Answer:

x=25

Step-by-step explanation:

Multiply both sides by 25

1 x 25=x

Simplify 1x 25125 to 25

switch sides:

x=25

Given the midpoint and one endpoint of a line segment , find the other endpoint. Endpoint: (10, 12), midpoint: (6, 9)

aleksandr82 [10.1K]

The other end-point is: (2,6)

Step-by-step explanation:

Let the end-points be:

$(x_1,y_1)\ and\ (x_2,y_2)$

(x1,y1) = (10,12)

Mid-point = M = (6,9)

The formula for mid-point is given by:

$M(x,y) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Putting the values

$(6,9) = (\frac{10+x_2}{2} , \frac{12+y_2}{2})$

Putting respective coordinates equal

$6 = \frac{10+x_2}{2}\\6*2 = 10+x_2\\12 = 10+x_2\\x_2 = 12-10\\x_2 = 2\\9 = \frac{12+y_2}{2}\\9*2 = 12+y_2\\18 = 12+y_2\\y_2 = 18-12\\y_2 = 6$

The other end-point is: (2,6)

Match the value to the correct image. Not all values will be used.

The <em>approximate surface</em> areas of corresponding prisms are listed below:

<em>A = 108 units²</em>
<em>A = 229 units²</em>
<em>A = 454 units²</em>

<h3>How to match given surface areas with given figures</h3>

The <em>surface</em> area of the each figure ( $A$ ), in square units, is equal to the sum of the <em>surface</em> area of the two bases ( $A_{b}$ ), in square units, and the <em>surface</em> areas of the <em>lateral</em> sides ( $A_{l}$ ), in square units. Since bases are <em>regular</em> polygons, <em>base surface</em> area can be determined by this expression:

$A_{b} = \frac{l^{2}\cdot n }{4\cdot \tan \frac{180}{n} }$ (1)

Where:

<em>l</em> - Side length, in units
<em>n</em> - Number of sides

The area of one lateral side is expressed by this expression:

$A_{l} =h\cdot l$ (2)

Where <em>h</em> is the height of the rectangle, in units.

The total surface area is defined by the following formula:

$A = 2\cdot A_{b} + n\cdot A_{l}$ (3)

Now we proceed to calculate each surface area:

<h3>Case I ( $l = 2$ , $n = 6$ , $h = 9$ )</h3>

$A = 2\cdot \left[\frac{2^{2}\cdot (6)}{4\cdot \tan \left(\frac{180}{6} \right)} \right]+6\cdot (2)\cdot (9)$

<em>A = 108.136 units²</em>

<h3>Case II ( $l = 4\sqrt{3}$ , $n = 3$ , $h = 9$ )</h3>

$A = 2\cdot \left[\frac{(4\sqrt{3})^{2}\cdot (3)}{4\cdot \tan \left(\frac{180}{3} \right)} \right]+3\cdot (4\sqrt{3})\cdot (9)$

<em>A = 228.631 units²</em>

<h3>Case III ( $l = 6$ , $n = 5$ , $h = 11$ )</h3>

$A = 2\cdot \left[\frac{6^{2}\cdot (5)}{4\cdot \tan \left(\frac{180}{5} \right)} \right]+5\cdot (6)\cdot (11)$

<em>A = 453.874 units²</em>

The <em>approximate surface</em> areas of corresponding prisms are listed below:

<em>A = 108 units²</em>
<em>A = 229 units²</em>
<em>A = 454 units²</em>

Answer:

384

Step-by-step explanation:

v= L x W x H

v= 4 x 2 x 1.2

v= 9.6

9.6 x 40 = 384
