Answer:
Step-by-step explanation:
Let the number of miles = x
C ost = Base + 0.84x
Cost = 220.71 dollars
Base = 19.95
220.71 = 19.95 + 0.84x Subtract 19.95 from both sides
220,71 - 19.95 = 0.84 x Combine
200.76 = 0.84x Divide by 0,84
200.76/0.84 = x
x = 239 miles.
Remark: The trick to this question is to make sure that total Cost, the Base amount, and cost / mile are all in dollars. Don't mix and match.
X = 89
41 + 50 = 91 which is 89 away from 180
Answer:
second one
Step-by-step explanation:
1 grain = 103g
2kg = 2000g
grains = 2000g/103g = 19.417
Answer:
About 19.417 grains
One leg is horizontal, on the line y=3. Another leg is vertical, on the line x=1. The point where these intersect, D(1, 3) is the vertex of a right angle. Any right triangle inscribed in a circle has its hypotenuse as the diameter of the circle.
Since the triangle is a right triangle, the circumcenter is the midpoint of the hypotenuse: ((8, 3) + (1, -5))/2 = (4.5, -1).
