<u>Skills needed: Time Units Conversion</u>
Step-by-step explanation:
1) First, we need to understand how to convert between hours, minutes, and seconds.
There are 60 minutes in 1 hour ==> 1 hour = 60 minutes
There are 60 seconds in 1 minute ==> 1 minute = 60 seconds
- This means that there are 3600 seconds in 1 hour ()
- This also means that there are 60 minutes in 1 hour
2) We are trying to find how many minutes (or seconds) 40% of an hour is.
---> When converted to decimal,
40% of an hour = 0.4 hours
Since there are 60 minutes in an hour, there are minutes in 0.4 hours.
so, 24 minutes in 0.4 hours.
Since there are 3600 seconds in an hour, there are seconds in 0.4 hours.
so, 1440 seconds in 0.4 hours.
Answer:
16
Step-by-step explanation:
To calculate x we must use the trig function of tangent:
as tangent is opposite divides by adjacent we can get this equation:
which is equal to:
So x must equal to 15.588.. (just put the second bit in the calculator
As all the values provided are integers you round this to the nearest whole number:
16 (as the third digit, 5, rounds up)
so our answer is 16
