Write the number with the lest value using the digit 1 through 9. Use each digit 1 through 9.use each digit only once. Please it do tomorrow I need help please
Answer:The number should be 123456789.
Step-by-step explanation:
The total digits should be 9 i.e. 1, 2, 3, 4,5, 6,7, 8, and 9.
The largest number should be at the unit place, the 2nd largest number should be at the tenth place, and the 3rd largest number should be at the 100th place, and so on.
So in this way, the 1 number should be written at the left-most position.
Therefore we can conclude that The number should be 123456789.

let's bear in mind that we have two fractions whose denominators are 2 and 4, thus their LCD will be 4, now let's multiply both side by that LCD to do away with the fractions, but let's add some first.
[tex]\bf 2-\left( 4-\cfrac{1}{2}x \right)=6\left( \cfrac{1}{4}x-1 \right)\implies 2- 4-\cfrac{x}{2} =\cfrac{6x}{4}-6 \\\\\\ -2-\cfrac{x}{2} =\cfrac{6x}{4}-6\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{4}}{4\left( -2-\cfrac{x}{2} \right)=4\left( \cfrac{6x}{4}-6 \right)}\implies -8-2x=6x-24 \\\\\\ 16-2x=6x\implies 16=8x\implies \cfrac{16}{8}=x\implies 2=x[/tex]
If ST = 12 and RT = 49, find RS.
Given ST = 12 and RT = 49, we apply the basic principle of part-whole relationships in a line to find RS. By subtracting the length of ST from RT, we determine that RS equals 37.
Explanation:The question asks to find the length of RS given that ST = 12 and RT = 49. To find the length of RS, we can apply the concept that in a linear situation, if S is a point between R and T, then RS + ST = RT. This concept is based on the principle of the sum of parts of a whole.
Given:
ST = 12RT = 49To find RS, we use the equation:
RS + ST = RT
Plugging in the given values:
RS + 12 = 49
Solving for RS, we subtract 12 from both sides:
RS = 49 - 12
RS = 37
Therefore, the length of RS is 37.

Colin Katz works at his father's restaurant eight hours a day, earning $10.75 an hour. He is asked to work
two additional hours at time and a half to help prepare for a banquet. How much will he earn for these two
hours of overtime?
The offered overtime hourly rate is 1.5 times the given hourly rate.
Correct Response;The amount he will earn for the two hours overtime is $32.25Methods by which the above value is calculated;The amount Colin Katz earns per hour = $10.75
The number of additional hours Colin Katz is asked to work = 2 hours
Rate at which the additional hours will be paid = Hourly rate and half = 1.5 hourly rate
Required:The amount he will earn for the additional hours.
Solution:The hourly rate for the additional hours = 1.5 × $10.75 = $16.125
Amount Colin Katz earns working 2 additional hours = 2 × $16.125 = $32.25
The amount he will earn for the two hours overtime = $32.25

Use function notation to represent how much the volume of the box (in cubic inches) changes by if the cutout length increases from 0.3 inches to 1.2 inches.
To calculate the change in volume of a box when cutout length increases from 0.3 inches to 1.2 inches using function notation, use the formula ΔV=f(l2)-f(l1), where f(l) represents the volume of the box given the length of the edge.
Explanation:The change in volume when the cutout length increases from 0.3 inches to 1.2 inches can be represented in function notation as ΔV=f(l2)-f(l1), where f(l) represents the volume of the box as a function of the length (l) of the edge. Here, l1=0.3 and l2=1.2.
Given the formula for the volume of the box V = Length x Width x Height. Let's assume Width and Height remain constant. If initially the volume was V1=f(l1) and finally it became V2=f(l2), the change in volume will be ΔV=V2-V1 which equals f(l2)-f(l1).
For example, if the width and height of the box are 6 inches and 3 inches respectively, then the initial volume is V1 = 0.3 x 6 x 3 cubic inches and the final volume is V2 = 1.2 x 6 x 3 cubic inches. Therefore, ΔV = (1.2 x 6 x 3) - (0.3 x 6 x 3) cubic inches.

