Answer:

The cost of renting will be the same for 200 miles.

Step-by-step explanation:

Let n the number of miles and C be the cost. We can represent the cost equations for each companies:

A: C = 12 + 0.09n

B: C = 8 + 0.11n

They want to know when the cost will be the same, so we can set the above 2 equations equal to each other and solve for n:

12 + 0.09n = 8 + 0.11n

0.02n = 4

n = 200

The first one is 8/12.

Step-by-step explanation:Add numerator and keep denominator same.

Answer:

5/12 + 3/12

Step-by-step explanation:

[tex]\frac{5}{12} + \frac{3}{12} = \frac{8}{12}[/tex]

This is because when adding fractions with the same denominator, you just add the numerators.

The other answer choices do not equal 8/12...

[tex]\frac{2}{4} + \frac{3}{4} + \frac{3}{4} = \frac{8}{4} = 2[/tex]

[tex]\frac{2}{3} + \frac{3}{4} + \frac{3}{5} = \frac{40}{60} + \frac{45}{60} + \frac{36}{60} = \frac{121}{60} = 2 \frac{1}{60}[/tex]

[tex]\frac{4}{6} + \frac{4}{6} = \frac{8}{6} = \frac{4}{3} = 1 \frac{1}{3}[/tex]

Answer:

x = 3

y = 8

Step-by-step explanation:

y = x + 5

y = 2x + 2

They both equal y, so:

x + 5 = 2x + 2

x + 3 = 2x

3 = x

Put the value of x into the equations:

y = 3 + 5 = 8

y = 2(3) + 2 = 8

x = 3

y = 8

This graph is a circle. The general equation for a circle is x² + y² = r², where r is the radius. In this case, the radius is 3 because √9 = 3. Also, the center is (0,0) because the circle is not translated. Therefore, the graph is a circle with center (0,0) and radius 3. If you still need help, the y-intercepts are (0,±3) and the x-intercepts are (±3,0). Hope this makes sense!

Step-by-step explanation:

Using exponential function concepts, it is found that the range of the function after it has been reflected over the x-axis is given by:

all real numbers less than 0.

It is modeled by:

[tex]y = ab^x + c[/tex]

In which:

In this problem, a reflection over the x-axis means that it was multiplied by -1, hence the range will be (-infinity, 0), hence the correct option is;

Answer:

The painter paint the room by himself in 12h.

Step-by-step explanation:

If we consider that the room is the distance that the painter and his friend need to paint, then each person will have a painting speed and if we sum them they will finish the room in 8 hours. If we call the speed of the painter "x" and the his time "tx", while his friend will be "y" and his time will be "ty". We can apply each case to the average speed formula:

Both working together:

speed = distance / time

x + y = room / 8

The friend alone:

y = room / ty

The painter alone:

x = room / tx

Therefore:

(room/tx) + (room/ty) = room/8

1/tx + 1/ty = 1/8

(tx + ty)/tx*ty = 1/8

8*tx + 8*ty  = tx*ty

Since tx = ty - 12, we have:

8*ty - 96 + 8*ty = ty² - 12*ty

ty² - 12*ty - 16*ty + 96 = 0

ty² - 28*ty + 96 = 0

ty = 4 or ty = 24

Since tx = ty - 12, ty can only be 24, because if it was 4, then the painter time would be negative and that is impossible. So we have:

ty = 24

tx = 24 - 12 = 12

The painter paint the room by himself in 12h.

The painter to paint the room by himself in 12 hours

Let

Friend

x = room / time taken

Painter

y = room / time taken

painter and friend

x + y = room / 8

(room/friend time ) + (room/painter time) = room/8

1/friend time + 1/painter time = 1/8

(friend time + painter time)/friend time × painter time = 1/8

8 × friend time + 8 × painter time =friend time × painter time

Since friend time = painter time - 12, we have:

8 × painter time - 96 + 8 × painter time = painter time² - 12 × painter time

Painter time² - 12 × painter time - 16 × painter time + 96 = 0

painter time² - 28 × painter time + 96 = 0

Pt = 4 or = 24

Since friend time = painter time - 12,

Painter can is 24, because if it is 4, then the painter time would be negative and that is impossible.

