The tangent secant theorem says
PR × PS = PQ²
4 × (4+5) = PQ²
36 = PQ²
PQ=6
Answer: 6
Answer: 0.70
Step-by-step explanation the same as decreased by 30%" would be (1.00 - 0.30)(original cost), or 0.70(original cost)
50 miles = 1 hour
50 x 1 = 50
a. 50 miles x 2 hours = 100 miles
b. 50 miles x 4.3 hours = 215 miles
c. Converting minutes to hours, it would make 20 minutes become 0.333 hours.
50 x 0.333 = 16.65 miles
It would be negative seeing the key word is down. (:
Hope I could help!
