What's The Value Of X

Answers

Answer 1

Answer:

the answer to this will be 15

Answer 2

Answer:

x=15

Step-by-step explanation:

The angles in a triangle always add up to 180°

3x+7x+2x=180

12x=180  (combine like terms)

[tex]\frac{12x}{12}[/tex]=[tex]\frac{180}{12}[/tex]   (Divide both sides by 12)

x=15

Answer:

Step-by-step explanation:

Inscribed Angle = 1/2 Intercepted Arc

< MQP = 1/2 ( 86)

< MQP = 43

Answer:

43°

Step-by-step explanation:

The measure of an inscribed angle is half the measure of the arc it subtends.

m<Q = (1/2)m(arc)MP

m<Q = 1/2 * 86°

m<Q = 43°

1.) Find the slope of the line represented by the table
2.) Find the y-intercept


need help asap

Answers

The slope of the line is 3 and the y intercept is 1

Answer:

3, 1

Step-by-step explanation:

Slope is rise/run, with the rise being the y increase, and x being the x increase.

Since the run represented is 3, and the rise is 9:

9/3 = 3

The y-intercept is the value of f(x) (which is y) when x = 0

since the equation of the line is:

f(x) = 3x + b

we need to go down 3 units of x since x = 0

3 x 3 = 9

10 - 9 = 1

b = 1

The y-intercept is 1.

Which measure of central tendency is the most appropriate to use to compare the most common women's running shoe colour purchased at a shoe store with the most common women's sandal colour purchased?

Answers

Answer:

The mode of the data sets

Step-by-step explanation:

The measure of central tendency is a value that aims to give the description of a data set by providing a pointer to the central position of the data set

The item under comparison = The most common women running shoe color and the most common women sandal color

The characteristics of the items under comparison = Color (nominal characteristic)

Therefore, the measure of central tendency will aim to show the frequency with which particular colors are worn, which is represented by the mode of the data set

Elena drops her pencil into her cup and notices that it just fits diagonally. The pencil is 17 cm long and the cup is 15 cm tall. The diameter of the cup is 8 cm.

What is the Pythagoras theorem?

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

Elena drops her pencil into her cup and notices that it just fits diagonally. The pencil is 17 cm long and the cup is 15 cm tall.

Consider the pencil and cup just make a right angle triangle. If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2 \\\\|17|^2 = |15|^2 + |BC|^2 \\\\289 = 225 + |BC|^2 \\\\ |BC|^2 = 289 - 225\\\\ |BC|^2 = 64\\\\ |BC|^2 = \sqrt{64} \\\\BC = 8[/tex]

Halla el área de un triángulo equilátero de 54 cm de perímetros

Answers

Answer:

Area of equilateral triangle = 81√3 cm²

Step-by-step explanation:

Given:

Perimeter of an equilateral triangle = 54 cm

Find:

Area of equilateral triangle

Computation:

Perimeter of an equilateral triangle = 3 x Side

54 = 3 x Side

Side of equilateral triangle = 54 / 3

Side of equilateral triangle = 18 cm

Area of equilateral triangle = [√3/4]side²

Area of equilateral triangle = [√3/4][18]²

Area of equilateral triangle = [√3/4][324]

Area of equilateral triangle = [√3][81]

Area of equilateral triangle = 81√3 cm²

Firstly this shape is an triangle and a triangle has 3 sides/ angles and all angles sum up to 180 degrees...

E = 90 degrees

This explains that it is an hypotenuse triangle so...

answer:

= 39x39 = 1521

= 89x89 = 7921

= 1521 + 7921 = 9442

= square root of 9442 = 97.169954204 rounded off to 97.2

m∠N = 32°

NQ = 106°

When finding inscribed angles like ∠N with the intercepted arc, the equation is ∠N=1/2MP. (Inscribed angles are always half the degree of the arc length.) Plug in the corresponding value to get ∠N=1/2(64) to get 32°. When finding the angle of the intercepted arc with inscribed angles like NQ, the equation is NQ=2(∠P). Plug in the corresponding value to get 2(53) to get 106°.

The ratio of health club members who use trainers to those who do not
is 2:5. There are 342 members who use trainers. How many members
does the club have?

Answers

Answer:

Step-by-step explanation:

The anwser is 479 - 2:5 as a decimal is .4 , 342 x .4 is 126.8

342+126.8 = 178.8

round it and get 479

By using given ratio, Members does the club have are 1197.

What is ratio?

"A ratio can be defined as the relationship or comparison between two numbers of the same unit to check how bigger is one number than the other one."

We have,

Ratio of health club members who use trainers and who do not  is 2:5.

Members who use trainers = 342

Members who does not use trainers

= [tex]\frac{342}{2}[/tex]×[tex]5[/tex]

= 171 × 5

= 855

Total members

= 855 + 342

= 1197

what is the value of x and y *don't simplify into decimal*

Answers

Answer:

x = 20

y = 20√2  

Step-by-step explanation:

This is a 45 - 45 - 90° special right triangle

In a 45 - 45 - 90° triangle the legs are congruent and the hypotenuse = leg * √2

If one leg = 20 then the other leg also = 20

Thus, x = 20

If leg = 20

Then hypotenuse = 20 * √2 or 20√2

Thus, y = 20√2
