Answer:
3.682
Step-by-step explanation:
We don't consider the decimal place or I should say comma so then we read from the first digit as long as it's not zero then until the fourth digit we look at the next digit if it's 5 or greater then we add 1 to the previous digit. And if the next digit is less than 5 then the digit won't change
Answer:
-2/radical 3
Step-by-step explanation:
radical 8 can be written as 2 times radical 2
radical 6 can be written as radical 2 *radical 3
you have radical 2 as common for both so you can cancel those
and you remain with -2 on the top and radical 3 on the bottom
so the answer is -2/radical 3
Answer:
[(1/12)(5/5) + (1/20)(3/3)](x hours) = 1
(5/60 + 3/60)x = 1
(8/60)x = 1 we can reduce 8/60 by dividing out a 4
(2/15)x = 1 x both sides by 15/2
x = 15/2
x = 7 1/2 or 7.5 hours
