Using proportions, it is found that the cost per ounce is of $0.8.
What is the missing information?The missing information is the number of ounces in the balm, that is of 20.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
The cost per ounce is given by the proportion of the cost by the number of ounces, hence:
Cost: $16.Number of ounces: 20.Then:
$16/20 = $0.8.
The cost per ounce is of $0.8.

Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
Part B: Which function has a greater y-intercept? Justify your answer.
Answer: The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 -12 0 -6 1 0 g(x) g(x) = 2x + 6 Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
PART B: y=mx +b is slope intercept form of linear equation where m=slope and b =y intercept
slope for line for function f(x) =-5-(-1) / -1-0 =-5+1/-1=-4/-1=4
y = 4x+b
3=4(1)+b
3=4+b
-1 =b
y=4x-1
f(x)=4x-1 slope = 4
g(x)=2x -7 slope = 2
b) y intercept for f(x) is -1
and g(x) is -7
so f(x) is having greater y intercept

ABCD is a parallelogram.
The coordinates of point A are (2,5)
x = (4,0) and y = (5,12)
Find the coordinates of points B and C.
Answer:
B(6, 5), C(1, -7)
Step-by-step explanation:
A(2, 5)
From A to B, there is translation x, (4, 0).
Add 4 to A's x-coordinate, and add 0 to A's y-coordinate.
B(2 + 4, 5 + 0) = B(6, 5)
From C to B there is the translation y, (5, 12).
Since we are going from B to C, we undo translation y.
The translation from B to C is (-5, -12).
C(6 - 5, 5 - 12) = C(1, -7)

Step-by-step explanation:
Muriel can do the laundry in 3 hours working alone. Rea has more experience and can do the laundry in 2 hours working alone. How long will it take both people to do the laundry working together?
Here we have a problem of rates of work, where we want to find the rate at which two people would work together, so we can find the time it takes to complete a given job when these two work together..
We will find that they need to work for 6/5 hours to do the laundry together.
---------------------------------------
We know that:
Muriel can do the laundry in 3 hours.Rea can do the laundry in 2 hours.Then we can define:
M = rate at which Muriel works = 1/3hR = rate at which Rea works = 1/2hWhere the rates are computed as the quotient between 1 (1 total laundry completed) and the amount of time it takes to do it.
If they work together, the rate just adds up, so we will have:
rate = (M + R) = 1/3h + 1/2h
Now we need to write that as a single fraction, so we get:
rate = 1/3h + 1/2h = 2/6h + 3/6h = 5/6h
Now we can write an equation of the form:
rate*time = 1
Where the 1 again, means "one complete laundry done".
Then we have:
(5/6h)*T = 1
T = (6/5)h
This means that they need to work for (6/5) hours to do the laundry together.

184. A student estimated a mass to be 40 g. After carefully measuring, she
found the actual mass to be 45 g. What is the percent of error?
Answer:
\(\boxed {\boxed {\sf About \ 11 \%}}\)
Step-by-step explanation:
The formula for percent error is:
\(\% \ error = | \frac{measured \ value - actual \ value }{actual \ value} | *100\)
For this, the measured value is the estimation of 40 grams. The actual value is the true mass of 45 grams.
\(measured = 40 \ g \\actual = 45 \ g\)
\(\% \ error = | \frac{40 \ g - 45 \ g }{45 \ g } | *100\)
Solve the numerator.
40 grams - 45 grams = -5 grams\(\% \ error = | \frac{-5 \ g }{45 \ g } | *100\)
Divide.
\(\% \ error = | \frac{-5 \ g }{45 \ g } | *100\)
\(\% \ error = | -0.111111111| *100\)
\(\% \ error = 0.111111111*100\\\% \ error = 11.11111 \\\% \ error \approx 11\)
The percent error is about 11%
Find the value of X.
The calculated value of x in the circle is 15
How to calculate the value of xFrom the question, we have the following parameters that can be used in our computation:
The circle and the tangent lines
The sum of angles on the circumference of a circle is 360 degrees
So, the value of x can be calculated using
17x + (180 - 75) = 360
When evaluated, we have
17x = 255
Divide both sides by 17
x = 15
Hence, the value of x is 15

Pilar has 40 shells in her collection. She goes to the beach. She collects 6 more shells in the morning and 3 more shells in the afternoon. What is the percent change in Pilar's shell collection from the beginning of the day to the end? Show your work.
The percent change in Pilar's shell collection from the beginning of the day to the end is, 22.5%
What is the percentage?Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".
Given that,
Pilar has 40 shells in her collection.
She collects 6 more shells in the morning and 3 more shells in the afternoon.
The percent change in Pilar's shell collection from the beginning of the day to the end = ?
At the beginning of the day, Pilar has 40 shells.
In the morning, she collects 6 more shells, bringing her total to
= 40 + 6
= 46 shells.
Then, in the afternoon, she collects 3 more shells, bringing her total to
=46 + 3
= 49 shells.
To find the percent change in Pilar's shell collection from the beginning of the day to the end, we can use the formula:
percent change = (final value - initial value) / initial value * 100%
Plugging in the values we have:
percent change = (49 - 40) / 40 x 100%
percent change = 9 / 40 x 100%
percent change = 22.5%
Therefore, there is a 22.5% increase in Pilar's shell collection from the beginning of the day to the end.

how could you use the symmetry of the graph to find the zeros of the function?
Our vertex has an x-coordinate of 0, so the axis of symmetry for our function is x = 0. Now, let's consider the zeros of our function. Graphically, the zeros of a function are the x-coordinates of the points where the function crosses the x-axis. This occurs where y = 0.
Which ordered pair does NOT lie on the graph of the exponential function

I labeled them all on Desmos & they all seem to lie on it, which is why I need help.
The ordered pair does not lie on the graph of the exponential function
is (12, 0).
Option A is the answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To check whether an ordered pair lies on the graph of the exponential function f(x) = \(3(1/4)^x,\)
We need to substitute the values of x and y into the function and see if the equation holds true.
A. (12, 0)
Substituting x = 12 and y = 0 into the function, we get:
\(f(12) = 3(1/4)^{12} = 0.000002861\)
This does not equal y = 0, so (12, 0) does not lie on the graph of the function.
B. (-2, 48)
Substituting x = -2 and y = 48 into the function, we get:
\(f(-2) = 3(1/4)^{-2} = 48\)
This does not equal y = 48, so (-2, 48) does lie on the graph of the function.
C. (2, 3/16)
Substituting x = 2 and y = 3/16 into the function, we get:
\(f(2) = 3(1/4)^2 = 3/16\)
This equals y = 3/16, so (2, 3/16) does lie on the graph of the function.
D. (0, 3)
Substituting x = 0 and y = 3 into the function, we get:
\(f(0) = 3(1/4)^0 = 3\)
This equals y = 3, so (0, 3) does lie on the graph of the function.
Therefore,
The ordered pair does not lie on the graph of the exponential function
is (12, 0).

When we look at how many dramas have been rented you get 25, simply, you divide 125 by 25, therefore you should get 5, so now, we know that there is a 1/5 possibility for getting it but because its not 5/5.
