Cindy is designing a rectangular fountain in the middle of a courtyard. The rest of the courtyard will be covered in stone.The part of the courtyard that will be covered in stone has an area of 246 square feet. What fraction of the area of the courtyard will be occupied by the fouantain.

Answers

Answer 1

The fountain will occupy a fraction of 50/173 of the Total area of the courtyard.

Let A be the area of the courtyard and F be the area of the fountain.

We know that the area of the stone-covered part of the courtyard is 246 square feet.

So, the area of the whole courtyard is A = 246 + F square feet.

The fraction of the area of the courtyard occupied by the fountain is given by:

F / A = F / (246 + F)

We can simplify this expression by multiplying the numerator and denominator by the reciprocal of the denominator:

F / A = F / (246 + F) * (1 / (246 + F))

F / A = F / (246 * (246 + F))

F / A = 1 / (246 / F + 1)

We don't know F yet, but we can use the fact that the fountain is rectangular to set up an equation relating the length and width of the fountain:

F = L * W

where L is the length of the fountain and W is the width of the fountain.

We also know that the perimeter of the fountain is 50 feet:

2L + 2W = 50

Simplifying this equation, we get:

L + W = 25

Solving for one variable in terms of the other, we get:

L = 25 - W

Substituting this expression for L into the equation for F, we get:

F = (25 - W) * W

Expanding this expression, we get:

F = 25W - W^2

We also know that the cost of the fountain is $600, which includes installation. So, we can set up another equation relating the cost of the fountain to its dimensions:

1.5LW = 600

Substituting 25 - W for L, we get:

1.5(25 - W)W = 600

Expanding and simplifying this equation, we get:

W^2 - 25W + 400 = 0

Solving this quadratic equation, we get:

W = 20 or W = 5

We reject the solution W = 5 because it implies a negative length for the fountain, which is not physically possible. Therefore, the width of the fountain is W = 20 feet and its length is L = 25 - W = 5 feet.

The area of the fountain is therefore:

F = L * W = 5 * 20 = 100 square feet

The fraction of the area of the courtyard occupied by the fountain is

F / A = 100 / (246 + 100) = 100 / 346 = 50 / 173

So, the fountain will occupy a fraction of 50/173 of the total area of the courtyard.

x is an acute angle. Find the value of x in degrees. sin(x)=0.1 Write your answer as an integer or as a decimal rounded to the nearest hundredth. x=

Answers

X is an acute angle x = 5.74 degrees (rounded to the nearest hundredth) would be the appropriate answer for an acute angle satisfying sin(x) = 0.1.

To find the value of x in degrees when sin(x) = 0.1, we can use inverse trigonometric functions. Specifically, we can use the arcsin function to determine the angle whose sine is 0.1.

Using a scientific calculator or a trigonometric table, we can find the arcsin of 0.1. This gives us approximately 5.739 degrees.

However, since x is an acute angle, it means that x is between 0 and 90 degrees. The value 5.739 degrees falls within this range.

Therefore, the value of x in degrees, when sin(x) = 0.1 and x is an acute angle, is approximately 5.739 degrees.

Rounded to the nearest hundredth, the value of x would be 5.74 degrees.

It's important to note that the arcsin function has a range from -90 degrees to 90 degrees. In this case, since we are looking for an acute angle, we consider only the positive solution.

So, x = 5.74 degrees (rounded to the nearest hundredth) would be the appropriate answer for an acute angle satisfying sin(x) = 0.1.

For 7, To find the percentage of test takers that scored lower than Lorena, we need to find the area under the normal distribution curve to the left of her score of 554.

Using the standard normal distribution table, we can find the z-score corresponding to Lorena's score:

z = (x - μ) / σ = (554 - 495) / 20 = 2.95

Looking up the z-score of 2.95 in the standard normal distribution table, we find that the area to the left of this z-score is 0.9985.

Therefore, Lorena scored better than approximately 99.9% of the test takers, which we round to one decimal place as 99.9%.


On the 8th question, Given that the prices of bicycles are normally distributed with a mean (μ) of $208 and a standard deviation (σ) of $8, we need to find the percentage of bicycles priced greater than $203.

