Agroup of 72 students is divided into 9 equal groups for a field trip. there must be 1 adult chaperone for every 4 students. how many chaperones are needed for each group

2 chaperones

Step-by-step explanation:

We will use the math operation division to find the answer. Division takes a total and divides it into equal amounts. We have a total of 72 students and need equal amounts in to each of the 9 groups.

72/9=8 students per group

Since each 4 students need a chaperone, then each group of 8 students needs 2 chaperones. 8/4=2.

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

the answer is 21%.
