When you are only concerned with the remainder from division by 9, the arithmetic is said to be "modulo 9." The statement "when x is divided by 9, the remainder is 4" can also be written as
 : x mod 9 = 4
When the mod 9 operation is applied to arithmetic involving x, we really only need to apply it to the same arithmetic on the remainder. That is
(2x +2) mod 9 = (2·4 +2) mod 9 = 10 mod 9 = 1
The remainder of 2x+2 divided by 9 is 1.
_____
In the general case, the mod 9 remainder being 4 means that the value of x can be written in general as
x = 9n+4 . . . . for some integer n
Then the expression 2x+2 becomes ...
2(9n+4)+2 = 18n +10 = 9(2n+1) +1
so when we divide this number by 9, we can see the remainder will be 1

Answer:
<em><u>1</u></em><em><u>1</u></em><em><u>3</u></em><em><u>0</u></em><em><u>9</u></em><em><u>7</u></em><em><u> </u></em><em><u>ft^</u></em><em><u>3</u></em>
Step-by-step explanation:
if 60ft is diameter the radius is 30ft
formulae for volume of sphere is
4/3 πr^3
i.e, 4/3 π (30ft)^3
i.e, 113097.05 ft^3
none of the answer matched so maybe 60 ft not diameter (it's not mentioned clearly, what's it ;)
also. none. of. em. is. closet. answer.
