Answer:

a) (2, 0.5)  (4, 1)

b) V(n) = 0.25n

c) $2.50

d) # quarters = independent

value = dependent

Step-by-step explanation:

The independent value is the number of quarters and the dependent variable is the value of cents and the  equation that represents this function is,

[tex]v(n)=25\times n\rm \;\;cents[/tex]

Algebraic expression are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used to represent the general problem in the mathematical way to solve them.

Steps to write down the simple algebraic expression-

There is total 25 cent is 1 quarter. Thus, when if there are 2 quarters, then the value of cent is 50 and when there are 4 quarters, then the value of cents is 100 cents.

Hence, the two pairs should be as,

(2, 50), (4, 100)

As, v is the value of quarters in cents. There is total 25 cent is 1 quarter. The total quarter is n. Thus, the function can be given as,

[tex]v(n)=25\times n\rm \;\;cents[/tex]

Put the value 10 on the place of n in the above equation as,

[tex]v(10)=25\times (10)\\v(10)=250\rm cents[/tex]

The output when the input is 10 is 250 cents.

The independent value is the number of quarters and the dependent variable is the value of cents.

Hence, the independent value is the number of quarters and the dependent variable is the value of cents and the  equation that represents this function is,

[tex]v(n)=25\times n\rm \;\;cents[/tex]

Heres a photo with explanation

The solution of the equations 2x + 3y = 8 and 3x + 5y = 13 will be (1, 2). Then the value of the expression x + y will be 3.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equations are given below.

2x + 3y = 8             ...1

3x + 5y = 13            ...2

Multiply equation 1 by 3 and equation 2 by -2, then we have

6x + 9y = 24

-6x - 10y = - 26

Add the above equations, then we have

- 26 + 24 = 9y - 10y

y = 2

Then the value of the variable 'x' is calculated as,

3x + 5(2) = 13

3x + 10 = 13

3x = 3

x = 1

Then the value of the expression x + y is calculated as,

⇒ x + y

⇒ 1 + 2

⇒ 3

The solution of the equations 2x + 3y = 8 and 3x + 5y = 13 will be (1, 2). Then the value of the expression x + y will be 3.

Answer:

(X,Y)(18,12)

Step-by-step explanation:

x + y = 30

2x + 4y = 84

___________

2x+2y=60

2x+4y=84

_________

-2y=-24/-2y

y=12

2x+4(12)=84

2x+48=84

2x=84-48

2x/2=36/2

X=18

Answer:

Step-by-step explanation:

3x = y        ------------(I)

y = 2x + 22 ---------------(II)

Substitute y = 2x + 22 in equation (I)

3x = 2x + 22           {Subtract 2x form both sides}

3x -2x = 22              

      x = 22

Plugin x = 22 in equation (I)

3*22 = y

y = 66

Answer:

Step-by-step explanation:

3x = y

y = 2x + 22

3x = 2x + 22      

3x -2x = 22              

x = 22

3x22 = y

66=y

Answer:

131°

Step-by-step explanation:

to find the total degrees of this polygon, we use the equation

=> n - 2 × 180°                         (n= number of sides)

5 - 2 × 180° = 540°

now by using angle sum property,

540° = 80° + 148° + 81° + 100° + [tex]x[/tex]°

540° = 409° + [tex]x[/tex]°

[tex]x[/tex]° = 540° - 409°

[tex]x[/tex]° = 131°

Answer:

115

Step-by-step explanation:

It should equal 115 degrees.

Answer:

≈ 66.5 m

Step-by-step explanation:

Using the sine ratio in the right triangle

sin12° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{d}{320}[/tex] ( multiply both sides by 320 )

320 × sin12° = d , then

d ≈ 66.5 m ( to 1 dec. place )

[tex]X\leq 1[/tex]

Because the line show X is 1 or less.

Answer:

X [tex]\leq[/tex] 1

Step-by-step explanation:

Since the dot is solid that means it includes 1

and since the line is going towards negative infinity that is why it is less than

So X is less than or equal to 1 which is the first answer

Incorrect measurement

Step-by-step explanation:

Given

Shape: Triangle

Length: 22in, 10in and 11in

Required: Determine if the measurements are correct

For the measurement of a triangle to be true, the sum of any 2 sides must be greater than the length of the third side.

i.e.

[tex]22 + 10 > 11[/tex] --- True

[tex]22 + 11 > 10[/tex] --- True

[tex]11 + 10 > 22[/tex] --- False

Since all three conditions are not true, then the measurements are incorrect

4,4,5,6,7

5,5,6,6,8

Step-by-step explanation:

mode = n

median= n+1

mean = n+2

Range = n+3

let sets:

a,b,c,d,e

mode = n, at least two of them are the same and equal to n

n,n,c,d,e

median belong to the set, in ascending order:

n,n,n+1,d,e

which means d,e ≥ n+1, d≠e

mean is n+2

5(n+2)=n+n+n+1+d+e

2n+9=d+e

Assume e is the maximum:

Range is n+3:

e-n=n+3

e=2n+3

d=6≥n+1

n≤5,

Set is n,n,n+1,6,n+3
