<span>This one is hard to explain in print. Let x be the side of the rectangle on the hypotenuse and y be the other side. There is a triangle formed at the right angle of the original which is similar to the original.
So x is to 10 as z is to 8: x/10 = z/8
and z = 4/5 x
The upper part of that leg would be 8 - 4/5 x
The triangle at the top is also similar:
So y is to 6 as (8 - 4/5 x) is to 10: y/6 = (8-4/5 x)/10
and y = 3/5 (8- 4/5 x) = 24/5 - 12/25 x
Now area = xy
Deriv = 0 and solve </span>
Answer:
<em>2 litres of water</em>
Step-by-step explanation:
If Ryan drinks 1 1/2 liters of water every 3/4 of an hour at a constant rate, this can also be expressed as;
1 1/2 litres = 3/4 hour
To get the amount of litres Ryan drank for 1 hour
x = 1 hour
Divide both equations
(3/2)/x = (3/4)/1
3/2x = 3/4
2x * 3 = 3 * 4
6x = 12
x = 12/6
x = 2
<em>Hence Ryan drinks 2 litres of water in an hour</em>
Answer: 4
Step-by-step explanation:
