Jimmy earns $500 a week selling shoes. He also earns 8% commission on all of his shoe sales. Last week, he sold $1,540 worth shoes. How much money did Jimmy earn last week?
show work
To determine the amount Jimmy made last week, you will need to calculate the commission he made on his sales and add the $500 to that amount.
Here is the math equation showing this:
($1540 x 0.08) + $500 = $623.20
Jimmy made $623.20 last week.

Answer:
the slope is 2.5
(from x=0 to x=2 it goes up by 5)
-2 is the intercept with the y-Axis
the general formula is:
y = m*x + b
where m is the slope and b the intercept
here you go:
y = 2.5x -2

A laptop has a listed price of $891.99 before tax. If the sales tax rate is 9.25%, find the total cost of the laptop with sales tax included.
Round your answer to the nearest cent, as necessary.
Please explain to me.
Answer:
$974.50
Step-by-step explanation:
The sales tax is 0.0925($891.99), or $82.51. We need only add this amount to the listed price ($891.99) to find the total cost with sales tax included:
$891.99
+ 82.51
--------------
$974.50
An alternative approach would be to multiply the listed price by 1.0925:
1.0925($891.99) = $974.50
Here the '1' refers to the listed price and the '0.0925' to the sales tax.
find the other x-intercept for the parabola defined by this equation y=2x2+3-2
Answer:
( [tex]\frac{1}{2}[/tex], 0 )
Step-by-step explanation:
To find the x- intercepts let y = 0, that is
2x² + 3x - 2 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 2 = - 4 and sum = + 3
The factors are + 4 and - 1
Use these factors to split the x- term
2x² + 4x - x - 2 = 0 ( factor the first/second and third/fourth terms )
2x(x + 2) - 1 (x + 2) ← factor out (x + 2) from each term
(x + 2)(2x - 1) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]
The x- intercepts are (- 2, 0 ), ( [tex]\frac{1}{2}[/tex], 0 )
4x-3=2x+7
2x+6=7x-14

Answer:
1/8
Step-by-step explanation:
( 2^-1 / 2^0) ^3
First simplify inside the parentheses
We know that a^b / a^c = a^(b-c)
2^(-1-0) = 2^-1
( 2^-1 ) ^3
Then we know that a power to a power is
a^b^c = a^(b*c)
2^(-1 *3)
2^ -3
Then a negative exponent makes it a fraction
a^ -b = 1/a^b
1 /2^3

Can someone help me with this question?
Answer:
A = 20.25 sq units
Step-by-step explanation:
to find the area of a square you only need to know the measure of one side -- all other sides will be equal to it
it appears the segment is 4.5 units so you would square that to get the area
A = 4.5²
A = 20.25

graph the image of triangle abc after dilation with the scale factor of 3 centered at the origin?
Answer:
A' = (0,0)
B' = (6,-12)
C' = (-12,-12)
Step-by-step explanation:
According to the Question,
Let's label the corner points of the triangle A,B,C starting at the origin and moving clockwise(ForDiagram Please Find in Attachment)A = (0,0) , B = (2,-4) , C = (-4,-4)
Dilating with a scale factor 3 means we multiply each coordinate of each point by the value 3A = (0,0) becomes A' = (0,0). No change happens. This point is fixed
B = (2,-4) becomes B' = (6,-12). This point does move
C = (-4,-4) becomes C' = (-12,-12). This moves as well
So all you need to do from here is draw triangle A'B'C'.
Note ⇒
the lengths of triangle A'B'C' are Thrice as long as their counterparts on triangle ABC. Consequently, this means the perimeter of A'B'C' is Thrice as long as the perimeter of ABC. Also, triangle A'B'C's area is Nine times larger than the area of triangle ABC.Please I have been waiting for an answer. somebody help me I give brainlist

What is the area❓ No links or troll answers you’ll be reported
Answer:
103
Step-by-step explanation:
Find the area of the rectangle on the top
A = 7*13 = 91
Now find the area of the rectangle on the bottom
13 - (5+5) = 3
11-7 = 4
The dimensions of the bottom rectangle are 3 by 4
A = 3*4 = 12
The total area is 91+12 = 103

What is the slope of the line that passes through the points (26, 7) and (-39, 12)?
Answer:
-1/13
Step-by-step explanation:
The slope of a line is calculated as rise/run.
The rise is the difference in y-values, and the run is the difference in x values
slope= y₂ - y₁/x₂ - x₁
let (26 , 7) be (x , y) and (-39 , 12) be (x₂, y₂)
slope= (12 - 7)/ (-39 -26)
= 5/-65
reduce the fraction to get -1/13

d the volume of the entire figure by adding the volumes of the separate
Answer:
Total Volume = 190 m³
Step-by-step explanation:
Volume of the entire figure = L (Area 1 + Area 2)
where L = 10 m
Area 1 (blue prism) = 4 x 3 = 12 m²
Area 2 (brown prism = 1 x 7 = 7 m²
plugin values into the formula:
Volume of the entire figure = L (Area 1 + Area 2)
= 10 (12 + 7)
= 120 m³ + 70 m³
= 190 m³
When the dragons have lost their most recent game, fans buy 200 tickets. For each consecutive win the dragons have, the number of tickets fans buy increases by a factor of 1.1 Which expression gives then number of tickets fans buy after 4 consecutive wins?
Answer:
Y(4) = 200(1.1)^4
Step-by-step explanation:
Given that :
Number of tickets purchased before consecutive wins = 200
For each consecutive win, ticket purchased increases by a factor of 1.1
Number of tickets after 4 wins
This scenario describes an exponential relation :
Where increase is factor based and not a certain number :
Hence,
Number of tickets, Y= Initial number of ticket * growth factor^number of wins
Hence, we have
Y(n) = 200(1.1)^n
Y(4) = 200(1.1)^4 = 292.82
Consider the quadratic equation 2x² + 72 + k = 0. Which value of k results in the equation having complex solutions?
Hi there!
[tex]\large\boxed{k> 6.125}[/tex]
We can use discriminants to determine the value of k for which the equation would have complex solutions. (Those involving i)
If b² - 4ac < 0, then the equation will have complex solutions. Therefore:
Plug in the given values of b and a to solve:
7² - 4(2)(k) < 0
Simplify:
49 - 8k < 0
Solve the inequality:
49 < 8k
6.125 < k
k > 6.125. Anything greater than 6.125 would result in complex solutions.

Answer: [tex]2\sqrt{2}[/tex]
=====================================
Explanation:
Let's say we replace every copy of [tex]\sqrt{2}[/tex] with x
Doing so means we have the expression 5x-3x. That simplifies to 2x.
The last thing to do is replace the x with [tex]\sqrt{2}[/tex] and that's how we end up with [tex]2\sqrt{2}[/tex] as the final answer.
----------
In short: we subtract the numbers out front, and then tack on a root 2 at the end.
As another example, [tex]19\sqrt{2}-11\sqrt{2} = (19-11)\sqrt{2} = 8\sqrt{2}[/tex]
This is basically the same as saying 19x-11x = (19-11)x = 8x where [tex]x = \sqrt{2}[/tex]
