Solve for the value of r

r = 15

Step-by-step explanation:

These angles are supplementary which means they add up to 180:

6r - 4 + 94 = 180

6r + 90 = 180

6r = 180 - 90

6r = 90

r = 15

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