First, we need to calculate the z-score using the formula:
z = (X - μ) / σ
where X is the value we want to find the percentage for.

z = (203 - 208) / 8 = -0.625

Using a standard normal distribution table or calculator, we can find that the percentage of bicycles priced greater than $203 is 73.4% (rounded to one decimal place).

Therefore, approximately 73.4% of bicycles are priced greater than $203.

You want the left sum and the right sum of the four subinterval areas under the curve f(x) = √(x+3) on the interval [-1, 1].

Riemann sum

The Riemann sum is the sum of the subinterval areas. The area of each subinterval is the height of the rectangular area, multiplied by its width. Here, the interval width is (1 -(-1))/4 = 0.5.

The heights of the intervals of interest will be the function values f(-1 +0.5n) for f(x) = √(x+3) and n = 0 .. 3 for the left sum and 1 .. 4 for the right sum.

Janet Foster bought a computer and printer at Computer land. The printer had a $860 list price with a $100 trade discount and 2/10, n/30 terms. The computer had a $4,020 list price with a 25% trade discount but no cash discount. On the computer, Computer land offered Janet the choice of (1) paying $150 per month for 17 months with the 18th payment paying the remainder of the balance or (2) paying 6% interest for 18 months in equal payments.

a. Assume Janet could borrow the money for the printer at 6% to take advantage of the cash discount. How much would Janet save? (Use 360 days a year. Round your answer to the nearest cent.)



b. On the computer, what is the difference in the final payment between choices 1 and 2? (Round your answer to the nearest cent.)

Answers

Her savings would be $12.72 ($760 - $744.80 - $2.48).

The difference in the final payment is therefore $221.50 - $150 = $71.50.

How to solve

a. The printer's price after the trade discount is $760 ($860 - $100). If Janet takes the 2% cash discount, she'll pay $744.80 ($760 * 98%).

If she borrows this amount at 6% for 20 days (the difference between 30 days credit and 10 days cash discount), her interest cost will be $2.48 ($744.80 * 6% * 20/360).

Therefore, her savings would be $12.72 ($760 - $744.80 - $2.48).

b. For choice 1, Janet would pay $150 for 17 months and then the remainder ($4,020 * 75% - $150 * 17) in the 18th month.

For choice 2, the monthly payment is $221.50, calculated by using the formula for an installment loan.

The difference in the final payment is therefore $221.50 - $150 = $71.50.

Given is polynomial f(x) = 2xⁿ + ax² - 6, when divided by (x+3), the remainder is 129,

Calculating the values of a and n :-

From the question, we have the following parameters that can be used in our computation:

f(x) = 2xⁿ + ax² - 6 is divided by (x+3), the remainder is 129

This means that,

f(-3) = 129

So, we have

f(-3) = 2(-3)ⁿ + a(-3)² - 6

f(-3) = 2(-3)ⁿ + 9a - 6

2(-3)ⁿ + 9a - 6 = 129

2(-3)ⁿ + 9a = 135

Assume n = 3

So, we have

An isotope of cobalt-60, is used in medical therapy. When the radioisotope activity has decreased to 45% of its initial level, the exposure times required are too long and the hospital needs to replace the cobalt. How often does the cobalt need to be replaced if the half-life of cobalt-60 is 5.24 years? Round your answer to the nearest whole number

Answers

The hospital needs to replace the cobalt approximately every 2.16 years. Rounded to the nearest whole number, this is 2 years.

The half-life of cobalt-60 is 5.24 years, which means that after 5.24 years, the radioisotope activity will have decreased to 50% of its initial level. Since the hospital needs to replace the cobalt when the radioisotope activity has decreased to 45% of its initial level, this means that the cobalt needs to be replaced after slightly less than one half-life has passed.
To find out how long this is, we can use the formula:
t = (ln(0.45) / ln(0.5)) x 5.24
where t is the time in years since the cobalt was first used.
Using a calculator, we find that:
t ≈ 2.16 years
Therefore, the hospital needs to replace the cobalt approximately every 2.16 years. Rounded to the nearest whole number, this is 2 years.

