Question 1 |

**Franklin bought several kites, each costing 16 dollars. Richard purchased several different kites, each costing 20 dollars. If the ratio of the number of kites Franklin purchased to the number of kites Richard purchased was 3 to 2, what was the average cost of each kite they purchased?**

16.8 | |

17.2 | |

17.6 | |

18.0 |

Question 1 Explanation:

The correct answer is (C).

For every 5 kites purchased by Franklin and Richard, 3 of the kites are Franklin’s and 2 of the kites are Richard’s. We can set up an equation to find the total money spent:

Total money spent for every 5 kites: 3(16) + 2(20) = 88

To find the average cost per kite, we can simply divide 88 by 5:

88 ÷ 5 = 17.6

For every 5 kites purchased by Franklin and Richard, 3 of the kites are Franklin’s and 2 of the kites are Richard’s. We can set up an equation to find the total money spent:

Total money spent for every 5 kites: 3(16) + 2(20) = 88

To find the average cost per kite, we can simply divide 88 by 5:

88 ÷ 5 = 17.6

Question 2 |

**What is the total number of degrees in the interior angles of a regular hexagon?**

720° | |

810° | |

920° | |

1080° |

Question 2 Explanation:

The correct answer is (A).

To find the total number of degrees in the interior angles of any polygon, all we need to know is the total number of sides. Each time we add a side (triangle to quadrilateral, quadrilateral to pentagon, etc), we add another 180° to the total. This can be expressed with the formula:

Sum of Interior Angles = (

Since a hexagon has 6 sides,

Sum of Interior Angles = (6 − 2) × 180 = 4 × 180 = 720°

To find the total number of degrees in the interior angles of any polygon, all we need to know is the total number of sides. Each time we add a side (triangle to quadrilateral, quadrilateral to pentagon, etc), we add another 180° to the total. This can be expressed with the formula:

Sum of Interior Angles = (

*n*− 2) × 180, where*n*is the number of sides.Since a hexagon has 6 sides,

*n*= 6:Sum of Interior Angles = (6 − 2) × 180 = 4 × 180 = 720°

The correct answer is (C). This function translates graphically into a parabola with a vertex at (−½, 0) that is vertically stretched and opens upwards. Only answer choice (C) shows an appropriate possibility.

4(

*x*^{2}+*x*+ $\frac{1}{4}$) = 4(*x*+ $\frac{1}{2}$)^{2})The correct answer is (C). This function translates graphically into a parabola with a vertex at (−½, 0) that is vertically stretched and opens upwards. Only answer choice (C) shows an appropriate possibility.

Question 4 |

**A birthday cake with a height of 4 inches is cut into two pieces such that each piece is of a different size. If the ratio of the volume of the larger slice to the volume of the smaller slice is 5 to 3, what is the degree measure of the cut made into the cake?**

115° | |

120° | |

135° | |

145° |

Question 4 Explanation:

The correct answer is (C).

Since the ratio of the larger slice to the smaller slice is 5 to 3, the ratio of the area of the smaller slice to the area of the

This ratio is the same as the ratio of the interior angle of the smaller slice to 360° (the entire cake).

We can therefore set up a proportion:

$\frac{3}{8} = \frac{x}{360}$

360(3) = 8

1080 = 8

135 =

Since the ratio of the larger slice to the smaller slice is 5 to 3, the ratio of the area of the smaller slice to the area of the

*entire*cake must be 3 to 8.This ratio is the same as the ratio of the interior angle of the smaller slice to 360° (the entire cake).

We can therefore set up a proportion:

$\frac{3}{8} = \frac{x}{360}$

360(3) = 8

*x*1080 = 8

*x*135 =

**Line**

*x*can be described by the function ƒ(x) = 5*x*. Line*y*is parallel to Line x such that the shortest distance between Line*y*and Line*x*is 5, and the*y*-intercept of Line*y*is negative. What is a possible equation for line*y*?$f(x) = x - 5$ | |

$f(x) + 5\sqrt{2} = 5x$ | |

$f(x) = x - 5\sqrt{2}$ | |

$f(x) - 5 = 5x$ |

Question 5 Explanation:

The correct answer is (B).

