Question

A bee flaps it's wings about 82,800 times an hour, and a hummingbird flaps it's wings about 28,800 times an hour. About how many times faster does a bee flap it's wings than a humingbird? Estimate using a single digit times a power of 10. ( Please help me : 100 Points!!! Please help.)

Answer 2

Answer :
`2.67* 10^0` times faster does a bee flap it's wings than a hummingbird.

Step-by-step explanation :

As we are given that:

A bee flaps it's wings about 82,800 times an hour.

We can write 82,800 as, 80,000 by rounding off.

80,000 is in standard form.

The scientific notation of 80,000 is,
`8* 10^4`

A hummingbird flaps it's wings about 28,800 times an hour.

We can write 28,800 as, 30,000 by rounding off.

30,000 is in standard form.

The scientific notation of 30,000 is,
`3times 10^4`

Now we have to determine the how many times faster does a bee flap it's wings than a hummingbird.

`(8* 10^4)/(3* 10^4)`

`(8)/(3)* 10^((4-4))`

`(8)/(3)* 10^0`

`2.67* 10^0\approx 3`

That means about 3 times faster.

Therefore, the
`2.67* 10^0` times faster does a bee flap it's wings than a hummingbird.
