Answer:
286 ml of water
Explanation:
Since 500ml Of Dextrose 30% is needed to be produced from Dextrose 70%. Let us assume that x ml of Dextrose 70% is mixed with water to get 500 ml of Dextrose 30%. Hence:
30% of 500 ml = 70% of x
70x = 15000
Dividing through by 70:
x = 214 ml
Therefore 214 ml of Dextrose 70% is used
The amount of water used is gotten using:
amount of water = Amount of Dextrose 30% - Amount of Dextrose 70%
amount of water = 500 ml - 214
amount of water = 286 ml of water
Answer:
urethra
Explanation:
This tube allows urine to pass outside the body. The brain signals the bladder muscles to tighten, which squeezes urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax to let urine exit the bladder through the urethra.
The answer is C!!!!!!!!!!!
Blood alcohol content (BAC) is a measure of the amount of alcohol that is present the blood.
A heavier person will have a lower blood alcohol level due to a greater amount of water in their body. The more a person weigh, the more water he/she tends to have in his/her body. The water has a diluting effect on the alcohol so the BAC will be lower in comparison with person who is slimmer and has less water in the body.
