If sound travels 19.8km in 1minutes, how far does it travel in 1sec

km/s or 0.3333333 km/s (you can round to whatever value you need to)

Step-by-step explanation:

We can write the rate at which sound travels as the fraction km/min

As there are 60 seconds in a minute, we can replace the 1 min with 60 seconds in this fraction km/s.

When reduces, this fraction gives us: km/s or 0.3333333 km/s (you can round to whatever value you need to)

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
