Question

Номер 7,8 пожалуйста с решением

Answer 1

7.

$V_{1} =8 * 3 * 4 = 96$

$V_{2} = 2 * 2 * 2 = 8$

$V = V_{1} +V_{2} = 96 + 8 = 104$

8.

$\frac{-\frac{55}{24}:\frac{11}{6}+0.48}{-\frac{19}{2}:(\frac{57}{10}-\frac{152}{35})}$=

$=\frac{-\frac{55*6}{24*11}+\frac{48}{100}}{-\frac{19}{2}:\frac{475}{350}}= \frac{-\frac{5}{4}+\frac{48}{100}}{-\frac{19 * 14}{2 * 19}}=\frac{-\frac{125-48}{100}}{-7} =\frac{-\frac{77}{100}}{-7} = \frac{77}{100*7}=\frac{77}{700}=0.11$
