Answer:
231 ml
Explanation:
Let x represent the amo unt of Dextrose 70% in ml and y represent the amount of Dextrose 5% in ml needed to prepare 1,000mL of Dextrose 20%.
Since 1000 ml of Dextrose 20% is needed, hence:
x + y = 1000 (1)
Also 70% Dextrose is mixed with 5% dextrose to produce 20% dextrose. i.e.:
70% of x + 5% of y = 20% of 1000
0.7x + 0.05y = 200 (2)
We have to solve equations 1 and 2 simultaneously.
Let us multiply equation 2 by 20:
14x + y = 4000 (3)
subtract equation 1 from 3:
13x = 3000
x = 231 ml
Put x = 231 in equation 1 to find y:
231 + y = 1000
y = 769 ml
Therefore 231 ml of Dextrose 70% must be mixed with 769 ml of Dextrose 5% to prepare 1,000mL of Dextrose 20%? *
Answer:
Blood pressure is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in the large arteries.
Explanation:
Blood pressure is measured in units of millimeters of mercury (mmHg). The readings are always given in pairs, with the upper (systolic) value first, followed by the lower (diastolic) value. diastolic blood pressure of 88 mmHg. When your heart beats, it squeezes and pushes blood through your arteries to the rest of your body. This force creates pressure on those blood vessels, and that's your systolic blood pressure. A normal systolic pressure is below 120. A reading of 140 or more means you have high blood pressure.
