Step-by-step explanation: Just copy the other cone and find half of the diameter to find the radius the cones are congruent.
Answer is 49.2
Total of all angles = 360
(x+16) + (x) + ( 6x-4) + (2x+16) = 360
10x + 28 = 360
X= 33.2
Angle A = x+16= 33.2+16= 49.2
Answer:
Jay started with $148.5 and Kay with $24.75.
Step-by-step explanation:
With the information provided you know that Jay had 6 times as much money as Kay wich can be expressed as:
J=6K, where
J is the money Jay had
K is the money Kay had
Also, you know that Jay gave Kay $33 and Jay now has twice as much money as Kay, which would be:
J-33=2(K+33)
Now, you can replace J=6K in this equation and solve for K:
6K-33=2K+66
6K-2K=66+33
4K=66
K=24.75
Then, you can replace the value of K in J=6K:
J=6*24.75
J=148.5
According to this, the answer is that Jay started with $148.5 and Kay with $24.75.
Answer:
B. 
Step-by-step explanation:
Total number of students surveyed = 420
