Answer:

k = $0.50

Step-by-step explanation:

The data that we have is:

Rocko paid: $12.50 for 25 tickets.

Louisa paid: $17.50 for 35 tickets.

Now, the question asks to find the constant of proportionality.

A proportional relation can be written as:

y = k*x

where k is the constant, and in this case, y is the price and x the number of tickets bought.

Then replacing with the values above, we have:

$12.50 = k*25

then:

k = $12.50/25 = $0.50

And the other data:

$17.50 = k*35

K = $17.50/35 = $0.50

So we have the same k in both cases, this means that the constant of proportionality is k = $0.50

i'm not all too familiar with the constant of proportionality, but both of the situations have a ratio of 0.5/1..

12.50/25 = 0.5/1

17.50/35 = 0.5/1

hopefully this can help you in some way! sorry if it doesn't

What kind of linear relationship can be represented using a table but not a function? Explain. (1 point)
O A horizontal line can be represented using a table but not a function because the slope is undefined
A vertical line can be represented using a table but not a function because the slope is undefined.
O A vertical line can be represented using a table but not a function because the slope is zero.
O A horizontal line can be represented using a table but not a function because the slope is zero

Answers

Answer:

The correct option is;

A vertical line can be represented using a table but not a function because the slope is undefined

Step-by-step explanation:

A function, f(x), representing a linear relationship can be presented as follows;

f(x) = m·x + c

Where;

m = The slope = Δy/Δx = (y₂ - y₁)/(x₂ - x₁)

c = The y-intercept

Whereby the line is a vertical line, x₂ = x₁ and x₂ - x₁ =

Therefore;

The slope of a vertical function, m =  (y₂ - y₁)/(x₂ - x₁) = (y₂ - y₁)/0 = ∞ from which we have;

f(x) = ∞·x + c = ∞ which is undefined and the vertical line can only be represented using a table but not a function because the slope is undefined

(HELP PLEASE!! answer all the questions) Mr. Smith decorates his U.S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 34feet long.
Each president's picture is 6 inches wide.

If the pictures are placed side by side on either side of the window, how many pictures can he fit on this wall?

Answer the questions to solve this problem.


1. How many feet long is the space Mr. Thuman wants to fill with pictures? Explain how you know.

Write your answer in the space below.






2. Convert this length to inches. (There are 12 inches in 1 foot)

Write your answer in the space below.









3. How many pictures will Mr. Thuman use? Explain how you found your answer.

Write your answer in the space below.









4. How would your answer change if the pictures were 10 inches wide? Explain.

Write your answer in the space below.

Answers

9514 1404 393

Answer:

4.00 feet48 inches8 pictures4 pictures

Step-by-step explanation:

1. The available wall space is the difference between the length of the wall and the length of the window:

  9.75 ft - 5.75 ft = 4.00 feet

__

2. At 12 inches per foot, this is ...

  (4 ft)(12 in/ft) = 48 in

__

3. If the pictures are 6 inches wide, Mr. Smith can use ...

  (48 in)/(6 in/picture) = 8 pictures

__

4. If the pictures are 10 inches wide, Mr. Smith can use ...

  (48 in)/(10 in/picture) = 4.8 pictures

There is room for 4 pictures. Space for a fraction of a picture is not useful. This number is even, so 4/2 = 2 pictures can be placed on either side of the window.

A formula for finding the perimeter of a rectangle is P=2L +2W . if you know the perimeter (P) and the length (L) of a rectangle, which formula can you use to find the width (W)?

Answers

The original equation is
P=2L+2W

We will just switch the unknowns around. To find width (W), we must isolate it in the equation by moving 2L over to the other side:

P-2L=2W

(P-2L)/2=W

W=(P-2L)/2

There you go!!

Read and understand the situation below, and make a complete plan to solve Mang Jose’s problem.

Mang Jose wants to paint the exterior of his house. He needs to know how many gallons of paint he would need. So, he asks his friend Juan to help him, according to Juan one (1) gallon of paint can cover an area of 250 square feet. Help Mang Jose prepare a budget for his project if his house exterior is 2700 square feet. Do a research on the different prices of one (1) gallon of paint depending on its brand name and choice of colors. Make a proposal budget for three (3) different colors of paint with its corresponding brand name.

Answers

Explanation:

Let's assume these are the different prices of one (1) gallon of paint for three different brand name and choice of colors:

1. Delux brand: Red = $19 per gallon

2. Golden sun: White = $15 per gallon

3. Luxury: Green = $20 per gallon.

Based on the data above, Mang Jose's budget could be drafted:

1. if he chooses the Delux brand/color red, then he will need approximately 11 gallons of the paint (2700/250 square fit) = 10.8, which would cost = $209 (11*$19).

2. if he chooses the Golden sun brand/color white then he will need approximately 11 gallons of paint  (2700/250 square fit) = 10.8, which would cost = $165 (11*$15).

3. if he chooses the Luxury brand/color green then he will need approximately 11 gallons of paint  (2700/250 square fit) = 10.8, which would cost = $220 (11*$20).
