How are the distance formula and the pythagorean theorem related to one another?

stira [4]

They are the same because the distance formula depends on a right triangle relationship between x and y, where as the right triangle has the same relationship with x being one leg of the right triangle and y the other leg of the right triangle

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 $A=300ml$
