Identify the polygon with vertices H(-6, -2), A (-10,4), T(-6,6), and C(-2,4) and then find the perimeter
and area of the polygon.

Answer:

W=12 cm.

Step-by-step explanation:

If the total area is 180 sq. cm., and you multiply length times width to find area, this time it is inversed. So you do 180/15=12

Answer:

12 cm

Step-by-step explanation:

The area of a rectangle = length × width

We know that the length is 15 cm and the area is 180 cm² so we can substitute this into the equation:

180 cm² = 15 cm × width

Finally, we can divide both sides by 15 to find the width:

width = 180 ÷ 15

width = 12 cm

Answer:

C

Step-by-step explanation:

using the Altitude- on- Hypotenuse theorem

(leg of big Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse )

x² = 20 × (20 + 36) = 20 × 56 = 1120 ( take square root of both sides )

x = [tex]\sqrt{1120}[/tex] = [tex]\sqrt{16(70)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{70}[/tex] = 4[tex]\sqrt{70}[/tex]

, volume = [(3√3)/2]a2h cubic units

Step-by-step explanation:

The formula for the volume of a hexagonal prism is, volume = [(3√3)/2]a2h cubic units where a is the base length and h is the height of the prism.

Answer:

5x+4

Step-by-step explanation:

Combine like terms: 12x+4-7x

Notice that the 7 is being subtracted, as it's negative

12x+4−7x

5x + 4

answer is 5x + 4

The equation that represent the height of the rectangular prism is h = v / lw, where the value of height is 2.5 inches

where

l = length

w = width

h = height

Therefore,

l = 18 inches

w = 6 1 / 2  = 13 / 2 inches

h  =?

v = 292 1 / 2  = 585 / 2

Therefore,

h = v / lw

h = 585 / 2 × 1 / 18 × 2 / 13

h = 585 / 234

h = 2.5 inches

Answer:

Step-by-step explanation:

Area is found by doing two length x width. Because ethics is a square all side lengths are equal. Therefore I did the square root of 625 in order to determine what 2 numbers (length and width) would be multiplied by each other to get 625. Hope this helps

Formula: [tex]A=lw[/tex] where l is the length and w is the width

Whenever we modify any of the side lengths, as in make them longer or shorter, we simply add or subtract from l or w.

When a quadratic equation is organized in standard form, it follows the following format:

[tex]y=ax^2+bx+c[/tex] where a, b and c are numbers

In standard form, all the terms have been simplified and there are no parentheses to expand.

We're given:

If we're expanding each side by x, we're simply adding x to each side length:

10 ft by 10 ft ⇒ (x + 10) ft by (x + 10) ft

Now to find the area, we can use the area formula:

[tex]A=(x+10)(x+10)[/tex]

This expression can be simplified as l = w:

[tex]A=(x+10)^2[/tex]

Putting it into standard form:

We can do this by expanding the parentheses:

[tex]A=(x+10)^2[/tex]

⇒ Because this is a perfect square, we can use the following rule to help us expand this equation:

[tex]A=x^2+20x+100[/tex]

Therefore, the expression in standard form that represents the area of the new expanded garden is [tex]x^2+20x+100[/tex].

Step-by-step explanation:

Find the difference between year 4 and year 5 salary.

32,625 - 31,900 = 725 (rate of change)

Multiply 4 x 725 then subtract that number from 31,900 to find out base salary

4x 724 = 2900

31,900 - 2,900 = 29,000

That's the constant.

So,

From Daniel's initial location from the campsite given the width of the

stream is 400 feet and Daniel swims to the boat ramp, we have;

1.) Please find attached the drawing of the situation

2.) 3.34 minutes

3.) 1,298.59 feet

4.) 3.69 minutes

1.) Please find attached a labelled diagram of the scenario created with MS Visio

2.) Daniel's average swimming rate (speed) = 150 feet per minute

[tex]The \ distance \ Daniel \ swims = \mathbf{\dfrac{400 \, feet}{sin(53^{\circ})}} \approx 500.85 \, feet[/tex]

The time it takes him to swim to the boat ramp, t, is therefore;

3.) The distance, d₁, downstream of the boat ramp from Daniel is given as follows;

d₁ = √((500.85 feet)² - (400 feet)²) ≈ 301.41 feet

Therefore;

The distance from the boat ramp to the campsite, d₂, is therefore;

d₂ ≈ 1600 feet - 301.41 feet = 1,298.59 feet

The distance from the boat ramp to the campsite, d₂ ≈ 1,298.59 feet                              

4. The time, t₂, it will take Daniel to jog from the boat ramp to the campsite is given as follows;

[tex]t_2 = \mathbf{\dfrac{d_2}{v_2}}[/tex]

Where;

v₂ = The rate at which Daniel can jog, which is 4 mph

Which gives;

[tex]t_2 = \mathbf{\dfrac{1298.59 \, feet}{4 \, mph}} = \dfrac{1298.59 \, feet}{4 \, mph} \approx \dfrac{1298.59 \, feet}{5.866142 \ feet/s} \approx \dfrac{221.37 \, s}{60 \, s/min} \approx 3.69 \, min[/tex]
