## Answers:

1- **4**

Underline the tenth place: \(5231.\underline{\\4}8245\) Look to the right if it is 5 or bigger, add 1 to the underlined digit. Then, round up the decimal to 5231.5

2- **20**

\( 75 × \frac{x}{100} = 15 \) ⇒\( 75 × x = 1500 ⇒ x = \frac{1500}{75} = 20\)

3-** 11.48$**

\($44 – $32.52 = $11.48\)

4-** \(\frac{-x-3}{2x^2-10}\)**

\(\frac{\frac{1}{2}-\frac{x+5}{4}}{\frac{x^2}{2}-\frac{5}{2}} =\frac{\frac{1}{2}-\frac{x+5}{4}}{\frac{x^2-5}{2}} = \frac{2(\frac{1}{2}-\frac{x+5}{4})}{x^2-5}\)

⇒Simplify:

\( \frac{1}{2} -\frac{x+5}{4} = \frac{-x-3}{4}\)

\(\frac{2(\frac{-x-3}{4})}{x^2-5} =\frac{\frac{-x-3}{2}}{x^2-5}=\frac{-x-3}{2(x^2-5)}=\frac{-x-3}{2x^2-10}\)

5- **\(–30\)**

Use PEMDAS (order of operation): \( 5 + 8 × (–2) – [4 + 22 ×5] ÷ 6 = 5 + 8 × (–2) – [4 + 110] ÷ 6 = 5 + 8 × (–2) – [114] ÷ 6 = 5 + (–16) – 19 = 5 + (–16) – 19 = –11 – 19 = –30\)

6- **$30**

\(55×$77=$4235\) Payable amount is:\($4265-$4235=$30\)

7- **\( – 3\)**

\(x1,2 = \frac{-b ± \sqrt{(b^2-4ac)} }{2a}\)

\(ax^2 + bx + c = 0\)

\(4x^2 + 14x + 6 = 0\) ⇒then: a = 4, b = 14 and c = 6

\(x = \frac{-14 + \sqrt{14^2 – 4 ,4 ,6} }{2 ,4} = – \frac{1}{2}\)

\(x = \frac{-14 – \sqrt{14^2 – 4 ,4 ,6} }{2 ,4} = – 3\)

8-** \(x^{\frac{ 15}{4}}\)**

\( (x^6)^{\frac{5}{8}} = x^{6 × \frac{5}{8}} = x^{\frac{ 30}{8}} =x^{\frac{ 15}{4}} \)

9- **32**

\(32 + 35 + 29 = 96\)

Average = \( \frac{96}{3} = 32\)

10-** \(45^\circ\)**

\(90^\circ + 45^\circ = 135^\circ\)

\(180^\circ- 135^\circ = 45^\circ\)

11- **\((x – 1)(x + 6)\)**

\( x^2 + 5x – 6 = (x – 1)(x + 6)\)

12-

The relationship among all sides of special right triangle \(30^\circ-60^\circ- 90^\circ\) is provided in this triangle:

13- **5**

\(C = \sqrt{(x_A- x_B)^2 + (y- y_B)^2 ) }\)

\(C = \sqrt{(1-(-2))^2 + (3- 7)^2}\)

\(C = \sqrt{(3)^2 + (- 4)^2 )} \)

\(C = \sqrt{9 + 16}\)

\(C = \sqrt{25} = 5\)

14-** \(0.02857143 \cong 0.0286 \)**

\( \frac{4}{140} = \frac{1}{35} = 0.02857143 \cong 0.0286 \)

15- **\(\frac{20}{3} \)**

\( f(x) = x – \frac{5}{3} ⇒( y = x) (– \frac{5}{3} ) ⇒y+ \frac{5}{3} = x \)

\(f^{-1} = x+ \frac{5}{3} \)

\(f ^{–1}(5) = 5 + \frac{5}{3} = \frac{20}{3} \)

16- **\(\frac{ 1}{4}\)**

Probability \(=\frac{number of desired outcomes}{number of total outcomes} = \frac{18}{12+18+18+24} = \frac{18}{72} =\frac{ 1}{4}\)

17-** \(\frac{\sqrt{3}}{2}\)**

\(cos 30^\circ = \frac{\sqrt{3}}{2}\)

18- **cosθ=\(\frac{4}{5}\)**

sinθ\(=\frac{3}{5}\)⇒ we have following triangle, then \(c=\sqrt{5^2-3^2 }=\sqrt{25-9}=\sqrt{16}=4) \)

cosθ\(=\frac{4}{5}\)

19- **5**

\(|9 – (12 ÷ | 2 – 5 |)| = |(9-(12÷|-3|))|=|9-(12÷3)|=|9-4|=|5|=5\)

20- **\( \frac{16}{x^3 }\)**

\( \frac{x^3}{16 } \) ⇒ reciprocal is :\( \frac{16}{x^3 }\)
