Answer:

He is reasonable to an extent, but he is not. He can saw 8 posts with the given materials.

Step-by-step explanation:

To make 9 posts. He would need 108 inches of material. He can only make 8 posts with the materials he has. With the remainder of the material he could possibly make 6/10ths of a post.

The problem is asking you to move around the vertices of points A, B, and Y. Once you do that, all you have to do is look at each angle measure and record it. Once again, the sum of all interior angles in a triangle should be 180° no matter what.

Answer:

1.

x <   -  \frac{5}{13}

2.

x \geqslant  -  \frac{1}{5}

Step-by-step explanation:

↷

- \frac{13}{16}x +  \frac{3}{8}  <  \frac{11}{16}  \\  \frac{  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  - \frac{3}{8 }    <   -   \frac{3}{8} }{ \frac{  -  \frac{13}{16}x }{   - \frac{13}{16} }   <   \:  \:  \:  \frac{ \frac { 5}{16} }{ -  \frac{ 13}{16} } }   \\  \\ x  <    \frac{ - 5}{ \: 13}

↷

\frac{1}{3}  \geqslant  \frac{2}{9}  -  \frac{5}{9} x \\  \frac{   -  \frac{  2}{9} \geqslant   -   \frac{2}{9} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   }{ \frac{ \:  \:  \:  \frac{1}{9}x }{  - \frac{ 5}{9} } \geqslant   \frac{  - \frac{5}{9} }{  - \frac{5}{9} }   }  \\  \\ x  \geqslant   -  \frac{1}{5}

What is a reasonable estimate for -3/2x (-5 1/4)
Leona [35]

To estimate, you should round some of the numbers to the closest number (rounding up or down).  It will be more accurate the less you round. In this problem, we should round -5 1/4 to -5 since it is the closest. -5*-3/2 = 7.7. You will end up with -3/2x (-5 1/4) ≈ 7.5x

≈ means approximately equal.
