What is the value of the expression below.4/5+3/5+3.5×5

18.9

Step-by-step explanation:

4/5  +  3/5  +  3.5  * 5

Well using PEMDAS you would need to do 3.5 x 5 which is 17.5

After that you would to 4/5  + 3/5 which is 7/5 also as 1  2/5

Then you would do 7/5  +  17.5 = 18.9

I might be wrong but that is what I got and I hope it helps you :)

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
