The sale price of the 2nd Washing machine is more expensive and profitable than the first Washing machine, So Kareem should choose the 2nd Washing machine to get profit.
Selling price and Marked price:The price a buyer pays for a good or service is known as the selling price. When the selling price is greater than the cost price, then we will get a Profit. Marked price, is the amount that a seller actually receives from a customer after negotiating a price or striking a deal.
Here we have
The selling price of washing machines is $520
The first one is marked down by 40%.
The second is marked down by 10% with an additional 30% off.
For the first Washing machine,
Let x be the sale price of the machine
Given that the price is 40% marked down
=> the selling price of Washing machine = x - 40% of x
= [tex]x - \frac{40x}{100}[/tex]
= x - 0.4x = 0.8x
As we know the selling price of the washing machine = $ 520
=> 0.8x = 520
=> x = 520/0.8
=> x = 650
The sale price of the first washing machine = $ 650.
For the 2nd Washing machine,
Let y be the sale price of the machine
Given that the price is 10% marked down
=> the selling price of Washing machine = y - 10% of y
= [tex]y - \frac{10y}{100}[/tex]
= x - 0.1x = 0.9x
And given 30% off
30% off on 0.9x = 30% of 0.9x
The selling price will be = 0.9x - 30% of 0.9x
=> 0.9x - 0.27x = 0.63x
As we know the selling price of a washing machine = $ 520
=> 0.63x = 520
=> x = 520/0.63
=> x = 825.39
The sale price of the 2nd washing machine = $ 825.39.
By the above calculations
The sale price of the 2nd Washing machine is more expensive and profitable than the first Washing machine, So Kareem should choose the 2nd Washing machine to get profit.

What are the many sorts of cost?
Fixed and variable costs are the two main categories of expenses incurred by enterprises. While variable costs fluctuate with output, fixed costs do not.
Sometimes, fixed costs are referred to as overhead costs. They must be paid whether a company produces 100 or 1,000 widgets.
The cost function is given by
C(x ) = 15x + 1000
It is also given that it costs $25 per ride.
so,
Revenue function for x number of rides be
R(x) = 20x
For break even:-
The cost must be equal to the Revenue i.,e
C(x) = R(x)
15x + 1000 = 20x
1000 = 20x - 15x
1000 = 5x
x = 1000/5
x = 200
Therefore, 200 rides does it take to break even.

The value of x is 1.
The value of y is 4.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 - 9 = 5 is an equation.
We have,
-4.5x - 2y = -12.5 ____(1)
3.25x - y = -0.75 _____(2)
From (1) we get,
-4.5x + 12.5 = 2y
y = (-4.5x + 12.5) / 2 _____(3)
Now,
3.25x - y = -0.75
Putting (3) in (2) we get,
3.25x - (-4.5x + 12.5) / 2 = -0.75
6.5x + 4.5x - 12.5 = 2 x -0.75
11x - 12.5 = -1.5
11x = -1.5 + 12.5
11x = 11
x = 1
Now,
From (3) we get,
y = (-4.5x + 12.5) / 2
y = (-4.5 x 1 + 12.5) / 2
y = (-4.5 + 12.5) / 2
y = 8/2
y = 4

A publisher needs to send many books to a local book retailer and will send the books in a combination of small and large boxes. Each small box can hold 20 books and each large box can hold 45 books. There were twice as many large boxes sent as small boxes, which altogether can hold 440 books. Write a system of equations that could be used to determine the number of small boxes sent and the number of large boxes sent. Define the variables that you use to write the system.
In linear equation, 20x + 45y = 440 , y = 2x Where x is the number of small boxes sent and y is the number of large boxes sent.
What in mathematics is a linear equation?

Suppose UV=17, BV=18, SAU=92, and TBV=24
The required angles ∠TBS and ∠TCV are 48° and 22° respectively.
What is right angled triangle ?A right-angled triangle is a kind of triangle that has one of its points equivalent to 90 degrees. The other two points summarize to 90 degrees. The sides that incorporate the right point are opposite and the foundation of the triangle. The third side is known as the hypotenuse, which is the longest side of each of the three sides
According to question:∠TBV = 24°
∠VBS = 24°
So, ∠TBS = (24° ) = 48°
And,
∠SAU = 92°,
So,
∠VAU = 46°
In ΔTAC
∠TAC + ∠TCA = 90°

