find the area of the hexagon with a perimeter of 240

Answer:

33.10

Step-by-step explanation:

Answer:

3300 m²

Step-by-step explanation:

Area of a triangle = 1/2 x base x height

⇒ area of one triangle = 1/2 x 30 x 40 = 600 m²

Area of a square = side length x side length

⇒ area of the square = 30 x 30 = 900 m²

Surface area of square-base pyramid = area of 4 triangles + area of square

⇒ SA = 4 × 600 + 900 = 2400 + 900 = 3300 m²

Answer:

m = -1

Step-by-step explanation:

[tex]m = - (4 + m)[/tex]

Use - to open the bracket

[tex]m = - 4 - m + 2[/tex]

Collect like terms and simplify

[tex]m + m = - 4 + 2 \\ 2m = - 2[/tex]

Divide both sides of the equation by 2

[tex] \frac{2m}{2} = \frac{ - 2}{2} [/tex]

Simplify

[tex]m = - 1[/tex]

Step-by-step explanation:

The linear equation that represents how many more hours Kelley must work to afford the phone is 3x - 45 = 0

Functions are expressions represented in terms of a variable.

From the question, we have the following

Total number of hours = 45

If she works 3 hours per day and has worked x days, the total number of hours she needs to work is 3x

Equating to the total hours wwill give:

3x = 45

3x - 45 = 0

Hence  the linear equation that represents how many more hours Kelley must work to afford the phone is 3x - 45 = 0

Step-by-step explanation:

The dilated cone's with surface area of 2,250π in^2 has a volume of about 12500π in³

Dilation is the increase or decrease in the size of a figure.

The cone has surface area 360π in² and volume 800π in^3. the cone is dilated, and the surface area of the dilated cone is 2,250π in^2.

Hence:

Scale factor² = dilated cone area / cone surface area

scale factor² = 2250π / 360π

Scale factor = 2.5

Volume of dilated cone = 2.5³ × 800π = 12500π in³

The dilated cone's with surface area of 2,250π in^2 has a volume of about 12500π in³

Incomplete questions. Here's the complete question:

Alexandra made a tally chart shown below. A 2-column table with 5 rows. Column 1 is labeled Books Read in the Last Month with entries 1, 2, 3, 4, 5. Column 2 is labeled Tally with entries 2, 5, 3, 1, 2.

Which would be a good statistical question based on the tally chart?

Answer:

How many books did you read in the last month?

Step-by-step explanation:

A tally chart is a numbering system used to quickly record data. It usually involves filling a chart with vertical dashes that represents the number of times an action or information is observed.

Therefore, by asking, "How many books did you read in the last month?", Alexandra would be able to get the answer by means of a tally chart which would show the number of times that action occurred.

Answer:

615.44

Step-by-step explanation:

If the diameter is 28, that means the radius is 14.

The formula for the area of a circle is pi x radius to the power of 2. So, 14 to the power of 2 (or 14 x 14) equals 196. 196 x 3.14 (pi) = 615.44

The estimated area of the circle is about 615.44 cm² or 616 cm², depending on which value you use for π.

Suppose the circle has radius of 'r' units, then, its area is given as:

[tex]A = \pi \times r^2[/tex] sq. units

Since radius of a circle is half of its diameter, so if diameter is of 'd' length, then r= d/2, thus, area can be rewritten as:

[tex]\pi \times (\dfrac{d}{2})^2[/tex] sq. units

We are given that;

Diameter=28cm

Now,

In this case, the diameter of the circle is 28 cm, so the radius is half of that:

r = 28 / 2 = 14 cm

Plugging this value into the formula, we get:

A = π × 14²

Now we can use either 3.14 or 22/7 for π. Let’s use both and compare:

A ≈ 3.14 × 14² ≈ 3.14 × 196 ≈ 615.44 cm²

Or

A ≈ (22/7) × 14² ≈ (22/7) × 196 ≈ (4312/7) cm² ≈ 616 cm²

Therefore, by the area of circle the answer will be 615.44 cm² or 616 cm², depending on which value you use for π.

The slope of the line that passes through the points (1, -2) and (3, -5) is -3/2.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We need to find slope of line passing through the points (1, -2) and (3, -5)

m= -5-(-2)/3-1

=-5+2/2

=-3/2

Hence, the slope of the line that passes through the points (1, -2) and (3, -5) is -3/2.

Given:

6 gallons of light green paint uses [tex]\dfrac{3}{8}[/tex] gallon of white paint.

Liam has [tex]\dfrac{9}{16}[/tex] gallon of white paint.

To find:

Whether Liam have enough white paint to make 8 gallons of light green paint.

Solution:

Here, 6 gallons of light green uses [tex]\dfrac{3}{8}[/tex] gallon of white paint.

So, the white paint for 1 gallon of light green [tex]=\dfrac{\dfrac{3}{8}}{6}[/tex]

                                                                          [tex]=dfrac{3}{8\times 6}[/tex]

                                                                          [tex]=\dfrac{3}{48}[/tex]

                                                                          [tex]=\dfrac{1}{16}[/tex]

It means, 1 gallons of light green uses [tex]\dfrac{1}{16}[/tex] gallon of white paint.

White paint for 8 gallon of light green [tex]=8\times \dfrac{1}{16}[/tex]

                                                               [tex]=\dfrac{8}{16}[/tex]

She has [tex]\dfrac{9}{16}[/tex] gallon of white paint, which is greater than  [tex]=\dfrac{8}{16}[/tex] gallons.

Therefore, Liam have enough white paint to make 8 gallons of light green paint.

If Liam has 9/16 gallon, he has enough white paint to make 8 gallons of light green paint

Given that 6 gallons of light green paint use 3/8 gallon of white paint, this can be expressed as:

3/8 gallons of white paint = 6 gallons of light green

We are to determine if 9/16 gallons will be enough to make 8 gallons of light green paint. This can be expressed as

9/16 gallons of white paint = x

Divide both expressions

3/8 * 16/9 = 6/x

2/3 = 6/x

Cross multiply

2x = 3 * 6

2x = 18

x = 18/2

x = 9

This shows that if Liam has 9/16 gallon, he has enough white paint to make 8 gallons of light green paint
