Answer:-9
Step-by-step explanation:
I think the best value for x is -9 because 6 x -9 = 54, minus 8 equals -44.
So the formula for the circumference of a circle is π x diameter
Since we know the the circumference already, we just divide that by π:
12π / π = 12
Now we halve the diameter to get the radius:
12 / 2 = 6
The area of a circle is π x radius²
So the area is:
·π x 6² = 36π· (or 113 not in terms of π)
Answer:
m<G = 55°
Step-by-step explanation:
m<G = (1/2)[m(arc)LE - m(arc)HF]
m<G = (1/2)[150° - 40°)
m<G = 110°/2
m<G = 55°
Answer:
1.
%K = 31.904%
%Cl = 28.930%
%O = 39.166%
2.
Hg = 80.69/ 200.59 = 0.40/0.2 = 2
S = 6.436/ 32.07 = 0.20/0.2 = 1
O = 12.87/ 16.00 = 0.80/0.2 = 4
Hg2SO4 is the empirical formula
