55.04 is 256% of 21.5
Hope it helps and hope its right...---
The volume of the original cylinder is
... V = π·r²·h
For r=1 and h=1, this is
... V = π·1²·1 = π
For the new cylinder, the volume is 1.089 times that amount.
... V = 1.089π = π·1.1²·(1-k)
... 1.089/1.21 = 1-k
... k = 1 - 1.089/1.21 = 1 - 0.9 = 0.1 = 10%
The appropriate choice is (B) 10.
A regular dice ???????????
Answer:
k=2/3
Step-by-step explanation:
Step 1:
Step 1 in solving the exponential equations is re-writing the base same as other side of the equation
so,
Step 2:
Second step is equating the exponents
The rule used is:
So in this case
So the solution is:
k=2/3 ..
784/4 = 196
196 * 4 = 784
4 * 196 = 784
So the answer is : 196
