Answer:
10:40
Step-by-step explanation:
As the left number increases by 1, the right number increases by 4. So as you can see, the left numbers go 3-4-5 while the right numbers go 12-16-20. So the answer is 10:40 because 10x4=40.
Answer:

Step-by-step explanation:
From the question we are told that:
Radius 
Height 
Rate 
Surface Radius 
Generally the equation for Volume is mathematically given by

Since radius to height ratio gives



Therefore


Generally the equation for Change of Volume is mathematically given by





We know that these two angles are equal to each other (There is the "congruent" sign) so we can set them equal to each other and solve for x
3x - 17 = 25 - 3x
(3x + 3x) - 17 = 25 + (-3x + 3x)
6x + (- 17 + 17) = 25 + 17
6x/6 = 42/6
x = 7
