Answer:
geometric t2-t1
Step-by-step explanation:
divide the second term by the first to get the common ratio
I believe the answer is 21
Find the length of AB
AB²=20²+15²
AB²=400+225
AB²=625
AB=25
then find AD and BD
20²=AD·25
400=AD·25
AD=16
15²=BD·25
225=BD·25
BD=9
now use the geometric mean theorem (name?) to find CD
CD=√(9·16)
CD=√144
CD=12 cm
Answer:
The total distance Zoey biked = 120 kilometers.
Step-by-step explanation:
Given that Zoey took 2.5 hours to bike the 60 kilometers from her house to the beach.
Thus,
Distance covered from her house to the beach = 60 kilometers
Given Zoey took 3.5 hours to bike the same distance back to her house.
Thus,
Distance covered from beach to her house = 60 kilometers
Therefore, the total distance can be calculated by adding the distance covered from her house to the beach and the distance covered from the beach to her house.
Total distance = 60 + 60 = 120 kilometers.
Therefore, the total distance Zoey biked = 120 kilometers.
