Answer:
11.16
Step-by-step explanation:
4sf=four numbers
if 0 is first number, leave it out because 0 is a significant figure
X = 42 - 19, so A - x = 23
The number that is given in the question and that needs to be converted is
3.0 * (10)^10 cm/s
This can be simplified and written as 30000000000 cm/s. It has to be converted to ft/s.
1 cm = 0.0328084 feet
Then
30000000000 cm = 0.0328084 * 30000000000 ft
= 984252000 ft
So
3.0 x (10)^10 cm/s = 984252000 ft/s
I hope the answer has come to your help.
