Answers:
a) 75ml/hr
b) 0ml left
Explanation:
a) 750ml - 450ml = 300ml (This is how much we know the bag drained within 4hrs)
300ml/4=75ml
so now we know the rate of drain is 75ml/hr
b) since rate is 75ml/hr:
75*6=450
450-450=0
Hence there will be no fluid left for the patient.
The length of the ladder is 13 because: using the pythagorean theorem
a² + b² = c²
5² + 12² = c²
25+144 = 169
169 = c²
Then figure the square root of 169.
13 x 13 = 169
Hope this helps :)
