If AP 10 - 12. What is the perimeter of quadrilateral TAEO (a) 56 (b)64 (c)72 (d)76​

The surface area of the cone is the amount of space on it, the radius of the cone is about 13 feet

The given parameters are:

The surface area is calculated using:

[tex]A =\pi r(r + \sqrt{h^2 + r^2})[/tex]

So, we have:

[tex]A =\pi r(r + \sqrt{(3r)^2 + r^2})[/tex]

Substitute 2167 for A

[tex]2167 =\pi r(r + \sqrt{(3r)^2 + r^2})[/tex]

Evaluate the sum

[tex]2167 =\pi r(r + \sqrt{10r^2})[/tex]

Divide both sides by [tex]\pi[/tex]

[tex]689.78 =r(r + \sqrt{10r^2})[/tex]

Evaluate the exponent

[tex]689.78 =r(r + 3.16r)[/tex]

Evaluate the sum

689.78 =r(4.16r)

Open the bracket

689.78 = 4.16r²

Divide both sides by 4.15

r² =165.8125

Take the square root of both sides

r = 13 (approximated)

Hence, the radius of the cone is about 13 feet

The equation that the given graph of the system of equations solves is: 1/3x + 1 = 2x - 4.

Where m is the slope and b is the y-intercept, the equation of a line in slope-intercept form is expressed as y = mx + b.

Equation of the Blue Line:

Slope (m) = change in y / change in x = 2/1 = 2

y-intercept (b) = -4.

Equation: y = 2x - 4

Equation of the Red Line:

Slope (m) = change in y / change in x = 1/3

y-intercept (b) = 1

Equation: y = 1/3x + 1

The equation that the graph of the systems of equations solve would be: 1/3x + 1 = 2x - 4.

Answer:

m<S = 68 degrees.

m<D = 112 degrees

Step-by-step explanation:

Opposite angles of a parallelogram are equal so:

4x - 4 = 3x + 14      

4x - 3x = 14 + 4

x = 18.

So m < S = 4(18) - 4

= 72-4

= 68 degrees.

Angles on the same side of a parallelogram are supplementary, so

m < D = 180 - 68

= 112 degrees.

Step-by-step explanation:

Answer:

( - 1, - 5)

Step-by-step explanation:

Elimination Method:

Multiply the second equation by -1, then add the equations together.

(3x−4y=17)

−1(7x−4y=13)

Becomes:

3x−4y=17

−7x+4y=−13

Add these equations to eliminate y:

−4x=4

Then solve−4x=4for x:

−4x=4

-4x / -4 = 4/-4 (Divide both sides by -4)

x= −1

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

3x−4y=17

Substitute−1forxin3x−4y=17:

(3)(−1)−4y=17

−4y−3=17(Simplify both sides of the equation)

−4y−3+3=17+3(Add 3 to both sides)

−4y=20

-4y/ -4 = 20/ -4 (Divide both sides by -4)

Answer:

1500 people.

Step-by-step explanation:

100% of the fans are not known,

So let the total number of fans or 100% of the fans be X

SINCE 10% ••••••••••• 150

100% ••••••••••••X

we're going to Cross multiply

= 10×X = 100 × 150

10X = 15000

dividing bothsides by 10

10X/10 = 15000/10

X = 1500 people.

Step-by-step explanation:

calculate the slope m of the 2 points from the origin and equate, since they lie on the same line

m = [tex]\frac{y_{2}-y_{1} }{x_{2-x_{1} } }[/tex]

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (2, k )

m = [tex]\frac{k-0}{2-0}[/tex] = [tex]\frac{k}{2}[/tex]

repeat with

(x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = k, 32 )

m = [tex]\frac{32-0}{k-0}[/tex] = [tex]\frac{32}{k}[/tex]

equating the 2 slopes

[tex]\frac{k}{2}[/tex] = [tex]\frac{32}{k}[/tex] ( cross- multiply )

k² = 64 ( take square root of both sides )

k = [tex]\sqrt{64}[/tex] = 8

The slope as evaluated from the given pair of points is; Slope, m = 5.

Slope of given Points

The slope of a line defined by two points simply refers to the rate of change of the function given by the line.

Hence, slope, m = (28 -18)/(4 -2)

Slope, m = 10/2

Slope, m = 5

(1) ⇒ 2x - y = 1 ⇒ y = 2x - 1 = 2(-1) - 1 = -3

Answer:

y = 1/3*x -3

Step-by-step explanation:

Method 1:

Grab two random points from the line.

(0,-3) and (3,-2)

Using the Point-Slope Form solve for m.

(-3 - (-2)) = m * (0 - (3))

-1 = m * (-3)

m = 1/3

Turning Point-Slope form into Slope intercept Form.

(y - (-3)) = 1/3 * (x - 0)

y + 3 = 1/3x

y = 1/3 - 3

Method 2:

Look at the y-intercept since y-int becomes our b. b = -3

From the y-int count rise/run as thats our Slope m. m = 1/3

Slope-intecept Form:

y = 1/3*x -3

Answer:

y=1/3x-3

rise/run= 1/3

well, the shape is a trapezoid, a trapezoid has two parallel sides only, the parallel sides are called "bases", and the distance between the parallel sides is its "height".

The estimate that 2.8 million square feet of the building is used for office space is not reasonable

From the plan, the width of the building is:

Width = 230 feet

The building has a circular area, and it has four floors

So, the estimate of the building area is:

Area= 4πR²

So, we have:

Area= 4 * 3.14 * 230²

Evaluate

Area= 664424

The above value cannot be approximated to 2.8 million

The age of Marissa and her younger brother.

We know that the older brother's age is 18 and he is twice older than the younger brother.

Let the unknown be "x"

[tex] x=\frac{18}{2} [/tex]

[tex]\large\boxed{\sf{x=9 \: years}}[/tex]

Now, we know that the younger brother's age is 9 and Marissa is 3 years older than him.

Let the unknown be "x"

[tex]x=9 + 3[/tex]

[tex]\large\boxed{\sf{x=12 \: years}}[/tex]

Therefore, Marissa is 12 and her younger brother is 9

Answer:

Marissa's age = 12

Younger brother's age = 9

Step-by-step explanation:

Let age of Marissa be x, and her younger brother's y.

Equations formed :

Finding age of younger brother using Equation 2 :

⇒ 2y = 18

⇒ 2y/2 = 18/2

⇒ y = 9 years old

Substituting y in Equation 1 :

⇒ x = y + 3

⇒ x = 9 + 3

⇒ x = 12 years old

Marissa's age = 12

Younger brother's age = 9
