Answer:

  • Yes

Step-by-step explanation:

Solve each equation and compare the solutions

1.

  • 2(a - 1.1) = 5.8
  • a - 1.1 = 5.8/2
  • a - 1.1 = 2.9
  • a = 2.9 + 1.1
  • a = 4

2.

  • (5/2)b - 2 3/4 = 7 1/4
  • 2.5b = 7 1/4 + 2 3/4
  • 2.5b = 10
  • b = 10/2.5
  • b = 4

Both a and b have same value

The figure shows a plane slicing through a cone. The plane is neither parallel nor perpendicular to the base of the cone, and th

<h3>Answer:   Ellipse</h3>

==================================================

Explanation:

Imagine that this plane was a saw blade, or a laser, that cut the cone. We would have two pieces and each piece would have a shape of an ellipse on them. The cutting plane would also have the same ellipse shape.

Or you think of the cutting plane as a flat piece of cloth. If we cut everything around the cone, then we would have an ellipse shaped hole as a result.

The reason why we get an ellipse and not a circle is because the plane is angled like that. It needs to be perfectly parallel to the circular base in order to get a circular cross section.

Tom decides to paint one wall in his room green. Use the dimensions below to calculate the area of the this wall.
Anton [14]

Option C:

Area of the wall =94\frac{15}{16} square feet

Solution:

Length of the wall = 12 \frac{1}{4} feet

Width of the wall = 7 \frac{3}{4} feet

Area of the wall = length × width

                          $=12 \frac{1}{4}\times 7 \frac{3}{4}  

Convert mixed fraction into improper fraction.

                          $=\frac{12 \times 4+1}{4}\times  \frac{7\times 4+3}{4}

                          $=\frac{49}{4}\times  \frac{31}{4}

                          $=\frac{1519}{16}

Convert improper fraction into mixed fraction.

                          $=94\frac{15}{16}

Area of the wall =94\frac{15}{16} square feet

Option C is the correct answer.
