There is a drug order for 75 mg of drug.The drug is available in 30-mg scored tablets. How many tablets should be administered?

rosijanka [135]

Answer:

Assuming that tablets can be devided, $2\frac{1}{2}$ tablets are needed.

Assuming that tablets cannot be devided, $3$ tablets are needed.

Step-by-step explanation:

To find the total number of tablets that covers the order, we can divide the order total mg over each tablet mg.

$\frac{TotalOrderMg}{SingleTabletMg} = \frac{75 mg}{30 mg} = 2.5 mg$

Assuming that tablets can be devided, we can express the previous result in fractions

$2.5 = \frac{25}{10} = \frac{5}{2} = \frac{4}{2} + \frac{1}{2} = 2\frac{1}{2}$

Assuming that tablets cannot be devided, we need to cover 2 tables and a half, then we will need 3 tables.

3. Find the volume of the pyramid.

Gnoma [55]

Answer:

$916.11\:ft^{3}$

Step-by-step explanation:

Volume of the hexagonal pyramid = $1/3\times (area\: of \: hexagonal\:base)\times height$

Here sides of hexagonal base = 9 ft

So, Area of hexagon = $6\times \frac{\sqrt{3} }{4} a^{2}$

$6\times \frac{\sqrt{3} }{4} \times 9 \times 9$

$= 210.5$

Height is given, 13 ft

So, volume = $1/3\times 210.5\times 13$

$= 916.11\: ft^{3}$

Please I need hep, get free brainly :D

padilas [110]

Step-by-step explanation:

Formula:

$\boxed{a = 3.14(r)^{2} }$

r represents the radius.

The radius is 1/2 of the diameter.

Since 1/2 of 16 is 8, 8 is our radius.

Substitute:

$a = 3.14(8)^{2}$

Solve:

$a = 3.14(64)$

$a = 200.96in^{2}$
