General Motors stock fell from 32$ per share in 2006 to 20$ per share during 2008. A) If you bought and then sold 300 shares all these prices what was your loss B) Exress your loss as a percent of the purchase price
Answer:
Step-by-step explanation:
total purchase price = 32*300 = 9600
total selling price = 20*300 = 6000
Net capital loss =total purchase price- total selling price =9600-6000 = 3600. Purchase price of one share is 32
Selling price of one share is 20
Number of shares bought are 300 Net % loss = (3600*100)/9600=37.5%
Final answer:
The total loss from buying and then selling 300 shares of General Motors stock, which fell from $32 to $20 per share, is $3600. Expressed as a percent of the purchase price, the loss is 37.5%.
Explanation:
To calculate the loss when buying and selling shares, we first find the loss per share and then multiply by the total number of shares. For General Motors, the price fell from $32 per share to $20 per share. This results in a loss of $12 per share. If you bought and sold 300 shares at these prices, your total loss would be:
Loss per share = $32 - $20 = $12
Total loss = $12 × 300 shares = $3600.
To express this loss as a percent of the purchase price:
Loss Percentage = (Loss per share / Purchase price per share) × 100
Loss Percentage = ($12 / $32) × 100 = 37.5%.

A restaurant bill comes to $28.35 find the total coast if the tax is 6.25% and 20% tip is left on the amount before tax
Answer:
The total cost of the bill = $36.146
Step-by-step explanation:
Here, the total amount of the bill = $28.35
Now, the amount of tip = 20%
So, calculating 20% on the bill amount, we get
[tex]\frac{20}{100} \times 28.35 = 5.67[/tex]
or, the amount of 20% tip = $5.67
So, the total bill amount after 20% tip = Bill Amount + Tip
= $28.35 + $5.67 = $34.02
Now, the tax is calculated on the amount of bill $34.02.
[tex]\frac{6.25}{100} \times 34.02 = 2.126[/tex]
or, the amount of tax on the bill = $2.126
So, the total bill amount after 6.25% tax = Bill Amount + Tax
= $34.02 + $2.126 = $36.146
Hence, the total cost of the bill = $36.146.

(A) $68 Khles Hot money = 3
(B) $136
(C) $204
(D) $306
(E) $408
The right answer is Option D.
Step-by-step explanation:
Let,
Kyle's money = x
Hayden's money = y
Jeremy's money = z
According to statements;
Kyle has three times as much money in his savings account as Hayden.
x = 3y Eqn 1
Hayden has twice as much money in his savings account as Jeremy.
z = 2y Eqn 2
Combined Kyle, Hayden, and Jeremy have a total of $612.
x+y+z=612 Eqn 3
Putting value of x and z from Eqn 1 and 2 in Eqn 3
[tex]3y+y+2y=612\\6y=612[/tex]
Dividing both sides by 6
[tex]\frac{6y}{6}=\frac{612}{6}\\y=102[/tex]
Putting in Eqn 1;
[tex]x=3(102)\\x=306[/tex]
Kyle has $306 in his account.
The right answer is Option D.

A rectangle has 3 square feet and width 1/2 foot. What is the length of the rectangle
Answer:
We Know, Area = Length * Width
Here, A = 3
W = 1/2
Substitute it into the expression,
3 = L * 1/2
L = 3/ 1/2
L = 3/2 ft²
So, the length of the rectangle would be 3/2 ft²
Hope this helps! :)
The length of the rectangle is found to be 6 feet by using the formula for the area of a rectangle and solving for length.
Explanation:To compute the length of the rectangle, we need to use the formula for the area of a rectangle which is length times width. Given that the area is 3 square feet and the width is 1/2 foot, we can set up the equation length * 1/2 = 3 square feet. From here, solve for length by dividing both sides of the equation by 1/2.
Therefore, the length of the rectangle is 6 feet.

