A client asked Nathan to design a rectangular garden with an area of 22 square feet. The client also requested that the length of the garden be eight feet less than seven times the width
The length of the rectangular garden is 9.01 feet and width of the garden is 2.43 feet, if its area is 22 square feet.
Let the width of the garden be x units.
According to the given question.
The area of the rectangular garden is 22 square feet.
Also, the length of the garden be eight feet less than seven times the width.
⇒ length of the garden = 7x - 8
Thereofore, the area of the rectangular garden is given by
22 = x(7x - 8)
⇒ 22 = 7x^2 - 8x
⇒ 7x^2 - 8x - 22 = 0
⇒ x = [tex]\frac{8 \pm \sqrt{64 + 616} }{14}[/tex]
⇒ x = [tex]\frac{8 \pm \sqrt{680} }{14}[/tex]
⇒ x = [tex]\frac{8\pm 26}{14}[/tex]
⇒ x = 8 + 26/14
⇒ x = 34/14
⇒ x = 2.43 feet
So,
the length of the rectangular garden = 7(2.43) - 8 = 9.01 feet
Hence, the length of the rectangular garden is 9.01 feet and width of the garden is 2.43 feet, if its area is 22 square feet.

b. Raul learns that his data provider is iffy unlimited data plan for $59.99 per month. Find the minimum number if gigabytes Raul could use per month to make the unlimited plan cheaper than his current plan. Explain your solution process.
(a) The expression for Raul's monthly data costs is 29.99 + 10 (n - 5).
(b) The minimum number is 9 GB to make the unlimited plan cheaper.
The plan Raul chose has a monthly fee of $29.99 per month for 5 GB of data, with an additional cost of $10 for each gigabyte over 5.Assume that he will use "n" gigabyte per month.The monthly fee is $29.99 for 5 GB.The cost per GB after the first 5 GB is $10.The number of GB whose cost is $10 is (n - 5).His monthly fees = 29.99 + 10 (n - 5) ⇒ current planThe fees for the unlimited plan is $59.99 per month.We need an unlimited cheaper plan than the current one.Let the current plan be expensive than the unlimited plan.29.99 + 10 (n - 5) > 59.99Subtract 29.99 from both sides.10 (n - 5) > 30Divide both sides by 10.n - 5 > 3Add 5 to both sides.n > 8The minimum number is 9 GB to make the unlimited cheaper.To learn more about numbers, visit :

a local nonfrofit organization is selling popcorn to raise money for hurrican relief. the organization paid $4 per bag for the popcorn and sold $5 per bag. what was the percent makeup on each bag of popcorn?
The percent makeup on each bag of popcorn is 25%.
When a fraction of a whole is expressed as a number between 0 and 100, it is called a percentage. The percentages 100%, 50%, 0% indicate all of some quantity, half of the quantity, and none of the quantity respectively.
Popcorn is being sold by a neighborhood nonprofit to support hurricane relief.
The organization paid $4 for each bag of popcorn.
The organization sold each bag of popcorn for $5.
The markup or gain from selling the popcorn is:
$5 - $4 = $1
Therefore, the percent makeup on each bag of popcorn will be:
= ( the gain / the amount organization paid for each bag ) × 100
= ( 1 / 4) × 100
= 0.25 × 100
= 25 %
Hence, the percent makeup on every bag of popcorn is 25%.

Rewrite 8x + 64 using a common factor.
8x(x + 64)
8x(x + 8)
8(x + 64)
8(x + 8)
The expression (8x+64) can be rewritten as a common factor as 8(x+8).
According to the question,
We have the following expression:
(8x+64)
It is to be noted that a common factor is such a number including a variable that it can completely divide a term. For example, in this expression, 8 is such a number that it can divide both 8x as well as 64.
(This can be better understood using more examples. For example, 4 is a common factor in 4x+24 and 5 is a common factor in 5x+30.)
Now, taking 8 as a common factor:
8 (x+8)

