Solution is given in the 5 attachments above.

Answer 2

Answer:

1.40%

2.c.prt/100

3.b.-7/16

4.40sq.cm

5.πd

1.

$\frac{1}{2} \times base \times height$

2.

$- \frac{5}{9} < \frac{3}{5}$

3.

$= \frac{1}{2 } \times ( - 3 - 2) \\ = \frac{1}{2} \times - 5 \\ = - \ \frac{5}{2} is \: the \: first \: rational \: no \\ = \frac{1}{2 } \times ( \frac{ - 5}{2} - 2) \\ = \frac{1}{2 } \times \frac{ - 9}{2 } \\ = \frac{ - 9}{4} is \: the \: second \: rational \: no \\ = \frac{1}{2} \times ( \frac{ - 9}{4} - 2) \\ = \frac{1}{2} \times \frac{ - 17}{4 } \\ = \frac{ - 17}{8} is \: the \: third \: rational \: no \\ = \frac{1}{2} \times (\frac{ - 17}{8} - 2) \\ = \frac{1}{2} \times \frac{ - 33}{8} \\ = \frac{ - 33}{16} is \: the \: fourth \: rational \: no$

1.

$= (1 - \frac{10}{100} ) \times 120 \\ = \frac{90}{100} \times 120 \\ = 108$

2.

$si = \frac{prt}{100} \\ = \frac{3500 \times 7 \times 2}{100} \\ = 490$

3.

$= \frac{ - 19}{9} - \frac{1}{6} \\ = \frac{ - 38 - 3}{18} \\ = \frac{ - 41}{18}$

4.

$= \frac{1}{2} \times b \times h \\ = \frac{1}{2} \times 12 \times 9 \\ = 6 \times 9 \\ = 54 {cm}^{2}$

5.

$circumference = \pi \: d \\ = \frac{22}{7} \times 14 \\ = 22 \times 2 \\ = 44cm \\ area = \pi \: { \frac{d}{2} }^{2} \\ = \frac{22}{7} \times \frac{14}{2} \times \frac{14}{2 } \\ = 22 \times 7 \\ = 154$
