Answers

Hey there!

The answer to your question is x = 7

We can solve this by simplifying both sides of the equation:

2x - 6 = 8x - 48

Then, add 48 to both sides:

2x + 42 = 8x

Then, subtract 2x from both sides:

42 = 6x

Lastly, divide both sides by 6:

7 = x

A 13 sided figure has how many
total degrees in its interior angles?

Answers

9514 1404 393

Answer:

  1980°

Step-by-step explanation:

The formula for the sum of interior angles of an n-gon is ...

  angle sum = 180°(n -2)

For n=13, the angle sum is ...

  angle sum = 180°(13 -2) = 180°×11

  angle sum = 1980°

At Martin Luther King Jr. High School 7 out of 9 students voted to plant trees at the front of the school. A total of 119 voted to plant the trees. How many students voted?
A. 153
B. 272
C. 128
D. 135​

Answers

Answer and Step-by-step explanation:

To solve, you first divide 7 by 9.

Then, you divide 119 by 7/9.

[tex]\frac{7}{9} = 0.777777777777\\\\\frac{119}{0.77777777777} = 153.\\\\[/tex]

To check your work, divide 119 by 153, and you will get 0.777777777777, which is the same as 7 divided by 9.

So, the answer is A. 153

#teamtrees #WAP (Water And Plant)

Answer:

add x to both sidesdivide both sides by 4add 20 to both sidesdivide both sides by 3

Step-by-step explanation:

Your steps in order would be ...

add x to both sidesdivide both sides by 4add 20 to both sidesdivide both sides by 3

__

Executing these steps, we get ...

  4(3x -20) = 16 . . . . . add x

  3x -20 = 4 . . . . . . . . divide by 4

  3x = 24 . . . . . . . . . . .add 20

  x = 8 . . . . . . . . . . . . . divide by 3, giving the solution

_____

Additional comment

If you were to distribute the 4 first, you would have ...

  12x -80 -x = 16 -x

Now, you can add x and add 80 to get ...

  12x -80 = 16

  12x = 96

Then dividing by 12 gives ...

  x = 8

You will notice that these steps do not match steps available in your list.

(a) The diagram shows a circle, centre 0. AB and CD are chord.
Given that OM = 8 cm, NT = 3 cm, AB = 30 cm.

(1) Calculate the radius
(2) Calculate the length of CD​

Answers

Answer:

1) Radius = 17 cm

2). CD = 19.3 cm

Step-by-step explanation:

1). O is the center of the given circle.

 By joining the center and point A located at the circumference of the circle,

 OA = radius of the circle.

 Length of chord AB = 30 cm

 "Line from the center of a circle to the chord inside the circle is a perpendicular bisector of the chord"

  By the given property, OM equally divides the chord AB.

 AM = MB

 AM = [tex]\frac{1}{2}(AB)[/tex]

 AM = [tex]\frac{10}{2}[/tex] = 5 cm

 By applying Pythagoras theorem in ΔOAM,

 AO² = OM² + AM²

 AO² = 8² + 15²

 AO =  √289

 AO = 17 cm

 Therefore, radius of the circle = 17 cm

2). Since, OT, OC and OA are the radii of the given circle,

  OT = OC = OA = 17 cm

  ON = OT - NT

         = 17 - 3

         = 14 cm

   By applying Pythagoras theorem in ΔOCM,

   OC² = ON² + CN²

   17² = 14² + CN²

   CN = [tex]\sqrt{(17^2-14^2)}[/tex]

         = [tex]\sqrt{93}[/tex]

         = 9.64 cm

     Since, CD = 2(CN)

      CD = 2 × 9.64

             = 19.29 cm

              ≈ 19.3 cm

Step-by-step explanation:

The ratio of areas is the square of the ratio of linear dimensions.

  ar(ΔABC)/ar(ΔDEF) = (AB/DE)² = (1/2)² = 1/4

Then ...

  ar(ΔABC) = (1/4)(100 cm²) = 25 cm² . . . . . multiply by ar(ΔDEF)

The area of ΔABC is 25 cm².

Carmen is buying a fitness tracker that costs $129.95. She has a coupon for 20%. After the coupon is used, 7% tax will be charged. What is the final cost of the fitness tracker with tax?

Answers

9514 1404 393

Answer:

  $111.24

Step-by-step explanation:

The use of a 20% off coupon causes the price to be multiplied by (1 -20%) = 0.80. The addition of 7% tax causes the discounted price to be multiplied by (1 +7%) = 1.07. Multiplying the price by these two factors gives ...

  $129.95 × 0.80 × 1.07 = $111.24

The final cost with tax is $111.24.
