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.

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.
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%.
Find the sum of the first 50 terms in this geometric series 1+10/11+100/121
Answer:
10.91
Step-by-step explanation:
The sum of the first 50 terms in this geometric series is 11.00.
What is a geometric series?When all the terms of a geometric sequence are added, then that expression is called geometric series.
Lets suppose its initial term is f=a , multiplication factor is r
and let it has total n terms, then, its sum is given as:
[tex]S_n = \dfrac{a(r^n-1)}{r-1}[/tex]
(sum till nth term)
We are given that;
n=50
Series= 1+10/11+100/121
Now,
To find the sum of the first 50 terms in this geometric series, we need to use the formula:
Sum = [tex]a1(1 - r^n) / (1 - r)[/tex]
where a1 is the first term, r is the common ratio, and n is the number of terms. We can identify that the first term is 1, the common ratio is 10/11, and the number of terms is 50. Plugging these values into the formula, we get:
Sum = 1(1 - (10/11)^50) / (1 - 10/11) Sum = (1 - 0.000000000000000000000000000000000000000000000001) / (1/11) Sum = (0.9999999999999999999999) / (0.09090909) Sum = 10.99998
Rounding this result to two decimal places, we get:
Sum = 11.00
Therefore, by the given geometric sequence the answer will be 11.00.

Goldberg's sleigh currently runs at 203mph, but he needs it to reach 400mph with all the packages he has to deliver.
If Goldberg is delivering presents at an altitude of 5,813.6ft, with the same drag and weight of a 2019 Challenger SRT® Hellcat Redeye, how much HP would he need to reach 400 mph?
Pro Tips:
100% driveline efficiency
P (air density) at 5813.6 ft = .0019 slug/ft^3
A (Area of Challenger front end) = 26.72 ft^2
C(d) (Coefficient of drag) = .398
Goldberg's sleigh required speed, 400 MPH = 587 ft/sec
F(drag) = 1/2 p x v^2 x C(d)A
P = F(drag) x V
Convert to Horsepower = P ( 1HP/550 ft lbf/sec)
Answer:
5,813 HP
Step-by-step explanation:
P=f*v
f=1/2*p*v^2*C*A
HP=(f*v)/550
Answer:
He needed 3747.61 HP to reach 400 mph.
Step-by-step explanation:
Given data :
P (air density) = 0.0019 slug/ft³
A (Area) = 26.72 ft²
C(d) = 0.398
crr = 0.015
V = 400 mph = 587 ft/sec = 178.92 m/sec
weight = 2019 lb = 8980.96 N [1 pound = 4.44822 N]
[tex]P=\frac{Force\times Displacement}{Time}[/tex]
P = Force × Velocity = FV
F = F(sum) = F(drag) + F(rolling resistance)
F(drag) = [tex]\frac{1}{2}P\times V^2\times C(d)A[/tex]
F(rolling resistance) = weight × crr
[tex]HP=\frac{P}{1hp}[/tex] 1hp = 745.7 watts
F(drag) = [tex]\frac{1}{2}P\times V^2\times C(d)A[/tex]
[tex]=\frac{1}{2}\times 0.0019\times 587^{2} \times 0.398\times 26.72[/tex]
= 3481.23 [tex]\frac{slug\times ft}{sec^2}[/tex]
convert [tex]\frac{slug\times ft}{sec^2}[/tex] to [tex]\frac{kg\times m}{s^2}[/tex]
1 slug = 14.5939 kg
1 ft = 0.3048 m
[tex]\frac{slug\times ft}{sec^2}[/tex] = 14.5939 × 0.3048 = 4.448 [tex]\frac{kg\times m}{s^2}[/tex] or newton
Since F(drag) = 3481.23 × 4.448 N
= 15484.51 N
P = F(drag) × V
= 15484.51 × 178.92 N m/s
= 2770488.529 watts
F rolling resistance = crr × w
= 0.015 × 8980.96 N
= 134.714 N
Power = (Fdrag + Frolling resistance) × V
= (15484.51 + 134.714) × 178.92
= 15619.224 × 178.92
= 279459.558 watts
Power in HP
[tex]HP=\frac{P}{hp}[/tex]
[tex]=\frac{279459.558}{745.7}[/tex]

this year a softball coach raised $1200 for new equipment. that is 4 percent less then last year. how much did he raise last year?
Answer:
The coach raised $1250 last year
Step-by-step explanation:
Let the amount raised last year be $x
Amount raised this year = $1200
Amount raised this year was less by the 4% of x amount last year:
1200 = x - 4% of x
1200 = x - x (x) 4/100 = 96x/100
x = $1250
The coach raised $1250 last year for the equipment.

Multiplying Eqn 1 by 3;
[tex]3(14x+5y=12)\\42x+15y=36\ \ \ Eqn \ 3[/tex]
Subtracting Eqn 2 from Eqn 3;
[tex](42x+15y)-(10x+15y)=36-24.80\\42x+15y-10x-15y=11.20\\32x=11.20\\[/tex]
Dividing both sides by 32
[tex]\frac{32x}{32}=\frac{11.20}{32}\\x=0.35[/tex]
Putting x=0.35 in Eqn 1;
[tex]14(0.35)+5y=12\\4.90+5y=12\\5y=12-4.90\\5y=7.10[/tex]
Dividing both sides by 5
[tex]\frac{5y}{5}=\frac{7.10}{5}\\y=1.42[/tex]
Therefore, one large envelope costs $1.42

Of the total number of spectators at a circus show, 1/4 are men. 2/5 of the remaining number of spectators are women. There are 132 women at the circus show. How many children are at the circus show?
Answer: There are [tex]198[/tex] children at the circus show.
Step-by-step explanation:
Let be "x" the total number of spectators at the circus show and "c" the number of children at the circus show.
Knowing that [tex]\frac{1}{4}[/tex] of the spectators are men, we can find the remaining:
[tex]x-\frac{1}{4}x=\frac{3}{4}x[/tex]
Since [tex]\frac{2}{5}[/tex] of the remaining number of spectaros are women and there are a total of 132 women, we can write the following equation:
[tex](\frac{2}{5})(\frac{3}{4}x)=132[/tex]
Solving for "x", we get:
[tex]x=(132)(\frac{20}{6})\\\\x=440[/tex]
Therefore, we get that "c" is:
[tex]c=440-\frac{1}{4}(440)-132\\\\c=198[/tex]

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 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.
