Answer:
1.5 min
100 rotations
Step-by-step explanation:
to find 300 rotations time duration use the half-minute,
to find half of a minute divide the amount in one minute (200) by 2
200/2 = 100
then mutiply the 100 times 3 to find the time
100 * 3 = 300
therefore 30 sec (100 rot.) and 3 (3 times)
30 * 3 = 90
90 seconds minus 60 (one minute) is 30
so then it is equal to 1.5 minutes aka 1 min. 30 sec.
How long does it take to complete 300 rotations? 1.5 minutes (1 min. 30 sec.)
How many times does it rotate in a half minute? 100 rotations
hope this helps:)
Well, +10 and -10 can do that job.
It's C
first keep C in one side and other in other side of equation like this:
9c/5= F-32
now multiply both side by 5 or do cross multiplication
then it becomes
9c=5(F-32)
now divide both side by 9
c=5/9(F-32)
The answer is A). 5*4=20 one fifth is 4.
