Melanie buys 2 shells for $0.80. Rosi buys 3 shells for $1.20. Carlos buys 4 shells for $1.60. Use the graph to determine whether there is a proportional relationship between the number of shells and their cost. If so, what does the constant of proportionality mean in this situation? Use the drop-down menus to show and explain your answer.
Answers
Answer:
There's a proportion relationship between number of shell and their cost
Step-by-step explanation:
The graph is not given.
However, I've added the appropriate graph as an attachment.
From this, point....
I'll show that the cost and number of shells as given in the question are proportional.
Represent cost with y and number of shells with x
x = 2 when y = 0.8
x = 3 when y = 1.2
x = 4 when y = 1.6
Divide each value of y by x to get the constant of proportion (r).
r = y/x
r = 0.8/2 = 0.4
r = 1.2/3 = 0.4
r = 1.6/4 = 0.4
Notice that the values of r remain constant.
Hence, there's a proportion relationship between both
And what this rate represent is that:.the cost of shell changes at a constant rate when the number of shell is changes.
The proportionality constant is same means that the cost of shell changes at a constant rate when the number of shells changes.
Given :
Melanie buys 2 shells for $0.80.Rosi buys 3 shells for $1.20.Carlos buys 4 shells for $1.60.The following steps can be used to determine there is a proportional relationship or not between the number of shells and their cost:
Step 1 - First determine the value of x and y from the given data.
Points - (2,0.8), (3,1.2), and (4,1.6)
Step 2 - Now, divide y by x in order to determine the proportionality constant.
[tex]r = \dfrac{0.8}{2} = 0.4[/tex]
[tex]r'=\dfrac{1.2}{3}=0.4[/tex]
[tex]r" =\dfrac{1.6}{4}=0.4[/tex]
Step 3 - Observe that the values of r, r', and r" are the same. Therefore, there is a proportional relation between them.
The proportionality constant is same means that the cost of shell changes at a constant rate when the number of shells changes.

Beyonce’s fish tank holds 180 gallons of water and is leaking at a rate of 8 gallons per day. Jay Z’s fish tank holds 160 gallons of water and is leaking at a rate of 6 gallons per day. At how many days will the two fish tanks have the same amount of water in them?
Justin Bieber’s sand castle is 180cm tall but the wind is blowing away sand at a rate of 8cm per minute. Taylor Swift’s sand castle is 160cm tall and she it adding sand to it at a rate of 6cm per minute. After how many minutes will their sand castles be the same height?
Answers:
1) 160 + 8x = 180 + 6x
2) 160 + 6x = 180 - 8x
Answers
The fish tank problem:
x = # of days
180 - 8x = 160 - 6x
Add 8x to both sides and subtract 160 from both sides.
20 = 2x
Divide both sides by 2
10 = x
It will take 10 days for the fish tanks to have the same amount of water in them.
The sand castle problem:
x = # of minutes.
180 - 8x = 160 + 6x
Add 8x to both sides and subtract 160 from both sides.
20 = 14x
Divide both sides by 14
x = 10/7 mins
After 10/7 mins their sand castles will be the same height

$203,333
$268,466
$459,400
Answers
Answer:
$203,333
Step-by-step explanation:
Computation for the break-even in sales dollars for Division Q
First step is to compute the Segment Contribution Margin ratio
Using this formula
Segment Contribution Margin ratio = Segment contribution margin ÷ Segment sales
Let plug in the formula
Segment Contribution Margin ratio= $ 175,980÷ $ 419,000
Segment Contribution Margin ratio= 0.42
Last step is to find the break-even in sales dollars for Division Q using this formula
Break-even in sales dollars = Segment traceable fixed expenses ÷ Segment Contribution Margin ratio
Let plug in the formula
Break-even in sales dollars= $85,400÷ 0.42
Break-even in sales dollars=$203,333
Therefore the break-even in sales dollars for Division Q is $203,333

