Answer:
23/99
Step-by-step explanation:
set up an equation
x = 0.232323...
100x = 23.2323...
use elimination
100x = 23.2323...
- (x = 0.232323...)
-------------------------
99x = 23
divide by 99
x = 23/99
Answer:
The answer would be 8.1
Step-by-step explanation:
For the smaller triangle, you use the pythagorean theorem. a squared + b squared = c squared.
To find one of the legs, you do 5 squared - 3 squared = b squared.
25 - 9 = b squared. (BD)
16 = b squared
4 = b
Now for the bigger right triangle. You still use the same tactic.
7 squared + 4 squared = c squared (which is AB)
49 + 16 = c squared
65 = c squared
That means c would equal: square root of 65, which is 8.0622577483 which rounds to 8.1
Add the frequency’s together:
84 + 36 + 72 + 84 + 204 = 480
Divide each frequency by the total then multiply by 360 degrees:
A = 84/480 x 360 = 63 degrees
B = 36/480 x 360 = 27 degrees
C = 72/480 x 360 = 54 degrees
D = 84/480 x 360 = 63 degrees
E = 204/480 x 360 = 153 degrees
