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 and Explanation:
Alzheimer's disease is a neurodegenerative disease that is initially characterized by the loss of memory, which is followed by alterations in the mechanisms involved in language, reasoning, visuospatial skills and perception of reality.

During preschool years, children develop the <u>b. ability to wait for their turn to participate in an activity</u>.
<h2>
Explanation:</h2>
In preschool, children enjoy doing new things and are more creative. They would rather prefer playing in group than being alone. They cooperate with other children in doing things or activities. They got excited and like to take turns in games or activities.
The kids around 3 to 5 years always expect new things and toys. They are more likely to develop a positive and healthy relationship with others.
For example, when they are playing cards games, they get excited for their turn. Another example is when a child does something and when the adults around the child encourage or clap then they do it with more excitement.
So, the children always wait for their turn to participate.
