A patient needs a total dose of 50 grams of albumin. The pharmacy has 50 m
bottles of 25% Albumin in stock. How many bottles should the pharmacy
technician prepare to provide the required dose?
Answer : The number of bottles should the pharmacy technician prepare to provide the required dose are 4 bottles.
Step-by-step explanation :
As we are given that a patient needs a total dose of 50 grams of albumin and the pharmacy has 50 mL bottles of 25% Albumin in stock.
Now we have to determine the number of bottles should the pharmacy technician prepare to provide the required dose.
As,
The pharmacy has stock albumin = [tex]50mL\times \frac{25}{100}[/tex]
The pharmacy has stock albumin = 12.5 mL
So,
Number of bottles should the pharmacy technician prepare to provide the required dose = [tex]\frac{50}{12.5}[/tex]
Number of bottles should the pharmacy technician prepare to provide the required dose = 4
Therefore, the number of bottles should the pharmacy technician prepare to provide the required dose are 4 bottles.

For questions 1 – 6, find the area of the circle to the nearest hundredth.
Any help appriciated!
Step-by-step explanation:
The area of a circle is given by :
A = πr²
r is the radius of the circle
(4) Diameter = 22 cm
Since, radius = diameter/2
r = 11 cm
Now, area of the circle,
[tex]A=\pi \times (11)^2\\\\A=380.13\ cm^2[/tex]
(5) Diameter = 30 cm
Since, radius = diameter/2
r = 15 cm
Now, area of the circle,
[tex]A=\pi \times (15)^2\\\\A=706.85\ cm^2[/tex]
(6) Diameter = 4cm
Since, radius = diameter/2
r = 2 cm
Now, area of the circle,
[tex]A=\pi \times (2)^2\\\\A=12.56\ cm^2[/tex]
So, the area of circles 4,5 and 6 are 380.13², 706.85² and 12.56² respectively.
While on a trip, you notice that the video screen on the airplane, in addition to showing movies and news, records your altitude (in kilometers) above the ground.
As the plane starts its descent
(at time x = 0), you record the following data: Time, x (min.) Altitude, y (km)
12 0 10 8 16 16 18 4 110 12
If you were to graph these points on a graph, you would notice that the line that forms represents a linear function. What is the practical meaning of slope in this situation?
a. For every minute that passes, the airplane descends 1 kilometer.
b. For every minute that passes, the airplane ascends 1 kilometer.
c. For every 2 minutes that passes, the airplane descents 1 kilometer.
d. For every minute that passes, the airplane ascends 2 kilometers. C.
Answer:
a
Step-by-step explanation:

For every minute that passes, the airplane descends 1 kilometer. then option a is correct.
How to find the rate of change of a linear equation?Suppose that the considered linear equation is of the form
y=mx+c
Then, when we change x by 1 unit, then:
The rate of change is the slope. The formula for slope is
m = y2 - y1 / x2 - x1
Using the first two points, (0, 12) and (2, 10), we have
m = (10-12)/(2-0)
m = -2/2
m = -1
This means the plane descends 1 km per minute which means in 3 minutes' time, the plane descends 3 km.
Therefore, option a. For every minute that passes, the airplane descends 1 kilometer.

A department store is having a clothing sale. If a $35.00 pair of pants has a discount tag of 20% off, what is the sale price?
Answer:
$28.00
Step-by-step explanation:
You start with 35.00.
Now 10% of this is 3.5.
Multiply by 2 because it's 20%.
You get 7, so 7 is 20% of 35.00.
35.00 minus 7 is 28.00.
The pair of pants will be 28.00 dollars!

Solve for variable
if 50% is 7 what is 25%, 75%, and 100%
Answer:
100% = 14
75% = 10.5
25% = 3.5
Answer:
100% = 1475% = 10 1/250% = 725% = 3 1/2Step-by-step explanation:
50% if a number is also 1/2 of that number. So, we multiply 7 by 2 to get 14.
Now we know that we need to solve for 25%, 75%, and 100% of 14.
100% of a number is just that number, so 100% of 14 is 14.
To solve for 75% of 14, we multiply 3/4 by 14.
3/4 x 14/1 = 42/4 = 10 1/2
The final number to solve for is 25% of 14.
1/4 x 14/1 = 14/4 = 3 1/2
The natural market sells a 12-ounce jar of peanut butter for $3.96. They also sell bulk peanut butter for $5.50 per pound. The ____ has a cheaper unit rate.
Answer:
The Jar of peanut butter
Step-by-step explanation:
The easiest way to do this is to calculate price per ounce of each unit.
We'll assign the 12 ounce jar to the variable s and the bulk to the variable b.
First create an equation to find the values of each product per ounce.
Since the 12 ounce jar(s) sells for 3.96 we can say it is 3.96 for every 12 ounces, or s = 3.96/12oz.
Simplify this equation and you get s = 0.33 per ounce.
For b we need to convert pounds to ounces.
There are 16 ounces per pound so the equation we get is:
b = 5.50/16oz
Simplified we get:
b = about 0.34/oz
The smaller jar has a rate of $0.33/oz
The bulk has a rate of $0.34/oz
This means the answer is b. The jar of peanut butter has a cheaper unit rate.
Answer:
jar of peanut butter

f(x) =2x squared - 5x - 3 g(x) = x squared + 6x - 1 what is h(x), if h(x) = g(x) - f(x)
Answer:
-2x^2 + x^2 +11x +2
Step-by-step explanation:
f(x) = 2x^2-5x -3
g(x) = x^2 + 6x -1
h(x) = g(x) - f(x)
x^2 + 6x -1 - 2x^2 +5x +3