What is the range of the function f(x)=6x^2+x-1/2x^2+x-6
Answer:
Range: [tex]\:f\left(x\right)\ge \:-\frac{68}{11}[/tex]
Interval notation [tex][-\frac{68}{11},\:\infty \:)[/tex]
Step-by-step explanation:
I got a little confused with the x - 1/2x^2 term and I am taking to to be:
[tex]x\:-\frac{1}{2}x^2[/tex] . If this is incorrect please mention the correct term in your comment and I will edit this post. Or you can re-post the question
We have
[tex]f\left(x\right)=6x^2+x\:-\frac{1}{2}x^2+\:x\:-\:6[/tex]
Simplify by grouping like terms:
[tex]=-\frac{1}{2}x^2+6x^2+x+x-6[/tex]
[tex]= \frac{1}{2}x^2+6x^2+2x-6[/tex]
Add similar elements
[tex]-\frac{1}{2}x^2+6x^2[/tex][tex]= -\frac{1x^2}{2}+\frac{12x^2}{2} = \frac{11x^2}{2}[/tex]
So the original function expression becomes
[tex]y=\frac{11}{2}x^2+2x-6[/tex]
This is the equation of a parabola which in standard form is [tex]ax^2 + bx + c[/tex]
Here
[tex]a=\dfrac{11}{2},\:b=2,\:c=-6[/tex]
We can compute the vertex of this parabola using the fact that the x, y coordinates of the vertex are given by
[tex]x_v =-\dfrac{b}{2a}[/tex]
Plugging in values for b and a give us
[tex]x_v =-\dfrac{b}{2a} = -\dfrac{2}{2\left(\dfrac{11}{2}\right)} =-\dfrac{2}{11}[/tex]
Plugging in this value of [tex]x_v[/tex] into the parabola equation will give the value for [tex]y_v[/tex] which is the function value at the vertex
Plug in [tex]x_v = -\frac{2}{11}[/tex] t find the [tex]y_v[/tex] value:
[tex]y_v=\dfrac{11\left(-\dfrac{2}{11}\right)^2}{2}+2\left(-\dfrac{2}{11}\right)-6[/tex]
Simplify
[tex]\dfrac{11\left(-\dfrac{2}{11}\right)^2}{2} =\dfrac{2}{11}[/tex]
[tex]2\left(-\dfrac{2}{11}\right) = -\dfrac{4}{11}[/tex]
Combining the terms we get
[tex]y_v =[/tex] [tex]\dfrac{2}{11}-\dfrac{4}{11}-6[/tex] [tex]= -\dfrac{68}{11}[/tex]
[tex]\textsf{Therefore the parabola vertex is at }[/tex] [tex]\left(-\dfrac{2}{11},\:-\dfrac{68}{11}\right)[/tex]
For a parabola of the form [tex]ax^2 + bx + c[/tex] with vertex [tex]\left(x_v,\:y_v\right)[/tex]
[tex]\circ \;\mathrm{If}\:a < 0\:\mathrm{the\:range\:is}\:f\left(x\right)\le \:y_v[/tex]
[tex]\circ \;\mathrm{If}\:a > 0\:\mathrm{the\:range\:is}\:f\left(x\right)\ge \:y_v[/tex]

Answer range of f(x) is

polygon b is a scaled copy of polygon a using a scale factor of 5 . polygon a area is what fraction of polygon b area
The area of polygon A would be a fraction 1/25 of the size of polygon B.
What is a scale image?Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions on the actual figure or object
The formula of the scale factor is shown as;
Area of Polygon B = (scale factor)²×(Area of Polygon A).
Using a scale factor of 5, we get
(Area of Polygon B) = (5)²× (Area of Polygon A)
(Area of Polygon B) = (25) × (Area of Polygon A)
Area of Polygon A = (1/25) × Area of Polygon B

Find the equation of the line that passes through the points (1, 3) and (2, 4)
Answer:
y = x + 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, 3 ) and (x₂, y₂ ) = (2, 4 )
m = [tex]\frac{4-3}{2-1}[/tex] = [tex]\frac{1}{1}[/tex] = 1 , then
y = x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (1, 3 )
3 = 1 + c ⇒ c = 3 - 1 = 2
y = x + 2 ← equation of line
Under his cell phone plan, Carson pays a flat cost of $37.50 per month and $3 per gigabyte. He wants to keep his bill under $40 per month. Which inequality can be used to determine g, the maximum number of gigabytes Carson can use while staying within his budget?
Based on the flat cost paid by Carson for his cell phone plan, and the amount of he wants to keep his bill under, the inequality that can be used to determine g is 37.50 + 40g ≤ 40
How to find the inequality?The inequality that can be used to find the maximum number of gigabytes that Carson can use while staying in his budget can be found as:
Flat cost for the cell phone plan + Cost per gigabyte x Number of gigabytes ≤ Maximum preferred bill by Carson
When we put in the figures from Carson's cell phone plan, we get:
37.50 + 3 x g ≤ 40
37.50 + 3g ≤ 40

1. x + x = 10
2. y + z= 9
3. y+ x = 8
solving equation 1
x + x = 10
2x = 10
x = 5
Putting the value of x in equation 3
y + x=8
y + 5 = 8
y = 3
Putting the value of y in equation 2
y + z = 9
