Answer: The required fraction = \dfrac18

Step-by-step explanation:

Let the required fraction = \dfrac{p}{q}

Given: Initial height = 192 inches

Height of ball after second bounce = \dfrac{p}{q}\times192

Height of ball after third bounce = \dfrac{p}{q}\times\dfrac{p}{q}\times192=192\dfrac{p^2}{q^2}

After the third bounce it is 3 inches off the ground.

So,

(\dfrac{p}{q})^2192=3\\\\\\(\dfrac{p}{q})^2=\dfrac{3}{192}\\\\(\dfrac{p}{q})^2=\dfrac{1}{64}\\\\(\dfrac{p}{q})^2=(\dfrac{1}{8})^2\\\\ \dfrac{p}{q}=\dfrac{1}{8}

Hence, The required fraction = \dfrac18

1.<br> A patient is told to force fluids to 3 L/day. How many mls should she drink?
Damm [24]

The patient should drink 3000 milliliter per day

<em><u>Solution:</u></em>

Given that a patient is told to force fluids to 3 liter per day

To find: Amount the patient should drink in milliliter

Use the conversion factor,

1 liter = 1000 milliliter

Now we have to find the amount the patient she drink in milliliter

Amount patient drinks in liter = 3 liter per day

Therefore, convert 3 liter to milliliter

3 liter = 1000 x 3 milliliter = 3000 milliliter

Thus the patient should drink 3000 milliliter per day
