Answer:

Step-by-steYou have two angles,

A=32°20'

B=57°40'

so, angle F at the fire, is 90°

d/5 = cosA = .845

d = 4.2 mi

If angle F had not been 90°, then using the law of sines,

d/sinA = 5/sinF

for this problem, sinF = 1p explanation:

A patient requires an IV of D5W, a 5% solution of dextrose (sugar) in water. To the nearest milliliter, how much D20W, a 20% sol
solmaris [256]

Answer:

  A=300ml

Step-by-step explanation:

From the question we are told that

5% solution of dextrose sugar in water

20% solution of dextrose in

100 milliliters of distilled water water

Generally in mathematically solving we call A the amount of D20W added

Since 20% of dextrose is needed

       20 \%*100=20milliter

Total quantity after addition (100+x)

for DW5% total solution is

          5\% (100+A)= \frac{5}{100}(100+A)

          5\% (100+A) =5+0.05A

Mathematically

           5+0.05A =20

           5+0.05A =20-5

           A=\frac{15}{0.05}

           A=300ml

Therefore the required quantity A=300ml

I need help In this please

The answer is x < 12

1) Minus 6 from both sides of the inequality

2) Multiply both sizes by 4

3) Divide both sides by -3

4) Swap the direction of the inequality (You always do this when you multiply/divide both sizes of an inequality)

5) You should have x < 12
