Answer:

B

Step-by-step explanation:

From the table B has a constant of proportionality between y and x of 1/5.

We need to find which table has a constant of proportionality between y and x of 1/5.

Constant of proportionality is the constant value of the ratio between two proportional quantities.

The equation for direct proportionality is y = kx, which shows as x increases, y also increases at the same rate.

Now, k=y/x

From table A:

k=4/5 ÷ 2

=2/5

k=14/5 ÷ 7

=2/5

k=24/5 ÷ 12

=2/5

From table B:

k=8/5 ÷ 8

=1/5

k=9/5 ÷ 9

=1/5

k=2/10 =1/5

From table C:

k=16/5 ÷ 3

=16/15

k=26/5 ÷ 5

=26/25

k=36/5 ÷ 7

=36/35

Therefore, from the table B has a constant of proportionality between y and x of 1/5.

multiply $28.5 by 40 to get how much she makes in a week= $1,140 multiply that by 52 because there are 52 weeks in a year and you get $59,280

The graph of the linear function y = 7.50x has a slope of 7.50 and a y-intercept is 0

The equation is given as:

y = 7.50x

The above equation is a linear equation

A linear equation is represented by y = mx + c

Where m represents the slope and c represents the y-intercept

By comparison, we have:

The slope is 7.50 and the y-intercept is 0

Answer:

33, 35, 37

Step-by-step explanation:

Let the tree consecutive odd integers be x, x +2 and x + 4

According to the given information:

Sum of the first and the third is 70

[tex] \therefore x + x + 4 = 70\\\\

\therefore 2x = 70 - 4\\\\

\therefore 2x = 66\\\\

\therefore x = \frac{66}{2}\\\\

\therefore x = 33\\\\

\implies x + 2 = 33 + 2 = 35\\\\

\& \hspace{25 pt}x + 4 = 33 + 4 = 37\\\\[/tex]

Thus, the three consecutive odd integers are 33, 35 and 37.

Verification: 33 + 37 = 70

Answer:

Suppose you want to frame a collage of pictures. You have a 9-ft strip of wood for the frame. What dimensions of the frame give you the maximum area for the collage? What is the maximum area?

A:

Perimeter = 2(L + W) 9 = 2(L+W) L+W = 4.5 L = 4.5-W Area = LW Area = (4.5-W)W A = 4.5W - W^2 You have a quadratic with a = -1 and b = 4.5 Maximum area occurs when W = -b/(2a) = 4.5/(2*-1) = 2.25  

Step-by-step explanation:

Dimension of the picture with 9ft strip of wood is

length = 2.25 ft  and width =2.25 ft

Given :

you want to frame a collage of picture with a 9ft strip of wood.

the perimeter of the frame is 9 ft

Perimeter of rectangle = 2(length +width )

Let 'l' be the length and 'w' be the width

[tex]Perimeter =2(l+w)\\9=2(l+w)\\Divide \; by \; 2\\l+w=4.5\\l=4.5-w[/tex]

Now we find the area

[tex]Area = length \cdot width \\Area= l \cdot w\\A= (4.5-w)(w)\\A=-w^2+4.5w[/tex]

Now we find out 'w' where area is maximum

[tex]w=-\frac{b}{2a} \\a=-1 and b=4.5\\w=-\frac{4.5}{2(-1)} =2.25[/tex]

Width =2.25 gives us maximum area

Now find out the length ,

[tex]Length = 4.5 -w\\w=2.25\\Length = 4.5-2.25=2.25[/tex]

Dimension of the picture is length = 2.25 ft  and width =2.25 ft

Answer:

y=(x+1)^2-7

Step-by-step explanation:

y=x^2+2x-6=x^2+2x+1-7

y=(x^2+2*1*x+1^2)-7

y=(x+1)^2-7

vertex form equation is y=a(x-h)^2+k

of equation y=ax^2+by+c

so a is 1

h is -1 because (x+1)=(x-(-1))

The probability P(A or B) is equal to 5/10 = 0.5

P(A or B) is the probability that a randomly selected student plays either basketball of soccer.

On the diagram, we can see that there are a total of 10 students, such that 2 play only basketball and 3 play only soccer.

P(A or B) is equal to the quotient between the number of students that play one of the sports (here we don't count the ones that play both sports) and the total number of students.

Then we have:

P(A or B) = (2 + 3)/10 = 0.5

Answer:

6%

Step-by-step explanation:

Since the volume of the cylinder V = πr²h where r = radius of cylinder and h = height of cylinder and h = 2r, we have that r = h/2.

Substituting r into v, we have

V = πr²h

V = π(h/2)²h

V = πh³/4

Now let ΔV be the error in the volume and Δh be the error in the height.

Since h is raised to the power of 3,

ΔV/V = 3Δh/h

multiplying both sides by 100, we have

ΔV/V × 100 = 3Δh/h × 100

So, we have

ΔV/V × 100 = 3 × Δh/h × 100

since Δh/h × 100 = percentage error in height = 2%, and ΔV/V × 100 = percentage error in volume,

ΔV/V × 100 = 3 × 2% = 6%

So, the percentage error in volume is 6 %

Answer:

x = 5

Step-by-step explanation:

Given that y is inversely proportional to x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of proportion

To find k use the condition when y = 25 , x = 4 , then

25 = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )

100 = k

y = [tex]\frac{100}{x}[/tex] ← equation of proportion

When y = 20, then

20 = [tex]\frac{100}{x}[/tex] ( multiply both sides by x )

20x = 100 ( divide both sides by 20 )

x = 5
