Answer: 4200
Assuming that this question is based on a graph, and that this graph tells us that people 50-64 years make up 35% of all the voters, then it would mean that
35%of 12000= 35/100 * 12000= 35 * 120= 4200
So, assuming that people at age 50-64 make up 35% of the voters, then 4200 of them voted.
Here is the solution:
m<FDE = 1/2( Arc BC + Arc 76)
m<FDE = 1/2 (61° + 76°)
m<FDE = 137/2 = 68.5°
So the answer is 68.5°

Step-by-step explanation:
P(A and B) = P(A) × P(B)
~~~~~~~~
P(A) =
P(B) = =
P(A and B) = × =
Answer:
The difference between the volume of the two spheres is 791.6m^3.
Step-by-step explanation:
V = 4(pi)(r^3/3)
Sphere 1:
V = 4(pi)(6^3/3)
Solve.
V = 4(pi)(216/3)
V = 4(pi)(72)
V = 4(226.2)
V = (904.8)
Sphere 1 Volume: 904.8m^3
Sphere 2:
V = 4(pi)(3^3/3)
V = 4(pi)(27/3)
V = 4(pi)(9)
V = 4(28.3)
V = 113.2
Sphere 2 Volume: 113.2m^3
Subtract.
904.8 - 113.2 = 791.6
A+b 5
------- = ---
2a-b 4
b 5
-------- = ---- => 9b = 5a+45 => b = (5a+45)/9
a+9 9
a+b 5
------- = --- => 4a+4b = 10a-5b
2a-b 4
9b = 6a
9(5a+45) =6a divide both sides by 3
3(5a+45) = 2a
15a +135 = 2a
13a = -135
a = -135/13 = -10,38
a= -10,38
9b=6a
3b=2a
3b = 2(-10,38)
3b = -20,76
b = -20,76/3
b = -6,92
hope this helped
