Answer:
The area of the tablecloth showing is approximately 45.55 square feet
Step-by-step explanation:
The diameter of the dinner table, D = 8 feet
The diameter of each plate, d = 1 feet
The number of people at the dinner table = 6 people
The number of plates = 6 plates
The area of the table cloth, A₁ = π·D²/4
∴ A₁ = π × 8²/4
The area covered by the 6 plates, A₂ = 6·π·d²/4
A₂ = 6 × π × 1²/4
Let 'A' represent the area of the tablecloth showing when the table is set for six people, we have;
A = A₁ - A₂
∴ A = π × 8²/4 - 6 × π × 1²/4 ≈ 45.55 ft.²
The area of the tablecloth showing when the table is set for six people, A ≈ 45.55 ft.²
11 more than five of a certain number would be written as 5x+11 and it is (means equal to) twenty more than two times that number, which would be 2x+20. So the equation would be
5x+11=2x+20
-2x -2x (get the x's on one side)
3x+11=20
-11 -11 (get the numbers on one side)
3x=9
/3 /3 (divide by 3, so you can get the x by itself)
X=3 (the number is 3)
Answer:
3060 cm^2
Step-by-step explanation:
First, let's find the areas of the trapezoids.
Next, let's find the area of the bases (the top rectangle and bottom rectangle).
- Top: 6 × 30 = 180
- Bottom: 34 × 30 = 1020
- 1020 + 180 = 1200.
After that, we find the surface area of the side rectangles.
- 17 × 30 = 510
- 25 × 30 = 750
- 510 + 750 = 1260.
Lastly, we add 1260, 1200, and 300 together.
Therefore, the surface area should be 3060 cm^2.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
