The best description of the given inequality is;
Felicia has 29 buttons in her collection. She will collect 12 new buttons every year. Felicia collects buttons for k years. For what values of k will Felicia have at least 120 buttons?
Hence, Option B is true.
What is inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
The inequality is given as;
⇒ 120 ≤ 12 k + 29
It can be written as;
12k + 29 ≥ 120
Now, We have;
A constant term = 29
And, Variable with number = 12k
Which is multiple of the number of buttons collected and the number of years k.
The sign is ''greater than equal'' to with 120, that's mean 'at least 120'
So, The best description of the given inequality is;
Felicia has 29 buttons in her collection. She will collect 12 new buttons every year. Felicia collects buttons for k years. For what values of k will Felicia have at least 120 buttons?
Hence, Option B is true.

Let g(x)=3 x+2 and f(x)=x-2 / 3 . Find each value.
(f⁰f)(0)
A composite function exists as a function that depends on another function. The value for (f⁰f)(0) = - 4/3
What is meant by composition function?In mathematics, function composition exists as an operation ∘ that takes two functions f and g, and has a function h = g ∘ f such that h(x) = g. In this operation, the function g exists used to the result of applying the function f to x.
Function composition is a mathematical procedure where two functions, f, and g, are taken and a function, h = g ∘ f, is produced such that h(x) = g(f(x)). The function g exists used in this operation on the outcome of applying the function f to x.
Let the two functions be g(x) = 3x + 2 and f(x) = x - 2/3
Now, (f⁰f)(x) = f[f(x)]
f(x) = x - 2/3
(f⁰f)(x) = f( x - 2/3)
simplifying the above equation, we get
(f⁰f)(x) = (x - 2/3) - 2/3
(f⁰f)(0) = - 2/3 - 2/3
(f⁰f)(0) = - 4/3
Therefore, the value of (f⁰f)(0) = - 4/3.

A=P(1+in)
P=900
i=0.03

A=?
The value of A is 954
According to the question we have been given that
The equation to be used is : A = P(1+in)
The values we have been given are ;
P = 900
i = 0.03
n = 2
We need to find the value of A. So to find the value of A we have to put the required values in the equation given to us. Thus,
A = 900(1+0.03*2)
We will solve according to the BODMAS rule that is we have to first solve the bracket terms.
A = 900(1 + 0.06)
A = 900*1.06
A = 954

Step-by-step explanation:

This is not a true sequence. It just has the same things done to the numerator as to the denominator.
The numerator (top part of the fraction).
Add 3 to the previous numerator's top
So 3 + 3 = 6 which is the numerator of the second term.
15 + 3 = 18 which is the numerator of the seventh term.
So the numerator of the 4th term is 9 + 3 = 12
The Denominator
The difference there is 5
So 21 + 5 = 26
The answer is
12/26
This reduces down to 6/13

Ryan and Aqil had 352 stickers altogether. After Ryan lost 25% of his stickers, the ratio of Ryan's stickers to Aqil's stickers was 9:4. How many stickers did Aqil have?
Aqil have 88 stickers.
Let Ryan have x stickers initially. Then Aqil will have (352-x) stickers. Ryan lost 25% of his stickers i.e., x-(25% of x)
= x- 25x/100
= x-x/4
= 3x/4
After Ryan lost 25% of his stickers, the ratio of Ryan's stickers to Aqil's stickers was 9:4 i.e.,
3x/4 : (352-x) = 9 : 4
⇒ 3x/4/(352-x) = 9/4
⇒3x/4 x 4 = 9 x (352-x)
⇒3x = 3168-9x
⇒3x+9x = 3168
⇒12x = 3168
⇒x = 3168/12
⇒x = 264
∴ Ryan have 264 stickers of the total 352 stickers and Aqil will have (352-x) i.e., 88 stickers.
Hence, Aqil have 88 stickers out of the 352 stickers.

A business owner made a survey where he ask his customers150 what do they like the most between a fish and meat and he got this data 85 like meat 125 like fish 70 like both fish and meat 1 what is the probability for a customer to pick at least one item?
Taking into account the definition of probability, the probability for a customer to pick at least one item is 14/15.
Definition of ProbabitityProbability is the possibility that a phenomenon or an event will happen, given certain circumstances and it is expressed as a percentage.
The probability of any event A is defined as the ratio between the number of cases in which event A may or may not occur and the total number of possible cases. This is called Laplace's Law:
P(A)= number of favorable cases÷ total number of posible cases
Union of eventsThe union of events, AUB, is the event formed by all the elements of A and B. That is, the event is verified when one of the two, A or B, or both occurs and it is read as "A or B".
The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:
P(A∪B)= P(A) + P(B) -P(A∩B)
where the intersection of events, A∩B, is the event formed by all the elements that are, at the same time, from A and B.
Probability for a customer to pick at least one itemIn first place, let's define the following events:
M: The event that a customer like meat.F: The event that a customer like fish.So you know:
P(M)= 85÷150= 17/30P(F)= 125÷150= 5/6P(F and R)= P(F∩R)= 70÷150= 7/15In this case, considering the definition of union of events, the probability for a customer to pick at least one item is calculated as:
P(M∪F)= P(M) + P(F) -P(M∩F)
P(M∪F)= 17/30 + 5/6 -7/15
P(M∪F)= 14/15
Finally, the probability for a customer to pick at least one item is 14/15.

The transformations needed to sketch the graph of [tex]h(x) = \sqrt[3]{1 - x}[/tex] are described as follows:
Starting with the graph of the basic function [tex]y = \sqrt[3]{x}[/tex], horizontally shift the graph right one unit, and then reflected the graph about the x-axis.
What is a transformation in a function?A transformation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).
Examples are shift left, shift right, shift down, shift up, vertical stretching, horizontal stretching, vertical compression, horizontal compression, reflection over the x-axis, reflection over the y-axis, and rotations by a determined amount(in degrees). All these translations have predetermined rules that we apply to the figures.
The parent cube root function is given by:
[tex]y = \sqrt[3]{x}[/tex]
To have x -> x - 1, we reflect the function over the y-axis, hence:
[tex]y = \sqrt[3]{-x}[/tex]
To have -x -> 1 - x, we shift it one unit right, hence:
[tex]h(x) = \sqrt[3]{1 - x}[/tex]
The order of the transformations can be reversed, i. e., shift right then reflection.
Thus the correct statement to sketch the graph is given by:
Starting with the graph of the basic function [tex]y = \sqrt[3]{x}[/tex], horizontally shift the graph right one unit, and then reflected the graph about the x-axis.

In a bake sale, you recorded the number of muffins sold and the amount of sales in a table as shown.
a. What is a function that relates the sales and the number of muffins?
The function that relates the sales and the number of muffins is :
S = 2.5 m
What is the sales amount ?The sales amount can be find by the total sales. That is , if there are n products to sell and selling amount is x rs. then we can easily find the total sales by multiplying them and by this total sales we can easily find the number of items sold per units and vice versa.
In the question given,
amount (A) = $ 250.00
Now take any of two values from table ,
Choose any two points and calculate the slope:
slope = [tex]\frac{50 - 20}{20 - 8}[/tex] = 2.5
thus, y = 2.5x
Hence we can say the function that relates the sales and the number of muffins is :
S = 2.5 m
where, S = sales amount
m = number of muffins to be sell
