The length from the vertex to the centroid is twice the length from the

centroid to the midpoint of the opposite side.

x is 37Segment [tex]\overline {DG}[/tex] is 22Segment [tex]\overline {GA}[/tex] is 44Segment [tex]\overline {AD}[/tex] is 66

Reasons:

The known parameters are;

The centroid of ΔABC = Point G

Segments [tex]\overline {AD}[/tex], [tex]\overline {BE}[/tex], and [tex]\overline {CF}[/tex] are the medians of ΔABC

Length of line segments [tex]\overline {DG}[/tex] = x - 15

Length of line segments [tex]\overline {GA}[/tex] = x + 7

Required:

The value of x, and lengths of the segments of median [tex]\overline {AD}[/tex]

The median is divided at the centroid of the triangle to ratio 2:1

[tex]Length \ of \ line \ segment \ \overline{GA} = \dfrac{2}{3} \times \overline{AD}[/tex]

Therefore;

[tex]\overline{AD} = \mathbf{\dfrac{3}{2} \times \overline{GA}}[/tex]

[tex]Length \ of \ line \ segment \ \overline{DG} = \mathbf{\dfrac{1}{3} \times \overline{AD}}[/tex]

Therefore;

[tex]\overline{AD} = 3\times \overline{DG}[/tex]

Which gives;

[tex]\dfrac{3}{2} \times \overline{GA} = 3\times \overline{DG}[/tex]

Therefore;

[tex]\dfrac{3}{2} \times (x + 7) = 3\times (x - 15)[/tex]

3·x + 21 = 6·x - 90

21 + 90 = 6·x - 3·x

111 = 3·x

3·x = 111

[tex]x = \dfrac{111}{3} = 37[/tex]

x = 37

[tex]\overline {DG}[/tex] = x - 15

The length of line segment [tex]\overline {DG}[/tex] = 37 - 15 = 22

[tex]\overline {GA}[/tex] = x + 7

Length of line segment [tex]\overline {GA}[/tex] = 37 + 7 = 44

[tex]\overline {AD}[/tex] = [tex]\overline {DG}[/tex] + [tex]\overline {GA}[/tex]

Therefore;

Length of line segment [tex]\overline {AD}[/tex] = 22 + 44 = 66

A tuxedo shop rents its tuxedos for $30 per day. They charge a nonrefundable fee of $ 60 for each tuxedo.
Use the dropdown boxes to create an equation that could be used to determine the total cost, y of renting a tuxedo for x days.

Answers

Given parameters:

Charge per day of Tuxedo = $30 per day

Non-refundable charge = $60 for each tuxedo

Unknown:

Equation to determine total cost = ?

Solution:

  Represent;

 Total cost  = y

 Number of days = x

Now;

   Total cost =  Non refundable charge + charge per day

          y  = $60 + $30x

The equation is;

A new concert venue just opened in downtown Augusta and they are in the process of deciding how many tickets they can sell for each show. The venue has three levels, two general admission that only have standing room, and one level with 240 seats. The first level of standing room is a square with one side measuring 80'. The second level, also standing room, is a rectangle measuring 120' by 30' ft. The third level has 240 seats. The venue thinks each person will occupy 2.5 square feet. How many tickets should they sell?

Answers

Answer:

4,240 tickets

Step-by-step explanation:

The first level of standing room is a square with one side measuring 80'.

Area of the first level = length^2

= 80^2

= 6,400 square ft

The second level, also standing room, is a rectangle measuring 120' by 30' ft.

Area of the second level = length × width

= 120 × 30

= 3,600 square ft

Total area of the standing rooms = (6,400 + 3,600) square ft

= 10,000 square ft

Each person in the standing room will occupy 2.5 square ft

Number of Persons that will occupy the standing room = Total area of the standing rooms / 2.5 square ft

= 10,000 square ft / 2.5 square ft

= 4,000

Therefore the number of Tickets that should be sold

= Number of seats + Number for standing Room

= 240 + 4000

= 4,240 tickets

To find m, we can use the formula y2 - y1 / x2 - x1

x1 = 2

y1 = 50

x2 = 4

y2 = 90

Let's plug these numbers into our formula.

m = 90 - 50 / 4 - 2 = 40/2 = 20

So far our equation looks like: y = 20x + b

Now, let's plug one of the points into our equation.

50 = 20(2) + b

Simplify

50 = 40 + b

Subtract 40 from both sides.

10 = b

The final equation is: y = 20x + 10

Answers

The lengths of pregnancy terms for a particular species of mammal are nearly normally distributed about a mean pregnancy length with a standard deviation of 7 days. About what percentage of births would be expected to occur within 7 days of the mean pregnancy length

Answers

Answer:

68.268%.

Step-by-step explanation:

Let \mu be the mean pregnancy length.

The given standard deviation, [tex]\sigma=7[/tex] days

The z-score:

z=\frac{x-\mu}{\sigma}

where x is any pregnancy length.

The range of x within 7 days of the mean pregnancy length is

[tex]\mu-7<x<\mu+7.[/tex]

z-score for this range is:

[tex]\frac{\mu-7-\mu}{\sigma}<z<\frac{\mu+7-\mu}{\sigma}[/tex]

[tex]\Rightarrow -1<z<1[/tex]

So, the area on the normally distributed curve for the above range of z-score will give the expected percentage of birds to occur within 7 days of the mean pregnancy length.

Now, from the z-score table:

The area from [tex]z = -\infty[/tex] to z=1 is 0.84134

and the area from [tex]z = -\infty[/tex] to z=-1 is 0.15866.

So, the area for -1<z<1

=0.84134 - 0.15866

=0.68268

Hence, the percentage of births would be expected to occur within 7 days of the mean pregnancy length=68.268%.

The cost of the hiking trip is 2/3 of the cost of last years trip this year trip cost $32 write and solve an equation to find the cost of last years trip

Answers

Answer:

(32/2)*3=48

Step-by-step explanation:

In order to find the answer, we must find one third of last year's trip. To do this, we can simply divide the cost of this years trip by two, 32/2=16.

Now if we multiply this this number by 3, 16*3=48, we can see that the total cost of last year's trip was $48.

If we'd like to turn this into one equation, it looks like this: (32/2)*3=48
