Answer:
the answer is 14:1
Step-by-step explanation:
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.
Answer:
<u>At Present Jane has Total Stickers = 251</u>
Step-by-step explanation:
Stickers Initially = 27
Jane bought stickers on 1st day = 3
Remaining days = 13
Each next day she bought 2 more stickers than the previous day, so:
Stickers bought in the last 2 weeks (14 days) = n+(n+2)+(n+2+2)+(n+2+2+2)+.............+(n+2(13))
here n =3
So:
Stickers bought in the last 2 weeks (14 days) = 3+5+7+9+11+13+15+17+19+21+23+25+27+29
Stickers bought in the last 2 weeks (14 days) = 224
At Present Jane has Total Stickers = Stickers Initially+ Stickers bought in the last 2 weeks (14 days)
At Present Jane has Total Stickers = 27+224
<u><em>At Present Jane has Total Stickers = 251</em></u>
