If he is to receive 200 ml per hour, then after 6 hours he has received 200*6 which is 1200 ml
Answer:

Step-by-step explanation:
So we have:

Remove all the fractions to make things simpler. To do so, we can multiply by the LCM of the denominators.
The denominators are 3 and 7.
The LCM of 3 and 7 is 21. Thus, multiply everything by 21:

Distribute:

Simplify the fractions:

Add 12x to both sides:

Subtract 9 from both sides:

Divide both sides by 26:

Reduce:

And that's our answer :)

Triangular prism and rectangular prism
Answer:
Width: 9 inches
Step-by-step explanation:
1. We can see that the height increased by 6 inches, provided a difference of 15 and 9. If the question states that the frame's dimensions were proportionately enlarged, perhaps the height's enlargment could be benificial
2. If we were to take a ratio where the increased height is over the previous height (height enlargment/prior height) that would be 6/9, or in other words, can be simplified to be 2/3
3. We can see that if the width were to be enlarged, we might be able to determine how much it should be enlarged through a proportionality, provided <em>the frame's dimensions are proportionately enlarged.</em> Now if x ⇒ the width enlargment: 2 / 3 = x / 5.4
4. Through cross multiplication, let us solve for x:
2 * 5.4 = 3 * x,
10.8 = 3 * x,
x = <em>3.6 inches by which the width should be enlarged</em>
5. If we are to determine the new width of the frame after enlargment, add <em>5.4 to 3.6 ⇒ the width of the frame ⇒ 9 inches</em>
