William travels only on Saturdays and Sundays and has flown 1,020 miles this month. Jason travels every weekday and has flown 1,
2 answers:
Answer: William travels more miles per day this month.
Step-by-step explanation:
Since we have given that
On Saturdays and Sundays , number of miles travel by William this month = 1,020 miles
As we know that
Number of Saturdays and Sundays in a month = 8
So, number of miles per day they travel is given by
On weekdays, number of miles travel by Jason this month = 1,200 miles
As we know that
Number of weekdays in a month = 30-8 =22
So, Number of miles per day they travel is given by
Hence, William travels more miles per day this month.

Answer:
OK, lets start by drawing a basic graph (the first one) so we can visualize.
We already know that the y coordinate of the circle's center is .
We know that the circle is tangent to the axis at
That means the x coordinate of the center has to be , as the tangent is a point on the edge of the circle that touches a line at exactly one point.
The radius is the distance from the center of the circle to its edge. We know the center's location now, it is and a point on the edge of the circle (the tangent point) which is
. so the distance between the points is 4 which is the radius (you can use the distance formula, but it's quite oblivious.)
We can imagine the circle should look like this (the second one):
Now we can piece together an equation
The equation of a circle is where
is the center and
is the radius. When we put the numbers in: we get
which can be simplified into
which is the answer.
