MODELING REAL LIFE A green roof is like a traditional roof but covered with plants. Plants used for a green roof cost $0.75 per square foot. The roof shown is 40 feet long. How much does it cost to cover both sides of the roof?
Answers
Answer:
$1200
Step-by-step explanation:
Let the roof be square shaped
Area of the roof = L²
L is the side length of the roof
Given
L = 40ft
Area of the roof = 40²
Area of the roof = 1600ft²
If plants used for a green roof cost $0.75 per square foot, this means
1 ft² = $0.75
Let the cost needed to cover both sides of the roof be y, hence;
1600ft² = y
Divide both expressions
1/1600 = 0.75/y
y × 1 = 0.75×1600.
y = 0.75×1600
y = 1200
Hence it will cost $1200 to cover both sides of the roof

Brain has two rectangular sheets of paper.
-The length of the larger sheet is 1 1/2 times the length of the smaller sheet.
-The width of the larger sheet is 1 3/5 times the width of the smaller sheet.
By what factor is the area of the larger sheet greater than the area of the smaller sheet?
Answers
Answer:
2.4
Step-by-step explanation:
Smaller sheet length = 10u
Smaller sheet width = 10u
Smaller sheet area = 10u * 10u = 100u^2
Larger sheet length = 1.5 * 10u = 15u
Larger sheet width = 1.6 * 10u = 16u
Larger sheet area = 16u * 15u = 240u^2
240u^2 / 100u^2 = 2.4
The factor when the area of the larger sheet greater than the area of the smaller sheet should be considered as the 2.4.
Calculation of the factor:Since
Smaller sheet length = 10u
Smaller sheet width = 10u
Now
Smaller sheet area = 10u (10u) = [tex]100u^2[/tex]
And,
Larger sheet length = 1.5 ( 10u) = 15u
And,
Larger sheet width = 1.6 (10u) = 16u
So,
Larger sheet area = 16u (15u) = [tex]240u^2[/tex]
Now
[tex]= 240u^2 \div 100u^2[/tex]
= 2.4
hence, The factor when the area of the larger sheet greater than the area of the smaller sheet should be considered as the 2.4.

The first one says x+2x+4y.
So the first thing you would do is combine like terms.
x and 2x are like terms.
Since x has no number you would have to put a 1 in place for it.
So you would have 1x+2x which would be 3x.
You would then put that together and have 3x+4y.

Only the first point lies on the line and thus, Anders is incorrect
Step-by-step explanation:
Here, we want to show that Anders is incorrect
we simply substitute the values of his coordinates into the equation of the line
for (10,420)
we have;
420 = 40(10) + 20
420 = 420
This is right
We now test the second given point;
-420 = 40(-10) + 20
-420 = -400 + 20
-420 is not -380
