The ratio strength of the final product is 1:0.4.

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

4.8 is now added after finding the sum of 90 and 10.

Step-by-step explanation:

a. It is b. Permutation

b. Using permutation, the number of different codes is 3024 passcodes.

Permutation is the total number of ways of arranging n different objects in x ways ⁿPₓ  = n!/(n - x)! while combination is the total number of ways of selecting n objects x at a time ⁿCₓ = n!/x!(n - x)!

a. Since Sara is setting a new code for her garage. The key pad has the numbers 0-9 to choose from, and she needs to set a 4-digit passcode. Since no digit is to be repeated, it is a permutation since in permutation, we are looking for differnt arrangemnets of the objects.

So, it is b. Permuation

b. Since Sara the key pad has the numbers 0-9 to choose from, and she needs to set a 4-digit passcode and no digit is to be repeated. We have 9 digits permuted or arranged in 4 ways. So, our permutation is ⁹P₄ = 9 × 8 × 7 × 6

= 3024 passcodes

So, the number of different codes is 3024 passcodes.

Step-by-step explanation:

Note that both terms, 3x and -30, have a 3 in common. This is called the greatest common factor, or g.c.f.

The g.c.f. of 3x and -30 is 3. So we divide both 3x and -30 by 3, and obtain

a) 2 square.

With speed = 10 m/s, the rope will hit ground after 3.36 seconds.

Speed is a measure of how fast an object is moving, usually measured in units of distance per unit time, such as meters per second (m/s) or kilometers per hour (km/h). It is a scalar quantity, meaning it only has magnitude and no direction.

Mathematically, speed is defined as the distance an object travels per unit time. The formula for calculating speed is:

Speed = Distance / Time

where Distance is the distance traveled by the object, and Time is the time taken to cover that distance.

Now,

To find when the rope will hit the ground, we can use the kinematic equation:

y = vi * t + (1/2) * a * t²

where:

y = 50 m (the height of the cliff)

vi = 10 m/s (the initial velocity of the rope)

a = 9.8 m/s² (the acceleration due to gravity, acting downward)

t = time it takes for the rope to hit the ground

We can solve for t by setting y=50 and solving for t:

50 = 10t + (1/2) * 9.8 * t²

50 = t(10 + 4.9t)

t = 50/14.9=3.36 s

Therefore, the rope will hit the ground after 3.36 seconds.

The final value is:

f(-5) = (-5)^2 = 25.

f(-5) = (-5)^2 - 1 = 24.

f(-5) = (-5)^2 + 1 = 26.

We can solve this problem by using the fact that the derivative of a function gives us the slope of the tangent line at any point. We can then use this information to find the equation of the function that satisfies the given derivative and the additional information about the function's values at certain points.

A) To find f(-5) if f(0)=0, we need to integrate the derivative f'(x)=2x with respect to x, since integration is the inverse operation of differentiation.

∫f'(x)dx = ∫2xdx = x^2 + C

where C is the constant of integration.

Since f(0)=0, we can find C by substituting x=0:

f(0) = 0^2 + C = 0

C = 0

Thus, the equation of the function is:

f(x) = x^2

So, f(-5) = (-5)^2 = 25.

B) To find f(-5) if f(1)=0, we can use the same method:

∫f'(x)dx = ∫2xdx = x^2 + C

Since f(1)=0, we can find C by substituting x=1:

f(1) = 1^2 + C = 0

C = -1

Thus, the equation of the function is:

f(x) = x^2 - 1

So, f(-5) = (-5)^2 - 1 = 24.

C) To find f(-5) if f(-4)=17, we can again use the same method:

∫f'(x)dx = ∫2xdx = x^2 + C

Since f(-4)=17, we can find C by substituting x=-4:

f(-4) = (-4)^2 + C = 17

C = 1

Thus, the equation of the function is:

f(x) = x^2 + 1

So, f(-5) = (-5)^2 + 1 = 26.

Where x is the time in days and A is the initial population.

Here we know that the initial populationis 12 rabbits, then the function is:

P(x) = 12*(1.45)^(x/10)

And the population after 90 days is:

P(90) = 12*(1.45)^(90/10)

Answer:

original fraction = \(\frac{4}{5}\)

Step-by-step explanation:

let the denominator of the fraction be x then the numerator is x - 1 , so

original fraction is

\(\frac{x-1}{x}\)

if 1 is added to the numerator and 5 to the denominator , then fraction is

\(\frac{-1+1}{x+5}\) = \(\frac{x}{x+5}\)

equate this to \(\frac{1}{2}\)

\(\frac{x}{x+5}\) = \(\frac{1}{2}\) ( cross- multiply )

2x = x + 5 ( subtract x from both sides )

x = 5

then original fraction is

\(\frac{x-1}{x}\) = \(\frac{5-1}{5}\) = \(\frac{4}{5}\)

Answer:

Below

Step-by-step explanation:

Original fraction   (x-1) / x          <====given   (use in final step below)

Altered fraction   (x-1  +1) / (x+5)  = 1/2     <====solve this  for 'x'

                                   x / (x+5) = 1/2      cross multiply

                                        2x = x+5

97.5% of American women have shoe sized less than 11.19 according to standard deviation of 1.49 .

What is standard deviation?

It is a measure of how spread out numbers are. It is the square root of the Variance, and the Variance is the average of the squared differences from the Mean.

Main Body:

Here, we want to use the empirical rule to find the percentage of women with shoe sizes less than 11.19

The first thing we shall do here is to find the z-score

Mathematically, that will be calculated using the formula;

z = (x-mean)/SD

z = (11.19-8.21)/1.49

z = 2

We can see that the given value is 2 standard deviation away to the right of mean

So, we want to get the percentage that is between the mean and two standard deviations away from it using the empirical rule

So according to the empirical rule

The percentage will be

A decrease in the price of cotton can have positive effects on the affordability and availability of socks in the market, benefiting consumers by potentially offering lower prices and a wider range of choices.

If the price of cotton falls in the market for a bag of socks, it is likely to have an impact on the overall cost and availability of socks. Cotton is a common material used in the production of socks, and its price plays a significant role in determining the cost of manufacturing.

When the price of cotton falls, it reduces the cost of raw materials for sock manufacturers. As a result, manufacturers may experience lower production costs. This can lead to several outcomes:

1. Decrease in sock prices: With lower production costs, manufacturers have the option to reduce the prices of socks to attract customers. This can result in more affordable socks for consumers, making them more accessible.

2. Increase in sock supply: Lower production costs may incentivize manufacturers to increase their sock production. As a result, the supply of socks in the market could rise, leading to a greater availability of socks for consumers.

3. Potential for improved quality or additional features: Manufacturers may choose to invest the cost savings from lower cotton prices into enhancing the quality of socks or adding extra features. This can result in socks with improved durability, comfort, or design, providing more options for consumers.

It's important to note that the impact of falling cotton prices on sock prices and availability may also depend on other factors, such as production and distribution costs, market competition, and consumer demand. Additionally, the extent to which the price reduction in cotton translates into lower sock prices may vary among different brands and retailers.

Overall, a decrease in the price of cotton can have positive effects on the affordability and availability of socks in the market, benefiting consumers by potentially offering lower prices and a wider range of choices.
