Applying the triangle proportionality theorem, the length of line EC is: 7.2 units.

How to Apply the Triangle Proportionality Theorem?

Since lines AC and DE are parallel to each other in the triangle, and DE intersects sides AB and AC, then we would have the following proportion based on the triangle proportionality theorem:

BD/DA = CE/EA

BD = 18 units

DA = 15 units

CE = ?

EA = 6 units

Plug in the values

18/15 = CE/6

(18)(6) = (CE)(15)

108 = CE(15)

Divide both sides by 15

108/15 = CE(15)/15

7.2 = CE

EC = 7.2 units

Therefore, applying the triangle proportionality theorem, the length of line EC is: 7.2 units.

What is walmart's ebit for the year of 2018 (round it to 3 numbers after the decimal point -> 0.581)?

Answers

Walmart's EBIT for the year 2018 is $17,101.

What is EBIT?Earnings before interest and taxes (EBIT) is a measure of a company's profit that includes all income and expenses (operating and non-operating) except interest and income tax expenses (for individuals).When a company does not have non-operating income or non-operating expenses, operating income and operating profit are sometimes used as synonyms for EBIT.

To find Walmart's EBIT:

9,862 + 661+ 4,600 + (1,826 + 152) = $17,101

The diagram shows a solid triangular prism with a cylindrical hole of radius r cm drilled through it. (i) The ratio of the volume of solid removed : volume of remaining solid is 1 : 6. Find the value of r. Using your answer in part (i), find the total surface area of the solid shown. ​

Answers

The value of the radius r is 9.35 cm.

The dimensions of the triangular prism is 62 cm × 62 cm × 85 cm.

The volume of the prism will be:

Volume = (1/2) × 62 × 62 × 85

Volume = 163370 cm³

Now,

The volume of solid removed: The volume of remaining solid = 1 : 6

Therefore,

The solid removed = ( 1 / 7 ) of the total volume

Solid removed = ( 1 / 7 ) × 163370

Solid removed = 23338.57 cm³ which is the volume of the cylindrical hole.

Now, the volume of the cylinder is:

V = π (r)² h

23338.57 = π (r)² × (85)

23338.57 = (3.142) × (r)² × (85)

23338.57 = 267.1 r²

r² = 87.38

r = √(87.38)

r = 9.35 cm

The surface area of the triangular prism:

A = (1/2) (b) (h)

A = (1/2) (85)(62)

A = 2653 cm²

The width of a rectangle is 3 less than its length find the width of the rectangle if its perimeter is 26ft

Answers

The width of rectangle is 5 feet.

Let us assume the length of rectangle to be x. So, the width of rectangle will be (x - 3).

Now, as per the known fact, perimeter, length and width of rectangle are related by the formula -

Perimeter = 2 × (length + width)

Keep the values in formula to find the value of width

26 = 2 × (x + x - 3)

Performing addition of variables inside the bracket

26 = 2 × (2x - 3)

Shifting 2 to other side of equation to find the value of x

2x - 3 = [tex]\frac{26}{2}[/tex]

Performing division to find the value of x

2x - 3 = 13

Shifting 3 to other side of equation to find the value of x

2x = 13 + 3

Performing addition to find the value of x

2x = 16

Shifting 2 as denominator to other side of equation to find the value of x

x = [tex]\frac{16}{2}[/tex]

Performing division to find the value of x

x = 8

So, length of rectangle is 8 feet

Width of rectangle = x - 3

Width of rectangle = 8 - 3

Width of rectangle = 5 feet

Hence, the width of rectangle is 5 feet.

The perimeter of a rectangle is 800 yards. What are the dimensions of the rectangle if the length is 50 yards more than the
width?

Answers

Answer:

The length is 225 yd, and the width is 175 yd.

Step-by-step explanation:

Let w = width.

Then the length = w + 50.

perimeter = 2(length + width)

800 = 2(w + 50 + w)

400 = 2w + 50

2w = 350

w = 175

w + 50 = 225

The length is 225 yd, and the width is 175 yd.

Answer:

225 * 175 yards,

Step-by-step explanation:

If the width is x then the length is x+50.

Perimeter = 2(width + length)

800 = 2( x + x + 50)

2x + 50 = 400

2x = 350

x = 175

So, the width is 175 yd and length is 225yd.

In the coordinate plane, the point X (2, 2) is translated to the point X (0, 4). Under the same translation, the points Y(-2, 0) and Z (0, 6) are
translated to Y and Z', respectively. What are the coordinates of Y' and Z?

Answers

The points Y and Z after transition are (-4,-2) and (-2,4)

In this case, we are required to find x' and y' to find the direction of transition

x' =x coordinate of point 2 - x coordinate of point 1

   = 0-2 = -2

y'= y coordinate of point 2 - y coordinate of point 1

   =4-2 = 2

Now we are required to  subtract these transition from the points given,

Transition of point Y = (-2-2 ,0-2)  =(-4,-2)

Transition of point Z =(0-2,6-2)  = (-2,4)

Hence the points after transition are  Y as(-4,-2) and Z as (-2,4)

As per the information in the question,

cos(t) = 2/9

As we know that cos θ = B/H

B = 2 and H = 9

Now, use Pythagoras's theorem,

H² = P² + B²
