The area of a rectangular wall of a barn is 135 square feet. It's length is 6 feet longer than a width. Find the length and width of the wall of the barn

Answers

Answer: [tex]15\ ft,6\ ft[/tex]

Step-by-step explanation:

Given

The area of a rectangular wall of a barn is [tex]135\ ft^2[/tex]

Suppose the width of the wall is [tex]x[/tex]

So, the length of the wall is [tex]6+x[/tex]

Area can be written as the product of length and width

[tex]\Rightarrow (6+x)x=135\\\Rightarrow 6x+x^2=135\\\Rightarrow x^2+6x-135=0\\\Rightarrow x=\dfrac{-6\pm \sqrt{6^2-4(1)(-135)}}{2(1)}\\\\\Rightarrow x=\dfrac{-6\pm 24}{2}\\\\\Rightarrow x=-15,9[/tex]

neglecting the negative value, width of the wall is [tex]9\ ft[/tex]

So, the length of the wall is [tex]9+6=15\ ft[/tex]

Which equations can pair with y = 3x – 2 to create a consistent and independent system? x = 3y – 2 y = –3x – 2 y = 3x + 2 6x – 2y = 4 3y – x = –2

Answers

Answer:

[tex](a)\ x = 3y - 2[/tex]

[tex](b)\ y = -3x - 2[/tex]

[tex](e)\ 3y - x = -2[/tex]

Step-by-step explanation:

Given

[tex]y =3x -2[/tex]

Required

Equations that can create consistent and independent systems

For a pair of equation to have consistent and independent systems, the equations must have different slopes.

An equation of the form [tex]y = mx + c[/tex] has m has its slope.

In [tex]y =3x -2[/tex]

[tex]m = 3[/tex] --- slope

Considering the options

[tex](a)\ x = 3y - 2[/tex]

Make y the subject

[tex]x = 3y - 2[/tex]

[tex]3y = x+2[/tex]

Divide by 3

[tex]y = \frac{1}{3}x+\frac{2}{3}[/tex]

The slope is:

[tex]m_1 = \frac{1}{3}[/tex]

Hence, (a) can make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](b)\ y = -3x - 2[/tex]

The slope is:

[tex]m= -3[/tex]

Hence, (b) can make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](c)\ y = 3x + 2[/tex]

The slope is:

[tex]m=3[/tex]

Hence, (c) cannot make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](d)\ 6x - 2y = 4[/tex]

Make y the subject

[tex]2y = 6x -4[/tex]

Divide by 2

[tex]y = 3x -2[/tex]

The slope is

[tex]m =3[/tex]

Hence, (d) cannot make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](e)\ 3y - x = -2[/tex]

Make y the subject

[tex]3y = x -2[/tex]

Divide by 3

[tex]y = \frac{1}{3}x -\frac{2}{3}[/tex]

The slope is:

[tex]m = \frac{1}{3}[/tex]

Hence, (e) can make a consistent and independent system with [tex]y =3x -2[/tex]

Answers

Answer:

lesser x = -6

greater x  = 6

Step-by-step explanation:

-5x² + 180 = 0

5x² = 180

x² = 36

x = ±6

Answer:

x = - 6, x = 6

Step-by-step explanation:

Given

h(x) = - 5x² + 180

To find the zeros let h(x) = 0 , that is

- 5x² + 180 = 0 ( subtract 180 from both sides )

- 5x² = - 180 ( divide both sides by - 5 )

x² = 36 ( take the square root of both sides )

x = ± [tex]\sqrt{36}[/tex] = ± 6 , then

lesser x = - 6

greater x = + 6

The ratio of the dimensions of the model to the dimensions of the Great Pyramid is about 1 to 38. The surface area of the real pyramid is about how many times the surface area of the model.
Dimensions: a pyramid with a square base.
base sides: 6m
height: 4m

Answers

Answer:   1444

========================================================

Explanation:

Consider a square on paper that is 3 inches by 3 inches. It's area would be 3*3 = 9 square inches.

The ratio 1 to 38 means that 1 inch on paper corresponds to 38 inches in real life (assuming the "1 to 38" doesn't have any verbal units attached to it; if so, then refer to the note below). So a 3 by 3 square corresponds to a 114 by 114 square because 3*38 = 114.

The area of the second larger square is 114*114 = 12,996 square inches.

Now divide the two areas: (12,996)/(9) = 1444

It's probably not entirely obvious, but through a bit of playing around with various numbers, you should find that 38^2 = 1444. It's not a coincidence that this happens. The linear scale factor is 38 which means the area scale factor is 38^2 = 1444.

