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:

BA

Step-by-step explanation:

Here, we want to get the hypotenuse side

The hypotenuse represents the longest side

it is the side that faces the largest angle in a right triangle

The largest angle in a right triangle is the right angle which is the angle 90

It is like the square at a corner at the vertex C

The side facing it here is the the length AB (BA)

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

Step-by-step explanation:

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:

Henry can write 10 pages in 8 hours.

Step-by-step explanation:

Our unit rate (number of pages in a given number of hours) is

5 pages

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

   4 hrs

It is not necessary to perform the indicated division.  Just multiply this unit rate by '8 hours':

5 pages

-------------- * 8 hrs = 10 pages

   4 hrs

Henry can write 10 pages in 8 hours.

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

Answer:

1) Since Manuel bought 9 pounds and ate 3/4 of 1 pound, he has 8.25 pounds left   (9  - 0.75  = 8.25)

 2) Let's call "x" the cost of 1 pound of apples

 3) (8.25)*(x) = $15

 4) x = $1.81818    rounded to the nearest dollar is $2 / pound

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:

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]