Answer:

Step-by-step explanation:
To find the angle inside the triangle (to the right side of 90 degree angle), we first have to find the adjacent angle (below it).
Angle 122 and that adjacent angle is same (parallel lines cut by transversal -- they are corresponding angles).
So that angle is 122.
The inside triangle angle (what we want) is adjacent to 122, so we can write:
Angle + 122 = 180 [straight angle/straight line is 180 degrees]
Solving for that angle, we have:
Angle = 180 - 122 = 58
Now, looking at the triangle, Side C is "opposite" of 58° and side "20" is the side that is "hypotenuse" [side opposite of 90 degree angle is hypotenuse).
Which trig ratio relates "opposite" and "hypotenuse"??
Yes, it is SIN. Thus we can write:
[tex]Sin(58)=\frac{Opposite}{Hypotenuse}=\frac{C}{20}[/tex]
We can now solve for C:
[tex]Sin(58)=\frac{C}{20}\\C=20*Sin(58)\\C=16.96[/tex]

What is y - 2 = -3(x – 7) written in standard form?
Choose 1 answer:
A-y - 2 = -3x + 21
B-y=-3x + 23
C-3x + y - 23 = 0
D-3x + y = 23
Answer:
It's D
Step-by-step explanation:
-3+y=23
To write the equation in standard form, distribute and rearrange the terms. The equation is 3x + y = 23.
Explanation:To write the equation y - 2 = -3(x - 7) in standard form, we need to expand the expression and rearrange the terms. Starting with the given equation, we can distribute the -3 to the terms inside the parentheses: y - 2 = -3x + 21. Next, we can move the -3x term to the left side of the equation by adding 3x to both sides: 3x + y - 2 = 21. Finally, we can move the constant term (-2) to the right side of the equation by adding 2 to both sides: 3x + y = 23. Therefore, the equation in standard form is 3x + y = 23 (Option D).

A freight train travels 1445 miles in 25 hours. What is the train's average rate of speed?
Final answer:
The average speed of the freight train is found by dividing the distance traveled, 1445 miles, by the time taken, 25 hours, resulting in an average speed of 57.8 mph.
Explanation:
To calculate the average speed of the freight train, we divide the total distance traveled by the time it took to cover that distance. The train travels 1445 miles in 25 hours.
The formula for average speed is:
average speed = total distance / total time
Therefore, the average speed of the train is:
average speed = 1445 miles / 25 hours = 57.8 miles per hour (mph)

Step-by-step explanation:
Are all right triangles similar?Are all equilateral triangles similar?
Answer:
Yes to both.
Step-by-step explanation:
Similar means the same shape but the sizes may be different.
Right angles are similar and so are equilateral triangle.
Right triangles are not necessarily similar unless they have the same hypotenuse and an acute angle. All equilateral triangles are similar because they have equal angles and sides. This discussion relates to the nature of mathematical truths, which are absolute in their systems, compared to observational truths that rely on variable sensory evidence.
Not all right triangles are similar because they can have different ratios between their sides despite having a right angle. However, if two right triangles have the same length of their hypotenuse and an acute angle correspondingly, they are indeed similar according to a mathematical corollary.
In contrast, all equilateral triangles are similar because they all have equal angles (60 degrees each) and their side lengths are also in the same ratio, which is 1:1:1, making them the same shape, although they can be different sizes.
This connects to the larger questions about mathematical truths. For instance, the statement that the three interior angles of a triangle are equivalent to two right angles is a mathematical truth that is similar to definitional truths, such as 'green is a color,' since both are based on definitions and logical deductions in their respective systems.
However, mathematical truths differ from observational truths like 'there is beer in the refrigerator' because observational truths are subject to sensory evidence which can change, whereas mathematical truths are absolute within the context of their axiomatic systems.
When considering questions that lead to insights into forms, mathematical questions are often better suited over observational ones as they transcend physical reality and provoke a more abstract level of reasoning.
