Joel buys a coffee mug for 10 dollars. Sales tax is 5%. How much does Joel actually have to pay?

$10.50

Step-by-step explanation:

You first need to multiply the sub-total amount ($10) by the amount of tax owed (.05) to get the amount spent on taxes. Which is $.50. Next you need to add $.50 to $10 to get the total amount spent.

The answer would be $10.50.

Step-by-step explanation:

The way u get that answer is bydoing 5 cents times every dollar. Now if u do that u get 50 cents. 5x10=50. So your answer is $10.50

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
