Answer:

D = 3 cm

Step-by-step explanation:

Given that,

The circumference of a circle is 9.45cm.

We need to find the length of the diameter.

The formula for the circumference of a circle is given by :

[tex]C=2\pi r[/tex]

We know that, Diameter = 2r

So,

[tex]C=D\pi\\\\D=\dfrac{C}{\pi}\\\\D=\dfrac{9.45}{\pi}\\\\D=3\ cm[/tex]

So, the length of diameter is equal to 3 cm.

Answer:

1/8 square unit.

Step-by-step explanation:

Remark

The piece of information that is missing is     is the middle line parallel to 2 of the sides. You have to assume it is, otherwise the question is impossible to do.

Givens

The height of the red triangle is 1/2 the top or bottom white triangle. That's because the diagonals and the horizontal line all meet in the middle.

The base of the red triangle is equal to 1/2 the length of the base.

Formula

Area red = 1/2 b * h

Solution

b = 1/2

h = 1/2

Area = 1/2 * 1/2 * 1/2

Area = 1/8

Answer: [tex]33,007.9\ ft[/tex]

Step-by-step explanation:

Given

The plane is cruising at an altitude of [tex]h=10,200\ ft[/tex]

The angle of depression is [tex]\theta=18^{\circ}[/tex]

Suppose the distance of the plane to the runway is x

from figure

[tex]\Rightarrow \sin 18^{\circ}=\dfrac{h}{x}\\\\\Rightarrow \sin 18^{\circ}=\dfrac{10,200}{x}\\\\\Rightarrow x=33,007.9\ ft[/tex]

Answer:

equation: y=-2x+2

a=-3

b=-8

Step-by-step explanation:

we need to find the equation of the line containing the point (3,-4) and has the slope (m) of -2

slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

we can plug what we know into the equation:

y=-2x+b

we need to find b though

since the point will pass through the point (3,-4) we can subsitute it into the equation to find b

-4=-2(3)+b

-4=-6+b

2=b

the y intercept is 2

so the equation is y=-2x+2

the line also contains the points (a,8) and (5,b)

first, let's find a

a is the x value of the point

we know the value of y (8)

substitute y as 8 and solve for x

8=-2x+2

subtract

6=-2x

-3=x=a

so a is -3

now find b

b is the y value of the point

we know the x value (5)

substitute x as 5 and solve for y

y=-2(5)+2

y=-10+2

y=-8=b

so b is -8

hope this helps!

B.) 205.3³

Step-by-step explanation:

                          Volume = (length·width·height) divided by 3

                                                            ⬇

                                                    V = (lwh)/3

                                                            ⬇

                                        V = (11·7·8)/3 ≈ 205.33333

Answer:

2 = 4/2

Step-by-step explanation:

Well the one for the 2 wholes, Since 2 wholes equal 4/2

because 4/2 simplified is 2 whole it I believe would be 4/2

Answer:4/2,5/2

Step-by-step explanation:

I believe that 4,2 because it's going in order and 4/2= 2 which is shown below. And 5,2 because 5/2=2.5 which is half of 2 and 3.

Answer:

if Y=-3 and 4y is the equation then the answer is -27

Answer:

4y=-12

4+y=1

Step-by-step explanation:

when y=-3

then you substitute the value of y into the questions

4(-3)=

4×-3

=-12

4+y

4+(-3)

we know that plus(+) multiplied by(×) minus(-) is equal to(=) minus(-)

so therefore,

4-3

=1

Answer:

129.3 in²

Step-by-step explanation:

The shaded segment is calculated as

area of sector ABC - area of triangle ABC

area of sector = area of circle × fraction of circle

A = πr² × [tex]\frac{60}{360}[/tex]

   = π × 18² × [tex]\frac{1}{6}[/tex]

   = 324π × [tex]\frac{1}{6}[/tex] = 54π in²

area of Δ ABC = [tex]\frac{1}{2}[/tex] × 18 × 18 × sin60°  ≈ 40.30 in²

Then

shaded area = 54π - 40.30 ≈ 129.3 in² ( to the nearest tenth )

Answer:

Rs 100x² + 150x - 100

Step-by-step explanation:

Area of the parking space = Length * Width

Area of the space = (2x-1)(x+2)

Expand

Area of the space = 2x² + 4x - x - 2

Area of the space = (2x²+3x - 2) sq. m

Since 1sq.m = Rs 50'

(2x²+3x - 2) sq. m= z

z = 50 (2x²+3x - 2)

z = 100x² + 150x - 100

hence the cost of the parking spsce is Rs.100x² + 150x - 100

Answer:

137,540,000

Step-by-step explanation:

###AAA#

There are 10 digits from 0 to 9.

There are 26 letters from A to Z.

We apply the counting principle. We see the number of possible digits or letters than can be placed in each position, and then we multiply them together.

There are 10 digits for the first position.

###AAA#

10

There are 10 digits for the second position.

###AAA#

10 * 10

There are 10 digits for the third position.

###AAA#

10 * 10 * 10

There are 23 letters for the fourth position.

###AAA#

10 * 10 * 10 * 23

There are 26 letters for the fifth position.

###AAA#

10 * 10 * 10 * 23 * 26

There are 23 letters for the sixth position.

###AAA#

10 * 10 * 10 * 23 * 26 * 23

There are 10 digits for the seventh position.

###AAA#

10 * 10 * 10 * 23 * 26 * 23 * 10

Now we multiply all the numbers together.

10 * 10 * 10 * 23 * 26 * 23 * 10 = 137,540,000