The change in the volume of the box when the cutout length increases from 0.3 inches to 1.2 inches can be calculated using the function ΔV = V(1.2) - V(0.3). Assuming the rest of the box's dimensions are constant, this results in a change in volume of 16.2 cubic inches.
To use function notation to represent how the volume of the box changes by if the cutout length increases from 0.3 inches to 1.2 inches, let us first define a function V(l) that represents the volume of the box as a function of the cutout length 'l'. If the initial cutout length is 0.3 inches and the final cutout is 1.2 inches, the change in length Δl would be 1.2 inches - 0.3 inches = 0.9 inches. We can express the change in volume, ΔV, as the function of the change in cutout length as follows: ΔV = V(1.2) - V(0.3).
Given that the volume of a rectangular box can be calculated by the formula volume = length × width × height, and assuming other dimensions of the box do not change, the function V(l) becomes:
V(l) = length × width × l
Let's consider an example where the dimensions of the box remain constant at 6 inches by 3 inches. The volume function would then be:
V(l) = 6 in. × 3 in. × l in.
The change in volume for an increase in cutout from 0.3 to 1.2 inches is then:
ΔV = V(1.2) - V(0.3) = (6 × 3 × 1.2) - (6 × 3 × 0.3) = 21.6 in.³ - 5.4 in.³ = 16.2 in.³.

Answer:
[tex] u = -\dfrac{vx}{w} [/tex]
Step-by-step explanation:
You are allowed to multiply and divide both sides of an equation by the same non-zero number or non-zero variable. Do the appropriate operations to isolate the u.
[tex] x = -\dfrac{1}{v}uw [/tex]
We are solving for u, so first, switch sides.
[tex] -\dfrac{1}{v}uw = x [/tex]
Multiply both sides by v.
[tex] -\dfrac{1}{v}uw \times v = x \times v [/tex]
[tex] -uw = x \times v [/tex]
Divide both sides by -w.
[tex] \dfrac{-uw}{-w} = \dfrac{xv}{-w} [/tex]
[tex] u = -\dfrac{vx}{w} [/tex]

The factorized form of the equation 4x² + 12x - 72 is
A = 4 ( x + 6 ) ( x - 3 )
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Now , the equation can be simplified by
A = 4 ( x² + 3x - 18 )
Now , on simplifying the equation , we get
A = 4 ( x² - 3x + 6x - 18 )
Now , on grouping the similar terms in the equation , we get
A = 4 ( x ( x - 3 ) + 6 ( x - 3 ) )
A = 4 ( x + 6 ) ( x - 3 )
So , the factorized form of the equation is
A = 4 ( x + 6 ) ( x - 3 )
Hence , The factorized form of the equation 4x² + 12x - 72 is
A = 4 ( x + 6 ) ( x - 3 )

,It will Connect the two intercepts with a straight line
2x + 3y = 1,470
3y = -2x + 1470
y = (-2x + 1470 ) / 3
y = -2/3 * x + 1470/3

Step-by-step explanation:
Answer:
[tex]2x+3y=1470[/tex]
Step-by-step explanation:
Givens
The profit on every sandwich is $2.The profit on every wrap is $3.Sal made $1470 in profits.So, [tex]x[/tex] represents the number of sandwiches and [tex]y[/tex] represents the number of wraps, so the profit on each food is
[tex]2x[/tex] and [tex]3y[/tex], so the sum of them must be equal to $1470, as follows
[tex]2x+3y=1470[/tex]
Which is a linear equation, that means if we graph, it would be a line.
To graph this, we just need to find two points.
For [tex]x=0[/tex], let's find [tex]y[/tex]
[tex]2x+3y=1470\\2(0)+3y=1470\\y=\frac{1470}{3}=490[/tex]
For [tex]y=0[/tex]. let's find [tex]x[/tex]
[tex]2x+3y=1470\\2x+3(0)=1470\\x=\frac{1470}{2}=735[/tex]
Therefore, the two points to graph the line are [tex](0,490)[/tex] and [tex](735, 0)[/tex]. Now, we graph these coordinates and draw a line that must cross them
The resulting graph should be like the image attached.
