Find the coordinates of H if X(-8, 4) is the midpoint of GH and G(2, -9).

skelet666 [1.2K]

Step-by-step explanation:

Hey there!

The given midpoint is; X(-8,4) and G(2,-9).

To find: H

Now; You need to use formula for midpoint.

$midpoint(x) = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

Put all values.

$( - 8,4) = (\frac{ 2 + x}{2} , \frac{ - 9 + y}{2} )$

As they are equal, their corresponding elements are equal.

$- 8 = \frac{2 + x}{2}$

$- 16 - 2 = x$

x = -18

$4 = \frac{ - 9 + y}{2}$

$4 \times 2 = - 9 + y$

$8 + 9 = y$

$y = 17$

Therefore, y = 17.

Therefore, H =( -18,17).

Hope it helps....

Here are 56 trees in an apple orchard. They are arranged in equal rows. There are 8 trees in each row. How many rows of apple tr

vlada-n [284]

There would be 7 rows..
let x be the no.of trees and let y be the no. of rows.....
Sol.
xy=56
8y=56
8y/8=56/8 ---divide both sides by 8 to find y
y=7...so there were 7 rows with 8 apple trees each row...

Hexagonal tiles of side 20 cm are used to tile a room which measures 6.25 m by 4.85 m. Assuming we complete the edges by cutting

ch4aika [34]

Answer: 292 tiles

Step-by-step explanation:

To find the number of tiles needed , we need to know the area of the hexagonal tiles and also the area of the room.

Area of hexagon

The area of hexagon is given as :

Area = $\frac{3\sqrt{3}}{2}$ $a^{2}$

Where a is the length of side.

Therefore:

A = $\frac{3\sqrt{3}}{2}$ $20^{2}$

A = $\frac{3\sqrt{3}}{2}$ X 400

A = (400 x 3 x $\sqrt{3}$ ) / 2

A = $\frac{2078.460969}{2}$

A = 1039.23 $cm^{2}$

Also to find the area of the room , we must first convert from m to cm

6.25 m = 6.25 x 100 cm

6.25m = 625 cm

4.85m = 485cm

Therefore: Area of the room = length x breadth

Area = 625 x 485

Area = 303125 $cm^{2}$

Therefore , the number of tiles needed = area of the room / area of hexagon

Number of tiles = 303125/ 1039.23

N = 291.6823032

Therefore , the number of tiles needed ≈ 292
