What you will have to do is times 46.5 by 100 then with that answer you will divide that by 75 and you will get 62%
Find the diameter of circle using pythagoras
d = √(Δx² + Δy²)
d = √((7-1)² + (-6-2)²)
d = √(6² + (-8)²)
d = √100
d = 10
The diameter is 10
Find the circumference
c = π × d
c = 3.14 × 10
c = 31.4
Answer:
9) (68 + 160)/2 = 114°
10) 80/2 = 40°
11) 105 x 2 = 210°
12) 80 x 2 = 160°
13) (360 - 180 - 108)/2 = 36°
14) (360 - 69 - 95)/2 = 98°
45,000-780h=y
It looses 780 gallons per hour so you do 780 time # of hours.
36-12=24
The answer is:
12;24 or 1;2 (simplified)
