### In trail mix, the ratio of cups of peanuts to chocolate candies is 3 to 2. How many cups of chocolate candies would be needed for 9 cups of peanuts?

• A.

6 cups

• B.

3 cups

• C.

4 cups

• D.

8 cups

A. 6 cups
Explanation
The ratio of cups of peanuts to chocolate candies in trail mix is 3 to 2. This means that for every 3 cups of peanuts, there are 2 cups of chocolate candies. To find out how many cups of chocolate candies would be needed for 9 cups of peanuts, we can set up a proportion. If 3 cups of peanuts require 2 cups of chocolate candies, then 9 cups of peanuts would require x cups of chocolate candies. Solving the proportion, we find that x = (9 * 2) / 3 = 6. Therefore, 6 cups of chocolate candies would be needed for 9 cups of peanuts.

### The seventh grade class is going on a trip to the state fair. The trip costs \$52. Included in that price is \$11 for a concert ticket and the cost of two passes, one for rides and one for game booths. Each of the passes cost the same price. Write an equation representing the cost of the trip and determine the price of one pass.

• A.

2x â€“ 11 = 52; \$31.50

• B.

3x = 52; \$17.33

• C.

2x = 52; \$26

• D.

52 = 11 + 2x; \$20.50

D. 52 = 11 + 2x; \$20.50
Explanation
The equation 52 = 11 + 2x represents the cost of the trip. The left side of the equation represents the total cost of the trip, which is \$52. The right side of the equation represents the sum of \$11 for the concert ticket and the cost of two passes, which are both represented by 2x. By subtracting 11 from both sides of the equation, we can isolate the variable 2x. Therefore, the price of one pass is \$20.50.

### A rectangle has vertices P(1, 0), Q(6, 0), R(6, 6), and S(1, 6).What is the area of rectangle PQRS?

C.
Explanation
To find the area of a rectangle, we can use the formula: Area = length Ã— width. In this case, the length of the rectangle is the distance between points P(1, 0) and Q(6, 0), which is 6 - 1 = 5 units. The width of the rectangle is the distance between points P(1, 0) and S(1, 6), which is 6 units. Therefore, the area of rectangle PQRS is 5 Ã— 6 = 30 square units.

### If a rectangle, measuring 2 in. by 7 in., is enlarged by using a scale factor of 2, what will the area be of the new rectangle?

• A.

56

• B.

28

• C.

14

• D.

98

A. 56
Explanation
When a rectangle is enlarged using a scale factor of 2, all of its dimensions are multiplied by 2. In this case, the length of the rectangle is 2 inches and the width is 7 inches. When we multiply both of these dimensions by 2, we get a new rectangle with a length of 4 inches and a width of 14 inches. To find the area of this new rectangle, we multiply the length by the width: 4 inches * 14 inches = 56 square inches. Therefore, the area of the new rectangle is 56.

### Solve the following inequality. -0.5x - 5  -1.5

• A.

X   -7

• B.

X   7

• C.

X   7

• D.

X   -7

D. X   -7
Explanation
The given inequality is -0.5x - 5 â‰¤ -1.5. To solve this inequality, we need to isolate the variable x. We can do this by adding 5 to both sides of the inequality, which gives -0.5x â‰¤ -1.5 + 5. Simplifying further, we get -0.5x â‰¤ 3.5. To isolate x, we divide both sides of the inequality by -0.5. However, when dividing by a negative number, the direction of the inequality changes. Therefore, we have x â‰¥ -7. So, the correct answer is x â‰¥ -7.

### The Irrational Club wants to build a tree house. They have a 13-foot ladder that must be propped diagonally against the tree. If the base of the ladder is 5 feet from the bottom of the tree, how high will the tree house be off the ground?

• A.

12 feet

• B.

144 feet

• C.

169 feet

• D.

14 feet

A. 12 feet
Explanation
The ladder forms a right triangle with the ground and the height of the tree house. Using the Pythagorean theorem (a^2 + b^2 = c^2), where a is the height of the tree house, b is the distance from the base of the ladder to the bottom of the tree, and c is the length of the ladder, we can solve for a. Plugging in the given values, we have a^2 + 5^2 = 13^2. Simplifying, we get a^2 + 25 = 169. Subtracting 25 from both sides, we have a^2 = 144. Taking the square root of both sides, we get a = 12. Therefore, the tree house will be 12 feet off the ground.

### Write the equation of a line, in slope-intercept form, passing through the points (6, 2) and (3, 0).

A.
Explanation
The slope-intercept form of a line is given by y = mx + b, where m is the slope and b is the y-intercept. To find the slope, we can use the formula: m = (y2 - y1) / (x2 - x1). Substituting the values of the given points, we get m = (0 - 2) / (3 - 6) = -2 / -3 = 2/3. Now, we can substitute the slope and one of the points into the equation to find the y-intercept. Using the point (6, 2), we get 2 = (2/3)(6) + b. Solving for b, we find b = 2 - 4 = -2. Therefore, the equation of the line is y = (2/3)x - 2.

Rate this question:

• 35.

### Which is the graph of the function y = 4x – 1?

C.
Explanation
The graph of the function y = 4x - 1 is a straight line with a slope of 4 and a y-intercept of -1. The slope of 4 means that for every increase of 1 in the x-coordinate, the y-coordinate increases by 4. The y-intercept of -1 means that the line crosses the y-axis at the point (0, -1). Therefore, the correct answer is the graph that represents a straight line with a slope of 4 and a y-intercept of -1.
