Hello! I need a little bit of help with this question please! (This is not from an active test, it is from a book I am using to study for my ASVAB.)

Answer: ? = 1/2

Step-by-step explanation:

Your question is a bad example, so let me come up with one.

2/8 = 1/4

This is done by dividing both the numerator and denominator by the same value: 2/8 / 2/2

or

2/2 = 1, 8/2 = 4

We now have 1/4

or 9/36

What can we divide 36 by, 9 by? We need to divide by both for it to work.

9/3 = 3

36/3 = 12

3/12 But we can divide this again

3/3 = 1

12/3 = 4

1/4, we could also have divided 9/36 by 6/6 to get 1/4

For 1/8 to get ?/4, we do

8/? = 4

? = 1/2

, so the answer is 1/2/4 = 1/2*4 = 1/8

We know that:

Above, we use the transitive property

Answer:

You cannot multiply or divide for 4 and 3 so no false

Answer:

l=10.5 in , w=16.5 in

Step-by-step explanation:

p=2l+2w
54=2(w-6)+2(w)
54=2w-12+2w
54=4w-12
66=4w
w= 16.5
l=w-6
l=16.5-6

l=10.5 in
w=16.5 in

Step-by-step explanation:

If you add all the numbers and then divide by the number of numbers given you get the average.

If a monument in the form of a marble cylinder has a circular base with a radius 1.5 meters and the altitude of the monument is 3.5 meters. then the quantity of marbles contains in the monument is 24.74 meter cube

The shape of the monument  is cylinder

The base radius of the cylinder = 1.5 meter

The altitude of the monument = 3.5 meters

The volume of the cylinder = [tex]\pi r^{2}h[/tex]

Where r is the radius of the cylinder

h is the height of the cylinder

Substitute the values in the equation

The volume of the cylinder = [tex]\pi (1.5)^{2}(3.5)[/tex]

= 24.74 meter cube

Hence, If a monument in the form of a marble cylinder has a circular base with a radius 1.5 meters and the altitude of the monument is 3.5 meters. then the quantity of marbles contains in the monument is 24.74 meter cube

The expected number of the real workers in any sample of size 50 is 35

Algebra is a branch of mathematics that facilitates the description of problems or situations into mathematical statements. It involves variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division to generate a valid mathematical statement. All branches of mathematics, such as coordinate geometry, calculus, and trigonometry, employ algebra. An elementary algebraic formula is 2x + 4 = 8. Algebraic expressions serve as the mathematical statement when operations on variables and constants, such as addition, subtraction, multiplication, division, etc., are done. Assume James and Natalie had the notion to arrange the matchsticks into numerical patterns while they were fiddling with them.

Given that : A random sample of n = 50 teachers was selected from a Local Government and it has been established that 30% of the entire teachers are ghost workers and 70% are real workers.

n= 50

30 % are ghost workers

= 30% 0f 50

Answer:

160,000

Step-by-step explanation:

The composite function F(1) has a value of 2

The definition of the composite function is given as

F(x) = f(xf(xf(x)))

Also, we have

f(1) = 2, f(2) = 5, f '(1) = 4, f '(2) = 5, and f '(5) = 6,

Substitute 1 for x in the equation F(x) = f(xf(xf(x)))

So, we have

F(1) = f(xf(xf(1)))

From the question

f(1) = 2

So, we have

F(1) = f(xf(2))

From the question

f(2) = 5

So, we have

F(1) = f(5)

As a general rule

If f '(2) = 5 then f(5) = 2

So, we have

F(1) = 2

Hence, the value of the function F(1) is 2

Answer:

First option is correct.

Step-by-step explanation:

Normally, Pete's dad deposits $25 into his bank account every week.

Now, he wants to deposit x extra dollars for 8 weeks. So, the total deposits for these 8 weeks will be:

8*(25 + x)

He wants to keep the total deposits above 500. So

8*(25 + x) > 500

Now we solve the inequality similarly to how we would solve an equality.

8*(25 + x) > 500

200 + 8x > 500

8x > 500 - 200

8x > 300

x > 300/8

x > $37.50

So the first option is correct.

