D is the correct answer.
0.25 is rational because it can be represented as a ratio of integers (1/4).
0.45 is rational because it can also be represented as a ratio of integers (9/20).
When you multiply rational numbers, you always end up with a rational number.
0.25*0.45=0.1125 or 1125/10000
Answer:
from now on don't ask same qn two times or more it would be waste of your points
got it??
5/6-1/3
So you find the common denominator which is 6
5/6-2/6=3/6
Answer is 1/2
Answer:
The volume of cone z has the same base area as cylinder y but its height is 3 times the height of cylinder y have the same volume.
Step-by-step explanation:
The volume of a cylinder having base area 'A' and height 'H' is given by V = AH, and the volume of a cone having the same base area as the cylinder i.e. A and height 3 times the height of the cylinder i.e. 3H is given by
.
So, V = V'
Hence, the volume of cone z has the same base area as cylinder y but its height is 3 times the height of cylinder y have the same volume. (Answer)
