A model of Steven’s house is shown in the diagram. He is replacing the roof, which consists of two rectangular surfaces. The diagram shows one side of the roof, with the other side hidden from view. What is the total area of the roof to the nearest square foot?
Answers
Answer:
Option B
Step-by-step explanation:
From the picture attached,
Area of the one side of the roof = Area of the rectangle
= Length × Width
= AE × AC
To get the length of side AC, construct a perpendicular AD on side BC which divides BC in two equal parts.
BD = DC = 13 ft
By applying cosine rule in ΔADC,
cos(45)° = [tex]\frac{\text{DC}}{\text{AC}}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{13}{\text{AC}}[/tex]
AC = 13√2
AC = 18.38 ft
Therefore, area of one side of the roof = 38 × 18.38
= 698.62 square feet
Area of both the sides of the roof = 698.62 × 2
= 1397.24 feet²
≈ 1397 feet²
Option B will be the answer.
The total area of the roof to the nearest square foot is 1,397 square feet
Area of composite shapes.In order to get the area of the roof, we will need the slant height of the triangle.
Using the pythagoras theorem;
[tex]cos45 = \frac{26/2}{l} \\cos 45 = \frac{13}{l} \\0.7071 = \frac{13}{l} \\l = \frac{13}{0.7071} \\l=18.39 feet[/tex]
Get the area of the roofArea of the roof = 2(lw)
l is the length of the rectangle = 38ftw is the width = 18.39 feetArea of the roof = 2(38 * 18.39)
Area of the roof = 1,397.64
Area of the roof ≈ 1,397 square feet
Hence the total area of the roof to the nearest square foot is 1,397 square feet

Brianna wants to buy a digital camera for a photography class. One store offers the camera for $49 down
and a payment plan of $20 per month. The payment plan for a second store is described by y - 15x + 79,
where y is the total cost in dollars and x is the number of months. Which camera is cheaper when the
camera is paid off in 12 months? Complete the explanation.
Answers
Answer:
Step-by-step explanation:
Cost of the camera at one store,
Down payment = $49
Per month payment = $20
Duration of the payment = 12 months
Total payment to be done = down payment + payments to be done in 12 months
= 49 + (20×12)
= 49 + 240
= $289
Cost of the camera at second store,
Equation describing the payment plan,
y = 15x + 79
Here, x = number of months
y = Total amount to be paid
If x = 12 months
y = (15×12) + 79
y = 180 + 79
y = $259
The camera at the second store is cheaper when the camera is paid off in 12 months because the cost at the first store is $289 and the cost at the second store is $259.

Step-by-step explanation:
Look at the graph they gave you. ... At first it looks like an ugly mess.
But look closer. There are only two lines there that go through the origin,
so one of those is the answer to the question.
Now let's talk about the slope of a line.
-- If the slope of a line is positive, that means it rises as it goes.
If you walk the graph from left to right, you're climbing.
-- If the slope of a line is negative, that means it falls as it goes.
If you walk the graph from left to right, you're going down-hill.
The equation they gave you is [ y = 1/2 x ].
The slope is 1/2 . That's positive.
The line on the graph slopes up. To walk it, you have to climb.
In the picture, that can only be line 'c' .

A circle with center B and radius 1cm has three distinct points, F, D and E, on its circumference so that BF and BE and D is on the minor arc FE. Point A is on BF so that DA and BF. The point C is on BE so that ABCD is a rectangle and the distance from C to E is 1cm. Determine the distance from A to F.
Answers
Answer:
8 cm
Step-by-step explanation:
A circle with center B and radius 13 cm has three distinct points, F, D and E, on its circumference so that BF and BE and D is on the minor arc FE. Point A is on BF so that DA is perpendicular to BF. The point C is on BE so that ABCD is a rectangle and the distance from C to E is 1cm. Determine the distance from A to F.
Solution:
Since the radius of the circle is 13 cm, hence:
BF = BD = BE = 13 cm.
For line segment BE; BE = BC + CE
BE = BC + CE
13 = BC + 1
BC = 13 - 1
BC = 12 cm
AD = BC = 12 cm (opposite sides of a rectangle are equal to each other)
Triangle ABD, is a right angled triangle because ∠B = 90°. We can use Pythagoras theorem to find AB:
BD² = AB² + AD²
13² = AB² + 12²
169 = AB² + 144
AB² = 169 - 144
AB² = 25
AB = √25 = 5
For line segment BF, we can use the line segment addition postulate to find the distance from A to F. Let x be the distance from A to F:
BF = AB + x
x = BF - AB
x = 13 - 5
x = 8 cm
