On a standard reticulocyte preparation with new methylene blue, there are 100 cells counted with blue-stained granulofilamentous

DIA [1.3K]

Answer:

0.322 × 10¹² /L

Step-by-step explanation:

Data provided in the question:

Number of cells counted with blue-stained granulofilamentous material

i.e number of RET = 100

The red blood cells count = 3.22 × 10¹² /L

Hematocrit = 30%

Now,

RET% = [ [ Number of RET ] ÷ 1000 RBCs ] × 100%

= [ 100 ÷ 1000 ] × 100%

= 0.1 × 100%

= 10%

also,

Absolute reticulocyte count = ( %RET × RBC count ) ÷ 100

= [ 10 × 3.22 × 10¹² /L ] ÷ 100

= 0.322 × 10¹² /L

What is the volume of the cone below?

MrRa [10]

ANSWER

$112\pi \: {units}^{3}$

EXPLANATION

The volume of a cone is calculated using the formula:

$Volume = \frac{1}{3} \pi {r}^{2}h$

where r=4 units is the base radius of the cone.

and h=21 units is the vertical height of the cone.

We plug in the values to get;

$Volume = \frac{1}{3} \times \pi \times {4}^{2} \times 21$

$Volume = 112\pi \: {units}^{3}$

Find the length of BC, in simplest radical form.

zubka84 [21]

9514 1404 393

Answer:

BC = 16 +12√3

Step-by-step explanation:

In the attached, we see that ∆ABE is a 30°-60°-90° triangle with AB the short side and BE the hypotenuse. Then BE = 2·AB = 12√3.

EC is the side opposite AD in parallelogram ADCE, so is the same length, 16.

The length BC is ...

BC = EC +BE

BC = 16 +12√3

Ms. Etienne deposited $450 into an account that paid 5% interest compounded annually. She did not make any

Alexus [3.1K]

Answer:

$603.04

Step-by-step explanation:

The Compound Amout formula is A = P(1 + r)^t, where:

P is the principal (initial deposit), r is the annual interest rate as a decimal fraction, and t is the time period in years.

In this particular case, the Compound Amount is:

A = ($450)(1 + 0. 05)^6 = ($450)(1.34) = $603.04
