A square pond is to be built in a park. The pond is 50 meters long and 50 meters wide. There should be a tile sidewalk 5 meters wide all around the pond. The tile is sold in crates of 45 square meters of tile. What will the tile cost if the cost of each box of tile is $74
Answers
Area = l * w
Area = 50 * 50
Area = 2500 square meters.
Then there is a sidewalk with 5 meters wide around the pond.
So the new dimension is
60 * 60
Area = 60 * 60
Area = 3600
Then at 45 m^2 = $74
= 3600 / 45 * 74
= $5,920
So the total cost of tile is $5,920.

Which of these polygons is not formed by the cross-section created when a plane intersects a cube?
Select all that are possible.

Answer:
The circle cannot be formed.
Step-by-step explanation:
The polygons that are NOT formed when a cube is intersected by a plane would be : circle
A cube has only six plane faces, it is impossible that a plane can intersect a cube and create a cross section with a curved face. So a circle cannot be formed.
A square is formed when a cube is intersected by a plane parallel to its base.
A rectangle is formed when a cube is intersected by a plane in two pairs of opposite faces.
A triangle is formed when a cube is intersected by a plane in three adjacent faces.
circle
pentagon
square, trapezoid, triangle, and rectangle would all be possible.

The formula becomes w = (200P - 20)/3.
What is Equivalent Equation?
- The mathematical equations which give the same value when solved.
- These equations can be interchanged into one another.
- They are very useful in solving mathematical problems.
Given: Formula
P = (3w + 20)/200
Now, we will convert this in the form of P.
⇒ P = (3w + 20)/200
multiply both sides by 200, we get:
⇒ 200 P = 3w + 20
⇒ 200P - 20 = 3w
⇒ w = (200P - 20)/3
Therefore, the formula after making w as the subject becomes:
w = (200P - 20)/3

Answer:
Step-by-step explanation:
I assume the correct formula is
P = (3w + 20)/200
Solve for w.
200P = 3w + 20
200P - 20 = 3w
(200P - 20)/3 = w