In short, the larger square in real life has area that is 1444 times that of its scaled down counterpart.

Or put another way:

large area = 1444*(small area)

------------------

Side note: This all assumes that the numbers in "1 to 38" are both the same unit. If we had a mixed ratio of units like "1 inch to 38 feet", then the answer would be different. You would need to convert from feet to inches, and then follow the steps above to get a different answer.

Answer:

(x - 3)² + (y + 5)² = 10

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (3, - 5 ) , then

(x - 3)² + (y - (- 5) )² = r² , that is

(x - 3)² + (y + 5)² = r²

r is the distance from the centre to a point on the line

Calculate r using the distance formula

r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (3, - 5) and (x₂, y₂ ) = (6, - 4)

r = [tex]\sqrt{(6-3)^2+(-4+5)^2}[/tex]

  = [tex]\sqrt{3^2+1^2}[/tex]

  = [tex]\sqrt{9+1}[/tex]

   = [tex]\sqrt{10}[/tex] ⇒ r² = ([tex]\sqrt{10}[/tex] )² = 10

(x - 3)² + (y + 5)² = 10 ← equation of circle

Answers

Answer:

49N

Step-by-step explanation:

Below is the calculation for the force applied:

It is given that the mass of stone is 5 kg and it falls from the height of 100 meters. Therefore, a force can be determined by multiplying the mass will a constant value of "a".

Force = Mass x a

Force = 5 x 9.8

Force = 49 N

Answers

Answer:

35

Step-by-step explanation:

Cause they both add up to a right angle which is 90 degrees. so 90-55=35

angle, a and ∠angle, b are complementary angles. ∠ an ∠angle, a measures 5 5 ∘ 55 ∘ 55, degrees. so we can conclude that ∠b = 35.

What is the angle sum property?

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

angle, a and ∠angle, b are complementary angles.

∠ an ∠angle, a measures 5 5 ∘ 55 ∘ 55, degrees.

we want to measure ∠ b

We know that the sum of Complementary angles is equal to 90 degrees.

so to find the measure of angle B we subtract the given angle from 90

∠ b + ∠ a = 90

∠ b + 55 = 90

∠ b = 90-55

∠ b =35

so we can conclude that ∠b = 35.

Write an equation of the line that passes through the point (4,5) and has a slope of -2.

Answers

Answer:

y = - 2x + 13

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 )

Here m = - 2 , then

y = - 2x + c ← is the partial equation

To find c substitute (4, 5) into the partial equation

5 = - 8 + c ⇒ c = 5 + 8 = 13

y = - 2x + 13 ← equation of line

Answer:

Step-by-step explanation:

slope=-2

now using slope intercet formof equation of straight line,we get

y=mx+b

or, y=-2x + b

y + 2x =b

2x + y=b ......................   eq(i)

since the line passes through the point (4,5) it satisfies the equation (i)

y=5 and x=4 so,

equation is 2x +y =b

2*4 + 5=b

8+5=b

13=b

substituting the value of b in eq(i)

2x + y=b

2x + y=13

2x + y-13=0  is the required equation of the line.

If that were the case, you'd imagine the employer would go to great lengths to find, attract, and retain quality employees. Couple this goal with the reality of the economic picture -you simply cannot afford to provide expensive benefits for employees who may leave you for a different employer offering an extra $1,000 in salary or benefits. Knowing that 41 percent of all employees have no loyalty to their employers and will move on if a better offer comes adds to the dilemma. These issues clearly are a concern for organizations like Genentech or Zappos. But they don't fret over them. That's because they have found that treating employees with respect, and giving them such things as bonuses, rewards for longevity, onsite child care, lunches, and sending employees home with prepared dinners really works. Genentech is a California company that "develops and produces drugs that cure diseases," according to the company website. The company celebrated its thirteenth year on Fortune's "Best Places to work" list in 2011, also receiving "Best Places to Work" honors from Working Mother, LGBT Equality, and Computerworld. The reasons for this recognition are the important work that they do and the strong company culture that values equality and communication. Any discussion of how great it is to work at Genentech always circles back to the benefits that show a real respect for employees. In addition to traditional benefits like retirement and healthcare, they provide family friendly perks such as unlimited sick leave, personal concierge service, flexible work scheduling, childcare, nursing mother's rooms, onsite nurses, adoption assistance, and company sponsored family events. The list of innovative benefits goes on to include unusual benefits like pet insurance, free snacks, and paid six-week sabbaticals every six years! Zappos, the online shoe retailer, offers perks that match their fun-loving culture like pajama parties, nap rooms, regular happy hours, and a full-time life coach.
