So you said 20% is xx???
If 20% is xx or x^2 (x squared) then 100% must be 5x^2, since 20% times 5 would get you 100%.

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:

Please can someone please help me

antoniya [11.8K]

Answer:

544 cm²

Step-by-step explanation:

hello,

to find the tsa of a rectangular prism, you use:

tsa = 2 ( lw + lh + wh )

in this case, l = 16 cm, w = 6 cm and h = 8 cm.

knowing these informations, you can proceed with using the formula.

tsa = 2 [ ( 16*6) + ( 16*8 ) + ( 6*8) ]

= 2 [ 96 + 128 + 48 ]

= 2 ( 272 )

= 544 cm²

please try to understand how i worked this out, and do let me know if you have any questions.

have a great day! thank you!
