For every 1 litre of water used 150ml of sucrose and 600ml of saline solution is used

Question:

For every 1 litre of water used to make a medicine, 600 ml of sucrose and 150ml of saline solution are used.

Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.

Step-by-step explanation:

Given

Required

Express as a ratio to the simplest form

First convert the volume of water to mL

Express as ratio:

Divide through by 10

Divide through by 5

The ratio can not be further simplified

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