Start by drawing the lines:

The slope-intercept form of a line is

The distance between Line

Since the

Thus, the answer is (B).

Start by drawing the lines:

The slope-intercept form of a line is

*y*=*mx*+*b*, where*m*is the slope and*b*is the*y*-intercept. Parallel lines have the same slope, so Line*y*must also have a slope of 5. Therefore, we can eliminate choices (A) and (C).The distance between Line

*x*and Line*y*is 5. If we drew a perpendicular line from the origin to Line*y*, we can form a right triangle with the*y*-axis as the hypotenuse, and the distance between the lines as one of the legs.Since the

*y*-intercept of Line*y*must be negative, we can eliminate choice (D).Thus, the answer is (B).

Question 6 |

**VitaDrink contains 30 percent concentrated nutrients by volume. EnergyPlus contains 40 percent concentrated nutrients by volume. Which of the following represents the percent of concentrated nutrients by volume in a mixture of**

*v*gallons of VitaDrink,*e*gallons of EnergyPlus, and*w*gallons of water?$$\dfrac{v+e}{v+e+w}$$ | |

$$\dfrac{0.3v+0.4e}{v+e+w}$$ | |

$$\dfrac{3v+4e}{v+e+w}$$ | |

$$\dfrac{30v+40e}{v+e+w}$$ |

Question 6 Explanation:

The correct answer is (D).

The total number of gallons in the final mixture will be the sum of all the components:

There are 0.3

The total number of gallons of nutrients in the new mixture will be 0.3

To convert from a fraction to a percent, we simply multiply our value by 100:

$100 * \dfrac{0.3v + 0.4e}{v + e + w} = \dfrac{30v + 40e}{v + e + w}$

If you chose (B), remember that the question was asking for the percent, not the actual number in the mixture!

**What is the sum of the areas of the three rectangles that are drawn below the graph of the line y = 2**

^{x}?6 | |

12 | |

14 | |

16 |

Question 8 Explanation:

The correct answer is (C).

Start by plugging

Since we know each rectangle is 1 space apart, we can then find each area.

The areas are:

2(1) = 2

4(1) = 4

8(1) = 8

Adding up the areas, we get 2 + 4 + 8 = 14.

Start by plugging

*x*= 1,*x*= 2, and*x*= 3 into the equation*y*= 2^{x}. This will determine the y-coordinates where the corner of each rectangle touches*y*= 2^{x}. Those y-values will be the height of each rectangle.Since we know each rectangle is 1 space apart, we can then find each area.

The areas are:

2(1) = 2

4(1) = 4

8(1) = 8

Adding up the areas, we get 2 + 4 + 8 = 14.

Question 9 |

**If AB is parallel to**

*DC*, and*AD*is parallel to*BC*, then what is the value of*b*−*a*?30° | |

50° | |

60° | |

70° |

Question 9 Explanation:

The correct answer is (B).

If AB is parallel to DC, then BD is a transversal. Alternate interior angles between two parallel lines cut by a transversal are equal.

∠BDC = ∠ABD, so a = 30°.

The sum of the interior angles of a triangle is 180°, so we can write the equation below:

$a + b + 70° = 180°$

$a + b = 110°$

$(30°) + b = 110°$

$b = 80°$

Substitute the determined values and evaluate $b − a = 80° − 30° = 50°$

If AB is parallel to DC, then BD is a transversal. Alternate interior angles between two parallel lines cut by a transversal are equal.

∠BDC = ∠ABD, so a = 30°.

The sum of the interior angles of a triangle is 180°, so we can write the equation below:

$a + b + 70° = 180°$

$a + b = 110°$

$(30°) + b = 110°$

$b = 80°$

Substitute the determined values and evaluate $b − a = 80° − 30° = 50°$

First evaluate the function at

*s*= 7. From this value, evaluate the function at*s*= 3, and then find the difference between the two:*z*(7) = (7)^{2}+ 2(7) = 63*z*(3) = (3)^{2}+ 2(3) = 15*z*(7) −*z*(3) = 63 − 15 = 48, which is answer choice (D).Question 11 |
