Find the volume of a box that is 2 in x 4 in x 3 in.
A) 2 ft2
B) 2 ft3
C) 24 in2
D) 24 in3

To make a line plot, plot all the numbers you see. Then plot how many of each number you see. For example, there are 4 one's in the data, so draw 4 x's above 1. I hope this helps!

The answer is:

- First inequality:  The fourth number line.

- Second inequality: The second number line.

- Third inequality: The first number line.

- Fourth inequality: The third number line.

To be able to match each inequality to the number line that represents its solution, we need to solve each inequality.

So, solving we have:

- First inequality:

[tex]\frac{7x}{9}>-\frac{14}{3}\\\\x>-\frac{14}{3}*\frac{9}{7}>-\frac{126}{21}>-6 \\\\x>-6[/tex]

Therefore, the solution for the first inequality is the x greaters than 6, and the solution matchs with the fourth number line.

- Second inequality:

[tex]-\frac{75x}{4}>\frac{225}{2}\\\\\frac{75x}{4}<-\frac{225}{2}\\\\x<-\frac{225}{2}*\frac{4}{75}<-6[/tex]

Therefore, the solution for the first inequality is the x less than 6, and the solution matchs with the second number line.

- Third inequality:

[tex]\frac{x}{4}\leq -\frac{3}{2}\\\\x\leq -\frac{3}{2}*4\leq -\frac{12}{2}=-6[/tex]

Therefore, the solution for the first inequality is the x less or equals than 6, and the solution matchs with the first  number line.

- Fourth inequality:

[tex]\frac{2x}{3}>-\frac{16}{3}\\\\x>-\frac{16}{3}*\frac{3}{2}>-\frac{48}{6}>-8\\\\x>-8[/tex]

Therefore, the solution for the first inequality is the x greater than 6, and the solution matchs with the third number line.

The student's question pertains to a survey on students' opinions about a new school mascot. The survey results showed varying levels of support and opposition, which are crucial for decision-making in educational policy. This demonstrates the real-world application of mathematics in understanding public opinion through statistics.

The student's question deals with a survey conducted by student government members to understand the school community's stance on the new school mascot. This survey follows a systematic sampling method by asking every 15th student entering the school. The outcome showed that 57% oppose, 37% are in favor, and 6% have no opinion regarding the new mascot. Such a poll is useful for making decisions related to public policy and ensuring that actions consider community preferences.

Another key component is understanding the methodology behind this survey. If we consider a similar scenario where 600 students are surveyed with 480 opposing new legislation (as mentioned in one of the examples), we could calculate the percentage opposing the legislation and use this to propose actions or influence decision-making processes regarding school policies.

In the context of educational institutions, conducting polls or surveys is a practical way to involve student bodies in decision-making processes, reflecting a democratic practice in school governance. This kind of statistical analysis forms a crucial part of mathematics in the real world, particularly within the fields of statistics and probability.

The answer is:

The third option,

[tex]x^{2}+mx+m=(x+2)^{2}[/tex]

We are looking for an equation that establishes a relationship between the perfect-square trinomial and the givens notable products.

So, we are looking for a notable product that gives us a value of "m" that is the coefficient of the linear term (x) and it's also the constant term.

- Trying with the two first options, we have:

[tex](x+1)^{2}=x^{2}+2x+ 1\\\\(x-1)^{2}=x^{2}-2x+ 1[/tex]

We can see that for these first two options, the value of m has not the same value for the coefficient of the linear term and the constant term since m is equal 2 and the constant number is not 2.

- Trying with the third option, we have:

[tex](x+2)^{2}=x^{2}+2*(2*x)+2^{2}=x^{2} +4x+4[/tex]

Now, we can see that the value of m is the same for the coefficient of the linear term and the constant term, we can see that m is equal to 4.

So, the correct option is the third option, because

[tex]m=4[/tex]

[tex]x^{2} +mx+m=(x+2)^{2}=x^{2} +4x+4=x^{2} +mx+m[/tex]

Final answer:

To find the length of the wall on the new blueprint with a scale of 1 cm = 3 ft, a proportion can be used. The length of the wall on the new blueprint would be 0.75 ft.

Explanation:

To find the length of the wall on the new blueprint with a scale of 1 cm = 3 ft, we can use a proportion.

In the original blueprint with a scale of 1 cm = 4 ft, the length of the wall is 9 cm. Let's let x represent the length of the wall on the new blueprint.

Set up the proportion: 1 cm/4 ft = x cm/3 ft

Cross multiply: 1 * 3 = 4 * x

Solve for x: x = 3/4

Therefore, the length of the wall on the new blueprint would be 3/4 ft or 0.75 ft.

