krok68 [10]

Answer:

you need to convert pounds to kilograms. 196 pounds is 88.904 kilograms. The directions tell you that 20 milligrams of the drug is to be administered for each kilogram of a person's weight. Now you need to multiply 88.904 by 20. That should give you 1778.08 milligrams of lincomycin. You would then mix 250 cc's of saline solution to the 1778.08 milligrams of lincomycin; but I think its just asking you how much lincomycin to administer.

at what rate per minute should the 250 cc solution be adminstered

Two pyramids are similar with a ratio of surface areas of 25:36. Find the volume of the larger pyramid given that the first has
ki77a [65]

Answer:

432m^3

Step-by-step explanation:

The computation of the volume of the larger pyramid is shown below:

Let us assume the volume of the larger pyramid be x

Given that

The ratio of two pyramids is 25:36

We can say that

The Ratio of side = (The ratio of surface area)^\frac{1}{2} = \frac{5}{6}

Now

ratio of volume = (ratio of side)^3 =  \frac{5^{3}}{6^{3}} = 125 : 216

Based on the above information, the calculation is as follows

\frac{125}{216} = \frac{250}{x}

So,

x = \frac{250 \times 216}{125}

= 432m^3
