Answer:
5. 9 8. 
Step-by-step explanation:
a²+b²=c²
so for #5 12²+b²=15²
144+b²=225 (subtract 144 from both sides)
b²=81
b=9
For #8
9²+b²=11²
81+b²=121 (subtract 81 from both sides)
b²=40
b=
=

Answer:
As we can see the average for the thickness of a chickens egg shell is 0.311 mm and if we want to round this number to the nearest tenth we just need to see the second decimal place and round to one decimal place.
This second decimal place for this number is 1 and this number is
so then if we round to the nesrest tenth we will get:

Step-by-step explanation:
We use the following info in order to complete the qeustion:
Round the thickness of the shell to the nearest tenth.
