A game room has a perimeter of 70 ft. The length is 5 more than twice the width. How many feet squared of new carpeting should be ordered?
Answers
Answer:
A = 250 square ft
Step-by-step explanation:
Equations
Let's call:
x = width of the game room
The length is 5 more than twice the width, thus:
2x+5 = length of the game room
The perimeter of a rectangle is twice the sum of the width and the length:
P = 2( x + 2x + 5 )
And the perimeter is 70 ft:
2( x + 2x + 5 ) = 70
Operating:
2( 3x + 5 ) = 70
Dividing by 2:
3x + 5 = 35
Subtracting 5:
3x = 30
Dividing by 3:
x = 30 / 3
x = 10
The width is 10 ft and the length is 2(10)+5=25 ft
The area of the game room is:
A = 10 ft * 25 ft
A = 250 square ft

What is area of circle?
The space a circle takes up in a two-dimensional plane is known as the area of the circle.Alternately, the area of the circle is the area included inside the circumference or perimeter of the circle. A = r², where r is the circle's radius, is the formula for calculating a circle's surface area. The square unit—for instance, m², cm², in², etc.—is the unit of area. In square units, the area of a circle is equal to r² or d²/4 where (Pi) = 22/7 or 3.14. The ratio of a circle's circumference to its diameter is known as pi (). This unique mathematical constant exists.Given :
Diameter of circle, d = 13cm

Farm sample:
Σx = 128.4
Σx² = 1617.94
n = 15
Sample mean, m = Σx / n ; 128.4 / 15 = 8.56
Standard deviation :
sqrt[(Σx²/n-1) - (m²)]
sqrt[(1617.94/14) - (8.56^2)]
sqrt(42.293542) = 6.50
Fourth spread = 3rd quartile - 1st quartile
3rd quartile = 3/4(n+1)th term
1st quartile = 1/4(n+1)th term
Using calculator :
Q3 = 11 ; Q1 = 4
Fourth spread = 11 - 4 = 7
Urban sample:
Σx = 246.0
Σx² = 11600
n = 11
Sample mean, m = Σx / n ; 246 / 11 = 22.36
Standard deviation :
sqrt[(Σx²/n-1) - (m²)]
sqrt[(11600/10) - (22.36²)]
sqrt(660.0304) = 25.69
Fourth spread = 3rd quartile (Q3) - 1st quartile(Q1)
3rd quartile = 3/4(n+1)th term
1st quartile = 1/4(n+1)th term
Q3 = 33 ; Q1 = 5
Fourth spread = 33 - 5 = 28
Standard deviation of farm sample = 6.50
Standard deviation of urban sample = 25.69
From the standard deviation values obtained, it could be observed that the urban sample has greater Variability than the farm sample, this is due to the higher standard deviation value of the urban sample and this shows that variation about the mean value is higher for urban sample.
Looking at the fourth spread value for both urban and farm samples ; the fourth spread value for urban is greater Than for farm sample.

Hi can you explain to me why we multiply by 4?
Answers
Okay, here we have this:
Considering the provided image, we are going check why we multiply by 4:
Since the system of equations was solved by elimination, then initially we must make that in both equations there is the same quantity of some of the variables with different sign, so that when adding them the variable is eliminated, then:
We see that in the first equation there is 2y, and that in the second there is 8y, so let's think for a moment about how much we must multiply 2y so that it gives 8y.
You got it right! We must multiply it by 4, but be careful, if you multiply on one side of the equation you must also multiply the other, the we have in the first equation:
\(2y=3x+8\)Now, let's multiply by 4:
\(4\cdot(2y)=(3x+8)\cdot4\)And by distributive law on the right side of the paranteisis we will multiply each term by 4, then we have:
\(4\cdot2y=(4\cdot3x)+(4\cdot8)\)And, that was the reason why it was multiplied by 4.

Bally Manufacturing sent Intel Corporation an invoice for machinery with a $13,100 list price. Bally dated the invoice August 01 with 3/10
EOM terms. Intel receives a 40% trade discount. Intel pays the invoice on August 14. On August 10, Intel Corporation returns $100 of the machinery due to defects. What does Intel pay Bally on August 14?
Answers
The Intel pays $7,760 to Bally Manufacturing on August 14.
The first step in calculating what Intel Corporation pays Bally on August 14 is to determine the net price of the machinery after the trade discount and the return of $100 due to defects.
The trade discount of 40% is calculated as follows:
Discount = List price × Discount rate
Discount = $13,100 × 0.40 = $5,240
So the net price of the machinery after the trade discount is:
Net price = List price - Discount
Net price = $13,100 - $5,240 = $7,860
After Intel returns $100 of machinery, the cost of the machinery is further reduced to:
Net price after return = Net price - Return
Net price after return = $7,860 - $100 = $7,760
Since the payment terms are 3/10 EOM (end of month), Intel receives a discount of 3% if payment is made within 10 days. The 10-day period begins on August 1 and ends on August 10 (the payment due date). Since Intel pays the bill on August 14, payment is late and the 3% discount does not apply.

