Ratios can be written as fractions.....so the ratio of black keys to white keys is 6:8...which can be written as 6/8....which reduces to 3/4...hence the ratio simplified is 3:4......which is also written as 3/4 and as 3 to 4
Ok, so basically, the amount of orange pics is 3/5.
I think better w/ visuals, so i drew 5 circles, and colored 3 orange
Since the 3 circles represent 12 picks (because there are 12 picks total and 3/5 of the picks are orange) you nee to find out how many picks 1 circle represents.
In order to find this, do 12/4=3
One circle equals 3 picks
multiply 3 by 5, and you get 15
Hope this helps because this is a better explanation for visual learners!
The side length has to be between 2 (=9-7) and 16 (=9+7). In both these corner cases the triangle will have collapsed to a line.
So the correct answers are B,C,D and E, and F is a corner case. Theoretically I suppose you have to count F in as a valid answer.
I believe it would be A because it says that the mean time is 6.7 and the standard time is 2.2

Answer:
(c) 16°
Step-by-step explanation:
The external angle at P is half the difference of the intercepted arcs:
P = (90° -58°)/2 = 32°/2
P = 16°
