Answer:
$3.00 is the constant
Step-by-step explanation:
let x be the mile driven then
total charge=$3.00+[x($0.30)]
Answer:
30%
Step-by-step explanation:
Total number of people registered for the two days seminar = 1000
90% of those registered attended on the first day
This means (90/100)1000 = 900 people attended the seminar on the first day.
That means 100(1000 -900) registered people did not attend the seminar on the first day
80% of those registered attended on the second day
This means (80/100)1000 = 800 people attended the seminar on the second day.
That means 200 (1000 -800) registered people did not attend the seminar on the second day
The percent of those registered did not attend the seminar on either day = 100 + 200 = 300
= 30%
Total = Group A + Group B - (both + neither)
1000 = 900 + 800 - (B + N)
The two unknown variables (both and neither)

Answer: A. 9</h3>
=====================================================
Explanation:
Draw in the segments AO and OC.
Triangle ABO is congruent to triangle CBO. We can prove this through the use of the HL theorem. HL stands for hypotenuse leg.
Since the triangles are congruent, this means the corresponding pieces AB and BC are the same length.
Then we can say:
AB+BC = AC .... segment addition postulate
AB+AB = AC .... plug in BC = AB
2*AB = AC
2*AB = 18
AB = 18/2 .... divide both sides by 2
AB = 9
In short, the chord AC is bisected by the perpendicular radius drawn in the diagram. So all we do is cut AC = 18 in half to get AB = 9.
