## Answers:

1- **C**

\(6\) quarters \(= 6 × 25\) pennies \(=150\) pennies

\(9\) dimes \(= 9 ×10 \)pennies \(= 90\) pennies

In total Nicole has 251 pennies

2- **A**

\(1\) issue\(= $4\)

How many issue? \(= $72\)

\($72 ÷ $4= 18\) issue

3-** C**

Use perimeter of triangle formula.

\(P = a + b + c\)

\(P = 12 + 15 + 16 = 43\) inches

4- **C**

Use perimeter of rectangle formula.

\(P = 2(L + W)\)

\(60 = 2(10+W) ⇒ 2W = 40 ⇒ W = 20 \)feet

5- **B**

An obtuse triangle is one with one obtuse angle (greater than 90\(^\circ\)) and two acute angles. Since a triangle’s angles must sum to 180\(^\circ\), no triangle can have more than one obtuse angle.

6- **C**

\(1\) foot \(= 0.333 \)yard

So \(36\) foot \(= 12\) yards \((36 × 0.33)\)

7- **B**

The sum of \(A\) and \(B\) equals \(35: A + B = 35\), if \(A = 16\) we have \(16 +B = 35\)

8- **D**

\(A = 108 ÷ 9 = 12\)

9- **B**

Sum of these three angle are 180\(^\circ\).

\(A^\circ + 80^\circ + 16^\circ = 180^\circ\)

\(A^\circ =180^\circ – 96^\circ = 84^\circ\)

10- **C**

Use perimeter of trapezoid formula.

\(P = a + b + c + d\)

\(P = 2+ 6 + 2+ 8 =18\)

11- **B**

Low temperature is 24\(^\circ\)f cooler than the temperature at 12:00 PM that is 76of, that means low temperature is 52\(^\circ\)f (76\(^\circ\)f \(–\) 24\(^\circ\)f) that is close to choice B

12- **A**

\((4 × 10) + (7 × 1) + (6 × 0.01) = 40 + 7 + 0.06 = 47.06\)

13- **D**

1 year \(=\) 365 days, 1 day \(=\) 24 hours

1 year \(=\) 365 × 24

1 year \(=\) 8,760

14- **B**

Each game = \(\frac{11}{2}\) hours = 90 minutes so 3 games = \(\frac{41}{2}\) hours = 270 minutes

5minutes between each game, so there is 10 minutes in total between 3 games.

She arrives 15 minutes before first game and left 10 minutes after the last game.

In total she was \(270+10+15+10 =305\) minutes at the soccer field.

15- **A**You can find if a shape has a Line of Symmetry by folding it. When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry. Here the first shape shows a line of symmetry.

16- **B**

Find the least common denominator (LCD), then rewriting each term as an equivalent fraction with the LCD. Then we compare the numerators of each fraction and put them in correct order from least to greatest or greatest to least.

LCD of 2, 8, 4 and 16 is 16. Rewrite the input fractions as equivalent fractions using the LCD:

A. \(\frac{8}{16}\)

B. \(\frac{6}{16}\)

C. \(\frac{12}{16}\)

D. \(\frac{9}{16}\)

So choice B has the least value.

17- **D**

12 pastilles\(=\) 1 box

336 pastilles\(=\) (\(336 ÷12 = 28\)) boxes

18- **64**

Use volume of cube formula:

V\(=a^3\)

V\(=4^3 =64\)

19- **C**

Arrow shows exactly the middle of two numbers 25 and 35, so the answer is 30

20- **A**

This shape shows 3 complete shaded triangles and a half of a triangle that is equal to \(3\frac{1}{2}\)
