the wholesale price for a pair of shoes is $5.50. A certain department store marks up the wholesale price by 40%. Find the price

Furkat [3]

EXPLANATION

Price of shoes = $5.50

Markup= 40%

Let's call x to the unknown final price.

The markup percentage relationship is given by the following formula:

$\text{Markup =( }\frac{Selling\text{ Price}-\text{Cost Price}}{\text{Cost Price}})\cdot100$

Replacing terms:

$\text{40}=(\frac{x-5.5}{5.5})\cdot100$

Multiplying both sides by 5.5:

$40\cdot5.5=(x-5.5)\cdot100$

Dividing both sides by 100:

$\frac{40\cdot5.5}{100}=x-5.5$

Adding 5.5 to both sides:

$(\frac{40\cdot5.5}{100})+5.5=x$

Simplifyng the fraction:

$2.2+5.5=x$

Adding numbers:

$\text{7}.7\text{ = x}$

Switching sides:

$x=7.7$

Answer: The final price of the shoes in the deparment store is $7.7

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

PLZ HELP!!! 20 POINTS!!!<br><br> 1. Solve the system of equations by graphing: x + y = 3

sveticcg [70]

First you need to fix the equation in order to graph.
x + y = 3
Subtract x from both sides.
y = -1x + 3
Now graph.
(Whenever there is a variable by itself there is always a 1 in front of it.)

How do I do this problem

nata0808 [166]

All of the angles in a triangle equal 180° so if the first 2 angles are 60°, combined that equal 120°, leaving 60° left. X= 60°
