Determine whether the polygons to the right are similar. If so, write a similarity statement and give the scale factor. If not, explain.

E, Yes. ∆HJK ~ ∆STV. The scale factor is ½.

Step-by-step explanation:

1. Similarity statement

When you name similar triangles, the order of the letters of corresponding angles must be in matching order.

For example, in ∆HJK, ∠H is the right angle, ∠J is the larger acute angle, and ∠K is the smallest angle.

The corresponding parts in ∆STV are ∠S, ∠T, and ∠V.

The similarity statement is

∆HJK ~ ∆STV

2. Scale factor

The scale factor (C) is the ratio of corresponding parts of the two triangles.  

If ∆HJK is transformed to ∆STV, the scale factor is

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
