makkiz [27]

28.50x + 110.99(14-x)=811.45

distribute

28.50 x + 1553.86-110.99x =811.45

combine like terms

-82.49x+1553.86=811.45

subtract 1553.86 from each side

-82.49x =-742.41

divide by -82.49

x=9

He bought 9 of the 28.50 features and 5 of the 110.99 features

A manufacturer wishes to make a cereal box in the shape of a golden rectangle, based on the theory that this shape is the most p

soldier1979 [14.2K]

Let w be the width and l the length of the rectangle.
Then: $\frac{l}{w}= \frac{1+\sqrt5}{2} \text{ and }lw=104$
Solving the above system we get:
$l= \frac{1+\sqrt5}{2}w\\= \frac{1+\sqrt5}{2}\frac{104}{l}$
Therefore:
$l^2=\frac{1+\sqrt5}{2}104$ then $l=13$ ,which is the length,
And then the width $w=\frac{104}{13}=8$

Since this is an isosceles triangle, the two bottom angles must be equal, while the top angle (in the way this specific triangle is oriented) must be different. Therefore, angle CDB is 63 degrees.