The equation that could be used to represent this situation, where x is the course fee and R(x) is the total revenue, is: R(x) = 250000 + 375x - 2.5x²
What is an Equations?Equations are mathematical statements with two algebraic expressionsοn either sideοf an equals (=) sign. It illustrates the equality between the expressions writtenοn the left and right sides. To determine the valueοf a variable representing an unknown quantity, equations can be solved. A statement is not an equation if there is no "equal to" symbol in it. It will be regarded as an expression.
N(x) = 625 + 2.5x
The revenue R(x) will be the productοf the numberοf students enrolled and the fee charged per student. The fee charged per student will be (400 - x) dollars. So, the revenue function can be represented as:
R(x) = (625 + 2.5x)(400 - x)
Simplifying the expression, we get:
R(x) = 250000 + 375x - 2.5x²
Therefore, the equation that could be used to represent this situation, where x is the course fee and R(x) is the total revenue, is:
R(x) = 250000 + 375x - 2.5x²

Let g(x) be the Fourier series for the periodic extension of f(x) = -2 if x=03x + 2 if 0 < x <3 11 if 3
Answers
The Fourier series for the periodic extension of F(x) is given by: G(x) = 8 + Σ[(9/(jnpi)) * [(-1)^n - 1] - (2/(jnpi)) * [e^(-jnpi/4) - 1] + (11/(jnpi)) * [1 - e^(-jnpi/2)]] * e^(jnpi*x/4) from n = 1 to ∞
What is the Fourier series for the periodic extensionTo find the Fourier series for the periodic extension of F(x), we need to find the Fourier coefficients.
The period of the function is T = 8, so the fundamental frequency is w0 = 2*pi/T = pi/4.
The Fourier coefficients are given by:
cn = (1/T) * integral from -T/2 to T/2 of [f(x)*e^(-jnw0x) dx]
where n is an integer.
For n = 0, we have:
c0 = (1/T) * integral from -T/2 to T/2 of [f(x) dx]
= (1/8) * [integral from 0 to 3 of (3x+2) dx + integral from 3 to 8 of 11 dx - 2*integral from 0 to 3 of dx]
= (1/8) * [28 + 40 - 6]
= 8
For n ≠ 0, we have:
cn = (1/T) * integral from -T/2 to T/2 of [f(x)*e^(-jnw0x) dx]
= (1/8) * [integral from 0 to 3 of (3x+2)e^(-jnw0x) dx + integral from 3 to 8 of 11e^(-jnw0x) dx]
For the first integral, we have:
integral from 0 to 3 of (3x+2)e^(-jnw0x) dx
= (3/(-jnw0)) * [e^(-jnw0x)(3x+2) |_0^3] - (2/(-jnw0)) * integral from 0 to 3 of e^(-jnw0x) dx
= (9/(jnpi)) * [(-1)^n - 1] - (2/(jnpi)) * [e^(-jn*pi/4) - 1]
For the second integral, we have:
integral from 3 to 8 of 11e^(-jnw0x) dx
= (11/(-jnw0)) * [e^(-jnw0x) |_3^8]
= (11/(jnpi)) * [e^(-2jnpi) - e^(-3jnpi/2)]
= (11/(jnpi)) * [1 - e^(-jnpi/2)]
Therefore, we have:
cn = (1/8) * [(9/(jnpi)) * [(-1)^n - 1] - (2/(jnpi)) * [e^(-jnpi/4) - 1] + (11/(jnpi)) * [1 - e^(-jn*pi/2)]]
The Fourier series for the periodic extension of F(x) is given by:
G(x) = Σcn * e^(jnw0x) from n = -∞ to ∞
Substituting the values of c0 and cn, we have:
G(x) = 8 + Σ[(9/(jnpi)) * [(-1)^n - 1] - (2/(jnpi)) * [e^(-jnpi/4) - 1] + (11/(jnpi)) * [1 - e^(-jnpi/2)]] * e^(jnpi*x/4) from n = 1 to ∞

a) How many fewer euros did he receive due to this delay? |20
b) What percentage loss was caused by this delay?
Answers
The amount of fewer euros he would receive as a result of the delay is 20 E.
The percentage loss that was caused by the delay is -4%.
What is the fewer euros received and the percentage loss?
Exchange rate is the rate at which one unit of a currency can buy another currency. In this question, the value of Euros appreciated by Monday. This is because $1 buys less Euros on Mondays. On the hand, dollars depreciates in value.
Amount of fewer Euros received = value of euros if it were exchanged on Friday - value of euros if it was exchanged on Monday
Value of euros if it were exchanged on Friday = 1.25 x 400 = 500 E
Value of euros if it was exchanged on Monday = 1.20 x 400 = 480 E
Difference = 500 E - 480 E = 20 E
Percentage loss = (Euros received on Monday / Euros that would have been received on Friday) - 1
Percentage loss = (480 / 500) - 1 = -0.04 = -4%
