Point o is the center of the circle. what is the value of x?
answer options: 9, 17, 8, 15

x = 15

Step-by-step explanation:

OP and PQ intersect at right angles since PQ is tangent to the circle. This implies that OQ will be the hypotenuse in the right angled triangle OPQ.

Applying Pythagoras theorem;

17^2 - 8^2 = x^2

x = 15

40% off the regular price is the correct answer.

step-by-step explanation:

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
