3 is the value of x  which makes the given inequality true.

A relationship that compares two numbers or other mathematical expressions in an unequal way is known as an inequality in mathematics.  On the number line, it is most frequently used to compare the sizes of two numbers. To represent various types of inequalities, a variety of notations are used:

A < B, such as a, denotes that an is greater than b.

A > B indicates that an is greater than b.

A and b are not equivalent in either scenario. As a result, an is strictly less than or strictly greater than b, and these relationships are referred to as strict inequalities. Equivalence is disregarded.

Answer:

  75 mg

Step-by-step explanation:

You want the dose for a 72 pound person at the rate of 2.5 mg/kg.

We multiply by conversion factors that cancel unwanted units, leaving the units we want.

At the end of the unit conversion, we need to determine if the calculated dose is closer to 75 mg or 100 mg. It is less than 87.5 mg, so is closer to 75 mg.

  [tex]\dfrac{2.5\text{ mg}}{\text{kg}}\times(72\text{ lb})\times\dfrac{0.453\text{ kg}}{\text{lb}}=2.5\times72\times0.453\text{ mg}\approx81.54\text{ mg}\\\\\approx\boxed{75\text{ mg}}[/tex]

Additional comment

We found the nearest 25 mg dose by dividing by 25 mg, and rounding the 3.26 dose result to 3 doses of 25 mg each.

Answer:

y = 3x + 2

Step-by-step explanation:

In the equation [tex]y = mx + b[/tex], m represents the slope, and b represents the y-intercept. To write the equation in this form, we must substitute m and b into this equation.

. . . . . . . . . . . Finding "b"

The y-intercept is another name for the y-value when the x- value = 0. So, we need to look at the table and find the y-value for when x = 0.

⭐ y = 2 when x = 0. Thus, b = 2.

. . . . . . . . . . . Substitute "b" into the equation

 y = mx + 2

. . . . . . . . . . . One way to find "m"

 m, your slope, can be found using the slope formula: [tex]m = \frac{y__2 - y__1}{x__2 - x__1}[/tex], where [tex](x__1, y__1)[/tex] and [tex](y__2, y__1)[/tex] are coordinates that you are given.

I am going to choose the coordinates (0,2) and (1,5), but you can choose any other 2 coordinates from the table.

m = (5 - 2)/(1-0)

m = 3/1

⭐ m = 3

. . . . . . . . . . . Another way to find "m"

  m, your slope, can be found by substituting a coordinate that you are given into your equation with b already found.

y = mx + 2

I am going to use the coordinate (1,5), but you can choose another coordinate from the table if you'd like.

-2 + 5 = 1(m) + 2 -2

⭐ 3 = m

. . . . . . . . . . . Substitute "m" into the equation

 y = 3x + 2

Answer:

(0,2)

2 = b

(1,5)

5 = m + b

(2,8)

8 = m(2) + b

(3,11)

11 = m(3) + b

(4,14)

14 = m(4) + b

The time required to fill the pool by using both the hoses is 4/5 hours.

Algebra is the study of mathematical expressions, in which letters and other generic symbols are used to represent numbers and quantities in formulas and equations.

Given that,

Time taken by hose A to fill 3/4 of the pool = 1 hour.

And time taken by hose B to fill the 2/4 of the same pool = 1 hour.

From the given information,

Time taken by hose A to fill the whole pool = 1 x (4/3) = 4/3 hours

And time take by hose B to fill the whole pool = 1 x (4/2) = 1 x 2 = 2 hours.

The LCM of 4/3 and 2 is 4, which can be considered as total capacity of pool.

The efficiency of hose A = 4/(4/3) = 3

The efficiency of hose B = 4/2 = 2

The graph of the inverse function of f(x) is given by the image shown at the end of the answer.

The function in this problem is defined as follows:

f(x) = 1/x + 4.

The definition of the function is given because of the asymptotes as follows:

To obtain the inverse of a function y = f(x), first the variables y and x are exchanged, as follows:

x = 1/y + 4.

Then the variable y has to be isolated, as follows:

1/y = (x - 4).

The person whose purple paint will be bluer is Skylar.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

In this case, Hassan mixes 1 cup of blue paint and 3 cups of red paint. The percentage for blue paint will be:

= 1 / (1 + 3) × 100

= 1/4 × 100

= 25%

Skylar mixes 5 cups of blue paint and 3 cups of red paint. The percentage for blue will be:

= 5 / (5 + 3) × 100

Given Dr. Sparrow's design, his study is best able to overcome the issue of causality, as well as the issue of some potential third variables.

By using a multivariate design, Dr. Sparrow is able to examine the relationships between multiple variables simultaneously, which can help to identify the potential influence of each variable on the outcome of interest (marital satisfaction in this case). This can help to establish a causal link between the variables if one is present, as it allows for the examination of multiple variables at the same time, rather than just two variables as in a simple bivariate design.

Additionally, by controlling for other potential confounding variables, Dr. Sparrow is able to account for the potential influence of these variables on the relationship between income and marital satisfaction, which helps to establish a more robust understanding of the potential causal link between these two variables.

