For every one litre of water used to make medicine, 150 ml of sucrose and 600 ml of saline solution is used. Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form

20 : 3 : 12

Step-by-step explanation:

For every 1 litre, 150 ml of sucrose and 600ml of saline solution is needed.

1litre = 1,000 ml

Water = 1,000 ml

Ratio:

1,000 : 150 : 600

Divide by 50 to get simplest form:

20 : 3 : 12

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
