If one-third of a number, x, is greater than five less than twice the number, which of the following is true?​ x < 3, x > -3, x > -3/5, x < 3/5

Option A

The true inequality is x < 3

Let the number be "x"

One third of number means that,

[tex]\rightarrow \frac{1}{3} \text{ of number } = \frac{1}{3} \times x = \frac{x}{3}[/tex]

Thus from given statement,

one-third of a number x is greater than five less than twice the number

[tex]\text{ one-third of a number x } > \text{ five less than twice the number x }[/tex]

[tex]\frac{x}{3} > 2x - 5[/tex]

Solve the above inequality

Multiply both sides of inequality by 3

[tex]\frac{x}{3} \times 3 > (2x - 5) \times 3[/tex]

[tex]x > 3(2x-5)[/tex]

Solve for brackets in R.H.S

[tex]x > 6x - 15[/tex]

Add -6x on both sides of inequality

[tex]x - 6x > 6x - 15 -6x\\\\-5x>-15[/tex]

Multiply both sides of inequality by -1

Whenever you multiply or divide an inequality by a negative number, you must flip the inequality sign

[tex]5x < 15[/tex]

Divide both sides of inequality by 5

[tex]x < 3[/tex]

Thus the true inequality is x < 3

Final answer:

The inequality one-third of a number x being greater than five less than twice the number translates to x < 3 after solving the inequality properly.

Explanation:

If one-third of a number, x, is greater than five less than twice the number, we can write this as an inequality. To solve for x, we can set up the following expression:

Now, we need to solve for x. First, we'll get all the x terms on one side and the constants on the other:

The statement that is true is that x is less than 3. This means all solutions for x are numbers that are less than 3.

To find the total cost for Don's class trip, including the bus rental and theater tickets, the cost and number of tickets are required. Currently, with only the bus rental cost known at $168, we can't calculate the final total cost.

To solve the problem of determining the total cost of the bus rental and theater tickets for Don's class, we first identify the information given and what is required. We know the cost of the bus rental, which is $168. However, the question does not specify the cost of theater tickets. Therefore, to get the total cost, we would need the number of theater tickets needed and the price per ticket. Once these details are provided, the total cost can be calculated using the formula:

Total Cost = Cost of Bus Rental + (Number of Theater Tickets × Cost per Theater Ticket)

Without the cost and quantity of theater tickets, we can only provide the initial part of the answer, which is the cost of the bus rental.

And admission and [tex]9[/tex] samples costs $[tex]11.75[/tex]

Let cost of the sample is [tex]y[/tex] and number of sample is [tex]x[/tex]

Now, we will find the slope of line

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{11.75-8.75}{9-6}\\\\m=\frac{3}{3}\\\\m=1[/tex]

Plug slope as [tex]1[/tex] and point [tex](6,8.75)[/tex] in the equation we get,

[tex](y-y_1)=m(x-x_1)\\y-8.75=1(x-6)\\y-8.75=x-6\\y=x-6+8.75\\y=x+2.75[/tex]

The equation of line will be [tex]y=x+2.75[/tex]

Answer:

A) The teacher brought 384 fluid ounces of juice

B)NO, the teacher doesn't have enough juice to give each student a 12-fluid ounce glass of juice

Step-by-step explanation:

Given:

The total quantity of juice brought by the teacher for the field trip = 3 gallons of juice

The number of students in the field trip =  36

A)fluid ounces of juice

We know that

1 gallon  = 128 fluid ounce

So we have to convert the given 3 gallons of juice to fluid ounces

3 gallons of fruit juice [tex]= 3 \times 128[/tex] fluid ounces

3 gallons of fruit juice  =  384 fluid ounces

The teacher had 384 fluid ounces of fruit juice

B. enough juice to give each student a 12-fluid ounce glass of juice

The teacher wants to give 12 fluid ounce of juice to one student

So, to give 36 students

the teacher will need

=> [tex]36 \times 12[/tex]

=> 432 fluid ounces of juice

but the teacher has only 384 fluid ounces of juice .

