Speed of the sound =  meters per second

Time to calculate the distance traveled =  3*10' 10 seconds

Since,

1.0*10 ' 13

Distance = Speed x Time

Using the values we get:

distance =3.4*10'2*3+10´30

3.4*3*10' (2+10)

10.2*10' 12

Since the calculators show the final answer is scientific notation, the above answer in scientific notation would be:

Distance = 1.02*10°13

The cost of parking a motor home in a state park includes a one time fee of $180, plus a daily rate of $55 per day. Anthony prep
HACTEHA [7]

Answer:

Anthony paid for 7 days of parking.

Step-by-step explanation:

From the information given, the cost of parking a motor home in a state park would be equal to the one time fee plus the result of multiplying the daily rate for the number of days:

c=180+55x, where c is the cost of parking the motor home and x is the number of days.

Now, you can replace c with 565 that is the amount Anthony prepaid and you can solve for x to be able to find the number of days he paid for:

565=180+55x

565-180=55x

385=55x

x=385/55

x=7

According to this, Anthony paid for 7 days of parking.
