Answer:
Center: (9, 4)
Radius: 20
Explanation:
(x - 9)² + (y - 4)² = 400
The Circle Formula:
(x - h)² + (y - k)² = r²
where (h, k) is center points, r is radius
Rewrite the equation:
(x - 9)² + (y - 4)² = 20²
Identify following:
h = 9, k = 4, radius = 20
Answer:
angle ABC is 130 degrees
Step-by-step explanation:
This is the quickest and simplest way to gind the answer.
Angle CBD and angle ABC are linear pairs. Linear pairs are supplementary meaning angle CBD and angle ABC equal 180 degrees. Since angle CBD is 50 degrees and you know both angles need to add up to 180 degrees all you need to do is subtract 180 from 50 degrees.
80 miles per hour means it takes one hour to travel 80 miles. If it said 65 MPH (miles per hour), it would take one hour to travel 65 miles.
ANSWER: 1 hour