From the function sin(x+y) - sin(x-y) = 2f(x)sin(y), we can deduce that f(x) = cosx

But sin(x + y) = sinxcosy + cosxsiny.

Also, sin(x - y) = sinxcosy - cosxsiny..

Hence:

sin(x+y) - sin(x-y)

= sinxcosy + cosxsiny - (sinxcosy - cosxsiny)

=  sinxcosy -  sinxcosy + cosxsiny + cosxsiny

= 2cosxsiny

2cosxsiny = 2f(x)sin(y)

Hence, f(x) = cosx

Step-by-step explanation:

the mom is 55 in 15 years

100-55=45

45-30=15

15x2=30

Answer:

15 and 5

Step-by-step explanation:

Mother's current age:  40

daughter's age:  d

son's age:  s

son is 2x as old as daughter:  s = 2d

Then, 15 years from now, the sum of their ages will be:

(40 + 15) + (2d + 15) + (d + 15) = 100

or

55 + 15 + 15 + 3d = 100

85 + 3d = 100, or 3d = 15, or d = 5.

Then the son's age is 3(5) = 15 and the daughter's is 5.

To find how many small cubes can fit inside a larger cube, you need to find the volume of both.

Once you have the volumes, divide the volume of the larger cube, by the volume of the smaller cube.

Volume = L x W x H

Small cube: Volume = 3/4 x 3/4 x 3/4 = 0.421875 cm^3

Large cube: Volume = 3 x 3 x 2 = 18 cm^3

Number of small cubes that can fit: 18 / 0.421875 = 42.67 Cubes.

Since you can't have a partial cube ( 0.67) round down to a whole number:

That means you can fit 42 cubes.

Step-by-step explanation:

[tex]45-\frac{90}{x} = 15[/tex]

Minus 45 from both sides

[tex]-\frac{90}{x}=-30[/tex]

Multiply both sides x

[tex]-90=-30x[/tex]

Divide both sides by -30

Step-by-step explanation:

To eliminate the x on the denominator, multiply all terms by x

45x - 90 = 15x ( subtract 45x from both sides )

- 90 = - 30x ( divide both sides by - 30 )

Step-by-step explanation:

The complete question is as follows:-

The levels of mercury in two different bodies of water are rising. In one body of water, the initial measure of mercury is 0.05 parts per billion (ppb) and is rising at a rate of 0.1 ppb each year. In the second body of water, the initial measure is 0.12 ppb and the rate of increase is 0.06 ppb each year. Which equation can be used to find y, the year in which both bodies of water have the same amount of mercury?

An equation can be used to find y, the year in which both bodies of water have the same amount of mercury will be given as below:-

0.05 + 0.1y  =  0.12 + 0.06y

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Here, we want to find y which is the heat in which the amount of mercury in each of the water bodies is the same.

Now for the first water body:

Initial is 0.05 ppb and after y years, we have a rise of 0.1  x  y = 0.1y ppb

So the amount of mercury in ppb after y years would be;

0.05 + 0.1y

For the second water body;

Initial is 0.12 and a rise of 0.06 ppb per year for y years. The rise would be

0.06  x  y = 0.06y

So the total amount of mercury here is

0.12 + 0.06y

So to find y which is the year the amount of mercury in each water body is the same, we simple equate both and that would be;

0.05 + 0.1y = 0.12 + 0.06y

Therefore an equation can be used to find y, the year in which both bodies of water have the same amount of mercury is 0.05 + 0.1y  =  0.12 + 0.06y

Using cross products

7x = 4*28

Divide each side by 7

x = 4 * 4

x = 16

It’s is 35968.1 since you need to find the radius since area=pie time the radius squared, so divide 214 by 2 to get 107 then multiply pie time 107 to the second power to get 35968.1

The value of [tex]\(x\)[/tex] is [tex]\(14\)[/tex]. The correct option is [tex]\(14\)[/tex].

In a right triangle with a 45-degree angle, the sides are related by the special angles of 45-45-90 triangles. In such triangles, the sides are in the ratio [tex]\(1:1:\sqrt{2}\)[/tex].

Given that the height is [tex]\(7\sqrt{2}\)[/tex] and the hypotenuse is [tex]\(x\),[/tex] we can identify the relationship as follows:

[tex]\[ \text{Height} : \text{Base} : \text{Hypotenuse} = 1 : 1 : \sqrt{2} \][/tex]

So, the height is [tex]\(7\sqrt{2}\)[/tex], and the base would be [tex]\(7\sqrt{2}\)[/tex]as well, and the hypotenuse [tex](\(x\))[/tex] would be [tex]\(7\sqrt{2} \times \sqrt{2} = 7 \times 2 = 14\)[/tex].

