in a triangle two sides of the same length the ratio of each of these sides to the third side is 5:3 if the perimeter of the triangle is 65 in find the length of each side of the triangle.?​

Answers

Answer 1

Answer:

Step-by-step explanation:

Perimeter of a triangle equals side 1 plus side 2 plus side 2

           P = s1 + s2 + s3                 side 1 = side 2 =  x

                                                     x/side 3 = 5 / 3

                                                     x  = (5/3) side 3

                                                     x (3/5)  = side 3

                                                 

                                                     perimeter = 65    slove for x

          65  = x + x + 3x/5

         325  = 5x + 5x + 3x

         325  = 13X

          25   = x    equal side 1 and side 2  

          side 3 = 25(3/5)  = 15

NEED HELP QUICK!!!!! A set of data includes the point (17,3.8) and has the regression equation y=-25x+436. What is the residual for this point

Answers

Given:

The regression equation is:

[tex]y=-25x+436[/tex]

The given point is (17,3.8).

To find:

The residual for the given point.

Solution:

We have,

[tex]y=-25x+436[/tex]

Substituting [tex]x=17[/tex], we get

[tex]y=-25(17)+436[/tex]

[tex]y=-425+436[/tex]

[tex]y=11[/tex]

The predicted value at [tex]x=17[/tex] is 11.

The given point is (17,3.8). It means the observed value at [tex]x=17[/tex] is 3.8.

Formula for residual:

Residual = Observed value - Predicted value

Residual = [tex]3.8-11[/tex]

Residual = [tex]-7.2[/tex]

Therefore, the residual for the given point is -7.2.

Each table represents a proportional relationship.

11.90

Step-by-step explanation:

oh yes sorry I didn't see what you chose lol

Answer:

Yes

Step-by-step explanation:

Rounding two decimal points mean there will be two numbers behind the decimal and since 6 is more than 5 and influences the result of the 9 the answer would be 11.90. It could be 11.9 but having said there is two decimal places there should be a 0 hope this helps!!

Find the value for a.

Answers

Answer:

a = 25

Step-by-step explanation:

The exterior angles of a polygon sum to 360°

Sum the exterior angles and equate to 360

a + a + 40 + 51 + 55 + 54 + 2a + 60 = 360, that is

4a + 260 = 360 ( subtract 260 from both sides )

4a = 100 ( divide both sides by 4 )

a = 25

Find the slope of each line.

Answers

Answer:

C) 1

Step-by-step explanation:

Slope = change in y over change in x

In the graph shown as y goes up 1 x goes up 1

so slope = 1/1 or 1

The slope equation is y=mx+b.

b is where the line crosses on the y axis, also known as the y-intercept.

m is the slope, which you are trying to find.

y and x are the points on the graph.

The slope is 3/3, which can be turned into 1, so the answer is c.

   x degree = 112 degree

 

Step-by-step explanation:

let the intersecting point of two cords be O.

then arc QR = angle QOR

which means ; 68 degree = angle QOR

 Now,

angle QOR + angle POQ = 180 degree ( linear pair )

or,  68 degree + angle POQ = 180 degree

hence, angle POQ = 112 degree,.

Write an equation of the parabola with focus (0, -3) and vertex at the origin. Use z for the independent variable.

Answers

Answer:

z^2 = -12y

or y = -(z^2/12)

Step-by-step explanation:

Answer:

z^2 = -12y

Step-by-step explanation:

Given the vertex at origin;

This is same as (0,0)

The focus (0,-3)

The general form is;

(z-h)^2 = 4p(y-k)

(h,k) is the vertex (0,0); so h = 0 and k = 0

The focus is given as;

(h,k + p)

so ;

k + p = -3

but k =0

so p = -3

Thus, the equation of the parabola is;

(z-0)^2 = 4(-3)(y-0)

z^2 = -12y
