Answer:

  779.4 square units

Step-by-step explanation:

You seem to have several problems of this type, so we'll derive a formula for the area of an n-gon of radius r.

One central triangle will have a central angle of α = 360°/n. For example, a hexagon has a central angle of α = 360°/6 = 60°. The area of that central triangle is given by the formula ...

  A = (1/2)r²sin(α)

Since there are n such triangles, the area of the n-gon is ...

  A = (n/2)r²sin(360°/n)

__

For a hexagon (n=6) with radius 10√3, the area is ...

  A = (6/2)(10√3)²sin(360°/6) = 450√3 ≈ 779.4 . . . . square units

Answer: 127.5km

Step-by-step explanation:

We are informed that Ron cycled 510km last week and that he was under the rain for the 25percent of his journey.

The distance travelled did under the rain will be gotten by multiplying 25% by 510km. This will be:

= 25% × 510

= 0.25 × 510

= 127.5km

He was in the rain for 127.5km

Answer:

29.3

Step-by-step explanation:

to find average you find the sum of all the minutes she practiced and divide it by the total amount of day she practiced.

first we have to find the sum of the minutes she practiced:

20+30+40+38+25+22+39+22+26+31

this equation is equal to 293 minutes she practiced in total. Now we have to divide this by the total amount of days she practiced whice according to the data is 10! So:

293/10 =29.3

Answer:

(-1,3)

Step-by-step explanation:

3x + 6y  =  15

6x + 6y =  12                   Subtract

-3x        = 3                     Divide by 3

-x = 1                               multiply by - 1

x =  - 1

3x + 6y = 15

3(-1) + 6y = 15

-3 + 6y = 15             Add 3 to both sides

-3+3 + 6y = 15 + 3

6y = 18                    Divide by 6

y = 18/6

y = 3

Answer:

1 - p

Step-by-step explanation:

Given

[tex]Winning = p[/tex]

Required

Determine the probability of not winning

To do this, we apply the complement rule which is:

[tex]Not\ Winning = 1 - Winning[/tex]

Substitute p for Winning

[tex]Not\ Winning = 1 - p[/tex]

Hence, the expression that June does not win is: 1 - p

Answer:

y-9=-5/2(x+6)

Step-by-step explanation:

y-y1=m(x-x1)

y-9=-5/2(x-(-6))

y-9=-5/2(x+6)

An equation in point-slope form for this line would be y-9=-5/2(x+6).

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

Which is the required equation of a line in a point-slope form.

Thus,

y-y1= m(x-x1)

A line passes through the point (-6,9) and has a slope of -5/2 So,

y-9=-5/2(x-(-6))

y-9=-5/2(x+6)

Hence, an equation in point-slope form for this line would be y-9=-5/2(x+6).

The answer is -5

Step-by-step explanation:

First, let's understand about what are rational number and Integer.

Both rational and Integer are part or rather say subset of Real Number. Real Number can be broken into these categories:

I will not talk about Irrational since It is a bit off-topic for the question.

Rational can be broken into:

Integer is a subset of Rational Number and Real Number. But what is really Integer?

Integer is a whole number or any numbers that don't have decimal, fraction. Integer can be ...,-4,-3,-2,-1,0,1,2,3,4,...

The three dot symbol refers to being endless or countable infinity.

Now that you see Integer cannot be fraction, decimal.

Therefore, the answer is -5

Answer: B) -5

Step-by-step explanation:

An integer is like a whole number, but it also includes negative numbers (e.g. -300, -5, 0, 5, 6, 100).

You can write a rational number as a ratio of two numbers (e.g. 7/1, 1/3, -2/3, -4/7).

None of the answer choices given are integers, except -5. It is also a rational number, since it can be written as -5/1.

Answer:

145.8cm squared

Step by step:

16.2 divided by 3 = 5.4cm

In the second line where 2 bricks are horizontal and 2 are vertical:

2x + 3y = 16.2

3y = 16.2 - 2 x 5.4

y = 1/3 x 5.4

y = 1.8cm

Hence, height and length of each triangle is 1.8cm and 5.4cm

Complete length = 16.2 cm

Complete height = 2y + x = 2 x 1.8 + 3.4

                            = 9 cm

Area overall = 16.2 x 9 = 145.8cm squared

Answer:

Father's age = 48

Daughter's age = 24

Step-by-step explanation:

Let x be father's age and y be daughter's age.

1st equation:

x = 2y

2nd equation:

(x - 16) = 4(y - 16)

Replacing value of x from 1st equation,

(2y - 16) = 4(y - 16)

2y - 16 = 4y - 64

4y - 2y = 64 - 16

2y = 48

y = 48/2

y = 24

And,

x = 2y

x = 2 x 24

x = 48

8x - x = 64 - 16

7x = 48

Answer:

3x^2 - 7x +4

Step-by-step explanation:

see step on the file joint

The quotient of 9x³ - 21x² + 12x divided by 3x is  3x² - 7x + 4.

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given, A cubic polynomial 9x³ - 21x² + 12x and being divided by 3x.

So, (9x³ - 21x² + 12x)/(3x).

= 9x³/3x - 21x²/3x + 12x/3x.

= 3x² - 7x + 4.

So, The quotient when 9x³ - 21x² + 12x and being divided by 3x is

3x² - 7x + 4.
