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

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]

Area of the roof = 2(lw)

Area 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

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.

Answer:

[tex]y=2x[/tex]

Step-by-step explanation:

We want to write an equation in slope-intercept form that passes through the points (2, 4) and (3, 6).

So, we will first find the slope. Let (2, 4) be (x₁, y₁) an let (3, 6) be (x₂, y₂).

The slope formula is given by:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

So, by substitution, our slope is:

[tex]\displaystyle m=\frac{6-4}{3-2}=\frac{2}{1}=2[/tex]

Now, we can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

By substitution:

[tex]y-(4)=2(x-(2))[/tex]

Distribute:

[tex]y-4=2x-4[/tex]

Adding 4 to both sides yields:

[tex]y=2x[/tex]

And we have our equation.

In this case, the y-intercept is 0.

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' .

Answer:

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.

Answer: 10 large melons

Step-by-step explanation:

Carl saw 25 melons at a store.

Of these 25, 15 were small and the rest were large.

The number of large melons will have to be the whole total of 25 melons less the number of small melons which is 15:

= 25 total melons - 15 small melons

= 10 large melons