Answer:

The length of w is 50.0 cm.

Step-by-step explanation:

To find the length of w, we can use the Law of Sines:

w / sin V = x / sin X

Plugging in the values given in the question, we get:

w / sin 16° = 77 cm / sin 74°

Solving for w, we get:

w = 50.0 cm

Rounding to the nearest 10th of a centimeter, we get:

w = 50.0 cm

Therefore, the length of w is 50.0 cm.

Answer:

w=80.1 cm

Step-by-step explanation:

According to the Law of Sines:

[tex]\frac{\sin(\alpha)}{a}=\frac{\sin(\beta)}{b}=\frac{\sin(C)}{c}[/tex]

For this problem, let

[tex]\alpha[/tex]=∠X=74°

[tex]\beta[/tex]=∠V=16°

Since the sum of the angle measures in all triangles must equal 180°, ∠w must equal 90°.  So, for this problem, let

C=∠W=90°.

And let

a=x=77 cm

c=w

So,

[tex]\frac{\sin(74)}{77\ cm}=\frac{\sin(90)}{w}\\0.01248\ cm=\frac{1}{w}\\w=80.1\ cm[/tex]

This can be checked using the Law of Sines with all values entered.

To find b, use the Pythagorean Theorem:

[tex](80.1\ cm)^2=(77\ cm)^2+b^2\\6416.01\ cm^2=5929\ cm^2+b^2\\487.01\ cm^2=b^2\\b=22.07\ cm[/tex]

So,

[tex]\frac{\sin(74)}{77\ cm}=\frac{\sin(16)}{22.07\ cm}=\frac{\sin(90)}{80.1\ cm}\\0.0125\ cm=0.0125\ cm=0.0125\ cm[/tex]

Polynomials can be divided using long division method and

synthetic division method.

What is a polynomial?

Algebraic expressions which are made up of coefficients and variables are called polynomials.

For example x + 3, 3y² -10, r³, t³ + 4t³ - 80, etc.

Polynomials can be classified as monomials, binomials and trinomials based upon the number of terms present.

According to the given question:

There are two methods that can be employed while dividing two given polynomials:

1. Long Division Method

The long division method is the most frequent and general method for dividing polynomials by binomials or any other form of polynomials.

Steps:

Step 1: Divide the dividend’s first term by the divisor’s first term, and use it as the quotient’s first term.

Step 2: Multiply the divisor, then place the product beneath the dividend

Step 3: To make a new polynomial, subtract.

Step 4: Use the new polynomial obtained after subtraction to repeat the operation.

2. Synthetic Division Method

It is a technique for dividing a polynomial by a linear binomial using only the coefficient values. We write the polynomials in standard form from the greatest degree term to the lowest degree term in this manner.

Steps:

Step 1: Ensure that the divisor is in the form of x − k.

Step 2: Write the dividend coefficients on the right and k on the left to set up the division.

Step 3: Now, reduce the coefficient of the dividend’s highest degree term to zero.

Step 4: Multiply k by that leading coefficient and write the product below the second coefficient on the dividend’s left side.

Step 5: Multiply the numbers in the second column.

Step 6: Multiply k by the number obtained in step 5 and write the result in the next column to the right.

Step 7: Finally, we’ll write the final solution, which will be one degree below the dividend.

The quadrilateral that has vertices (2,0), (0,-2), (-2,4) and (-4,2) is option

b. rectangle

To determine the special quadrilateral that is formed by connecting the midpoints of the sides of the quadrilateral with vertices (2,0), (0,-2), (-2,4) and (-4,2), we can find the midpoints of each side and then determine the shape formed by these points.

The midpoint of a line segment is the point that is exactly halfway between the two endpoints of the line segment. To find the midpoint of a line segment, we can take the average of the x-coordinates of the endpoints and the average of the y-coordinates of the endpoints.

We can find the midpoint of the side between (2,0) and (0,-2) by taking the average of the x-coordinates (2 and 0) and the average of the y-coordinates (0 and -2), which gives us the point (1,-1).

We can find the midpoint of the side between (0,-2) and (-2,4) by taking the average of the x-coordinates (0 and -2) and the average of the y-coordinates (-2 and 4), which gives us the point (-1,1).

We can find the midpoint of the side between (-2,4) and (-4,2) by taking the average of the x-coordinates (-2 and -4) and the average of the y-coordinates (4 and 2), which gives us the point (-3,3).

We can find the midpoint of the side between (-4,2) and (2,0) by taking the average of the x-coordinates (-4 and 2) and the average of the y-coordinates (2 and 0), which gives us the point (-1,1).

What are supplementary angles ?

Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°. Similarly, complementary angles add up to 90 degrees.

Given : difference between the measure of two supplementary angles is 92 .

Let the two angles be x and y then , x - y = 92

Since , supplementary angles add up to 180 degrees

x + y = 180 (say 1)

x - y = 92(say 2)

---------------add(1 & 2)

2x = 272

x = 272/2

x = 136 <=== this is one angle

x + y = 180

136 + y = 180
