Answer:
C. 128/3 meters cubed
Step-by-step explanation:
The volume of a cylinder is denoted by: 
, where r is the radius and h is the height. We know it's equal to 64, so we can set that equal to V:
We know that the sphere and cylinder have the same height and radius. However, the "height" of a sphere is actually the same as its diameter, which is twice its radius. Then, we can replace h in the above equation with 2r:
Now, the volume of a sphere is denoted by: 
, where r is the radius. From above, we know that 
, so we can plug this into the equation:
Thus, the answer is C.
Answer:
7.5
Step-by-step explanation:
10x + 8x + 6x = 180°
24x = 180°
x = 180°÷24
× = 7.5
Answer:
then 2x = 0 and x - 3 = 0
Step-by-step explanation:
Answer:
Step-by-step explanation:
The current that flows through most substances is directly proportional to the voltage V applied to it. The German physicist Georg Simon Ohm (1787–1854) was the first to demonstrate experimentally that the current in a metal wire is directly proportional to the voltage applied: I∝V I ∝ V .
I believe it is LETTER A.
There are 4 spots to be filled and the order matters. When order matters you have to use Permutations (P).
The first spot has a requirement that the number has to be greater than 7. There are only 2 numbers in the set that are greater than 7, 8 & 9.
So for spot 1 you have 2P1.
You have 4 remaining spots to fill and the order still matters so it will be another permutation. Since you cannot use repeats, we only have 9 numbers left to choose from and we are going to fill the 3 slots with these 9 numbers. 9P3
Only choice A has these options
