Answer:

8. $\frac{8r^{2} }{q^{2} }$

10. $12x^{-1} y^{6} z$

Step-by-step explanation:

8. $\frac{16p^{6}qr^{8} }{2(p^{2}qr^{2})^{3} }$ = $\frac{16p^{6}qr^{8} }{2p^{6}q^{3}r^{6} }$ = $\frac{8r^{2} }{q^{2} }$

10. $4x^{2} y$ . 3 $(-2x^{4} y)^{0}$ . $x^{-3} y^{5} z$ = $4x^{2}y$ . $3(1)$ . $\\x^{-3} y^{5}z$ = $\\12x^{-1}yx^{6}z$

A quadrilateral has exactly one right angle and two nonadjacent angles that each measure 105 degrees

LiRa [457]

Answer:

C) Kite

Step-by-step explanation:

The problem states that the polygon is a quadrilateral, meaning it has 4 sides. This rules out D, as pentagons have 5 sides. Our next clue is that this shape has only one right angle, ruling out A and B, because, by definition, rectangles and squares must have four 90 degree angles. We can already see that we are left with only one choice, but to confirm: a kite has 2 opposite angles of 105 degrees, like the problem states.

Therefore, the answer is C) Kite

Hope this helps!

In the pictures down below Can anyone help? Fractions and percents

wariber [46]

1st Picture:
$3)- \frac{6}{7} +\frac {10}{11}
\\\\LCD:77
\\\\\frac{6}{7}* \frac{11}{11} + \frac{10}{11}*\frac{7}{7}= \frac{66}{77} + \frac{70}{77} = \frac{136}{77} = 1\frac{59}{77} 
 \\ \\ 4) 3\frac{6}{7}* 2 \frac{1}{10}= \frac{27}{7} * \frac{21}{10} = \frac{567}{70} =\frac{81}{10} = 8\frac{1}{10}
\\\\5)2\frac{1}{2}+3\frac{1}{3}
\\\\LCD: 6
\\\\ 2\frac{3}{6} + 3\frac{2}{6} =5\frac{5}{6}
\\\\6)5\frac{1}{8}*-6\frac{6}{11}=\frac{41}{8}* \frac{72}{11}=\frac{2952}{88}=\frac{369}{11}=33\frac{6}{11}$

2nd Picture:

$1)80 percent of 80 = .8*80 =64
\\\boxed{64}
\\\\2)95percent of 100=.95*100=95
\\\boxed{95}$