Therefore, the value of [tex]\(x\)[/tex] is [tex]\(14\)[/tex], and the correct option is:

• [tex]\(14\)[/tex]

The correct answer is [tex]\boxed{14}[/tex]. The value of x is  [tex]\boxed{14}[/tex].

To determine the value of [tex]\( x \)[/tex], we need to consider the given options and the context of the question, which involves the square root of 2. The options provided are [tex]\( 7 \), \( 7\sqrt{2} \), \( 14 \), and \( 14\sqrt{2} \).[/tex]

Let's analyze the options:

1. [tex]\( 7 \)[/tex] is a straightforward integer.

2. [tex]\( 7\sqrt{2} \) is \( 7 \)[/tex] times the square root of 2, which is an irrational number approximately equal to [tex]\( 1.414 \)[/tex].

3.[tex]\( 14 \) is \( 7 \)[/tex] times [tex]\( 2 \)[/tex], which is a simple integer multiplication.

4. [tex]\( 14\sqrt{2} \) is \( 14 \)[/tex] times the square root of 2.

Given that the question is asking for the value of [tex]\( x \)[/tex] and the options involve multiples of [tex]\( 7 \)[/tex] and [tex]\( 14 \)[/tex], it is reasonable to suspect that the answer might involve the square root of 2, since it is the only mathematical operation present in all the options.

However, without additional context or a mathematical equation to solve for [tex]\( x \)[/tex], we cannot definitively determine which of these options is correct based solely on the information given. In mathematics, problems involving square roots typically require an equation or a geometric representation to provide a clear path to the solution.

Since the question does not provide an equation or additional context, we must rely on the principle that the most straightforward answer is often correct when dealing with multiple-choice questions. In this case, the simplest option that does not involve an irrational number is [tex]\( 14 \)[/tex].

Therefore, without further information, the most logical and simple choice is [tex]\( 14 \)[/tex], as it is a whole number and does not introduce the complexity of an irrational number like [tex]\( \sqrt{2} \)[/tex].

Thus, the final answer is [tex]\boxed{14}[/tex].

Step-by-step explanation:

x²-4x+9=0 can be solved in a variety of ways; the first two that come to mind that are also appropriate are (1) completing the square and (2) using the quadratic formula.

Completing the square is fast here:

Rewrite x²-4x+9=0 as   x²-4x                    +9=0

Identify the coefficient of the x term:  it is -4

Take half of that, obtaining -2

Square this result, obtaining 4

Add 4 to   x²-4x                    +9=0, in the blank space in the middle, and then subtract 4:      x²-4x +4          -4         +9=0

Rewrite           x²-4x +4 as the square of a binomial:

                          (x - 2)² - 4 + 9  = 0  →    (x - 2)²  = -5

Take the square root of both sides:       x - 2  = ±√(-5)  =  ± (i)√5

Then x = 2 ± (i)√5

[tex]x = 75.5 \degree[/tex]

EXPLANATION

Lines WO and WX are tangents to the circle.

The angle subtended at the center, Z by minor arc XO is the angle subtended at the circumcenter by the same arc.

Therefore the central angle is 2x°.

The two radii ZX and ZO meets the tangents at right angles.

This implies that:

[tex]2x + 90 + 90 + 29 = 360 \degree[/tex]

Or

[tex]2x + 29 = 180 \degree[/tex]

[tex]2x = 180 - 29[/tex]

[tex]2x = 151[/tex]

Divide both sides by 2

[tex]x = \frac{151}{2} = 75.5[/tex]

The value of x using the quadratic equation is 0.00139. When adjusting exponential notations, move the decimal left or right, depending on whether the exponent is positive or negative. Verifying precision to a certain number of decimal places can be achieved by altering the increment and observing changes beyond the desired precision.

To find the value of x when using the quadratic equation, we have two potential solutions, which are x= -0.0024 and x= 0.00139. In practical applications, a negative result may not be viable, which indicates that x would equal to 0.00139. When dealing with exponential notation, moving the decimal to adjust for the exponent is necessary. For instance, 4.5 x 10¹ would become 0.45 when the decimal is moved one place to the left. Similarly, 1.6 x 10² would adjust to 160 by moving the decimal place to the right two places. Conversely, a negative exponent like in 2.4 x 10⁻² requires moving the decimal to the left twice to get 0.024. Understanding this concept is crucial when working with numbers written in scientific notation.

If we're verifying to three decimal places and see a change beyond the third decimal (such as with Ax=10⁻⁵ resulting in 1.00001), we can deduce that the initial three decimal places are indeed accurate. Hence, an answer like 1.00001 confirms that 1.000 is valid up to three decimal places. Additionally, using Newton's method can improve approximations, such as refining an initial estimate of the solution to tan x = x from about 4.5 to a more precise six decimal places.
