Answer:

m = 3.86

Step-by-step explanation:

D = 6 / 7

D = m + 3

6 / 7 = m + 3

6 / 7 + 3 = m

m = 3.86

The instructions state "there are a  minimum of 16 players and at most 20  players on the team". This means that we have between 16 and 20 players, inclusive of both endpoints. Therefore, x can take on any whole number between 16 and 20. The domain is the set of allowed x inputs of a function.

Answer:

s = 1.17, -23.17

Step-by-step explanation:

s^2 + 22s = 27

Take the coefficient of s

22

Divide by 2

22/2 =11

Square it

11^2 =121

Add this to both sides

s^2 + 22s+121 = 27+121

s^2 + 22s+121  = 148

(s+11)^2 = 148

Take the square root of each side

sqrt((s+11)^2) = ±sqrt(148)

s+11 =  ±sqrt(148)

Subtract 11 from each side

s+11-11 = -11  ±sqrt(148)

s =  -11  ±sqrt(148)

s = -11 + sqrt(148) = 1.1655

   - 11 - sqrt(148)=-23.166

Rounding to the nearest hundredth

s = 1.17, -23.17

Step-by-step explanation:

360÷20 = 18sides

U divide 360 by 20 because angles at the center add up to 360°

The given polygon will have 18 sides in total.

Given information:

The diagram shows part of a regular polygon.

The sides of this polygon subtend angles of 20° at the center of the polygon.

Let the polygon has n number of sides.

Now, the polygon is regular. So, its each side will be equal and it will make equal angle with the center.

The sum of angles made by all the sides will be equal to 360 degrees.

So, the number of sides n can be calculated as,

[tex]20\times n=360\\n=\dfrac{360}{20}\\n=18[/tex]

Therefore, the given polygon will have 18 sides in total.

Answer:

Macy’s

Step-by-step explanation:

let’s find the cost of each shirt

JCPenny’s: 14.99 x 0.80 = $11.99

                   11.99 x 1.06 = $12.70

                   The final cost of the JCPenny shirt is $12.70

Macy’s: 17.99 x 0.65 = $11.69

             11.69 x 1.07 = $12.51

             The final cost of the Macy’s shirt is $12.51

$12.51 is less than $12.70

So, the Macy’s shirt is the better deal :)

Resolviendo un sistema de ecuaciones, veremos que el número de dos cifras es 97.

¿Como encontrar el sistema de ecuaciones?

Podemos escribir un número de dos cifras como:

a*10 + b

Donde a y b son dos numeros de una cifra.

Entonces podemos escribir las restricciones:

"Si un número de dos cifras se disminuye en 17 y esta diferencia se divide por la suma de sus cifras, el cociente es 5"

((a*10 + b) - 17)/(a + b) = 5

"si el número disminuido en 2 se divide por la cifra de las unidades disminuida en 2, el cociente es 19"

(a*10 + b - 2)/(b - 2) = 19

Entonces tenemos un sistema de ecuaciones, que vamos a escribir como:

a*10 + b - 17 = (a + b)*5

a*10 + b - 2 = 19*(b - 2)

Donde pase los denominadores a la derecha, así es más simple de leer.

Para resolver esto, primero debemos simplificar ambas ecuaciones, vamos a obtener:

a*10 + b - 17 = a*5 + b*5

a*10 + b - 2 = 19*b - 38

Moviendo los terminos con variables a la izquierda y los constantes a la derecha:

a*10 + b - a*5 - b*5 = 17

a*10 + b - 19*b = -38 + 2

Terminamos de simplificar:

a*5 - b*4 = 17

a*10 - b*18 = -36

Ahora debemos aislar una de las variables en una de las ecuaciones, vamos a aislar a en le primera:

a = (17 + b*4)/5

Ahora reemplazamos esto en la otra ecuación y resolvemos para b:

10*(17 + b*4)/5 - b*18 = -36

2*(17 + b*4) - b*18 = -36

34 + b*8 - b*18 = -36

34 - b*10 = -36

-b*10 = -34 - 36 = -70

b = -70/-10 = 7

Para encontrar el valor de a usamos la ecuación:

a = (17 + b*4)/5 = (17 + 7*4)/5 = 9

Entonces podemos concluir que el número es 97.

