7 9/12 = 7.75
2 11/12 = 2.917
So we can round both of these up.
7.75 rounds to 8
2.917 rounds to 3
8 + 3 = 11
So the estimated sum is 11.
7 9/12 + 2 11/12 = 10 2/3
So the actual sum is 10 2/3.
The estimated sum is a pretty good estimate to the original number.

Answer:
x=xy/x
Step-by-step explanation:
Answer: x < 3 or x ≥ 11
(-∞, 3) or [11, ∞)
Step-by-step explanation:
subtract 4 from each side
2x < 6 . or . 3x ≥ 33
x < 3 or x ≥ 11
make sure you have an OPEN DOT at 3 pointing to negative infinity and a CLOSED DOT at 11 pointing to positive infinity.
Answer:
V = 2,495.5 ft³
Step-by-step explanation:
Volume of the given cylinder = πr²h
Where,
π = 3.14
radius (r) = ½(17) = 8.5 ft
height (h) = 11 ft
Plug in the values into the formula
V = 3.14 × 8.5² × 11
V = 3.14 × 72.25 × 11
V = 2,495.515
V = 2,495.5 ft³ (to nearest tenth)
