V = πr²h/3
Multiply each side by 3.
3V = πr²h
Divide by πr².
3V/πr² = h
Answer:
72 spaces total
Step-by-step explanation:
The ration is 3:5. The 3 is the empty spaces which is 27. In order to simplify 27 to 3, you have to multiply it by 9. Knowing you have to simplify both sides by the same number you then multiple the 5 by 9 getting 45. The total amount of taken spaces is 45. Add the amount of empty spaces and taken spaces together you get 72 spaces total.
Answer:
46.85
Step-by-step explanation:
let the number be n then doubling it is 2n and
2n + 4 = 97.7 ( subtract 4 from both sides )
2n = 93.7 ( divide both sides by 2 )
n = 46.85
Answer: 27
Step-by-step explanation:
Given
In the first sequence, the first term is 
Common difference is 
In the second sequence, the first term is 
Common difference is 
The nth term of the sequence is 
for the same number to appear on both sequence, the nth term must be equal
Put n=4
Therefore, 27 is the first common term in both sequences.