Thus the teacher still  needs 48 fluid ounces of juice

Hence the correct option is the fourth option.

Answer:

Step-by-step explanation:

∠ABC = ∠BCD    { AB // CD; BC TRAVERSAL, alternate angles are equal}

∠ABC = 20

∠BCA = ∠BAC     {angles opposite to equal sides are equal}

∠BCA = ∠BAC = x

x + x + 20 = 180

2x = 180 - 20

2x = 160

x = 160/2

x = 80

The lines AB and CD are said to be parallel and thus, corresponding angles ∠CB and ∠BD, are equal in value. Hence the value of x is calculated by subtracting the value of known angle ∠BCD (20°) from the total sum of interior angles of a straight line (180°), obtaining a result of 160°.

In this given geometry problem, the lines AB and CD are parallel to each other and BC∠BCD = 20°. Since AB is parallel to CD, then the angles ∠CB and ∠BD, being corresponding angles, are equal. Hence, ∠CB also equals 20°.

Now, since ∠BCD and ∠CB make a straight line, the sum of their interior angles is equal to 180°. So, if we subtract the known 20° from 180°, we can find the value of unknown angle ∠BCD. Hence, x = 180° - 20° = 160°.

Answer:

Infinitely many solution.

Step-by-step explanation:

The given system is

x = y + 4

y = x - 4

To graph the first equation, we write it in slope-intercept form to get: to

x=y+4

This implies y=x-4.

This has a slope of 1 and a y-intercept of -4.

The graph of this function is shown in the attachment.

The second equation is y=x-4.

This equation is identical to first equation, so its graph coincides with the first one.

The system has infinitely many solution.

The system of equations has infinitely many solutions.

The system of equations:

1. [tex]\( x = y + 4 \)[/tex]

2. [tex]\( y = x - 4 \)[/tex]

can be rearranged to show that they represent the same line:

1. [tex]\( y = x - 4 \)[/tex] (Rearranged from [tex]\( x = y + 4 \)[/tex])

2. [tex]\( y = x - 4 \)[/tex]

Graphing these equations shows that they are the same line, meaning every point on the line [tex]\( y = x - 4 \)[/tex] is a solution to the system.

Thus, the solution to the system of equations is all points [tex]\((x, y)\)[/tex] that satisfy [tex]\( y = x - 4 \)[/tex]. This means the lines intersect everywhere along [tex]\( y = x - 4 \)[/tex].

There is no single intersection point because they overlap completely.

Answer:

The manual cost that will take to recreate by the firm is $ 90.51

Step-by-step explanation:

Given:

Number of words the manual contains= 16000

Number of words typed by a clerk in one hour and 20 minutes = 4160

To Find:

The total cost for recreating the manual = ?

Solution:

Step 1:  Finding the Number of hours is need to type 4160 words :

= [tex]1\frac{20}{60}[/tex] hours

[tex]\\\\=1\frac{1}{3}[/tex] hours

[tex]\\\\=\frac{4}{3}[/tex] hours

So it takes  [tex]\frac{4}{3}[/tex] hours to type 4160 word

Step 2 :  Finding the Number of hours is needed to type 1 word  

= [tex]\frac{4160}{\frac{4}{3}}[/tex]

=[tex]4160 \times \frac{3}{4}[/tex]

= 3120 words per hour

Step 3 :  Finding the Number of hours is needed to type 16000 words

=[tex]\frac{\text{ total number of words}} {\text{ number of words written per hour}}[/tex]

Substituting the values

= [tex]\frac{16000}{3120}[/tex]

=  5.1282 hours

Step 4 :  Finding the cost for recreating the manual.

= number of hours  x cost per hour

=   5.1282 x $17.65

=  90.51

Recreating the manual will cost the firm approximately $90.59.

To determine the cost of recreating the manual, we need to calculate both the time it will take for the clerk to type the entire manual and the total cost based on the clerk's wage.

