Answer:

41.63

Step-by-step explanation:

Circumference = 2pi(r)

26.5 / 2 = 13.25 (radius)

2pi(13.25) = 83.25 (circumference of the full circle)

83.25 / 2 = 41.625 or 41.63

Answer:

i think it is C

Step-by-step explanation:

Answer:

When we are given a point P(x, y) centered at origin with a scale factor of k, then the dilated point will be given by P' (kx, ky)

Applying the concept:

Given A(-2, 4) and A'(-0.25, 0.5), which means , and .

Substituting -2 for x in the equation , we get the below equation:

Now we need to find B' and C' by multiplying 0.125 with the x-coordinate and y-coordinate.

-----

x-coordinate of B is -2, y-coordinate of B is 8

x-coordinate of B'

y-coordinate of B'

So

-----

x-coordinate of C is 6 and y-coordinate of C is 4

x-coordinate of C'

y-coordinate of C'

So

Conclusion:

The below are the TRUE statements:

(i) The coordinates of C' are (0.75, 0.5)

(ii) The scale factor is 1/8

(iii) The coordinates of B' are (–0.25, 1).

Answer: easy = 168

Step-by-step explanation:

Answer:

so x = 168

Step-by-step explanation:

[tex]3 - \frac{x}{12} = -11\\-\frac{x}{12} =-14\\-x = -168\\x = 168[/tex]

The temperatures are in 50° Celsius, -60° Celsius and  -40° Celsius when the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit respectively.

Temperature is a measurement of an object or material's warmth or coldness and an expression of thermal energy.

Given, the conversion expression of degrees Fahrenheit to degree Celsius.

The expression is,

F = (9/5)C + 32

For the option 1,

C = 50° Celsius

Then F = 9 x 50/5 + 32

           = 90 +32

           = 122° Fahrenheit

For the option 2,

C = -60° Celsius

Then F =  9 x -60/5 + 32

           = -108 + 32

            = -76° Fahrenheit

For the option 3,

C = F

Then F = 9F / 5 +32

         F - 9F/5 = 32

         -4F / 5 = 32

           F = -160/4

           F = -40° Celsius.

Therefore, the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit when the temperatures are in 50° Celsius, -60° Celsius and  -40° Celsius respectively.

Answer:

i think 5? im not quite sure

Step-by-step explanation:

Yes, n = 2 is the solution of the equation 4n − 3 = −2n + 9.

Given is the equation -

4n − 3 = −2n + 9

We have -

4n − 3 = −2n + 9

For n = 2, we can write -

4 x 2 - 3 = - 2 x 2 + 9

8 - 3 = 9 - 4

5 = 5

So, n = 2 is the solution of the equation 4n − 3 = −2n + 9.

Therefore, yes, n = 2 is the solution of the equation 4n − 3 = −2n + 9.

Answer:

y-intercept: (0,4)

Slope: -1/3

Step-by-step explanation:

y-intercept: (The y-axis is the vertical axis.) this is where the line crosses the y-axis. (This always occurs when x = 0.) From the graph, the purple line crosses the y-axis at 4 therefore: y-intercept = (0,4)

slope:

slope = rise / run

this means slope = y/x

first step is to locate to places along the purple line that cross the grid boxes neatly. this occurs at (-3,5), (0,4), and (3,3).

Taking any two of the three intersections listed above one can find the slope of a line. To demonstrate solving, we will solve for slope three way using the same method, different points:

___________________________________

Option 1: (-3,5), (0,4)

[With ordered pairs, x is always listed first followed by y]

slope between two points = change in y / change in x

so slope = (5 - 4) / (-3 - 0)

slope = 1/-3

slope = -1/3

___________________________________

Option 2: (0,4), (3,3)

[With ordered pairs, x is always listed first followed by y]

slope between two points = change in y / change in x

so slope = (4 - 3) / (0 - 3)

slope = 1/- 3

slope = -1/3

___________________________________

Option 3: (-3,5), (3,3)

[With ordered pairs, x is always listed first followed by y]slope between two points = change in y / change in x

so slope = (5 - 3) / (-3 - 3)

slope = 2/- 6

reduce to:

slope = 1/- 3

slope = -1/3

___________________________________

NOTES: a tip to check if a slope will be positive or negative can be found by just looking at the graph. If the lower part of the line is to the left, the slope will be positive. If the lower part of the line is to the right (as in question), the slope will be negative.
