29 If we round to 1 significant figure, sound travels at a speed of approximately 0.3 kilometers per second, while light travels

MrRissso [65]

Answer:

3 x 10^-1 km per second.

Step-by-step explanation:

A scientific notation includes c x 10^n. c is a number between 1-9, and n is the nth power of 10.

If we move the decimal in 0.3 to the right by 1 place, we can get "c", which will be 3. Since we have moved the decimal to the right, each place moved right counts as -1 for n.

So, the answer is 3 x 10^-1 km per second.

In large cities people out and take taxis to get from one place to another the cost is $25.20 every 36 miles how much is a 47 mi

Kay [80]

47 miles taxi ride will cost $32.9

Step-by-step explanation:

Given,

Cost every 36 miles = $25.20

Cost of one mile = $\frac{Cost\ for\ 36\ miles}{36}$

Cost of one mile = $\frac{25.20}{36}\\$

Cost of one mile = $0.7

Cost of 47 miles = Cost of one mile * 47

$Cost\ of\ 47\ miles = 0.7*47\\Cost\ of\ 47\ miles = \$32.9$

47 miles taxi ride will cost $32.9
