The following show a change of scale made by an architect in one of his drawings. Old: 1 inch = 16 meters. New: 1 inch = 2 meters. Which is the change in scale factor from the old scale to the new scale?
1 to 8
2 to 8
8 to 1
8 to 2

8 to 1

Step-by-step explanation:

16 divided by 2 is 8. 2 divided by 2 is 1. 8 to 1 is your answer, hope it helps!

8 to 1

Step-by-step explanation:

if old  equals 16 and new equals 2 if you divide both by two you get 8 to 1

∠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°

20%
