The Parkland formula is
V = 4mA
where
V = volume of replacement fluid (mL) required within the first 24 hours after a burn injury,
m = body mass, kg
A = percent of body surface area covered with burns.
The first half of the fluid should be delivered in the first 8 hours.

Because we are concerned with fluid replacement within the first 8 hours, the Parkland formula is valid to be used.
 
Given:
m = 75 kg
A = 40%

Therefore
V = 4*75*40 = 12,000 mL = 12 L
This is the fluid replacement required in the first 24 hours.

Because half of this amount should be delivered in the first 8 hours, the amount of fluid replacement is
6,000 mL in 8 hours, or
6000/8 = 750 mL per hour.

Answer:  750 mL every hour

The sum of two consecutive negative integers is -171. What is the number closest to zero?
Anton [14]
Consecutive numbers are always 1 away from each other
3,4

so consecutive is represented by
x and x+1
so sum is -171
x+x+1=-171
add like terms
2x+1=-171
subtract 1 from both sides
2x=-172
divide both sides by 2
x=-86
subustitute
x+1=otehr number
x+1=-86+1=-85
answer is -85 and -86

Solve the following equation for x.<br> 0.1(x + 250) = 5,000<br> h
yan [13]

Answer:

x=49750

Step-by-step explanation:

0.1(x + 250) = 5,000

Divide each side by .1

0.1(x + 250)/.1 = 5,000/.1

x+250 =50000

Subtract 250 from each side

x+250-250 = 50000-250

x=49750

The Law and Order detectives enter a house at 11:30 am and found a man on the floor murdered. They take his body temperature fin
taurus [48]

Answer:

Time of murder = 10:39 am

Step-by-step explanation:

Let the equation of exponential function representing the final temperature of the body after time 't' is,

f(t) = a(e)^{nt}

Here, a = Initial temperature

n = Constant for the change in temperature

t = Duration

At 11:30 am temperature of the body was 91.8°F.

91.8 = 98.6(e)^{nt} --------(1)

Time to reach the body to the morgue = 12:30 pm

Duration to reach = 12:30 p.m. - 11:30 a.m.

                              = 1 hour

Therefore, equation will be,

84.4 = 91.8(e)^{n\times 1}

eⁿ = \frac{84.4}{91.8}

ln(eⁿ) = ln(0.9194)

n = -0.08403

From equation (1),

91.8 = 98.6(e)^{-0.08403t}

(e)^{0.08403t}=\frac{98.6}{91.8}

ln[(e)^{0.08403t}]=ln[\frac{98.6}{91.8}]

0.08403t = 0.07146

t = 0.85 hours

t ≈ 51 minutes

Therefore, murder was done 51 minutes before the detectives arrival.

Time of murder = 11:30 - 00:51

                          = 10:90 - 00:51

                          = 10:39 am
