A tub is filled with 18000 cm3 of water. It loses one-tenth of its water every 12 hours. What volume of water would be remaining

Lina20 [59]

Answer:

0 cm³

Step-by-step explanation:

the lost of water =

(5×24)/12 x 1/10 × 18000

= 10/10 × 18000 = 18,000 cm³

so, the remaining water in the tub=

18,000 - 18,000 = 0 cm³

(the tub is empty)

a stack of boards is 24 inches high. Each board is 3/8 of an inch thick. How many boards are in the stack?

meriva

To answer this we need to divide 24 by 3/8.

First we need to convert 24 to a fraction.

$\frac{24}{1}$

When dividing fraction, multiply the first fraction by the reciprocal of the second fraction. (A reciprocal is an upside down fraction)

$\frac{24}{1} * \frac{8}{3} = \frac{192}{3}$ (simplify:) 64

The answer is 64
