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:

six less than the product six and eight in numerical form= (6*8)-6

and 6*8-6=48-6=42

[tex]2\frac{1}{2}*3\frac{1}{3}\\\\\frac{2*2+1}{2}*3\frac{1}{3}\\\\\frac{4+1}{2}* 3\frac{1}{3}\\\\\frac{5}{2} *3\frac{1}{3}\\\\\frac{5}{2} *\frac{3*3+1}{3}\\\\\frac{5}{2}* \frac{10}{3} \\\\\frac{5*10}{2*3} =\frac{50}{6} \\\\\frac{25}{3} \\\\8\frac{1}{3}[/tex]

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:

A, 80

Step-by-step explanation:

Answer:

j = 21 and n = 14

Step-by-step explanation:

we have the equations:

6j + n/3 = 134

j/3 + n = 31

54j + 3n = 1206

j + 3n = 93

53j = 1113

j = 21

(21)/3 + n = 31

7 + n = 31

n = 14

Answer:

A I think

Step-by-step explanation:

Answer:

the values of angle;

a=61

b=61

c=29

Answer: All of the angles combined are 180 degrees. Since b and its adjacent angle is 90 degrees, you would subtract 90-29, which gives you 61. b=61. You would then use both angle measures to determine the other two. You would need to find two values that add up to 90 degrees for c and a. Angle b+c would be equal to 90 degrees, and angle a and d (I used d to represent the 29 degree angle) would be equal to 90 degrees, equaling a total of 180 degrees. Angle a would be equal to 61, and angle c would be equal to 29. Hope this helps.

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

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!

$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:

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:

john has a 6 out of 10 chance of picking a pencil

Answer:

P=37.5%

Step-by-step explanation:

Frequentist Probability

The probability of an outcome is defined as the frequency of the number of times the outcome occurs relative to the number of times that it could have occurred.

The equation to calculate the probability is:

[tex]\displaystyle P=\frac{f}{n}[/tex]

Where f is the number of favorable cases and n is the total cases.

John has in a cup of his desk:

6 pencils

3 blue+5 black+2 red pens=10 pens

Picking one of the utensils from the cup can be done in 16 different ways. That is the total number of cases n=16

The outcome of taking a pencil can be done in 6 ways. That is the number of favorable cases. f=6.

The probability is:

[tex]\displaystyle P=\frac{6}{16}[/tex]

Simplifying:

[tex]\displaystyle P=\frac{3}{8}[/tex]

Or expressed as a percentage:

P=3/8*100%

P=37.5%

Answer:

1. x = -3/2 y+ 1/2z - 2

2. x = -2/3y + -2/3z + 14/3

3. x = 3z - 13

Step-by-step explanation:

solve for x

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: Its 48in

Love you all. And good luck.

The meters of tape left in the roll will be equal to 1/5 meters.

The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.

They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.

As per the information given in the question,

The total length of Tape = 5 m

Total number of pieces = 6

Length of each piece = 4/5 m

Then, the total length of the pieces will be,

6 × 4/5

= 24/5

Then, the amount of tape left in the roll will be,

= 5 - 24/5

= (25 - 24)/5

= 1/5

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.
