Jonae gets paid $16.50 an hour working at a furniture store. She also gets paid 20% of all of the store's furniture sales each week. This week, the store made $600 on a table and $400 on chairs. If Jonae worked 40 hours this week, how much will she be paid?
Answer:
$860
Step-by-step explanation:
Jonae makes $16.50 an hour and worked 40 hours. Multiply the hours worked by the amount of money she earned.
$16.50 × 40 = $660
The stored made $600 on a table and $400 on chairs, which, in total, is $1000. Since Jonae gets paid 20% of all of the furniture sales, multiply the total sales by the percentage.
$1000 × 0.2 = $200
Add together the earnings she made per hour and the earnings she made from the furniture store's sales.
$660 + $200 = $860

How do you Graph: -3x – 2y = -8
Answer:
I hope this helps!
Answer:
y = -2/3x +4 --> y = mx+b form
Step-by-step explanation:
-3x-2y = -8 --> add 3x to both side
-2y = 3x-8 --> divide by -2 on both side
y = -2/3x +4 --> y = mx+b form
the y intercept is 4 and the slope is -2/3, down 2, right 3.
therefore, the graph would contain a y intercept point of (0,4) and then from there u would start plotting down 2, going right 3 unit or up 2 and left 3 units. Then when u plotted at least 2/3/4 points, use a straightedge to draw the line.

Swedish researchers concluded that viewing and discussing art soothes the soul and helps relieve medical conditions such as high blood pressure and constipation. This conclusion was based on a study in which 20 elderly women gathered once a week to discuss different works of art. The study also included a control group of 20 elderly women who met once a week to discuss their hobbies and interests. At the end of 4 months, the art discussion group was found to have a more positive attitude, to have lower blood pressure, and to use fewer laxatives than the control group.
Required:
a. Why would it be important to determine if the researchers assigned the women participating in the study at random to one of the two groups?
b. Explain why you think that the researchers included a control group in this study.
Step-by-step explanation:
1. By assigning women at random. It would make these 2 groups comparable abc the result from the research or investigation would be more useful and valid. It is very important that there are two comparable groups.
2. A control group is useful in comparing both groups. It would help us to check if there's really an effect or if there is none. If all women were in in art group then all would likely make improvements and there would be no means of verifying this.

Which is one of the transformations applied to the graph of f(x) = x2 to produce the graph of p(x) = –50 + 14x – x2? a shift down 1 unit a shift left 7 units a shift right 1 unit a shift up 7 units
Answer:
Shift down one unit
Step-by-step explanation:
Correct for e2020
The transformation applied to the graph of f(x) to produce the graph of p(x) is:
A). a shift down 1 unit and a shift left 7 units.
What is transformation on the graphs?Let the functions f(x) and g(x) be two real functions.
And g (x) = f (x) + k, where k is real numbers.
The function can be sketched by shifting f (x), k units vertically.
The direction of shift can be found by the value of k:
if k > 0, the base graph shifts k units up, and
if k < 0, the base graph shifts k units down.
The function provided by the basic function f(x) and the constant
g(x) = f(x - k),
may be drawn by horizontally moving the f(x) k unit coordinates.
The shift's direction depends on the value of k. Specifically,
The base graph moves k units to the right if k > 0, and
The base graph moves k units to the left if k < 0.
To determine the transformation applied to the graph of f(x) = x² to produce the graph of p(x) = –50 + 14x – x², we can compare the general forms of the two functions:
f(x) = x²
p(x) = –x² + 14x - 50
The function p(x) can be written as,
p(x) = –(x² - 14x + 49) - 1
p(x) = -(x - 7)² - 1
Therefore, the transformation applied to the graph of f(x) to produce the graph of p(x) is:
A). a shift down 1 unit and a shift left 7 units.
So, the correct answer is A).

Barb’s Grandma is always creating math problems for her to solve. In one problem she gave Barb a store receipt that listed 72 identical items, each the same price, for a total cost of $*67.9* Barb’s grandma covered the first and last digits of the total price on the receipt with stars. Determine the value of the digits that Barb’s Grandma covered.
9514 1404 393
Answer:
367.92
Step-by-step explanation:
72 = 9·8
In order for the total cost to be divisible by both 8 and 9, it must meet a couple of requirements:
The sum of the digits must be divisible by 9. The last three digits must be divisible by 8.In order for the sum of digits to be divisible by 9, the first and last digits must total 5 or 14. (The total of existing digits is 22. The sum needs to be 27 or 36.)
In order for the last three digits to be divisible by 8, the last digit must be 2*. So, the first digit must be 5-2=3.
The first digit is 3; the last digit is 2.
The total cost is 367.92. Each item price is 367.92/72 = $5.11.

