Answer:

1/3 of twelve is 4 so four must be the answer

Step-by-step explanation:

The seattle great wheel is an illustration of sectors, arcs, circumference and area of circles

The diameter is given as:

d = 175 feet

The circumference (C) is calculated as:

C = πd

This gives

C = 3.14 * 175

C = 549.5 feet

Hence, the circumference of the wheel is 549.5 feet

This is calculated as:

A = π(d/2)^2

This gives

A = 3.14 * (175/2)^2

A = 24040.625

Hence, the area of the wheel is 24040.625 square feet

This is calculated as:

θ = 360/n

Where n is the number of capsules

So, we have:

θ = 360/42

This gives

θ = 8.57 degrees

Hence, the central angle of the wheel in degrees is 8.57

This is calculated as:

Radians = Degrees × π/180

So, we have:

θ = 360/42 * π/180

This gives

θ = π/21 rad

Hence, the central angle of the wheel in radians is π/21 rad

This is calculated as:

L = θ * d/2

So, we have:

L = π/21 * 175/2

This gives

L = 175π/42

Hence, the arc length between two capsules is 175π/42

This is calculated as:

A = 0.5 * (d/2)^2 * θ

So, we have:

A = 0.5 * (175/2)^2 * π/21

This gives

A = 168π

Hence, the area of sector between two capsules is 168π

Answer:

70

Step-by-step explanation:

Same side interior angles of parallel lines cut by a transversal are supplementary, so their measures have a sum of 180°.

2x - 5 + 45 = 180

2x + 40 = 180

2x = 140

x = 70

We need the square root of H to equal 7, so we can just square 7 to get the answer. So 7x7 = 49.

Answer:

3(3r - 4)(3r + 4)

Step-by-step explanation:

I can't see the writing very clearly.

This is the correct solution:

27r^2 - 48                   Divide through by 3:

= 3(9r^2 - 16)               9r^2- 16 is the difference of 2 squares so:

= 3(3r - 4)(3r + 4)

Answer: x = 56

Step-by-step explanation:

The two angles 'z' and 124 add up to form a straight line. The angle of a straight line is 180 degrees. Therefore, we can say that:

[tex]z+124=180[/tex]

Subtract 124 on both sides to isolate the angle 'z' to get:

[tex]z=56[/tex]

Answer:

z=56 degrees

Step-by-step explanation:

in total the line will equal 180 so just do 180-124 and you get 56.

Answer:

Yes

Step-by-step explanation:

There are two green regions and two red regions which makes four regions in total. If there is an equal probability to land on each region, it means that the probability to land on a green region is 2/4 because there are two green regions out of the four total regions. You could also simplify it to 1/2.

Check:

L.H.S = R.H.S  Thus x = 3 confirmed

Answer:

x = 3

Step-by-step explanation:

We are trying to move all terms that have x on one side of the equal sign and terms that  do not have an x on the other side of equal sign.

terms with x = terms without x

            4x -3 = 3x , subtract 3x from both side of the equation

      4x -3x -3 = 3x -3x

      4x -3x -3 = 0 , add 3 to both sides of the equation

4x -3x -3 + 3 = 0 + 3

          4x -3x = 3 , combine like terms

                 x = 3

Or

We can think we move each term where we want it, yet keep in mind that once we cross the equal sign we change the sign of the term if addition or subtraction are the only operations involved.

4x -3 = 3x , 3x is positive so will become negative on the other side of the equal sign and -3 is negative so will become positive on the other side.

4x -3x = 3

        x = 3

Answer:

y = -x + 7

Step-by-step explanation:

Hi there!

We are given the following points:
(5,2) and (10,-3)

We want to find the equation of the line that passes through these 2 points

There are 3 ways to write the equation of the line, yet the most common way is slope-intercept form, which is y=mx+b (m is the slope and b is the y intercept).

First, let's find the slope of the line.

The slope can be calculated from 2 points using the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We have everything we need to find the slope, but let's label the values of the points to avoid confusion and mistakes.

[tex]x_1=5\\y_1=2\\x_2=10\\y_2=-3[/tex]

Now substitute these values into the formula to find the slope

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{-3-2}{10-5}[/tex]

Simplify

m=[tex]\frac{-5}{5}[/tex]

Divide

m=-1

The slope of the line is -1

We can substitute this value as m in y=mx+b.

Here's the equation of our line so far:

y=-x+b

Now we need to find b

As the equation passes through the points (5,2) and (10,-3), we can use either point to find the value of b

Taking (5,2) for example:

Substitute 5 as x and 2 as y

2=-5+b

Add 5 to both sides

7=b

Substitute 7 as b in the equation

y = -x + 7

Hope this helps!
