Point Q was rotated by -30° (the center of rotation is indicated).

Answer:

[tex]2^{2}[/tex] + [tex](2\sqrt{3}) ^{2}[/tex] = 4 + 4 * 3 = 16 = [tex]4^{2}[/tex]

Step-by-step explanation:

The Pythagorean Theorem states that the two shorter sides of a right triangle squared and added together will equal the longest side (hypotenuse) of the right triangle squared. The longest side of this right triangle is 4, 4 squared is 16. The two shorter sides of the right triangle are 2 and [tex]2\sqrt{3}[/tex], squared individually would be 4 and 12, and added together they also equal 16. These sides are a valid input for the Pythagorean Theorem, so these three sides are the sides of a right triangle. 2 and [tex]2\sqrt{3}[/tex] being the legs of the right triangle, and 4 being the hypotenuse.

Answer:

Number of moles Aluminium sulfide

1 mole of sulfide contains 150 g

Therefore; 16.2/150  

              = 0.108 moles  

The mole ratio of Al2S3 : Al(OH)3 is 1:2

Therefore; moles of Aluminium hydroxide will be;

 = (0.108 × 2)

 = 0.216 moles  

But, 1 mole of  Al(OH)3 contains 77 g

Therefore, the mass of aluminium hydroxide is

  0.216 moles × 77

=  16.632 g

Answer:

DVD sales have been on the decline for over a decade, but a slew of new streaming services and a shift in how consumers are watching movies and TV shows could be the final death knell for the technology.

The same can be said for Blu-Ray discs.

At its peak, DVD sales reached $16.3 billion and were 64% of the U.S. home video market. That was 2005. These days, DVD sales account for less than 10% of the total market, with total sales hitting $2.2 billion in 2018.

Blu-Ray discs, which have always been slightly more expensive than DVDs, launched in 2006. At most, Blu-Ray sales reached $2.37 billion in 2013, before falling to $1.8 billion in 2018. It’s likely that Blu-Ray sales fractionally impacted the decline of DVD sales, but the fact that DVD sales still outpace Blu-Ray sales shows it’s not the real culprit.

Instead, a combination of the Great Recession, a rise in customers buying on-demand and digital copies of films and the launch of streaming services is what has caused DVD sales to decline more than 86% in the last 13 years.

Answer:

60

Step-by-step explanation:

A percentage is divided by 100 to get it's decimal form. So 400/100 = 4.0

Now you take the value given and multiply it by the percentage in decimal form.

So in this case.

15*4 = 60

Answer:

2 3/6

Step-by-step explanation:

divide 15 by 6 to get 2, and left with a remainder of 3.

Answer:

not similar because the lengths aren't the same.

Answer:

x = -6

Step-by-step explanation:

Simplifying

3(1.5x + 9) = 0

Reorder the terms:

3(9 + 1.5x) = 0

(9 * 3 + 1.5x * 3) = 0

(27 + 4.5x) = 0

Solving

27 + 4.5x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-27' to each side of the equation.

27 + -27 + 4.5x = 0 + -27

Combine like terms: 27 + -27 = 0

0 + 4.5x = 0 + -27

4.5x = 0 + -27

Combine like terms: 0 + -27 = -27

4.5x = -27

Divide each side by '4.5'.

x = -6

Simplifying

x = -6

Step-by-step explanation:

The point of concurrency that always lies on the interior of a triangle is to be considered as the incenter.

Here the incenter refer to the concurrency point of the angle bisectors with respect to all of the interior angle.

Here, the point where three angle bisectors of the angles of the triangle should be met out is called as the incenter.

Also, the incenter should always be lies within the triangle.

Step-by-step explanation:

If x is the white dot on the graph:

From what it looks like, x is right between -35 and -34 x (which is -35.5).

If that is the case then none of the answers are correct since -35.5 is equal or less than x. (the sign looks like this:  "[tex]\leq[/tex]" )

Answer:

100 miles

Step-by-step explanation:

Given :

To work :

speed = 50mph

Let time taken = x

From work :

speed = 40mph

30 minutes = 30/60 = 0.5

Time taken = x + 0.5

Distance from home to work :

Distance = speed * time

To work distance = from work distance

This can be algebraically expressed as :

50 * x = 40(x + 0.5)

50x = 40x + 20

50x - 40x = 20

10x = 20

x = 20/10

x = 2

Hence,

Distance = 50 * 2 = 100

The the distance from home to work = 100 miles

The distance from Michael home to work is 100 miles

Speed is the ratio of the total distance travelled to the total time taken. It is given by:

Speed = distance / time

Let d represent the distance from Michael home to work. Hence:

He took 30 minutes (0.5 hours) longer when driving at 40 mph, hence:

d/50 = (d - 20) / 40

40d = 50d - 1000

10d = 1000

d = 100 miles

The distance from Michael home to work is 100 miles
