Answer:

3/32

Step-by-step explanation:

the reason it’s 3/32 is because you have to divide 3/4 divide by 8. So that means 3/4x1/8 and that gives you 3/32. I hope that helped you!

Answer:

15%

Step-by-step explanation:

11.1 / 73 = 0.152054~

That answer rounded to the nearest hundreth is 0.15 so it'd be 15%

Answer:

A. A rotation of 72º around the center, point D.

C. A reflection across line b through one vertex, the center d.

E. A reflection across line c, and the midpoint of the opposite side

Step-by-step explanation:

From Euclidean Geometry we get that sum of internal angles inside a polygon equals 360º and there is the following relationship in regular polygons:

[tex]\theta = \frac{360^{\circ}}{n}[/tex] (Eq. 1)

Where:

[tex]\theta[/tex] - Internal angle, measured in sexagesimal degrees.

[tex]n[/tex] - Number of sides, measured in centimeters.

If we know that [tex]n = 5[/tex], then internal angle of regular pentagon is:

[tex]\theta = \frac{360^{\circ}}{5}[/tex]

[tex]\theta = 72^{\circ}[/tex]

In consequence, rotating the regular pentagon 72º around the pentagon carries the figure onto itself due to angular symmetry. (Correct answer: A)

By adding any line passing the center of the regular pentagon (i.e. line cc', line bb'), which is collinear to any vertex and any point of the figure, we guarantee conditions of length symmetry so that reflection carries the figure onto itself. (Correct answers: C, E)

Answer:84

Step-by-step explanation:

Since each trinagle's interior angles which is the angles in side the triangle always add up to 180 you could add the 2 given and then subtract by 180 so 48+48 which equals 96 then 180-96 which will give you 84 as x

Answer

48+48+x=180    x=84

Step-by-step explanation:

The sum of the 3 interior angles of a triangle is always the sum of 180 degrees.  

In short, this means that all three angles have to equal up to 180 degrees

48+48=96

180-96=84  x=84

To check your answer add

48+48+84 should equal 180. It does

Hope this helps

Answer:

[tex]\displaystyle \frac{199}{18}[/tex]

Step-by-step explanation:

Fraction Operations

Before attempting to operate with the given fractions, we need to express all of them in the form a/b, because the last 2 fractions are in mixed form.

[tex]\displaystyle 8\frac{3}{7}=8+\frac{3}{7}=\frac{8*7+3}{7}=\frac{59}{7}[/tex]

[tex]\displaystyle 5\frac{11}{14}=5+\frac{11}{14}=\frac{5*14+11}{14}=\frac{81}{14}[/tex]

Now for the sum of the last two fractions:

[tex]\displaystyle \frac{59}{7}+\frac{81}{14}[/tex]

Make both denominators equal by multiplying by 2 both parts of the first fraction:

[tex]\displaystyle \frac{59}{7}+\frac{81}{14}=\frac{118}{14}+\frac{81}{14}[/tex]

[tex]\displaystyle =\frac{118+81}{14}=\frac{199}{14}[/tex]

Now multiply by 7/9:

[tex]\displaystyle \frac{199}{14}*\frac{7}{9}=\frac{199}{18}[/tex]

Answer:

$143,000

Step-by-step explanation:

Newman consulting company maintains its record on its cash basis

The first step is to calculate the revenue

$420,000+($60,000-$52,000)

= $420,000+$8,000

= $428,000

The expenses can be can be calculated as follows

Utilities expenses = $35,000-($6,000-$4,000)

= $35,000-$2,000

= $33,000

Advertising expenses= $12,000

Salaries expenses= $240,000

Total expenses= $240,000+$12,000+$33,000

= $285,000

Therefore the accural net income for the year can be calculated as follows

= revenue - expenses

= $428,000-$285,000

= $143,000

Hence the accrual net income for the year is $143,000

Answer:

Option C: since a false statement resulted, it means x = 2 is not a zero.

Step-by-step explanation:

We are told that She is checking the zeros of her quadratic function.

Now the zeros of a quadratic function f(x) are values of that make f(x) = 0. In order words they are basically the roots of the function or the x-intercept.

Now, she has tried x = 2 into her quadratic equation and it didn't yield zero.

Since it yielded -3 and not 0, it means 2 is not a zero of the quadratic function.

Answer:

a

[tex]A_w  =  1.667  \ hour [/tex]

b

 [tex]b  =  0.667 \  hour  [/tex]

Step-by-step explanation:

From the question we are told that

   The mean number of ticket per hour is  [tex]\mu  =  12 \  tickets[/tex]

   The  mean number of customers arrive to purchase tickets each hour is [tex]\lambda  =  8 \  customers[/tex]

    Generally the average time the ticket buyer must wait is mathematically represented as

      [tex]A_w  =  \frac{\lambda }{ \mu [\mu -\lambda]}[/tex]

=>    [tex]A_w  =  \frac{8 }{ 12 [12-8]}[/tex]

=>     [tex]A_w  =  1.667  \ hour [/tex]

Generally the portion of time is the ticket seller busy is mathematically represented as

     [tex]b  =  \frac{\lambda}{ \mu}[/tex]

=>    [tex]b  =  \frac{8}{ 12} [/tex]

=>    [tex]b  =  0.667 \  hour  [/tex]

Answer:

A, 80

Step-by-step explanation:

An equilateral triangle has three equal sides. Let's try to first find the actual value of each side of the triangle!

96 inches is the perimeter of the triangle. The triangle has three equal sides. We can find the length of each side by dividing 96 inches by 3!

96 / 3 = 31 inches

The length of each side in the equilateral triangle is 31 inches.

We know that the length of each side is 2x + 6, and we previously found that the length of each side in the equilateral triangle is 31 inches. We are trying to find x, so we can create an equation and isolate x!

31 = 2x + 6

-6    -6

25 = 2x

÷2     ÷2

12.5 = x

Yay, we just found x! That's the answer! Feel free to ask any questions if you need help. I'm not here to judge; I'm here to help. :)

Answer:

Simpson's Paradox

Step-by-step explanation:

Answer:

[tex]f(g(2))=10[/tex]

Step-by-step explanation:

We have the two functions: [tex]f(x)=3x-5[/tex] and [tex]g(x)=2+\frac{6}{x}[/tex].

We want to find [tex]f(g(2))[/tex].

So, let's use the second function to find [tex]g(2)[/tex] first:

[tex]g(2)=2+\frac{6}{2}[/tex]

Divide:

[tex]g(2)=2+3[/tex]

Add:

[tex]g(2)=5[/tex]

Therefore, our expression is the same to [tex]f(g(2))=f(5)[/tex].

Now, we can substitute 5 for f(x). This yields:

[tex]f(5)=3(5)-5[/tex]

Multiply:

[tex]f(5)=15-5[/tex]

Subtract:

[tex]f(5)=10[/tex]

So:

[tex]f(g(2))=10[/tex]

And we're done!

Answer:

1999

Step-by-step explanation:

The equation which represents the given situation is P=180t+620.

Given that, the population at time t=3 is 1160 and at time t=5 is 1520, where t is the number of years after 1990​.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Now, the standard form of the population is increasing linearly is P = mt + b.

Where m is the slope = (y2-y1)/(x2-x1)=(1520-1160)/(5-3)

=360/2

=180

So, 1160=180 × 3 + b

⇒ 1160=540 × 3 + b

⇒ b=620

Then, the equation is P=180t+620

Therefore, the equation which represents the given situation is P(t)=180t+620.
