Answer:
PR = 53.18°
Step-by-step explanation:
Given:
m<PTR = 61.99°
arc SQ = 70.80°
Required:
Measure of arc PR
Solution:
Based on the theorem of angles with vertex inside the circle and intercepted arcs, we would have the following equation:
m<PTR = ½(PR + SQ)
Plug in the values
61.99 = ½(PR + 70.80)
Multiply both sides by 2
2*61.99 = PR + 70.80
123.98 = PR + 70.80
123.98 - 70.80 = PR
53.18 = PR
PR = 53.18°
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
Answer:
y/x
Explanation:
The constant of proportionality defines two directly proportional quantities that decrease or increase proportionally/same rate.
Given constant of proportionality= k
Side of the square= x
Perimeter of the square= y
constant of proportionality=k=y/x
For example if perimeter of square is 8 and side of square is 2, constant of proportionality is 8/2=4
The answer is D. 15+18+12+5= 50 and there are 5 ramblers
Answer:
y = -7/6x +7
Step-by-step explanation:
To get y by itself, divide by its coefficient.
(42 -7x)/6 = y
We can simplify this and swap sides to get ...
y = -7/6x +7