First, we calculate the time required to type the manual. The clerk types 4,160 words in 1 hour and 20 minutes. To find out how many minutes that is, we convert 1 hour to minutes:

1 hour = 60 minutes

Therefore, 1 hour and 20 minutes is:

60 minutes + 20 minutes = 80 minutes

Now, we need to find out how many 80-minute blocks are required to type 16,000 words. We set up a proportion:

4,160 words / 80 minutes = 16,000 words / x minutes

Solving for x gives us:

x = (16,000 words x 80 minutes) / 4,160 words

x = (16 x 80) / 4.16

x = 1,280 / 4.16

x ≈ 308 minutes

Next, we convert the total time from minutes to hours since the clerk is paid by the hour:

308 minutes / 60 minutes per hour ≈ 5.13 hours

Now, we calculate the total cost by multiplying the total hours by the clerk's hourly wage, including benefits:

Total cost = 5.13 hours x $17.65/hour

Total cost ≈ $90.59

Therefore, recreating the manual will cost the firm approximately $90.59.

Find the average rate of change of f(x) = 3(2)^x between x = 1 and x = 4

The average rate of change is 14

The rate of change is given by formula:

[tex]\text { Average Rate }=\frac{f(b)-f(a)}{b-a}[/tex]

Here the given interval is x = 1 and x = 4

Therefore, the formula becomes,

[tex]\text { Average Rate }=\frac{f(4)-f(1)}{4-1}\\\\\text { Average Rate }=\frac{f(4)-f(1)}{3}[/tex]

Let us find f(4) and f(1)

Given function is:

[tex]f(x)=3(2)^x[/tex]

Substitute x = 4 in function

[tex]f(4)=3(2)^4\\\\f(4) = 3 \times 16 = 48[/tex]

Thus f(4) = 48

Substitute x = 1 in function

[tex]f(1) = 3(2)^1\\\\f(1) = 6[/tex]

Now substitute the values back into formula

[tex]\text { Average Rate }=\frac{f(4)-f(1)}{3}\\\\\text { Average Rate }= \frac{48-6}{3}\\\\\text { Average Rate }= 14[/tex]

Thus average rate of change is 14

The volume of the paper cone to the nearest tenth = 268.0 in².

Volume of cone, V = (1/3) πr²h

Where, h= height of the cone

r = radius of the cone

V= volume of the cone

In our case, we are given r = 4" and h = 16"

substituting this into the equation:

V = (1/3) πr²h

Substitute into the formula we have

The value of π = 3.14

V =  (1/3) ·(3.14) · (4)²· (16)

= 267.94667 in²

= 268.0 in² (nearest tenth)

Answer:

Ten amounts:

$ 13,979 $1,000 $100 $2 $10 $300 $4 $5 $200 $500

Step-by-step explanation:

Choose any numbers you want for the first 9 cash amounts. Then, find out the difference between the 9 cash amounts and 16,100. That will be the tenth amount.

Example:

I choose $1,000 $100 $2 $10 $300 $4 $5 $200 $500.

If I add them together, I get $2,121.

Remember that was 9 amounts, and we need 10.

To get the last amount, subtract what you have ($2,121) from what you need ($16,100).

16,100 - 2,121 = $13,979

The last amount will be $13,979.

Check your answer:

Add all of the ten amounts to get 16,100.

1,000 + 100 + 2 + 10 + 300 + 4 + 5 + 200 + 500 + 13,979

= 16,100

Therefore this answer is correct.

y - y1 = m(x - x1)

slope(m) = -1

(-1,5)....x1 = -1 and y1 = 5

now we sub

y - 5 = -1(x - (-1)...not done yet...we can simplify this

y - 5 = -1(x + 1) <===

The solution is y = -x + 4

The equation of the line is y = -x + 4 and the slope of the line is m = -1

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the point be represented as P = P ( -1 , 5 )

Now , the slope of the line is

Slope m = -1

The equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 5 = -1 ( x - ( -1 ) )

On simplifying the equation , we get

y - 5 = -1 ( x + 1 )

y - 5 = -x - 1

Adding 5 on both sides of the equation , we get

y = -x + 4

Therefore , the value of A is y = -x + 4

Hence , the equation of line is y = -x + 4