Find the equation of a line passing through the point (6,9) and (0,0)
Answer:
y=3/2x
Step-by-step explanation:
The equation of the required line as per slope-intercept form is 3x - 2y = 0.
What is the equation of a line passing through two points?The equation of a line that passes through points (x₁, y₁) and (x₂, y₂) is defined as:
m = (y₂ - y₁)/(x₂ - x₁)
Here, 'm' is the slope and 'c' is the y-intercept of the given line.
Therefore, the slope of a line that passes through (6, 9) and (0, 0) is
= (0 - 9)/(0 - 6)
= 3/2
Now, the general form of a line is y = mx + c. Here, 'm' is the slope and 'c' is the y-intercept of the line.
The line passes through the point (0, 0).
Therefore, 0 = (3/2) × 0 + c
⇒ c = 0
Now, the equation of the straight line is
y = (3/2)x + 0
⇒ 2y = 3x
⇒ 3x - 2y = 0

You have $150 in a savings account and you have some cash. The tape diagram represents the ratio of the amounts of money. You want to have twice the amount of money in your savings account as you have in cash. How much of your cash should you deposit into your savings account?
Answer: $200
Step-by-step explanation:
We know that:
You have $150 in a savings account.
This is represented with two tiles.
Then each tile represents:
$150/2 = $75
And in cash you have 5 tiles, then in cash you have:
5*$75 = $375.
Then the problem is:
You have $150 in the savings account
You have $375 in cash.
You want to deposit a quantity such that you have twice the amount of money in your savings account as you have in cash.
Suppose that you move a quantity X from cash to the savings account, then now we have the situation:
Sav. Acc. = $150 + X
Cash = $375 - X
And we want that:
Sav. Acc. = 2*Cash
($150 + X) = 2*($375 - X)
Let's solve this for X.
$150 + X = $750 - 2*X
3*X = $750 - $150 = $600
X = $600/3 = $200
You should deposit $200 in the Savings acount.
Tape diagrams are used to represent numbers as a ratio
$200 from the cash should be deposited into the savings account
Represent the amount in the savings account with s, and the cash with c.
So, we have the following ratio from the tape diagram
[tex]\mathbf{s : c = 2 : 5}[/tex]
You have $150 in the savings account.
So, the ratio becomes
[tex]\mathbf{150 : c = 2 : 5}[/tex]
Express as fractions
[tex]\mathbf{\frac c{150}= \frac 52}[/tex]
Multiply both sides by 150
[tex]\mathbf{c= \frac 52 \times 150}[/tex]
[tex]\mathbf{c= 375}[/tex]
Let the deposited amount be x.
Twice the amount in the savings account as cash means that:
[tex]\mathbf{150 + x = 2 \times (375 - x)}[/tex]
Open brackets
[tex]\mathbf{150 + x = 750 - 2x}[/tex]
Collect like terms
[tex]\mathbf{2x + x = 750 - 150}[/tex]
[tex]\mathbf{3x = 600}[/tex]
Divide both sides by 3
[tex]\mathbf{x = 200}[/tex]
Hence, $200 from the cash should be deposited into the savings account

(B) Graph F(x) for 0 < x s 15
(C) Find lim x--->10 F(x), lim x--->10F(x), and lim x--->10F(x), which- ever exist.
Answer and Step-by-step explanation:
Given:
Charges includes 10 hour per month = $50
Charges for additional hour = $9
Piecewise definition of cost F(x) for a month in which a member use a car for hours.
Find limits?
Find lim x--->10 F(x), lim x--->10F(x), and lim x--->10F(x), which- ever exist.
Lim x → 10- F(x) = 50$
Lim x → 10 [ 9x – 70] = 9( 10) – 70
= 90 – 70
= 20 > 10
Limit does not exist.
Lim x → 10+ F(x) = 50$
Lim x → 10+ F(x) = Lim x → 10+ [90x – 70]
= 90 – 70

The piece wise definition of the cost [tex]f(x)[/tex] for a month in which a member uses a car for [tex]x[/tex] hours is given by the equation,[tex]f(x)= 50+9(x-10)[/tex].
Given,
Membership plan is [tex]\$50[/tex] per month.
We have to write a piece wise definition of the cost [tex]f(x)[/tex] for a month in which a member uses a car for [tex]x[/tex] hours.
Here, [tex]\$[/tex][tex]$50[/tex] per month fees includes 10 hours of driving each month, so the cost for a month is given as,
[tex]f(x)= 50+9(x-10)[/tex]
Here [tex]x[/tex] is the no. of additional hours for the month.
Further,
[tex]f(x)= 9x-40[/tex].
Now at,
[tex]lim _{x \to 10^+}f(x) = 9\times 10-40\\[/tex]
Or,
[tex]f(x)= 90-40\\f(x)=50[/tex]
Similarly, at left limit,
[tex]lim _{x \to 10^-}f(x) = 9\times (-10)-40[/tex]
Or,
[tex]f(x)=-90-40[/tex]
[tex]f(x)=-130[/tex]
Finally at [tex]x=10[/tex], [tex]f(x)=9\times10-40[/tex]
[tex]f(x)=90-40\\f(x)=50[/tex]
Since [tex]lim{x \to}10^+[/tex] [tex]\neq limx\to 10^-\neq f(x) (at x= 10)[/tex]
So the required function [tex]f(x)[/tex] is discontinuous at [tex]x=10[/tex]
Hence the piece wise definition of the cost [tex]f(x)[/tex] for a month in which a member uses a car for [tex]x[/tex] hours is given by the equation,[tex]f(x)= 50+9(x-10)[/tex].
