The length of segment DC is given by the law of sines and trigonometric ratios as approximately 11.3 cm

The law of sines states that in a triangle, the ratio of the sine of an interior angle of a triangle to the length of the side opposite the angle is constant.

The given parameters are;

The figure ABC is a triangle

The figure ADC is a straight line segment

Segment BD is perpendicular to segment AC

The length of segment AB = 8 cm

Length of segment BC = 12 cm

The measure

[tex] \angle ABD = 60^{ \circ} [/tex]

Required;

The length of segment DC

Solution;

[tex] \angle ADB = 90^{ \circ} [/tex]

Definition of segment BD being perpendicular to segment AC

[tex] \angle BAC = 90^{ \circ} - 60^{ \circ} = 30^{ \circ}[/tex]

Using the law of sines, we have;

[tex]AD = AB × sin( \angle ABD) [/tex]

A vertex of the triangle from the question is point B

Which gives;

AD = 8 × sin(60°) = 4•√3

Similarly, from the law of sines, we have;

[tex]\displaystyle{\frac{BC}{sin ( \angle BAC)} = \frac{AB}{sin ( \angle BCA)} } [/tex]

Which gives;

[tex] \displaystyle{\frac{12}{sin ( 30^{ \circ})} = \frac{8}{sin ( \angle BCA)} } [/tex]

[tex] \displaystyle{ sin ( \angle BCA) = \frac{sin ( 30^{ \circ}) \times 8}{12}= \frac{1}{3} }[/tex]

[tex] \displaystyle{ \angle BCA = arcsine \left(\frac{1}{3}\right) }[/tex]

[tex] \displaystyle{DC= 12 \times cos\left(arcsine \left(\frac{1}{3}\right)\right) = 8\cdot \sqrt{2}}[/tex]

Therefore, DC = 8•√2 ≈ 11.3

Explanation:

Think of a roller coaster. A sharp drop is where we have a very steep decline. The steeper the line, the more rapid the drop.

The same can be said for when the graph increases as well.

Horizontal portions of the graph are when the elevator isn't moving. The x value (time) is always moving forward of course, but the y value (height of the elevator) is not changing.

The value of y in the expression (21y-1)=(4x+23)(9x-38) is (103x - 875)/21.

According to the given question

We have a linear equation in two variables

(21y - 1) = (4x + 23)(9x -38)

For finding the value of y solve the above equation by adding and subtracting the like terms.

So, 21y - 1 = 4x(9x -38) + 23 (9x -38)

⇒ 21y - 1 = 48x - 152x + 207x - 874

⇒ 21y - 1 = 103x - 874

⇒ 21y = 103x - 874 + 1

⇒ 21y = 103x - 875

⇒ y =  [tex]\frac{103x - 875 }{21}[/tex]

Hence, the value of y in the expression (21y-1)=(4x+23)(9x-38) is [tex]\frac{103x - 875 }{21}[/tex]

The opposite angles of a parallelogram are equal.

x + y = a+ b

Let's consider a quadrilateral ABCD which is a parallelogram with AC as its diagonal.

We know, in parallelograms opposites' sides are parallel.

So, AB∥DC and AD∥BC

Since AB is parallel to DC and AC is the transversal.

By alternate angles,

∠BAC = ∠DCA

y = a                                                                                           -----------------(1)

Similarly, AD is parallel to BC and AC is the transversal.

The alternate angles,

∠DAC = ∠BCA

x = b                                                                                           -----------------(2)

Adding equations ( 1 ) and ( 2 ),

∠BAC + ∠DAC = ∠DCA + ∠BCA

∠BAD = ∠DCB

x + y = a + b

Similarly, we can prove, ∠ADC=∠ABC

Hence proved, opposite sites of a parallelogram are equal.

Through the unitary method, we get that 8000 tons of petrochemicals are required to produce 5,000 tons of plastic.

A problem can be solved using the unitary method by first determining the value of a single unit, and then multiplying that value to determine the required value.

Given :

160,000 tons of petrochemicals are required to produce 100,000 tons of plastic.

160,000 tons of petrochemicals produces = 100,000 tons of plastic.

To produce 1 ton of plastic, the required amount of petrochemicals = [tex]\frac{160,000}{100,000} = \frac{8}{5}[/tex] tons...........equation (1)

Let x be the tons of petrochemicals required to produce 5,000 tons of plastic.

Multiplying 5,000 tons on both sides of the equation, we get :

To produce 5,000 tons of plastic =[tex]\frac{8}{5}*5000 = 8000[/tex] tons of petrochemicals

Hence, 8000 tons of petrochemicals are required to produce 5,000 tons of plastic.

The value of x comes out to be 9.