What is a angle bisector?
In geometry, an angle bisector is a line that divides an angle into two equal angles. The term "bisector" refers to a device that divides an object or a shape into two equal halves. An angle bisector is a ray that divides an angle into two identical segments of the same length.
As given in question:
AV , BV and CV are the angle bisector of ΔABC
UV = 17, BV = 18
∠SAU =92° and ∠TBV = 24°
Now,
∠TBV = ∠SBV = 24° ( BV is angle bisector)
So, ∠TBS = ∠TBV + ∠SBV
∠TBS = 24° + 24° = 48°
SV = UV = 17 (V is the incenter of ΔABC.)
∠SAU + ∠TBS + ∠TCU = 180° (Sum of angles of a triangle)
92° + 48° + ∠TCU = 180°
∠TCU = 180° - 140°
∠TCU = 40°
So, [tex]\angle TCV = \frac{40\degree}{2}[/tex]
∠TCV = 20°
∴ ∠TBS = 48°
SV = 17

Paige can sort her toys in 6 fewer hours that Madison can. When they work together, it
takes them only 4 hours to sort the toys. How long would it take for each of them to sort
the toys alone?
Let X be the number of hours it takes Paige to sort the toys alone.
It takes Madison X + 6 hours to sort the toys alone.
Together, it takes them X + (X + 6) = 4 hours to sort the toys.
Combining like terms, we get 2X = 4
Dividing both sides by 2, we get X = 2
Therefore, it takes Paige 2 hours to sort the toys alone.
It takes Madison 2 + 6 = 8 hours to sort the toys alone.

The 3rd term in a geometric sequence is -18 and the 6th term is 9216.
Find the a) common ratio, b) the first term a1, and c) the 4th term a4 in this geometric sequence.
Answer: The common ratio of the geometric sequence is 1/2, the first term is -72, and the 4th term is -9.
Step-by-step explanation: The common ratio r of a geometric sequence is found by dividing the second term by the first term, and the nth term of the geometric sequence is given by a1 * r^(n-1), where a1 is the first term.
To find the common ratio r of this geometric sequence, we can use the fact that the 3rd term is -18 and the 6th term is 9216:
-18 = a1 * r^2
9216 = a1 * r^5
Dividing these two equations, we get:
-18/9216 = (a1 * r^2) / (a1 * r^5)
-18/9216 = r^-3
r = (-18/9216)^(-1/3)
Since r is the common ratio, it must be positive. Since (-18/9216)^(-1/3) is negative, we must take the positive root:
r = ((-18/9216)^(-1/3))^(1/3)
r = ((-18/9216)^(1/9))
r = (9216/-18)^(1/9)
r = (-512)^(1/9)
r = (-8)^(1/9)
r = (-2)^(2/9)
r = (-2)^(2/3)
r = (1/4)^(2/3)
r = 1/2
To find the first term a1, we can use the fact that the 3rd term is -18 and the common ratio is 1/2:
-18 = a1 * (1/2)^2
-18 = a1/4
a1 = -72
To find the 4th term a4, we can use the fact that the first term is -72 and the common ratio is 1/2:
a4 = (-72) * (1/2)^3
a4 = -9
Therefore, the common ratio of the geometric sequence is 1/2, the first term is -72, and the 4th term is -9.
A total of 420 tickets were sold for the school play they were either adult tickets or student tickets the number of student tickets sold was three times the number of adult tickets sold how many adult tickets were sold
Answer: I believe 140
Step-by-step explanation: This is how I found my answer:
420 / 3
= 140
420-140
= 280
420= number of all tickets sold.
140= number of adult tickets sold
280= number of student tickets sold
You might wonder how I know why it's 140. I know it's 140, because using my context clues, it stated:
"the number of student tickets sold was three times the number of adult tickets."
So, the one that was the bigger amount must be the student's tickets sold, while the lower amount has to be the adult's tickets sold. I hope this helped!

The 1 dollars found near the table by your friend is likely the money for the tickets.
How to find if the money belong to the ticket money?You are selling tickets at a dance. Individual tickets cost $6, and 2 tickets for a couple cost $10. After the dance, you count $1075 and 195 tickets.
let
x = number of individual ticket
y = number of couple tickets = 2x
Therefore, using equation,
2x(10) + 6x = 1075
2x + x = 195
Hence,
20x + 6x = 1075
3x = 195
x = 195 / 3
x = 65
Hence,
26x = 1075
26(65) = 1690
Therefore, the money on the table is the ticket money because the money is short of the amount of the tickets in dollars.
