

$the \: multiplicative \: inverse \: of \: \\ - \frac{13}{19} = - \frac{19}{13}$

Product of a number and its multiplicative inverse should be equal to 1.

So,

$\bigg ( - \frac{13}{19} \bigg) \bigg ( - \frac{19}{13} \bigg)$

$= \frac{13}{19}\times \frac{19}{13}$

$=1$

Answer:

5 cm

Step-by-step explanation:

The volume (V) of a cuboid is calculated as

V = lbh ( l is length, b is breadth and h is height )

Here l = 20, h = 12, V = 1200 and b is to be found, thus

20 × b × 12 = 1200, that is

240b = 1200 ( divide both sides by 240 )

b = 5