So,

Painter = 24

Friend time = 24 - 12 = 12

Therefore, the painter paint the room by himself in 12 hours

Step-by-step explanation:

Answer:

p = - 11, p = 3

Step-by-step explanation:

Given

p² + 8p - 33 = 0 ( add 33 to both sides )

p² + 8p = 33

To complete the square

add ( half the coefficient of the p- term )² to both sides

p² + 2(4)p + 16 = 33 + 16

(p + 4)² = 49 ( take the square root of both sides )

p + 4 = ± [tex]\sqrt{49}[/tex] = ± 7 ( subtract 4 from both sides )

p = - 4 ± 7

Thus

p = - 4 - 7 = - 11

p = - 4 + 7 = 3

Step-by-step explanation:

The surface area of the composite figure is 333 sq. in.

The correct answer is an option (2) 333 in²

"It is a three-dimensional geometric shape with a polygon as its base and the lateral surfaces as triangles which meet at a common point."

"It is a three-dimensional geometric structure which has six faces that are rectangles."

"A figure that consists of two or more geometric shapes."

A = length × width

A = 1/2 × base × height

For given example,

A rectangular prism and a square pyramid were joined to form a composite figure.

The composite figure would have nine faces with four triangular faces and five rectangular faces.

Surface area of the composite figure would be the sum of surface area of  all nine faces.

The dimensions of the rectangular base the composite figure are length of 9 inches, width of 9 inches.

Using the formula for an area of the rectangle,

⇒ A1 = 9 × 9

⇒ A1 = 81 square inches

The surface area of the larger vertical rectangular faces is same.

So, A2 = 2 × (area of the larger vertical rectangular faces)

The dimensions of the larger vertical rectangular faces 9 inches × 5 inches.

⇒ A2 = 2 × (9 × 5)

⇒ A2 = 2 × 45

⇒ A2 = 90 square inches

Similarly, the surface area of the smaller vertical rectangular faces is same.

So, A3 = 2 × (area of the smaller vertical rectangular faces)

The dimensions of the smaller vertical rectangular faces 9 inches × 5 inches

⇒ A3 = 2 × (9 × 5)

⇒ A3 = 2 × 45

⇒ A3 = 90 square inches

The four triangular faces are identical.

Let A4 be the total surface area of four triangular faces.

⇒ A4 = 4 × (area of triangular face)

⇒ A4 = 4 × (1/2 × base × height)

⇒ A4 = 4 × (1/2 × 9 × 4)

⇒ A4 = 4 × 18

⇒ A4 = 72 square inches

So, the surface area of the composite figure is,

⇒ A = A1 + A2 + A3 + A4

⇒ A =  81 + 90 + 90 + 72

⇒ A = 333 sq. in.

Therefore, the surface area of the composite figure is 333 sq. in.

The correct answer is an option (2) 333 in²

Answer

the answer is b. im not sure though

Step-by-step explanation:

1042 square inches is the total surface area of composite solids.

It is clear from the image that the resulting composite solid is a cuboid.

whose sides are as follows

Across the length, there are 3 blocks along the side of 7 inches each.

[tex]Length = 7 \times 3 = 21\ inch[/tex]

Width = 5 inch

Across the height, there are 4 blocks along the side of 4 inches each.

[tex]Height = 4 \times 4 = 16\ inch[/tex]

[tex]\text{Total Surface Area = } 2 (l\times w+ w \times h+ h \times l)[/tex]

We know that the total surface area of a cuboid is,

[tex]\text{Total Surface Area = } 2 (l\times w+ w \times h+ h \times l)\Rightarrow 2 (21 \times 5 + 16 \times 21 + 16 \times 5 )\\\Rightarrow 2 (105 + 336+80)\\\Rightarrow 2 \times 521\\\Rightarrow 1024[/tex]

Therefore, the total surface area = 1024 square inches.
