Howard has a chemical burn from accidentally spilling a strong basic cleaning solution onto his arm. It causes a small burn mark that goes away
after a few weeks. He has no other symptoms. What kind of exposure is this
considered?

a, b, c - sides of a triangle

a + b > c

a + c > b

b + c > a

we have a = 5m and b = 11m. substitute:

5 + 11 > c

16 > c → c < 16

5 + c > 11         subtract 5 from both sides

c > 6

11 + c > 5         subtract 11 from both sides

c > -6

c < 16 and c > 6 and c > -6

thereofre your answer is 6m < c < 16m

aed pads should be placed in the middle of the child's chest. this ensures that the electricity can properly run through the child's body and hopefully cause his/her heart to start again. hope this : )
