Question 7 3 pts
John left the museum and drove south at a rate of 45 mph. Sally left two hours later driving 20 mph faster
than John in an effort to catch up to him. How long did Sally have to drive to catch up with John?
O 6.2 hours
O 4.5 hours
O 6.5 hours
8.6 hours

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

this is false ^.^ lol

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