Step-by-step explanation:

Answer:

y = -319/20| x = 377/20

Step-by-step explanation:

/| 7/2-x-y-(3/5) = 0| -11*x-(13*y) = 0

We try to solve the equation: 7/2-x-y-(3/5) = 0

29/10-x-y = 0 // - 29/10-x

-y = -(29/10-x) // * -1

y = 29/10-x

We insert the solution into one of the initial equations of our system of equations

We get a system of equations:

/| -(13*(29/10-x))-11*x = 0| y = 29/10-x

-1*13*(29/10-x)-11*x = 0

2*x-377/10 = 0

2*x-377/10 = 0 // + 377/10

2*x = 377/10 // : 2

x = 377/10/2

x = 377/20

We insert the solution into one of the initial equations of our system of equations

For y = 29/10-x:  

y = 29/10-377/20

y = -319/20

We get a system of equations:

/| y = -319/20| x = 377/20

4x + 16 = 3x + 21

4x - 3x = 21 - 16

x = 5

Answer:

x=5

Step-by-step explanation:

You can approach this question in many different ways, but i'm gonna look at it algebraically, since it's the quickest and works pretty much all the time.

First, you want to convert the words they've given you and make it into a less confusing equation.

They told us that 4 divided by (x+7) = 3 divided by (x+4), which is the same as:

[tex]\frac{4}{x+7}[/tex] = [tex]\frac{3}{x+4}[/tex]

Now, we can multiply both sides by (x+7), which gives me:

4 = [tex]\frac{3(x+7)}{x+4}[/tex]

Now we can multiply both sides by (x+4), to get rid of the fractions:

4(x+4) = 3(x+7)

Then expand the brackets:

4x + 16 = 3x + 21

Move the x to one side and numbers to another side:

4x - 3x = 21 - 16

x = 5

Answer:

10 units

Step-by-step explanation:

Let us find the volume of Haley's prism and compare it with the volume of Jeremiah's.

The volume of Haley's prism is:

V = 5 * 3 * 4 = 60 cubic units

Jeremiah's prism has twice the volume of Haley's:

V(J) = 2 * 60 = 120 cubic units

This implies that:

120 = 4 * 3 * h

where h = height of prism

=> 120 = 12h

=> h = 120 / 12 = 10 units

Jeremiah's prism is 10 units tall.

Answer:

(a+b)(a+b-c)

Step-by-step explanation:

Formula:

(a+b)² = a² + b² + 2ab

Therefore,

a²+b²+2ab -ac-bc

= (a+b)² -ac-bc

Now take -c common in ac and bc

(a+b)² -c(a+b)

now take (a+b) common in both terms

(a+b)(a+b-c)

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.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Answer: the  answer is -0.04 ,1 ,-0.04 ,loss of 0.04 gallons of fuel for every 1 mile

Step-by-step explanation:

From the given table we can noticed that the fuel remaining (gallons) decreases as distance (miles).

It is clear that the distance increases by 1 mile for each next row and the remaining fuel is changed for each next row

The change in fuel remaining from one row to the next in the table is -0.04 gallons.

1) The change in fuel remaining from one row to the next in the table is -0.04 gallons.

2) The change in distance from one row to the next in the table is 1 mile.

3) The slope of the line that runs through the points given in the table is -0.04.

4) The slope is -0.04 it means the remaining fuel decreases by 0.04 gallons in each mile.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now,

From the given table we can noticed that the fuel remaining (gallons) decreases as distance (miles).

Hence, It is clear that the distance increases by 1 mile for each next row and the remaining fuel is changed for each next row is,

⇒ 13.46 - 13.50

⇒ - 0.04

Thus, The change in fuel remaining from one row to the next in the table is -0.04 gallons.

And, The change in distance from one row to the next in the table is 1 mile.

Hence, The slope is the rate of change of remaining fuel with respect to change in distance is,

⇒ m = - 0.04/1

⇒ m = - 0.04

Thus, The slope of the line that runs through the points given in the table is -0.04.

And, The slope indicates a Change in the fuel remaining in each mile. The slope is -0.04 it means the remaining fuel decreases by 0.04 gallons in each mile.
