Question 2A please! :)
Answers
In order to use mental math, we'll round up each value to the nearest whole number. Here's what we'd have: 10 + 9 + 11 + 9 + tax. Next, add the values together. We know that 9 and 11 equal 20, so then adding another 9 would give us 29, and adding a 10 would give us 39. To add tax, we can round up to 10%, which would give us 3 dollars and 90 cents, which can be rounded up to 4 dollars. Lastly, add 39 and 4 to give you a mental math answer of $43.
Hope this helps!! :)

Step-by-step explanation:
The circumference (C) is calculated as
C = πd ← d is the diameter
diameter = 2 × 9 = 18 in ( twice the top diameter ), thus
C = 18π in ← exact value ≈ 56.55 in ( to 2 dec. places )
The circumference of the bottom of the lamp shade is 56.55 inches
What is circumference of circle?
The circumference of a circle is the perimeter of the circle. It is the totallength of the boundary of the circle.
The diameter of top of shade(d₁) = 9-inch
The diameter of bottom of shade(d₂) = 2(d₁) = 2(9) = 18 inch
The circumference (C) of bottom of shade :
C = πd₂ = π × 18
C = 18π ≈ 56.55 inches

==========================================
Even though you haven't asked for the solution,
I'm here already so I might as well go through it:
-(4 and 2/3) = 2n/3 + 1/3 + n/3
Combine the 'n' terms on the right side:
-(4 and 2/3) = n + 1/3
Change (4 and 2/3) to an improper fraction:
-(14/3) = n + 1/3
Multiply each side by 3 :
-14 = 3n + 1
Subtract 1 from each side:
-15 = 3n
Divide each side by 3 :
-5 = n