Step-by-step explanation:

The equation that represents the daily production cost based on the number of pairs of boots manufactured each day is C(x) = 4.75x + 400.

What are linear equations?
Linear equations are a subset of first order equations. Linear equations are defined for lines in the coordinate system. One homogeneous variable of degree one constitutes a linear equation in one variable (i.e., only one variable). A linear equation could contain multiple variables. When a linear equation comprises two variables, for instance, linear equations in two variables are utilized. A mathematical statement known as an equation contains an algebraic expression and the equal symbol (=). It is the equation for a straight line. The equation is shown to be valid when values are substituted for the unknown values in the solutions of linear equations. When there is just one variable, there is just one answer.

Given, the daily production cost (in $) = C(x)
The number of pairs of boots manufactured = x
The cost of making a pair of boots = $ 4.75
The fixed cost of production each day = $ 400
Thus, net cost of making 'x' boots added to the daily fixed production cost will give the  daily production cost.
Therefore, C(x) = 4.75x + 400, is the correct equation.

The surface area and volume of the polyhedron are mathematically given as

This is further explained below.

Generally, The surface area of a three-dimensional object is equal to the total of areas of all of its faces, also known as surfaces. A cuboid has six faces that are rectangular in shape.

Add together the areas of each of the cube's six sides to get the surface area of the cube. To get the surface area of the prism, we may additionally label its length (l), width (w), and height (h), and then use the formula surface area = length (l) times width (w) times height (h).

To refresh your memory, the surface area of an item is the entire area of the exterior surfaces of the three-dimensional object or the total sum of the area of the faces of the object.

In other words, the surface area of an object is its "face area." It is expressed in terms of square units as a measurement.

Measure of the angle m ∠ RQS = 58 ° for the given circle with arc RS subtending m ∠RPS=14 x + 46 ° at the center P and m ∠ RQS = 3 x + 43 ° at Q, on the circumference.

As given in the question,

Measure of the angle is given by :

m ∠ RPS=14 x + 46 °                                  

m ∠ RQS=3 x + 43 °                                      

m ∠ RPS = twice m ∠RQS (angle subtended at center of the circle)

14 x +46 =2(3 x + 43)

⇒ 14x + 46 = 6x +86

⇒ 14x-6x=86-46

⇒8x=40

⇒ x=5°

m ∠ RQS = (3 x + 43) °  

                 =[3(5) + 43 ]°

                 = 58°

Therefore, measure of the angle in the given circle m ∠RQS is equal to the  58 °

Is there two columns of data and two data points? Like this:

peaches          Water

40                    30

400                  300

If so, then there are two ways to do it.

1) You can set up a ratio like this

40/30 = x

:-Where x is the number  of peaches for every cups of water .

So;

x = 40/30  peaches

x = 4/3  peaches

2) Look at the increase from one to the other.

3 cups of water requires 4 peaches.

5/9 is yellow

Using integrals, the 90th percentile of the given probability distribution is of $53.58.

The amount exceeded only 10% of the time is the 90th percentile of the distribution, which is the value of p for which:

[tex]\int_0^p f(y) dy = 0.9[/tex]

The integral represents the cumulative density function of the distribution, which is the reason why we use it to find the 90th percentile of the distribution.

The function is given by:

f(y) = 3(1 - y)²

Hence the integral is calculated as follows:

[tex]\int_0^p 3(1 - y)^2 dy[/tex]

Applying the integral of the power of y rule, along with the substitution, it is found that:

[tex]\int 3(1 - y)^2 dy = -(1 - y)^3[/tex]

Hence:

[tex]\int_0^p 3(1 - y)^2 dy = -(1 - y)^3|_{y = 0}^{y = p}[/tex]

Applying the Fundamental Theorem of Calculus, considering the value of the definite integral, it is found that:

-(1 - p)³ + 1 = 0.9

-(1 - p)³ = -0.1

(1 - p)³ = 0.1

Applying the cube root to both sides:

1 - p = 0.4642.

p = 1 - 0.4642

p = 0.5358.

This amount is in hundredths of dollars, hence the 90th percentile of the given probability distribution is of $53.58, as 0.5358 x 100 = $53.58.
