You bought a blu-ray that cost $28.68 before tax. How much did you have to pay once the 7% sales tax was factored in?
Answers
Answer:
You had to pay $30.69 after the sales tax factored in.
Step-by-step explanation:
First step is to find 7% of $28.68.
The answer to that is the sales tax, therefore making the sales tax $2.01.
Finally, you have to add $2.01 to $28.68 to get a total of $30.69, your final answer.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Which term best describes the graph of y = –2?
increasing
decreasing
constant
positive
Answers
Answer:
It would be constant.
Step-by-step explanation:
Since there is no x value, the line will have no slope and just be horizontal about y= -2.
If we draw the graph we will see that the function is a straight line parallel to the x-axis.
The graph y = -2 is best described as a constant function.
Option C is the correct answer.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
A function:
y = -2
To graph the function we will find the coordinates of the function y = -2.
For x = 0,
y = -2
For x = 1,
y = -2
For x = 2,
y = -2
For x = 3,
y = -2
We will see that for all x values the y value is -2.
If we draw the graph we will see that the function is a straight line parallel to x-axis.
Thus,
The graph y = -2 is best described as a constant function.

Becky takes out a loan for $5,000. She plans to repay the loan in 8 years. The interest rate is 7.3% compounded annually. How much will she have to pay in interest?
Answers
(0.073 x 5,000) x 8
$2920 is our total interest :)
Answer:
$3785.53
Step-by-step explanation:
You want the interest amount due at the end of 8 years on a $5000 loan at 7.3% compounded annually.
Future valueThe amount due is multiplied by (1 +0.073) each year. After 8 years, the amount due will be ...
5000(1.073^8) ≈ 8785.53
Of that, 5000 is the principal amount, so the remainder is interest.
interest = $8785.53 -5000
interest = $3785.53
Becky will have to pay $3785.53 in interest.

Step-by-step explanation:
So the fraction of the amount of balls Kayla hit is 19/20 if you multiply 19 and 20 by five, you will get the fraction 95/100, so Kayla hit 95% of the balls pitched to her.
Answer:
95%
Step-by-step explanation:
Percentage is written as the favourable outcomes, divided by the total outcomes
The favourable outcome here is the 19 hits
The total outcomes is 20
Now, we divide 19/20
19/20 = 0.95 = 95%
Another way is to multiply the fraction by 5/5 to get 95/100
Since percentage is based on 100, you can take 95 as your percentage

Using the line of best fit that you found in 2, approximate how tall is a person whose arm span is 66 inches?
According to your line of best fit, what is the arm span of a 74-inch-tall person?
Answers
Answer:
Here's what I get.
Step-by-step explanation:
1. Representation of data
I used Excel to create a scatterplot of the data, draw the line of best fit, and print the regression equation.
2. Line of best fit
(a) Variables
I chose arm span as the dependent variable (y-axis) and height as the independent variable (x-axis).
It seems to me that arm span depends on your height rather than the other way around.
(b) Regression equation
The calculation is easy but tedious, so I asked Excel to do it.
For the equation y = ax + b, the formulas are
\(a = \dfrac{\sum y \sum x^{2} - \sum x \sumxy}{n\sum x^{2}- \left (\sum x\right )^{2}}\\\\b = \dfrac{n\sumx y - \sum x \sumxy}{n\sum x^{2}- \left (\sum x\right )^{2}}\)
This gave the regression equation:
y = 1.0595x - 4.1524
(c) Interpretation
The line shows how arm span depends on height.
The slope of the line says that arm span increases about 6 % faster than height.
The y-intercept is -4. If your height is zero, your arm length is -4 in (both are impossible).
(d) Residuals
\(\begin{array}{cccr}&\textbf{Arm Span} & \textbf{Arm Span}&\\\textbf{Height/in} &\textbf{Actual} & \textbf{Predicted}&\textbf{Residual}\\25 & 19 & 22.3 & -3.3\\40 & 41 & 38.2 & 2.8\\55 & 51 & 54.1 & -3.1\\65 & 67 & 62.6 & 4.4\\ \end{array}\)
The residuals appear to be evenly distributed above and below the predicted values.
A graph of all the residuals confirms this observation.
The equation usually predicts arm span to within 4 in.
(e) Predictions
(i) Height of person with 66 in arm span
\(\begin{array}{rcl}y& = & 1.0595x - 4.1524\\66 & = & 1.0595x - 4.1524\\70.1524 & = & 1.0595x\\x & = & \dfrac{70.1524}{1.0595}\\\\& = & \textbf{66 in}\\\end{array}\\\text{A person with an arm span of 66 in should have a height of about $\large \boxed{\textbf{66 in}}$}\)
(ii) Arm span of 74 in tall person
\(\begin{array}{rcl}y& = & 1.0595x - 4.1524\\& = & 1.0595\times74 - 4.1524\\& = & 78.4030 - 4.1524\\& = & \textbf{74 in}\\\end{array}\\\text{ A person who is 74 in tall should have an arm span of $\large \boxed{\textbf{74 in}}$}\)

The area of a rectangular window is 6734 cm².
If the length of the window id 91 cm, what is its width?
Width of the window [] cm.
Answers
(A):88
(B):74
Explanation:
For (A), first multiply 77 by 2 then subtract from 330
77x2=154
330-154=176
For (A), second divide 176 by 2
176/2=88
Length=88
For (B), divide 6734 by 91
6734/91=74
Hope this helps!
Answer:
(a) 88 m
(b) 74 cm
Step-by-step explanation:
You want the length of a garden with a perimeter of 330 m and a width of 77 m, and you want the width of a window with an area of 6734 cm² and a length of 91 cm.
(a) PerimeterThe perimeter of a rectangle is given by the formula ...
P = 2(L +W)
Filling in the given values, we can find the unknown.
330 = 2(L +77)
165 = L +77 . . . . . . . divide by 2
165 -77 = 88 = L
The length of the garden is 88 meters.
(b) AreaThe area of a rectangle is given by the formula ...
A = LW
Filling in the given values, we can find the unknown.
6734 = 91W
6734/91 = 74 = W
The width of the window is 74 cm.
