A contractor isn't darling carpet in the new house direct angular living room has an area of 96 ft.² and the link is 12 feet less than three times the width of the room what are the dimensions of the room

Answers

Answer:

The dimensions of the room is 8 feet × 12 feet.

Step-by-step explanation:

The area of the house, A = 96 ft²

The link is 12 feet less than three times the width of the room .

Let the width of the room is x.

Length = 3x-12 ...(1)

The area of a rectangular room is given by :

A = lb

96 = (3x-12)x

[tex]3x^2-12x-96=0\\\\x^2-4x-32=0\\\\x^2-8x+4x-32=0\\\\x(x-8)+4(x-8)\\\\(x+4)(x-8)=0\\\\x=-4,8[/tex]

Neglecting negative value, width = 8 feet

Put x = 8 in equation (1)

Length = 3(8) - 12

= 12 feet

Hence, the dimensions of the room is 8 feet × 12 feet.

Yuri purchased 8 trees to have planted at his house. The store charged a delivery fee of $5 per tree.

The total cost of the trees including the delivery was $168.

How much did each tree cost?

Enter your answer in the box.

Answers

Answer:

The answer would be 16, because the delivery of the 8 trees costed 40, and the overall cost was 168, so you would subtract 40 for the delivery, and divide 128 by 8.

Step-by-step explanation:

Answer:

128

Step-by-step explanation:

If the delivery was 168 in total the fee was also in there. 8x5=40 so thats the fee. Subtract that from 168 which is 128. So the cost of the trees total was 128 but the total cost of the fee is 168. Hope this helped.

Mr.Williams, a parking lot owner, sold 20% of his lot to his neighbor. Later that year he sold 20% of the remainder of his lot to another neighbor. What percent of Mr.Williams' original parking lot does he still own?

Answers

Answer: He still owns 64% of the Mr.Williams' original parking.

Step-by-step explanation:

Let x = Area of the original parking plot.

First he sold 20% of his lot to neighbor .

Sold plot = 20% of x = 0.20x  [Replace 'of' by '×' and divide number by 100 to remove %]

Reminder= x-0.20x= (1-0.20)x=0.80x

Again he sold 20% of the remainder .

Sold plot = 20% of (0.80x) = 0.20 (0.80x)

= 0.16x

Remainder plot = 0.80x-0.16x= 0.64x

Percent of Mr.Williams' original parking lot does he still own = [tex]\dfrac{0.64x}{x}\times100=64\%[/tex]

Hence, he still owns 64% of the Mr.Williams' original parking.

Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution.
-x+y=1
-2x -y=-4

Answers

Answer:

One solution:(1,2)

Step-by-step explanation:

   y = x + 1

/Plug this in for variable  y  in equation [2]

  -2x - (x +1) = -4

  -3x = -3

Solve equation [2] for the variable  x  

 3x = 3  

    x = 1  

By now we know this much :

   x = 1

   y = x+1

Use the  x  value to solve for  y  

   y = (1)+1 = 2

How to calculate the modular function?

Among modular functions, f(x) = |x| has its domain given by the real numbers and its range given by the positive real numbers. This is because the modular function will make |-y| = -(-y) = y given every negative y-value.

Given modular function is :

y = -|x + 4| - 5.

Hence, to plot the graph of a modular function, we need to determine some values for x and then apply them to the function f(x) = | x |.

Find the value of x​

Answers

Answer:

x = 70

y = 110

z = 30

Step-by-step explanation:

all triangles add up to 180

30 + 80 = 110

180 - 110 = 70

x = 70

30 + 40 = 70

70 + 80 = 150

180 - 150 = 30

z = 30

40 + 30 = 70

180 - 70 = 110

y = 110

x=6, y=21/2

Explanation

The 86 degrees is just to make you confused.

Since this is a congruent triangle, you can just follow these steps.

Line AB: To get from 4 to 6, you multiply by 1.5.

Line BC: Divide 9 by 1.5 to get x. 9 divided by 1.5 is 6.

Line AC: Multiply 7 by 1.5 to get y. 7 times 1.5 is 10.5.

So the correct answer is the first choice; x=6, y=21/2 (this is also 10.5).

Step-by-step explanation:

Given the expression

[tex]2x+329[/tex]

We know that range is termed as the set of values of the dependent variable for which a function is defined.

We also know that the range of polynomials with odd degree is all the real numbers.

       i.e. [tex]-\infty \:<f\left(x\right)<\infty \:[/tex]

The given expression is a polynomial with an odd degree. Hence, the range of this expression will be all the real numbers.

Thus, the range of 2x+329:

[tex]\mathrm{Range\:of\:}2x+329:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<f\left(x\right)<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]
