Answer:
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).

Step-by-step explanation:
Answer: x=3
Step-by-step explanation:
It would be take upto 999 revolutions.
<em>Let try to solve it,</em>
Let n represent number of revolutions.
We are asked to find the number of revolutions it will take for a car wheel of diameter 30 in. to travel a distance of one mile.
1 mile = 63360 inches.
We will use circumference of circle formula to solve our given problem.
Circumference = pi*d , where, D represents diameter of circle.
Now, we will set the product of n and circumference of circle equal to 63360 inches as:
pi*22*n= 63360
n= 63360*7/ 22*22
n= 443520/444
n= 998.91
Therefore It would be take upto 999 revolutions.
