The question states that Mrs. Hadley spent $126.97 on one month, $237.81 on the next, and $198.42 on the last. To get the total, we can add these values together.

An estimation would be:

We can use this estimation to determine that the total value is reasonable.

Step-by-step explanation:
Answer:
A= 75686400
B= 7568640000
C= 75686400000
Step-by-step explanation:
1 day= 1440 min
1 year= 365 days
365 days*1440 min= 525600 min , 1 year= 525600 min
525600 min*2 years= 1051200 min
(in 2 years) 72 beats*1051200 min= 75686400
(in 200 years) 75686400*100= 7568640000
(in 2000 years) 7568640000*10 =75686400000
A butterfly can fly 82 feet in 4 seconds.
Distance traveled by butterfly = 82 feet.
Time taken by butterfly =4 seconds
Speed = distance /time
Speed of butterfly = 82/4 = 20.5 feet/second
A dragonfly can fly 50 feet in 2 seconds.
Distance traveled by dragonfly =50 feet.
Time taken by dragonfly =2 seconds.
Speed of dragonfly = 50/2 = 25 feet/second
So dragonfly can fly faster than the butterfly.
Difference in speed = speed of dragonfly - speed of butterfly = 25-20.5 = 4.5
So The dragonfly is 4.5 feet per second faster than butterfly.
Answer: B) The dragonfly is 4.5 feet per second faster.
