In a 100 kg afebrile person with intact skin, insensible fluid loss from lungs and skin is approximately: A) 500 mL/day. B) 800 mL/day. C) 1000 mL/day. D) 1200 mL/day.

Answers

In a 100 kg afebrile person with intact skin, the insensible fluid loss from the lungs and skin is approximately 500 mL/day (Option A).

Insensible fluid loss refers to the water that is lost from the body through evaporation, primarily from the lungs during respiration and from the skin through perspiration. This loss is not easily measurable and occurs continuously throughout the day.

In a person with normal body temperature (afebrile) and intact skin, the average insensible fluid loss is estimated to be around 500 mL per day. This loss helps maintain the body's fluid balance and temperature regulation.

It's important to note that this estimation can vary depending on various factors such as ambient temperature, activity level, and individual variations. However, in the given context, the most appropriate and accurate answer is Option A: 500 mL/day.

1.D 2. A 3.C 4.D

1 Is the monomial as it only contains one expression.

2. Is the difference of squares because something squared minus something squared.

3. Is standard because it is of the form

a_nx^n+ a_(n-1)x^(n-1)+...+a_1x+a_0

4. We know D is the not the monomial simply because its power is negative which means it does not fit the definition of a polynomial.

The sum of two numbers is 52 . The larger number is 2 less than twice the smaller number .What are the numbers

Answers

Answer:

35.34 and 16.66

Step-by-step explanation:

Given data

let the numbers be x and y

the smaller number = x

the larger number = y

x+y=52--------1

The larger number is 2 less than twice the smaller number

y=2x-2-------2

put y= 2x-2 in eqn 1

x+2x-2=52

3x-2=52

3x=52-2

3x=50

x= 50/3

x= 16.66

put x=16.66 in eqn 1 to find y

x+y=52

16.66+y= 52

y=52-16.66

y= 35.34

Hence the numbers are

35.34 and 16.66

Check

35.34+16.66= 52
