Phantasy [73]

Answer:

The correct answer would be 0.85 liters.

It can be explained with the help of unit rate that is, when the rate is expressed as the quantity of 1 for example, 5 meter per second, 5 liters per day et cetera.

In this case, unit rate (liter per day) can be calculated by dividing the total amount of water used by total number of days.

Amount of water used in 28 days = 23.8 liters

The amount of water used in one day = \frac{23.8}{28}

It comes out to be 0.85 liters per day or 850 milliliter per day.

abruzzese [7]

Answer:

<em>6</em><em> </em><em>minutes</em>

EXPLANATION:

The brain can survive for up to about six minutes after the heart stops. The reason to learn cardiopulmonary resuscitation (CPR) is that if CPR is started within six minutes of cardiac arrest, the brain may survive the lack of oxygen.

How does a suspension form
