Answer:

21.25 seconds

Step-by-step explanation:

In miles per second, the speed of the jet is ...

(720 mi/h)/(3600 s/h) = 1/5 mi/s

The speed of the sound is the same:

(1 mi)/(5 s) = 1/5 mi/s

Then the rate of closure between the airplane and the sound is ...

(1/5 mi/s) +(1/5 mi/s) = 2/5 mi/s

To find the time required to close a gap of 8 1/2 miles, we can use the relation ...

time = distance/speed

time = (8.5 mi)/(0.4 mi/s) = 21.25 s

The pilot will hear the thunder 21.25 seconds after the flash.

Heron wants to buy a video game. The price is regularly priced at 55 dollars. The store has a discount of 20% off and a sales ta

seropon [69]

The amount paid by Heron for the video game is $46.64.

Step-by-step explanation:

Here, the marked price of the video game = $55

The discount percentage on the video game = 20%

Calculating 20% of the $55, we get:

$\frac{20}{100} \times 55 = 11$

So, the discount offered on the video game = $11

Selling Price = Marked Price - Discount

=$55 - $11 = $44

Now, the tax percentage on the video game = 6%

Calculating 6% of the $44, we get:

$\frac{6}{100} \times 44 =2.64$

So, the tax on the video game = $2.64

New Selling Price = Selling Price + Tax

=$44 + $2.64 = $46.64

So, the amount paid by Heron for the video game is $46.64.

hram777 [196]

Answer:

(1/3) weeks worth of pay.

Step-by-step explanation:

Keith has 3(1/12) weeks worth of pay in a wallet.

Keith has 3(5/12) weeks worth of pay in the bank.

How many more weeks of pay is in Keith's bank than Keith's wallet?

The number of weeks more of pay in Keith's bank than Keith's wallet

= (Number of weeks worth of pay in the bank) - (Number of weeks worth of pay in the wallet)

= 3(5/12) - 3(1/12)

= (4/12) = (1/3) weeks worth of pay.

Hope this Helps!!!
