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]

Answer:

Step-by-step explanation:

just add all the sides. since it’s a rectangle, you there is 2 sides that’s 3ft long and that are 6ft long. so you would do 3+3+6+6

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:

missing angle = 41, b. 45, c. 72

Step-by-step explanation:

A circle has 360 degrees, so add all of the existing angles

48+45+129+97 = 319 and 360-319 = 41

25/200 = 12.5% so 12.5% of 360 = .125x360 = 45

Sector 129 represents 129/360 = 35.83% so 200x.3583=72 cars

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

Answer:

the third one

Step-by-step explanation:

bc like there are 2 boxes of 1 and 5 boxes of 1/6 so thats already 2 and 5/6 which applies to all of them. then there is 1 box of 1 and 2 boxes of 1/3 so thats 1 and 1/3 which applies to all of them also but when you make them have the same denominator you get 2 and 5/6 + 1 and 4/6 which deletes the second one. When you add you should get the same denominator so that deletes the first one so then you simplify that and the fraction should still be equal to the unsimplified fraction so you should get 4 and 1/2 if that makes sense

Answer:

y = 2/5x + 33/5

Step-by-step explanation:

(-9,3) and (1,7)

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

m=(7-3)/(1+9)

m=4/10

m = 2/5

y - y1 = m(x - x1)

y - 3 = 2/5(x + 9)

y - 3 = 2/5x + 18/5

y = 2/5x + 33/5

Answer:

Population of wolves in 2016 = 23

Step-by-step explanation:

Equation of the line of best fit has been given as,

y = 1.5x - 1

Here, y = population of a pack of wolves

x = duration (in years) since year 2000

Duration between year 2000 and 2016 = 16 years

Now we substitute the value x = 16 in the equation of line of best fit,

y = 1.5(16) - 1

y = 24 - 1

y = 23

Therefore, population of wolves in 2016 = 23

Answer:

3,3,4,6,6

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

n+1≤6≤n+3

2) they say make it unlikey that a blue box will be picked.. so color in one box

3) now don't color any of the boxes.. so no matter which boxes is picked.. there isn't any blue ones. :)

Answer:

There are 25 yellow flowers.

Step-by-step explanation:

The ratio is yellow/all and 5/9.

We know that all the flowers in total equal 45, which is a multiple of 9.

So 45 divided by 9 = 5.

So all I had to do was multiply 5/9 times 5/5.

So then we get the ratio of 45 total flowers with 25 yellow flowers.
