The area of a shape is the amount of space it can occupy.
- <em>The same hallway be painted with the same pattern, but using twice as much black paint as white paint</em>
- <em>The length of the hallway is 40 feet</em>
<em />
<em />
From the complete question (see attachment), the length of the white area is:
The width is:
So, the area of the white segment is:
The length of the black area is:
The width is:
So, the area of the black segment is:
So, their areas are:
--- white area
--- black area
<u>The paints</u>
The equation is given as:
Substitute the areas
Collect like terms
Divide both sides by 36
Because x has a positive real value, then the <em>same hallway be painted with the same pattern, but using twice as much black paint as white paint</em>
<u>Length of the hallway</u>
To calculate the length of the hallway, we simply equate both areas;
Collect like terms
Divide both sides by 6
So, the length of the hallway is the sum of the following lengths:
So, we have:
Substitute 4 for x
So, the length of the hallway is 40 feet

R+2=3. I hope this helped and please mark this as brainliest answer.
Answer:
152.1 cm³
Step-by-step explanation:
Change in Volume = πr²(h₁-h₂)
Where r = 22 cm
h₁ = 10 cm
h₂ = 9.9 cm
ΔV = π x (22)²x (10-9.9)
= π x 484 x 0.1
= 152.11
≈ 152.1 cm³
Triangle A B C is reflected across BC and then is rotated about point C to form triangle D E C.
1) Since SSS Postulate states that if the three sides of one triangle have the same measure as another triangle then both triangles are congruent.
<h3>
What is the consequence postulate?</h3>
The consequence of this Postulate is that these triangles have respectively the same angles.
We have given that,
Triangles A B C and D E C are connected at point C.
Triangle A B C is reflected across BC and then is rotated about point C to form triangle DEC.
2) Notice below both triangles SSS, an example, in this case, an isosceles triangle, firstly reflected (grey one ) then rotated by point C.
