Malachai is doing a 20 miles bike ride. He has cycled 11 miles so far. What percentage of the the total distance has he cycled
Anestetic [448]
11 miles / 20 miles =.55
.55 x 100 = 55%
11/20 is the proportion and you multiply by 100 to gey a percent
another way to solve is
11/20 x 5/5 = 55/100 = 55%
you multiply by 5/5 because it is equal to one and it makes the denominator equal to 100 it also follows the rule that whatever you do to the top you must do with the bottom

Reika [66]

Answer : Option 'b' is correct.

Explanation :

Since we know that  the length of apparent solar day= 24 hours approximately

And the length of  normal days  = 23 hours 56 minutes 4.1 seconds

So, the approximate length of an apparent solar day from June 21, 2010 to June 22, 2010 will be 24 hours  0 minutes 4.1 seconds .

As we increase the length of normal days by 4 minutes .

So, Option 'b' is correct.