Here, we are given that m∠7 = 107 and m∠4 = (8x+1)

From the figure given below, we can see that angle 7 and angle 6 are vertically opposite angles. Thus-

angle 7 = angle 6

measure of angle 6 = 107°

Now, angle 6 and angle 4 are opposite interior angles and the sum of opposite interior angles is equal to 180. Thus-

m∠4 + m∠6 = 180

8x + 1 + 107 = 180

8x + 108 = 180

8x = 180 - 108

8x = 72

Your question was incomplete. Check for the missing figure below.

Total of 10 and $ total of $0.85. The place value denotes a word, whereas the total value denotes a figure. In mathematics, ten numbers are known as symbols or digits.

The sum of the digit and its place value is the total value. Example 1: In the number 58439, what is the place value of digit 4? As a result, digit 4's place value is Hundreds. Market capitalization is the value of a company as determined by the stock market. It is defined as the sum of all outstanding shares' market values. Multiply the number of outstanding shares by the current market value of one share to calculate a company's market cap.

·        Since we have 2 unknowns, we need to set up a System of 2 Equations.

·        A System of 2 Equations helps us solve a situation with 2 Unknowns.

Let's set up our 2 equations for # and $.

·        For the # equation:

Let n = # of nickels

Let d = # of dimes

So, n + d = 10

·        For the $ equation, we have to assign a "value" to each of the coins:

A nickel is worth 5 cents or $0.05

A dime is worth 10 cents or $0.10

·        They told us we have 5 cents, a specific # of times + 10 cents, a certain # of times, that = $0.85

So,   $0.05n + $0.10d  

        = $0.85

To solve this, we have to have just 1 unknown, meaning just 1 variable.

· We represent one of the variables in terms of the other. But, which one?

·        Well, since they are asking for # of dimes, let's define a nickel in the duration of a dime.

·        Let's apply this in the simpler # equation:

So, n + d = 10

becomes n = 10 - d

·        So now, in our $ equation, we can just replace "n" with "10 - d", and then solve for d, which is the # of dimes!

$0.05n + $0.10d = $0.85

$0.05(10-d) + $0.10d = $0.85

$0.5 - $0.05d + $0.10d = $0.85

$0.50 + $0.05d = $0.85

$0.05d = $0.35

d = 7

Check this with the # equation:

n + d = 10

n + 7 = 10

n = 3

Does that make sense? Let's see:

3 nickels + 7 dimes = $0.85 ?

3($0.05) + 7($0.10) = $0.85

$0.15 + $0.70 = $0.85

$0.85 = $0.85

We can see that function g(x) is a translation of one unit to the left and 3 units downwards of f(x), thus, the correct options are:

C and E.

Here we have the two functions:

f(x)

g(x) = 4^(x + 1) - 3

And we know that g(x) is a translation of f(x)

Remember that the translations works as follows:

Vertical translation of N units:

g(x) = f(x) + N

If N > 0, the translation is upwards.

If N < 0, the translation is downwards.

Horizontall translation of N units:

g(x) = f(x) + N

If N > 0, the translation is to the left

If N < 0, the translation is to the right.

In this case, we can write g(x) as:

g(x) = f(x + 1) - 3 = 4^(x + 1) - 3

So we will have a translation of one unit to the left and 3 units downwards.

The answer given by Mia is not reasonable cause, when we sum up the data given by her we will conclude that the expression should be like (12*36) + (24*84) = 1800.

Step-by-step explanation:

Mia has 12 boxes of chocolate chip cookies and 24 boxes of sugar cookies.

Each box of chocolate chip cookies has 36 cookies.

Each box of sugar cookies has 84 cookies.

So, the total number of chocolate chips cookies will be = 12 * 36 ----(i)

And the total number of sugar cookies will be = 24 * 84 -----(ii)

As Mia says she has about 1,800 cookies in all.

So, we can write (i) and (ii) combined as,

(12*36) + (24*84) = 1800

The answer given by Mia is not reasonable cause, when we sum up the data given by her we will conclude that the expression should be like (12*36) + (24*84) = 1800.

Explanation: No, her answer is not reasonable.

Step by Step solution:

According to the given information, Mia has 12 boxes of chocolate chip cookies and 24 boxes of sugar cookies.

Now, each box of chocolate chip cookies has 36 cookies which means she has (36 × 12) = 432 chocolate chip cookies in total, using the unitary method.

Also, each box of sugar cookies has 84 cookies which means she has (84 × 24) = 1008 sugar cookies in total, using the unitary method.

Mia will then have with her in total of [(36 × 12) + (84 × 24)] = 1440 cookies.

It is an incorrect fact that Mia says that she has about 1800 cookies in total.

Hence, Mia has 1440 cookies in total.
