## Answers:

1- **D**

The equation of a line in slope intercept form is:\( y=mx+b\)

Solve for \(y\).

\(4x-2y=12 {\Rightarrow} -2y=12-4x {\Rightarrow} y=(12-4x){\div}(-2) {\Rightarrow} y=2x-6\)

The slope of this line is 2.

The product of the slopes of two perpendicular lines is\( -1\).

Therefore, the slope of a line that is perpendicular to this line is:

\(m_{1} {\times} m_{2} = -1 {\Rightarrow} 2 {\times} m_{2} = -1 {\Rightarrow} m_{2} = \frac{-1}{2}\)

2- **28**

Let\( x\) be the width of the rectangle. Use Pythagorean Theorem:

\(a^2 + b^2 = c^2\)

\(x^2 + 8^2 = 10^2 {\Rightarrow} x^2 + 64 = 100 {\Rightarrow} x^2 = 100 – 64 = 36 ⇒ x = 6\)

Perimeter of the rectangle =\( 2 (length + width) = 2 (8 + 6) = 2 (14) = 28\)

3-** B**

Let \(x\) be the number of cans. Write the proportion and solve for \(x\).

\(\frac{5 \space cans}{$ 3.40}=\frac{35 \space cans}{x}\)

\(x =\frac{3.40×35}{5}⇒x=$23.8\)

4- **A**

\(2x+4>11x-12.5-3.5x\)→ Combine like terms:

\(2x+4>7.5x-12.5→\) Subtract \(2x\) from both sides: \(4>5.5x-12.5\)

Add 12.5 on both sides of the inequality.

\(16.5>5.5x, \)

Divide both sides by 5.5.

\(\frac{16.5}{5}>x→x<3\)

5- **97.6**

Area of a square: \(S = a^2 ⇒ 595.36 = a^2 ⇒ a = 24.4\)

Perimeter of a square: \(P = 4a ⇒ P = 4 × 24.4 ⇒ P = 97.6\)

6- **A**

Write the proportion and solve for the missing number.

\(\frac{32}{12}=\frac{6}{x}→ 32x=6×12=72 \)

\(32x=72→x=\frac{72}{32}=2.25\)

7- **130**

The perimeter of the trapezoid is 54 cm.

Therefore, the missing side (high) is \( 54 – 18 – 12 – 14 = 10\)

Area of a trapezoid: \(A = \frac{1}{2} h (b_1 + b_2) = \frac{1}{2} (10) (12 + 14) = 130\)

8- **C**

A graph represents \(y\) as a function of \(x\) if

\(x_1=x_2→y_1=y_2 \)

In choice C, for each \(x\), we have two different values for \(y\).

9- **A**

\(13<-3x-2<22\)→ Add 2 to all sides. \(13+2<-3x-2+2<22+2\)

\(→15<-3x<24\)→ Divide all sides by \(- 3\). (Remember that when you divide all sides of an inequality by a negative number, the inequality sign will be swapped. < becomes >)

\(\frac{15}{-3} > \frac{-3x}{3} >\frac{24}{-3} \)

\(-8 < x < -5\)

10- **B**

Number of biology books: 35

Total number of books; \(35+95+80=210\)

The ratio of the number of biology books to the total number of books is: \(\frac{35}{210}=\frac{1}{6}\)

11- **B**

Use a simple interest formula:

I=prt

(I = interest, p = principal, r = rate, t = time)

\(I=(12000)(0.035)(2)=840\)

12- **B**

Use the formula for the area of circles.

Area \(= πr^2 ⇒ 64 π = πr^2 ⇒ 64 = r^2 ⇒ r = 8\)

The radius of the circle is 8. Now, use the circumference formula:

Circumference\( = 2πr = 2π (8) = 16 π\)

13- **D**

To find the discount, multiply the number by (\(100\% –\) rate of discount).

Therefore, for the first discount we get: \((200) (100\% – 15\%) = (200) (0.85)\)

For the next \(15\%\) discount: \((200) (0.85) (0.85)\)

14- **C**

Compare each mark:

In Algebra Joe scored 20 out of 25 in Algebra. It means Joe scored \(80\%\) of the total mark.

\(\frac{20}{25}=\frac{x}{100}⇒x= 80%\)

Joe scored 30 out of 40 in science. It means Joe scored \(75\%\) of the total mark.

\(\frac{30}{40}=\frac{x}{100}⇒x= 75%\)

Joe scored 68 out of 80 in mathematics which means \(85\%\) of the total mark.

\(\frac{68}{80}=\frac{x}{100}⇒x= 85%\)

Therefore, his score in mathematics is higher than his other scores.

15- **12**Use the volume of the triangular prism formula.

\(V =\frac{1}{2} (length) (base) (high)\)

\(V = \frac{1}{2} × 4 × 3 × 2 ⇒ V = 12 \space m^3\)

16- **B**

To find the discount, multiply the price by (\(100\% –\) rate of discount).

Therefore, for the first discount we get: \((D) (100\% – 20\%) = (D) (0.80) = 0.80 D\)

To increase the \(10 \%: (0.80 D) (100\% + 10\%) = (0.85 D) (1.10) = 0.88 D = 88\%\) of \(D\)

17- **D**

When a point is reflected over \(x\) axes, the \((y)\) coordinate of that point changes to \((-y)\) while its \(x\) coordinate remains the same.

\(C (7, 9) → C’ (7, -9)\)

18- **B**

Ratio of women to men in city A: \(\frac{570}{600}=0.95\)

Ratio of women to men in city B: \(\frac{291}{300}=0.97 \)

Ratio of women to men in city C: \(\frac{665}{700}=0.95\)

Ratio of women to men in city D: \(\frac{528}{550}=0.96 \)

19- **D**

Percentage of men in city \(A = \frac{600}{1170}×100=51.28% \)

Percentage of women in city \(C = \frac{665}{1365}×100=48.72% \)

Percentage of men in city \(A\) to percentage of women in city \(C =\frac{51.28}{48.72}=1.05 \)

20- **B**

let \(x\) be the number of gallons of water the container holds when it is full.

Then;\(\frac{7}{24}x=3.5→x=\frac{24×3.5}{7}=12\)
