Answer: Option A and Option D
Step-by-step explanation:
By definition the general equation of a circle has the following form

Where r is the radius and the point (h, k) is the center of the circle
All points that are on the x axis have the following form:
(h, 0)
Therefore all the circles that have their centers on the x axis will have a value of k = 0.
Identify among the options all those equations that have a value of k = 0
The circles that have their center on the x axis are option A and option D
Let the segment be represented by AB where A(0,0) =
and B(3/4,9/10) =
.
The length of the segment drawn by architect can be calculated using distance formula:
AB =



Similarly, Let the actual end points of segment be AC where A(0,0) =
and C(30,36) =
.
The length of the original segment can be calculated using distance formula:
AC =


.
Thus, the actual length is 40 times the length of the segment drawn by the architect.
Thus, the proportion of the model is 1:40
One movie ticket costs $12.20
you divide 97.60 by 8 which equals 12.20
The y is adding up by 0.5
0.5+ 0.5 =1 +0.5 =1.5 etc....
For every 1 (x), 0.5 gets added
Julie runs 0.18 miles in one minute because 4 divided by 22 and you will get 0.18
