The ratio strength of the final product is 1:0.4.
What is ratio strength?One technique to indicate concentration is through ratio strength, which uses a ratio to characterize drug concentration. In this context, concentration is defined as the quantity of a solute that makes up one unit in the whole volume of a solution or combination. You should be an expert in ratio strength calculations as a pharmacy student. Ratio strength uses a ratio to describe the medication concentration. So, what it implies is, you have one unit of solute contained in the complete amount of preparation and so generally your ratio strength is expressed as one is to something. In the case of a weight-in-weight, volume-in-volume, or weight-in-volume situation, you would interpret a ratio of 1:2,000 differently.
Drug strength = 800mg
whole volume =2ltrs
The ratio of the solution in 1 ltr is = 400 mg
The ratio strength of the solutions is = 1:0.4

If 0.25 cm represents 5 feet on a blueprint, what is the actual length of a room that is 8.5 inches long?
In proportion , 13 ft is the actual length of a room.
What in mathematics is a proportion?
A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)
0.25 inches 8.5 inches
---------------- = --------------
5 ft x ft
Using cross products
0.25x = 8.5 * 5
Divide each side by 0.25
0.25x/0.25 = 8.5 * 5/0.25
x = 13
x = 13 ft

The recommended mass m of a baseball is 145 grams. The actual mass is allowed to vary by up to 2 grams. What are the minimum and maximum allowed baseball masses?
The minimum and maximum allowed baseball masses are 143 grams and 147 grams
What are the minimum and maximum allowed baseball masses?The given parameters are
Mass = 145 grams
Vary = 2 grams
This means that the allowed baseball masses are
Allowed baseball masses = Mass ± Vary
This gives
Allowed baseball masses = (145 - 2, 145 + 2) grams
Evaluate
Allowed baseball masses = 143 grams, 147 grams
Hence, the minimum and maximum allowed baseball masses are 143 grams and 147 grams

What is the length of QN
The length between the two points is 9.2 units.
Given points are:
Q(1,₋5)
P(₋5,2)
Let the two points be denoted as
Q(1,₋5) as (x₁,y₁)
P(₋5,2) as (x₂,y₂)
Distance between two points is calculated as:
d = √(x₂ ₋ x₁)² ₊ (y₂ ₋ y₁)²
d = √(₋5 ₋ 1)² ₊ (2 ₋ (₋5))²
d = √(₋6)² ₊ (7)²
d = √36 ₊ 49
d = √85
d = 9.2

The cost of bananas varies directly with the number of pounds bought. If 6 pounds
cost $5.22, find the cost of 3 pounds.
Answer:
$2.61
Step-by-step explanation:
So, We have $5.22 for 6 pounds of Bananas.
If we need to find the cost for 3 pounds, we would divide $5.22 by 2 because 6/2=3
In order to do this, we need to turn 5.22 into a whole number, so we multiply by 100
5.22*100=522
Now we divide
522/2 = 261
Now we divide 261 by 100, since we multiplied by 100 earlier.
261/100 =2.61
So our answer is $2.61 for 3 pounds of bananas .
Hope this helps! ^^

What is the remainder when f(x) = x4 + 7x3 + 17x2 + 20x is divided by x2 + 4?
a
\large x^2+13x+7+\frac{-52}{x^2+4}
b
\large x^2+7x+\frac{13x-8}{x^2+4}
c
\large x^2+7x+13+\frac{5x-52}{x^2+4}
d
\large x^2+1+\frac{1}{x^2+4}
The reminder by dividing f(x)= x⁴ + 7x³ + 17x² + 20x is divided by x² + 4 is x² + 7x + (-13x² - 8x)/(x² + 4) so none of the given option is correct.
What is a number system?The number system is a way to represent or express numbers.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
Given the dividend f(x)= x⁴ + 7x³ + 17x² + 20x and diviser x² + 4
The first time it will go to x²
Then,
Quotient = x²
Remainder = 7x³ - 13x²
The second time goes to 7x
Quotient = 7x
Remainder = -13x² - 28x
The third time it is not divisible so (-13x² - 8x)/(x² + 4) will be the reminder.
Together it is x² + 7x + (-13x² - 8x)/(x² + 4).
Hence "The reminder by dividing f(x)= x⁴ + 7x³ + 17x² + 20x is divided by x² + 4 is x² + 7x + (-13x² - 8x)/(x² + 4)".

Suppose that a single die with 6 sides (numbered 1, 2, 3, ... , 6) is rolled twice. what is the probability that the sum of the two rolls equals 5 ?
The probability that the sum of the two rolls equals 5 is 1/16.
What is probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favorable outcomes / Number of sample
Given a single die with 8 sides (numbered 1, 2, 3, ..., 8) is rolled twice, the total outcome will be:
Total outcome = 8^2
Total outcome = 64
For the sum of two rolls, the expected outcome will be:
E = {(1, 4), (4, 1), (3, 2), (2, 3)}
n(E) = 4
Pr(sum of the two rolls is 5) = 4/64
Pr(sum of the two rolls is 5) = 1/16
Hence the probability that the sum of the two rolls equals 5 is 1/16

How many pairs of parallel lines are in the flipped shape?
The flipped shape has a pair of parallel line
What are parallel lines?A pair of line is said to be parallel lines when the lines tend to maintain equal distance apart and never intersect at any point. such lines has peculiar properties and are useful in mathematics.
Since a pair of parallel line do not intersect their is not angle between them.
What happens when a shape is flipped ?Flipping a shape will change the position of the flipped shape to a new one. This activity does not add to the size of a shape or to the property of the shape.

Use the roster method to write the given set the set of integers x that satisfy 2x-1= -13
The only set of elements that satisfied the equation 2x-1= -13 is {-6}.
What is a set?A set is a combination of specific quantities in which the meaning of each variable must be the same.
For example {1,2,3,4,5,6...} is a set of natural numbers in which each variable is representing a natural number so the overall meaning is the same among all.
Another example could be a set of whole numbers like that.
Given the equation,
2x-1= -13
By taking -1 right-hand side
2x = -13 + 1 = -12
By dividing 2
x = -6

The monthly payment will be $1454.06048
You can calculate the Car Loan EMI Amount with the help of the mathematical formula: EMI Amount = [P x R x (1+R)^N]/[(1+R)^N-1] , where P, R, and N are the variables. This also means that the EMI value will change, each time you change any of the three variables. Let’s discuss these three variables in detail.
‘P’ stands for the Principal Amount. It is the original loan amount given to you by the bank on which the interest will be calculated.
‘R’ stands for the Rate of Interest set by the bank.
N is the number of years given for the repayment of the loan. As you must pay the EMIs each month, the duration is calculated in the number of months.
Here , P=$50000,R=3/12/100=0.0025,N=36 Months.
