Which geometric series converges ? I still don’t understand . Can someone explain the answer and WHY !
Maurinko [17]

Answer:

B

Step-by-step explanation:

A geometric series will only converge if the common ratio r meets the requirement

- 1 < r < 1

The n th term of a geometric sequence is

a_{n} = ar^{n-1}

where a is the first term and r the common ratio

All terms inside the summation are of this form

The only one with - 1 < r < 1 is B where r = \frac{3}{4} = 0.75

Four people can mow a lawn in 6 hours. How many more people will be needed to mow the lawn in 4 hours, assuming each person mows
ratelena [41]

Answer:

Two more people.

Step-by-step explanation:

If 4 people can mow a lawn in 6 hours, then 4 people can mow 1/6 of a lawn in 1 hour.

If 4 people can mow 1/6 of a lawn in 1 hour, then 1 person can mow 1/24 of a lawn in 1 hour.

If 1 person can mow 1/24 of a lawn in 1 hour, then 6 people can mow 1/4 of a lawn in 1 hour.

If 6 people can mow 1/4 of a lawn in 1 hour, then 6 people can mow a lawn in 4 hours.

6 people minus 4 people is 2 people.