A local little league has a total of 60 players, of whom 20% are left-handed. How many left-handed players are there?
Answers
Answer:
There are 12 left-handed players in the league
Step-by-step explanation:
To find the value of the percentage of a given number, change the percentage at first to decimal by divide it by 100, then multiply the decimal by the number.Ex: 5% of 50 ⇒ 5% = [tex]\frac{5}{100}[/tex] = 0.05 ⇒ 5% × 50 = 0.05 × 50 = 2.5Let us solve the problem
∵ A local little league has a total of 60 players
∵ 20% of them are left-handed
→ Find 20% of 60
∴ The number of left-handed players = 20% × 60
→ Change 20% to a decimal
∵ 20% = [tex]\frac{20}{100}[/tex] = 0.20
∴ The number of left-handed players = 0.20 × 60
∴ The number of left-handed players = 12
∴ There are 12 left-handed players in the league

Kelsey has designed the pendant shown, that hangs from a chain. She makes pendants by bending silver wire into circles. The design connects one circle made from a wire 6 cm long to a second circle made from a wire 8 cm long. She plans to sell the pendants at a craft fair, and her goal is to make a minimum profit of $50 at the fair. Part A The height of the pendant is determined by using the formula for the circumference of a circle, C = id. Find the total height of the pendant design from top to bottom in terms of it. Then find the height rounded to the nearest tenth of a centimeter. Use 3.14 for T.
Answers
Answer:
4.4cmStep-by-step explanation:
in this problem we are expected to solve for the diameter of each circle pendant and add them to get the height of the complete pendant.
we know that the circumference is given as
C=πd
for the small circle
C=6cm
6=3.142d
d=6/3.142
d=1.9cm
for the big circle
C=8cm
8=3.142d
d=8/3.142
d=2.5cm
the height then is 1.9+2.5=4.4cm

Answers
Answer:

Step-by-step explanation:
Given
[tex]Distance = 345\ miles[/tex]
[tex]Time = 5\ hours\ 45\ minutes[/tex]
Required
Determine the average speed
This is calculated as thus:
[tex]Average\ Speed = \frac{Distance}{Time}[/tex]
Convert time to hour:
[tex]Time = 5\ hours\ 45\ minutes[/tex]
[tex]Time = 5\ hours + \frac{45}{60}\ hour[/tex]
[tex]Time = 5\ hours + \frac{3}{4}\ hour[/tex]
[tex]Time = \frac{20 + 3}{4}\ hours[/tex]
[tex]Time = \frac{23}{4}\ hours[/tex]
[tex]Time = 5.75\ hours[/tex]
[tex]Average\ Speed = \frac{Distance}{Time}[/tex]
[tex]Average\ Speed = \frac{345}{5.75}[/tex]

The graph represents a function. Find the input value corresponding to an output of 2.
Answers
Answer:
The input value is -2
Step-by-step explanation:
Input values are x-values plotted on the horizontal axis (x-axis) while the output values are plotted on the vertical axis (y-axis).
What we are simply asked to do is to determine what the value of x is on the x-axis, that corresponds to the y-value of 2 on the y-axis.
Thus, when y = 2 on the x-axis, x = -2 on the x-axis.
The input value of -2, corresponds to the output value of 2.
Answer:
-2
Step-by-step explanation:
Input values are x-values plotted on the horizontal axis (x-axis) while the output values are plotted on the vertical axis (y-axis).
We are expected to determine what the value of x is on the x-axis, that corresponds to the y-value of 2 on the y-axis.
When y = 2 on the x-axis, x = -2 on the x-axis.
The input value of -2, corresponds to the output value of 2.
g Suppose you are rasterizing a triangle with vertices (1, 1), (5, 1), and (2, 9), and the intensity values (e.g., redness) of those vertices are 5, 9, and 14, respectively. Using the linear interpolation scheme, what is the intensity value of an interior point at (3, 5)? Show all your work.
Answers
Answer:
6.333
Step-by-step explanation:
Our triangle vertices are
(1,1)(5,1)(2,9)
We are to perform interpolation at point(3,5)
x and y values are interpolated
On vertices (5,1)(2,9)
x = 3
x1 = 5
X2 = 2
Y1 = 1
Y2 = 9
Formula for interpolation
Y = [y1+(x-x1)(y2-y1)]/x2-x
Y = 1+(3-5)(9-1)/2-5
Y = 1+[-2*8/-3]
Y = 1+16/3
From here we use use LCM to get:
19/3 = 6.333
