A 24 inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece is 5 times as long as the first piece. If x represents the length of the first piece, find the length of all three pieces

F=length of first piece=x; S=length of second piece=2x

T=length of third piece=3x

.

F+S+T=24 inches

x+2x+3x=24 inches

6x=24in

F=x=4in

ANSWER 1: The length of the first piece is 4 inches.

.

S=2x=2(4in)=8in

ANSWER 2: The length of the second piece is 8 inches.

.

T=3x=3(4in)=12 inches.

ANSWER 3: The length of the third piece is 12 inches.

.

CHECK:

F+S+T=24in

4in+8in+12in=24in

24in=24in

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
