ABCDEFGH is a regular octagon. The minimum degree of rotation by which this octagon can map onto itself is

evablogger [386]

The regular octagon has rotational symmetry. Since it is comprised of 8 "equal parts", divide 360º/8 to determine the smallest angle of rotation. 360º/8 = 45º.

A wall shaped like a trapezoid needs to be painted. the height of the wall is 16 feet and the bases are 20 feet and 24 feet. if

AURORKA [14]

Area of Trapezoid = h(b1+b2/2)
b1 and b2 are the lengths of each base and h is the height.

Area = 16(20+24/2)=352 Square Feet

352/20=17.6 Cans of paint.

Hope this helps and is correct, I haven't done this kind of math in a while.

108x25^2divided by 2^6 x 5^2

My name is Ann [436]

Answer:

108 x 25² divided by 2⁶ x 5² is equal to $42\frac{3}{16}$

Step-by-step explanation:

Given;

108 x 25² divided by 2⁶ x 5²

The expression is simplified as follows;

$\frac{108\times 25^2}{2^6 \times 5^2} = \frac{108\times 625}{64\times25} =\frac{675}{16} = 42\frac{3}{16}$

Therefore, 108 x 25² divided by 2⁶ x 5² is equal to $42\frac{3}{16}$

Solve the system of linear equations by elimination. 9x−2y=34 5x+2y=−6

slava [35]

Answer:

x = 2

y = -8

Step-by-step explanation:

9x−2y=34 -------------------(I)

5x+2y=−6 -------------------(II)

Add equation (I) & (II) and so y will be eliminated and we could find the value of x.

(I) 9x - 2y = 34

(II) 5x + 2y = -6 {add}

14x = 28

x = 28/14

x = 2

Plug in x = 2 in equation (I)

9*2 - 2y = 34

18 - 2y = 34

-2y = 34 - 18

-2y = 16

y = 16/-2

y = -8
