in preparation for moving into his first apartment after college, Winston goes on a shopping spree and spends $984 on furnishing, decorations, and other home goods. Sales tax in his area is 8.19%, and none of the items he buys are tax exempt. What will Winston’s total bill be at the cash register? Round to the nearest cent
Winston's total bill at the cash register is $1064.59
Sales tax for the items purchased is $80.59
Given,
The price for the items Winston purchased = $984
Sales tax in Winston's area = 8.19%
We have to find Winston's total bill at the cash register:
Total amount = Price of the items + sales tax amount
Sales tax amount = 8.19% of price of items
Sales tax amount = (8.19/100) × 984
Sales tax amount = $80.59
Now,
Total bill amount = Price of the items + sales tax amount
Total bill amount = 984 + 80.59
Total bill amount = 1064.59
Therefore, Winston's total bill at the cash register is $1064.59

Question 5 ? Question What does the point (6,0) represent? O the length of time it takes for the height of the plant to reach 72 centimeters O the initial amount of plant food O the amount of plant food used each day O the length of time it takes for Ryan to use all the plant food
The point (6,0) represent the length of time it takes for Ryan to use all the plant food
What is Time ?
Time is a continual and continuous series of events that take place one after another, from the past through the present and into the future. The duration of events or the gaps between them can be measured, compared, or even ordered using time.
The location and value of x at which the function represented by f(x) equals zero are known as the x-intercept.
The height of the bean sprout and the quantity of plant food added were both measured, per the information given.
Given the observational aspect of the experiment, we know that the function of the variable y = f(x) is the height of the bean sprout, and the variable x, which may be chosen by the researcher, is the amount of the additional plant food.
As a result, the x-intercept, which represents the experiment's starting position (represented by the natural numbers of y = 0), shows how much plant food was initially added to the soil.
Hence, The point (6,0) represent the length of time

The point (6, 0) represents the initial amount of plant food, which is 0 at this point.
When representing a point in the form (x, y), the x-coordinate typically represents a quantity or value on the horizontal axis, while the y-coordinate represents a quantity or value on the vertical axis.
The point (6,0) means that the x-coordinate is 6, which corresponds to a specific value or measurement along the horizontal axis.
Since the context of the question refers to plant food, the x-coordinate of 6 likely represents a measurement related to the amount of plant food.
The y-coordinate, in this case, is 0, indicating that there is no height or value represented on the vertical axis.
Therefore, (6, 0) represents the initial amount of plant food, which is 0 at this point.

What is the mathematical operation?An operation, often known as "operand" or "argument," is a function in mathematics that converts zero or more input values into a clearly defined output value. The operation's arity is determined by number of operands.
Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are operations that are most frequently studied. A constant is operation with arity zero, often known as a nullary operation. An example of an operation of arity 3, sometimes known as ternary operation, is the mixed product.
The arity typically assumed to be limited. The "typical" operations of finite dimensionality are referred to finiteary operations when infinitary operations are taken into consideration.
Similar to an operation, but with partial function in place of a function, is the definition of a partial operation.

decreases at a rate of 2 cubic meters per minute, find the rate of change of an edge of the cube when the volume is exactly 27 cubic meters.
The rate of change of an edge of the cube is 0.074 m/min.
What is the rate of change of volume of cube?The rate at which the volume of the cube changes is calculated as follows;
dv/dt = 2 m³/min
where;
v is the volume of the cubeThe length of edge of the cube will be denoted with a, and it is related to the volume of cube in the following equation.
v = a³
a = v^¹/₃
where;
a is the length of the edgeThe change in the edge with volume;
da/dv = 1/3 (1/v)^2/3
The change in edge of the cube with time is given as;
da/dt = da/dv . dv/dt
da/dt = 1/3 (1/v)^2/3 x 2 m³/min
da/dt = 1/3 (1/27)^2/3 /m² x 2 m³/min
da/dt = 1/27 x 2 m/min

In mathematics, creating equations from word descriptions is referred to as a "word problem."
For example, in the question, equations are expressed in words and then rewritten in figures, which is the preferred way to write equations.
The equation is rewritten in words and solved as below.
How to write and solve the equation
Given expression is,
[tex](\frac{-1}{8}*r-5-\frac{1}{6} *r)-(\frac{-6}{8} *r+3)[/tex]
solving the equation:
= [tex](\frac{-1}{8} *r-5-\frac{1}{6} *r)-(\frac{-6}{8} *r+3)[/tex]
= [tex](\frac{-r}{8} -5-\frac{r}{6} )-(\frac{-6r}{8} +3)[/tex]
opening the parenthesis leads to change of signs as follows
= [tex]\frac{-r}{8} -5-\frac{r}{6} +\frac{6r}{8} -3[/tex]
= [tex]\frac{-r}{8} -\frac{r}{6} +\frac{6r}{8} -5-3[/tex]
= [tex]\frac{-3r-4r}{24}+\frac{6r}{8} -8[/tex]
= [tex]\frac{-7r}{24} +\frac{6r}{8} -8\\[/tex]
= [tex]\frac{-7r+18r}{24} -8[/tex]
= [tex]\frac{11r}{24} -8[/tex]
= [tex]\frac{11}{24} *r+(-8)[/tex]
Therefore the correct answer is option D which is 11 over 24 times r plus negative 8.

What is a graph?In mathematics, and more specifically in the graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related". The objects correspond to the mathematical abstractions called vertices (also called nodes or points) and each of the related pairs of vertices is called an edge (also called link or line). Typically, a graph is depicted in the diagrammatic form as a set of dots or circles for the vertices, joined by lines or curves for the edges. Graphs are the one of the objects of study in discrete mathematics.
Edges may be directed or undirected. For example, if the vertices represent people at party, and there is an edge between two people if they shake hands, then this graph is undirected because any person A can shake hands with person B only if B also shakes hands with A. In the contrast, if an edge from a person A to a person B means that A owes money to B, then this graph is directed, because owing money is not necessarily reciprocated.
Graphs are basic subject studied by graph theory. J. J. Sylvester was the first to use the word "graph" in this context in 1878 due to the direct relation between mathematics and chemical structure (what he called a chemico-graphical image).

The shortest possible time is 15 minutes.
It takes 10 minutes to fry one steak - 5 minutes from each side. Two steaks can fit on a pan. What is the shortest possible time to fry 3 steaks?
If I go with the conventional way then I can fry two steaks together taking ten minutes and then I can fry the third one in another ten minutes. So total time 20 minutes.
Assuming that I have only one pan and three steaks to fry. We can even use unitary method .
I will put two steaks in the pan then after 5 minutes I will take out one steak and put the other steak while I will flip the steak which is still in the pan. So in first ten minutes I have only one steak ready. Then I will flip the newly added steak in the pan and put the half side fully cooked steak also in the pan. So in this way in the coming five minutes my other two steaks will also get cooked. Total time taken=5+5+5=15 minutes.
