Kurt is building a rectangular deck. if the dimensions of the deck are 10 ft by 23 ft, what the length of the diagonal of the de

OverLord2011 [107]

The length of the diagonal of the deck can solved using the pythagorean theorem because the diagonal the sides of a rectangle will form a right triangle. pythagorean theorem states that
C^2 = B^2 + A^2
where C is the hypotenuse or the diagonal of the rectangles
B and A are the sides of the rectangle

C^2 = 10^2 + 23^3
C^2 = 629
C = 25.08 ft

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \: x < -2 \:\: or \:\; x >4$

____________________________________

$\large \tt Solution \: :$

$\textsf{First Inequality :}$

$\qquad \tt \rightarrow \: - 2(x + 8) + 6 > x - 4$

$\qquad \tt \rightarrow \: - 2x - 16 + 6 > x - 4$

$\qquad \tt \rightarrow \: - 2x - 10 > x - 4$

$\qquad \tt \rightarrow \: - 10 + 4 > x + 2x$

$\qquad \tt \rightarrow \: - 6 > 3x$

$\qquad \tt \rightarrow \: - \cfrac{ 6}{3} > x$

$\qquad \tt \rightarrow \: - 2 > x$

$\qquad \tt \rightarrow \: \therefore x < - 2$

$\textsf{Second Inequality :}$

$\qquad \tt \rightarrow \: - 3x + 12 < 6(x - 4)$

$\qquad \tt \rightarrow \: - 3x + 12 < 6x - 24$

$\qquad \tt \rightarrow \: 12 + 24 < 6x + 3x$

$\qquad \tt \rightarrow \: 36 < 9x$

$\qquad \tt \rightarrow \: \cfrac{36}{9} < x$

$\qquad \tt \rightarrow \: 4 < x$

$\qquad \tt \rightarrow \: \therefore x > 4$

The area of the track will be 78501 m². The area of the track is equal to the area of the circle.

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square meters and other similar units are used to measure area.

The area of the track is found as;

$\rm A=\frac{\pi}{4} d^2 \\\\ \rm A=\frac{3.14}{4} (100)^2 \\\\ A=7850 \ m^2$

Hence, the area of the track will be 78501 m².
