V = π*r^2*h
(9000 in^3/min)*(10 min) = π*(72 in)^2*h
h = (90,000 in^3)/(5184π in^2) ≈ 5.5 in
Answer:
17n+11
Step-by-step explanation:
Formula For Perimeter Of Rectangle: 2(Length) + 2(Width)
Length = 3.5n + 9
Width = 5n - 3.5
____________________________________________________
-> 2(Length) + 2(Width)
-> 2(3.5n+9) + 2(5n-3.5)
*distribute*
-> (7n+18) + (10n-7)
*distribute*
->7n+18+10n-7
->17n-11
-7 is correct because a negative plus a negative is always a negative
65+2i is the answer- I am almost 100 percent sure
Answer:
The number is -4.
Step-by-step explanation:
Let the number be n.
Given:
Max adds 7 to a number.
hence it is given as n+7
Multiply's the sum by -4 the result is 3 times the same number.
Hence the equation can be written as;

Now Solving the above equation to find value of n we get;

The value of n is -4.
Now when we add 7 to number -4 we get answer as 3.
And when the sum is multiplied by -4 we get answer -12.
Also 3 times of number is equal to 3 multiplied by -4 we get answer as -12.
Hence when the sum is multiplied by -4 it is equal to 3 times of same number.
Hence from above we can say that the number is -4.
