Answer:
4/12 or 1/3
Step-by-step explanation:
there is a fraction of 4 hours in the 12 hours, so 4/12.
That can be simplified to 1/3.
Answer:
(9(x+3))-5
Step-by-step explanation:
Answer:
If AB is a tangent to the circle, the triangle ABO is right angled, as the angle where a tangent meets the circumference is always 90 degrees.
We also know that Pythogoras' theorem only holds for right angled triangles.
The hypotenuse is 12 + 8 as 12 is the radius so is 20.
16^2+12^2 = 256 + 144 = 400 = 20^2 so AB must be tangent.
3 = 379.25
4 = 1587.50
5 = 198.88
6 = 1217.50
7 = 1788.20
8 = 1408
9 = 205
10 = 1516
11 = 2034
12 = 880
13 = 1994.57
14 = 1157.77
15 = 38812.50
remember to round the numbers, and also write random numbers everywhere so it looks like you did it.
