Answer:

Triangle BDE and triangle BAC are similar triangles

Hence, two lines DE and AC are parallel to each other

Step-by-step explanation:

For proving that DE is parallel to AC, we are required to prove that triangle BDE and triangle BAC are similar triangles

The ratio of sides of both the triangle must be equal to each other

Hence

[tex]\frac{BE}{DB} = \frac{BC}{BA} \\\frac{16.1}{28} = \frac{20.7+16.1}{64}\\0.575 = 0.575[/tex]

and angle B is common.

Hence the two triangles are similar.

Therefore angle BDE and angle BAC are equal like wise angle BED and angle BCA are equal.

Thus, the two lines DE and AC are parallel to each other

Answer:

It’s 64 x 9 equals 576

Step-by-step explanation:

The answer is 9 feet

The value height of shed is 9 feet.

The volume of a rectangular prism is defined as the space occupied within a rectangular prism. A rectangular prism is a polyhedron that has two pairs of congruent and parallel bases.

Here, Vol. of rectangular prism = 576 ft³

          base area = 64 ft²

Volume of rectangular prism = area of base X height

      576 = 64 X h

        h = 576 / 64

       h = 9 ft.

Thus, the value height of shed is 9 feet.

Answer:

71

Step-by-step explanation:

214/3

Answer:

I got x=10

Step-by-step explanation:

Step 1

Everything must add up to 180

180= 6x - 6 + 7x + 1 +55

Step 2

Combine everything

6x + 7x = 13x

-6 + 1 +55 =50

180 = 13x + 50

Step 4

Subtract. 180 -50

130 = 13x

Step 5

Divide 130/13

X=10

6(10) -6 = 54

7(10) + 1=71

Answer:  YESSS  A line is increasing if it goes up from left to right. The slope is positive.  A line is decreasing if it goes down from left to right.

Step-by-step explanation:    The concept of slope is very useful in economics, because it measures the relationship between two variables. A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y also decreases.

Answer:

3 1/3 = 10/3

0.3 = 3/10

a * 1/a =1

then 1/a is multiplicative inverse of a

0.3* 3 1/3 = 3/10 * 10/3 =1

0.3 is multiplicative inverse of 3 1/3

Step-by-step explanation:

Answer:

3 1/3 = 10/3

10.3 = 0.3 = 3 1/3

x * 1/x = 1

∴ yes, the multiplicative reverse of 3 1/3 is 0.3

Answer:

mass=180kg and the volume=6m³.

then the formula to find density is= mass/volume

using this formula,180kg/6m³=30kg/m³

Answer:

8 m³

Step-by-step explanation:

Let v represent the volume.  Recall that density is mass/volume, which here is 0.9 kg/m³.  To find the volume of this object, divide the density into the mass:

 7.2 kg

--------------- = 8 m³

0.9 kg/m³

Answer:

[tex](a)\ k_2 = 1in:3ft[/tex]

[tex](b)\ Scale\ width =\frac{16}{3}\ in[/tex]

Step-by-step explanation:

Given

[tex]k_1 = 1in : 2ft[/tex] --- Initial scale factor

[tex]Blueprint: 12in\ by\ 8in[/tex] --- Missing from the question

Solving (a): The new scale factor.

Convert the initial blueprint to actual measurement using the initial scale factor, we have:

[tex]Length = 12 * 2ft = 24ft[/tex]

[tex]Width = 8 * 2ft = 16ft[/tex]

From the question, we understand the new scale factor represents the width as 8in.

The scale factor (k2) is then calculated as:

[tex]k_2 = \frac{Scale\ length}{Actual\ length}[/tex]

[tex]k_2 = \frac{8in}{24ft}[/tex]

Simplify

[tex]k_2 = \frac{1in}{3ft}[/tex]

Represent as fraction

[tex]k_2 = 1in:3ft[/tex]

The above is the new scale factor

 Solving (b): The new width

Using the scale factor above we have:

[tex]k_2 = \frac{Scale\ width}{Actual\ width}[/tex]

[tex]\frac{1in}{3ft} = \frac{Scale\ width}{16ft}[/tex]

The 16 is gotten from:

[tex]Width = 8 * 2ft = 16ft[/tex]

So, we have:

[tex]Scale\ width = 16ft * \frac{1in}{3ft}[/tex]

[tex]Scale\ width = 16 * \frac{1in}{3}[/tex]

[tex]Scale\ width =\frac{16\ in}{3}[/tex]

[tex]Scale\ width =\frac{16}{3}\ in[/tex]

Hence, the scale width of the blueprint is: 16/3 inches

Answer: Part A is 3 and part b is 5 1/3 inches

if it wants the measurement of arcJK....

Answer:

ArcJK= 128

Step-by-step explanation:

Circle is 360 degrees

<KL is the diameter which is a straight line equals 180 degrees

Since <KLis also a central angle arcKL equals 180

Take <K (26) and times by two cause its an inscribe angle, 26*2=52

arcJL=52

add both arcKL and arcJL together: 180+52=232

then you take 360-232=128

and 128 is KLarc

Answer: Pat bonces the ball 125 times in 150 seconds.

Answer:

1. (5x - 2) + (2x - 2) + x = [tex]180^{o}[/tex]

2. m<J = [tex]113^{o}[/tex]

3. m<K = [tex]44^{o}[/tex]

4. m<L = [tex]23^{o}[/tex]

Step-by-step explanation:

Generally, the sum of angles in a triangle = [tex]180^{o}[/tex].

So that;

m<J + m<K + m<L = [tex]180^{o}[/tex]

(5x - 2) + (2x - 2) + x = [tex]180^{o}[/tex]

5x + 2x + x -2 -2 = [tex]180^{o}[/tex]

8x - 4 = [tex]180^{o}[/tex]

8x = [tex]180^{o}[/tex] + 4

8x = 184

x = [tex]\frac{184}{8}[/tex]

x = [tex]23^{o}[/tex]

Thus,

m<J = (5x - 2)

       = 5(23) - 2

       = [tex]113^{o}[/tex]

m<K = (2x -2)

        = 2(23) - 2

        = [tex]44^{o}[/tex]

m<L = x

       = [tex]23^{o}[/tex]
