-46/60

Step-by-step explanation:

find a common denominator. multiply that number you got that common denominator with for the numerator (top number) and there is your answer

-43/60

Step-by-step explanation:

-5/12-3/10

You need to start by identifying a common denominator. I used 120, so you need to multiple -5/12 by 10 in the denominator as well as in the numerator. (-50/120). Then for 3/10 you need to multiply the top and bottom by 12 which gives you (36/120). Then you subtract -50/120-36/120. Since it is a negative minus a positive you add the two numerators and get an answer of -86/120 which simplifies to -43/60.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
