what is 243.275 in expanded form​

Answer:

The surface area is [tex]379.94in^2[/tex]

Step-by-step explanation:

Given

Shape: Sphere

[tex]D= 11\ in[/tex] - -- Diameter

Required

Determine the surface area (A)

This is calculated using:

[tex]A = 4\pi r^2[/tex]

Where

[tex]r = \frac{1}{2}D[/tex]

[tex]r = \frac{1}{2}*11[/tex]

[tex]r = 5.5[/tex]

So, we have:

[tex]A = 4 * 3.14 * 5.5^2[/tex]

[tex]A = 4 * 3.14 * 30.25[/tex]

[tex]A = 379.94[/tex]

Hence, the surface area is [tex]379.94in^2[/tex]

Answer:

x=-2/3

Step-by-step explanation:

f(x)=9×2/3x+4

0=9×2/3x+4(substitute f (x) =0)

0=9×2/3x+4

0=3×2x+4

0=6x+4

-6x=4( move the variable to left side and change the sign)

Divide both sides.. x=-2/3

The initial value of the function f(x) = [tex]\frac{-2}{3}[/tex]

We have a function f(x) = [tex]9(\frac{2}{3} )x +4[/tex]

We have to find the initial value of the function f(x).

We can calculate the initial value of a function f(x) by equating the function f(x) = 0, and find the value of [tex]x[/tex].

In the question given - f(x) = [tex]9(\frac{2}{3} )x +4[/tex]. In order to calculate the initial value of this function - equate f(x) = 0. Therefore -

[tex]9(\frac{2}{3} )x +4 =0\\[/tex]

6x + 4 = 0

x = [tex]\frac{-4}{6}[/tex]

x = [tex]\frac{-2}{3}[/tex]

Hence, the initial value of the function f(x) = [tex]\frac{-2}{3}[/tex]

Answer:

  C)  2/3

Step-by-step explanation:

In order to answer the question, we must make an assumption about the given figure. We must assume it is a rectangle, so the left side and right side of the figure are the same length.

The ratio of the right side of the figure to the diagonal is sin(a). The ratio of the left side of the figure to the diagonal is cos(b). If we assume that the left and right sides are the same length, then ...

  sin(a) = 2/3 = side/diagonal = cos(b) = 2/3

_____

Additional comments

The figure does not have enough information to support our assumption. Of the answer choices, only (A) is a reasonable alternative. (The value of the cosine must be at most 1.)

The first attachment shows the figure with sin(a) = cos(b) = 2/3. The second attachment shows the figure with cos(b) = 1/3. There is nothing in the given drawing to say this is an incorrect interpretation. (Drawings cannot be assumed to be to scale.)

Answer:

x=2.5

Step-by-step explanation:

Answer:

3.75

Step-by-step explanation:

Volume = length x width x height

             = 2.5 x 1 x 1.5

             = 3.75 cm^3

WE count number of blocks for all values seperately, like

for height its three blocks and one block is equal to 1/2

so.

1/2 x 3= 1.5

Answer:

[tex]y -8= \frac{9}{2}(x +6)[/tex]

Step-by-step explanation:

Given

[tex]f(-6) = 8[/tex]

[tex]f(-8) = -2[/tex]

Required

Determine the equation in point-slope form

The general function notation is:

[tex]f(x) = y[/tex]

So, in  [tex]f(-6) = 8[/tex]

[tex](x_1,y_1) = (-6,8)[/tex]

[tex]f(-8) = -1[/tex]

[tex](x_2,y_2) = (-8,-1)[/tex]

Calculate the slope (m)

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

[tex]m = \frac{-1-8}{-8-(-6)}[/tex]

[tex]m = \frac{-1-8}{-8+6}[/tex]

[tex]m = \frac{-9}{-2}[/tex]

[tex]m = \frac{9}{2}[/tex]

The equation is then calculated as:

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

[tex]y -8= \frac{9}{2}(x - (-6))[/tex]

[tex]y -8= \frac{9}{2}(x +6)[/tex]

[tex]-25 -35=-60[/tex]

Step-by-step explanation:

(a)

[tex]8 - 10[/tex]

Rewrite as addition:

[tex]8 - 10 = 8 + (-10)[/tex]

[tex]8 - 10 = -2[/tex]

(b):

[tex]-20 - 10[/tex]

Rewrite as addition:

[tex]-20 - 10 = -20 + (-10)[/tex]

[tex]-20 - 10 = -30[/tex]

(c)

[tex]-2 - (-19)[/tex]

Rewrite as addition:

[tex]-2 - (-19) = -2 +19[/tex]

[tex]-2 - (-19) = 17[/tex]

Answer:

The length of the lot is 13 feet, and the width is of 5 feet.

Step-by-step explanation:

Perimeter of a rectangle:

The perimeter of a rectangle of length l and width w is given by:

[tex]P = 2(l + w)[/tex]

Lot of 36 feet:

Rectangular, so [tex]P = 36[/tex]

Length 8 feet longer than the width:

This means that [tex]l = 8 + w[/tex]

Finding the width:

[tex]P = 2(l + w)[/tex]

[tex]2(8 + w + w) = 36[/tex]

[tex]16 + 4w = 36[/tex]

[tex]4w = 20[/tex]

[tex]w = \frac{20}{4}[/tex]

[tex]w = 5[/tex]

Finding the length:

[tex]l = 8 + w = 8 + 5 = 13[/tex]

The length of the lot is 13 feet, and the width is of 5 feet.
