Quantity of water used to make a medicine :-
This quantity of water required to make a medicine = 1000 ml
Quantity of sucrose used to make a medicine = 150 ml
Quanity of saline solution used to make a medicine = 600 ml
The quantity of water to sucrose to saline solution needed to make a medicine as a ratio :-
Cutting each common zero in this ratio, we get :-
Dividing each number in the ratio by 5, we get the ratio :-
Since, the three numbers in this ratio doesn't have any common factors we can conclude that we have found out the simplest form of the ingredients needed to make the medicine .
Therefore, the ratio of water to sucrose to saline solution needed to make a medicine = 20:3:12
Answer:
x = 60
Step-by-step explanation:
X/2-5=25
Add 5 to each side
X/2-5+5=25+5
x/2 = 30
Multiply each side by 2
x/2*2 = 30*2
x = 60
Answer:
Thus to rent <u>10</u> number of videos to get the cost same.
Step-by-step explanation:
Given:
Michael's Video charges member $4 to rent each video. If you get a store membership it costs $20 and members only pay $2 to rent a video.
Now, to find the number of videos to get the cost same.
Let the number of videos to get the cost same be
Charges to rent each video without membership = $4.
Cost of membership = $20.
Charges to rent each video with membership = $2.
Now, to get the number of videos to get the cost same we write and solve an equation:
<em>Subtracting both sides by </em><em> we get:</em>
<em /><em />
<em>Dividing both sides by 2 we get:</em>
Therefore, to rent 10 number of videos to get the cost same.
Answer:
1/16
Step-by-step explanation:
75 of the 80 pass
80-75 = 5
That means 5 did not pass
Fraction that did not pass = people that did not pass/ total
= 5/80
divide the top and bottom by 5
=1/ 16
Answer: 34 jars
