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.

Find m∠STU and m∠TUA

Answers

Answers:

angle STU = 65 degreesangle TUA = 123 degrees

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

Explanation:

Let's find the expression for angle TUS in terms of x

Angle TUA has the expression 11x+2. It will add to angle TUS to get 180 degrees

(angle TUS) + (angle TUA) = 180

angle TUS = 180 - (angle TUA)

angle TUS = 180 - (11x + 2)

angle TUS = 180 - 11x - 2

angle TUS = -11x + 178

Now focus on the interior angles of triangle TUS. We have these three angles

T = 5x+10U = -11x+178S = 58

For any triangle, the interior angles always add to 180, so,

T+U+S = 180

(5x+10) + (-11x+178) + (58) = 180

(5x-11x) + (10+178+58) = 180

-6x + 246 = 180

-6x = 180-246

-6x = -66

x = -66/(-6)

x = 11

Use this x value to find the angle measures we're after:

angle STU = 5x+10 = 5*11+10 = 55+10 = 65 degreesangle TUA = 11x+2 = 11*11+2 = 121+2 = 123 degrees

--------------------------

As an alternative route, you can apply the remote interior angle theorem. This says that adding two interior angles leads to the exterior angle that isn't adjacent to either one.

In this case, we would say

(angle STU) + (angle TSU) = angle TUA

that leads to the equation

(5x+10) + (58) = 11x+2

Solving this should lead to x = 11 to generate the angles mentioned earlier.

Write a function rule that gives the total cost c(p) of p pounds of sugar if each pound costs $0.59.


A. c(p) = p + 0.59

B. c(p) = 59p

C. c(p) = p/0.59

D. c(p) = 0.59p

Answers

Answer:

D. c(p) = 0.59p

Step-by-step explanation:

The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is C(p)=0.59p

The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is,

                                c(p) = ($0.59)p

We multiply the number of pounds of sugar, p, time the cost per pound ,.59, to get the total cost

c(p) = .59*p

Kind of hard to tell what’s a plus and minus sign so maybe some of these are incorrect.

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.
