Answer: y=6
Step-by-step explanation:
The given number is y.
According to the question,
Step 1 . subtracts three from the number (y-3), then doubles it
i.e. Final number = 2(y-3)
Step 2 . subtracts three again i.e. (2(y-3)-3), and doubles the number again
i.e. Final result = 2(2(y-3)-3)
If the result is his original number y, then
2(2(y-3)-3) =y
⇒ 2(2y-6-3)=y [ using distributive property]
⇒ 2(2y-9)=y
⇒ 2(2y)-2(9)=y [ using distributive property]
⇒ 4y -18=y
⇒ 4y -y= 18
⇒ 3y= 18
⇒ y= 6 [Divide both sides by 3]
Hence, y=6
To find the amount of time between two events, we can use subtraction, just like we do with regular subtraction problems. The subtraction will look something like this:
10:33
-
7:18
Like in a regular subtraction problem, we can subtract the digits that line up, like 10 and 7. Subtracting all of the corresponding digits, we get that it took Tony 3 hours and 15 minutes to finish baking the cookies.

Formula:
V= pi×radius square × height
Remember pi is 3.14
Height= 4 feet
Radius 14 feet
Plug in the numbers into the formula
3.14 × 14^ 2 × 4 = 2461.76 cubic feet
ANSWER: C. 2461.76