Answers

The area of the small sector is (131/360) * pi * 3^2 = 3.422 cm^2 (rounded to 3 decimal places).

To find the area of the large sector, we need to subtract the area of triangle ADB from the area of the circle sector ACB. We can use the Law of Cosines to find the length of segment AD:

AD^2 = AB^2 + BD^2 - 2 * AB * BD * cos(ACB)
AD^2 = 3^2 + 2^2 - 2 * 3 * 2 * cos(131)
AD^2 = 13 - 12cos(131)
AD = sqrt(13 - 12cos(131))

The area of triangle ADB is (1/2) * AB * AD * sin(DAB) = (1/2) * 3 * sqrt(13 - 12cos(131)) * sin(49) = 1.786 cm^2 (rounded to 3 decimal places).

The area of the large sector is pi * 3^2 - 1.786 = 23.556 cm^2 (rounded to 3 decimal places).

Therefore, the area of the small sector is 3.422 cm^2 and the area of the large sector is 23.556 cm^2.

Answers

Elisa's savings account has the greater average rate of change between 2005 and 2015.

How to explain the rate

For Darlene's savings account, the initial amount in 2005 is $500. To calculate the value of the account in 2015, we need to know how many years have passed. Since 2015 is 10 years after 2005, we can substitute t = 10 into the equation given:

f(t) = 500(1 + 0.04t)

f(10) = 500(1 + 0.04(10))

f(10) = 500(1.4)

f(10) = 700

Therefore, the amount in Darlene's savings account in 2015 is $700. The average rate of change between 2005 and 2015 is the slope of the line connecting the points (0, 500) and (10, 700):

slope = (700 - 500) / (10 - 0) = 20

For Elisa's savings account, we are given the values of the function at several points, but we need to determine the slope of the line connecting the points (0, 600) and (10, 977), since this represents the change between 2005 and 2015. The slope is:

slope = (977 - 600) / (10 - 0) = 37.7

Therefore, Elisa's savings account has the greater average rate of change between 2005 and 2015.

Your income is R18 000 per month. How much can you pay on a house? (1)​

Answers

The amount more in income tax that Cho pays than Helen each month would be £56.

Here, we have,

First, find Helen's yearly salary :

= 1, 720 x  12

= £ 20, 640

Both Cho's and Helen's annual salaries fall within the Basic rate tax bracket.

Cho 's monthly tax would be:

= (( 24, 000 - 12, 570 ) x 20 % ) / 12

= £ 190. 50

Helen's monthly tax :

= (( 20, 640 - 12, 570 ) x 20 % ) / 12

= £ 134.50

The difference is therefore :

= 190. 50 - 134.50

= £56

Let Π be the plane containing the linex= 1 + 2t, y=−1 + 3t, z= 4 +t and parallel to the vector〈0,2,1〉.
(1) Find the equation of the plane Π.
(2) Find the equation of the plane Π1 that is parallel to Π and passes through (2,2,2).
(3) Find the distance between Π and Π1.

Answers

a) The equation of the plane is 2y + z - 2 = 0.

b) The equation of the plane Π1 that is parallel to Π and passes through (2,2,2) is 2y + z - 6 = 0.

c) The distance between the planes Π and Π1 is 4 / √6.

Given data ,

The given line has the parametric equations:

x = 1 + 2t

y = -1 + 3t

z = 4 + t

By comparing the coefficients of t, we can identify a point on the line, which is (1, -1, 4) when t = 0.

To find the normal vector to the plane Π, we use the fact that it is parallel to the vector ⟨0, 2, 1⟩. Since the normal vector is perpendicular to the plane, any vector parallel to the plane can serve as the normal vector. Therefore, we can take the vector ⟨0, 2, 1⟩ as the normal vector.

Now we have a point (1, -1, 4) on the plane Π and a normal vector ⟨0, 2, 1⟩.

The equation of the plane Π can be written as:

0(x - 1) + 2(y + 1) + 1(z - 4) = 0

Simplifying the equation gives:

2y + z - 2 = 0

So, the equation of the plane Π is 2y + z - 2 = 0.

(2)

To find the equation of the plane Π1 that is parallel to Π and passes through (2, 2, 2), we can use the same normal vector ⟨0, 2, 1⟩.

