Find the gradient of the line joining the points (5,4) and (9,12)
i'm not sure i quite understand, could you provide more information?
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

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.
let's check the answers to see if they are proportional.
question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.
question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.
question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other
question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