The equation of the plane Π1 can be written as:

0(x - 2) + 2(y - 2) + 1(z - 2) = 0

Simplifying the equation gives:

2y + z - 6 = 0

So, the equation of the plane Π1 is 2y + z - 6 = 0.

(3)

We can take the point (1, -1, 4) on the plane Π and find the perpendicular distance from this point to the plane Π1 using the equation of Π1.

The distance between the two planes is given by the formula:

Distance = |Ax₀ + By₀ + Cz₀ + D| / √(A² + B² + C²)

Using the point (1, -1, 4) and the equation of Π1: 2y + z - 6 = 0, we can substitute the values into the formula:

Distance = |(2)(-1) + (1)(4) - 6| / √(2² + 1² + 1²)

= |(-2) + 4 - 6| / √(4 + 1 + 1)

= |-4| / √6

= 4 / √6

Hence , the distance between the planes Π and Π1 is 4 / √6.

$150 reduced by 33 1/3%

Answers

Hello,

150 - 1/3% of 150

= 150 - 33,33% x 150

= 150 - 50

= 100

approximately 100

Example: 33 1/3% = 1/3. 1/3 of $150.00 = $50.00, so discounted price is: $150.00 - $50.00 = $100.00

El costo de un terreno es IP al cuadrado de la distancia que lo separa de Lima y DP a su área. Un terreno cuesta 540 mil y otro de doble área que está situado a una distancia 3 veces mayor que la distancia anterior, ¿qué precio tendrá?

Answers

Answer:60,000

Step-by-step explanation:

El costo de un terreno es IP al cuadrado de la distancia que lo separa de Lima y DP a su área. Esto se puede expresar como:

Costo = IP^2 * DP / Distancia^2

Sabemos que el costo de un terreno es de 540 mil, por lo que podemos escribir:

540,000 = IP^2 * DP / Distancia^2

Ahora consideremos el segundo terreno, que tiene el doble de área y está a una distancia 3 veces mayor que la del primer terreno. Si llamamos "Distancia anterior" a la distancia del primer terreno, entonces la distancia del segundo terreno es 3 veces la distancia anterior, es decir:

Distancia = 3 * Distancia anterior

Además, sabemos que el segundo terreno tiene el doble de área que el primero, por lo que podemos escribir:

Área = 2 * Área anterior

Reemplazando estas expresiones en la ecuación anterior, obtenemos:

Costo = IP^2 * DP / (3 * Distancia anterior)^2

Simplificando:

Costo = IP^2 * DP / 9 * Distancia anterior^2

Pero sabemos que el costo del segundo terreno es lo que estamos buscando. Llamemos "Precio del segundo terreno" a este valor. Entonces:

Precio del segundo terreno = IP^2 * DP / 9 * Distancia anterior^2

Como el costo del primer terreno es 540 mil, podemos reemplazar los valores conocidos:

540,000 = IP^2 * DP / Distancia anterior^2

Despejando IP^2, tenemos:

IP^2 = 540,000 * Distancia anterior^2 / DP

Reemplazando esta expresión en la ecuación anterior, obtenemos:

Precio del segundo terreno = (540,000 * Distancia anterior^2 / DP) * DP / 9 * Distancia anterior^2

Simplificando:

Precio del segundo terreno = 60,000 / DP * 2

Por lo tanto, el precio del segundo terreno es de 60,000 dividido por dos veces el valor de DP.

The numeric value of the derivative at x = 3 is given as follows:

C. 0.5.

How to obtain the derivative?

The quotient function has the format given as follows:

(f/g)(x).

The derivative of the function is obtained applying the quotient rule, as follows:

(f/g)'(x) = [f'(x)g(x) - f(x)g'(x)]/[g(x)]².

Then at x = 3, the derivative is given as follows:

(f/g)'(3) = [f'(3)g(3) - f(3)g'(3)]/[g(3)]².

Replacing the values from the table, we have that:

(f/g)'(3) = [3 x 2 - 1 x 4]/2².

(f/g)'(3) = 2/4

(f/g)'(3) = 0.5.

Meaning that the correct option is given by option C.
