A treasure map is drawn to a scale of 2 inches = 3 miles. On the map, the distance between Point A and X-marks-the-spot is 9 ^{1}/_{2} inches. How many actual miles does this represent.
Correct Answer
B. $ 29
Explanation
The scale of the map is 2 inches = 3 miles. Therefore, to find the actual distance represented by 9 1/2 inches on the map, we can set up a proportion. 2 inches is to 3 miles as 9 1/2 inches is to x miles. Solving this proportion, we find that x = (9 1/2 inches * 3 miles) / 2 inches = 14 1/4 miles. Therefore, the correct answer is $29, as it is the closest option to 14 1/4 miles.

3: A house contains one 12-foot-×-14-foot bedroom, one 12-foot-×-10-foot bedroom, and one 8-foot-×-12-foot bedroom. What’s the total amount of carpeting needed to carpet all three bedrooms?
Correct Answer
D. B. 42 2/3 square yards
Explanation
The total amount of carpeting needed can be found by calculating the area of each bedroom and then adding them together. The area of the first bedroom is 12 ft x 14 ft = 168 square feet. The area of the second bedroom is 12 ft x 10 ft = 120 square feet. The area of the third bedroom is 8 ft x 12 ft = 96 square feet. Adding all three areas together gives a total of 384 square feet. To convert this to square yards, divide by 9 (since there are 9 square feet in a square yard). Therefore, the total amount of carpeting needed is 384 square feet / 9 = 42 2/3 square yards.

A bricklayer charges $8 per square foot to lay a patio. How much would it cost for the bricklayer to lay a 12-foot-×-16-foot patio?
Correct Answer
A. $1536
Explanation
To find the cost of laying the patio, we need to calculate the area of the patio first. The area of a rectangle can be found by multiplying its length by its width. In this case, the length of the patio is 12 feet and the width is 16 feet. Therefore, the area of the patio is 12 feet * 16 feet = 192 square feet. Since the bricklayer charges $8 per square foot, we can find the total cost by multiplying the area of the patio by the cost per square foot. So, 192 square feet * $8 per square foot = $1536. Therefore, it would cost $1536 for the bricklayer to lay a 12-foot-by-16-foot patio.

Your piggy bank contains $19.75 in dimes and quarters. There are 100 coins in all. How many dimes are there?
Correct Answer
A. 35
Explanation
Since there are 100 coins in total and the value of each coin is either 10 cents (dime) or 25 cents (quarter), we can set up a system of equations to solve for the number of dimes. Let's say the number of dimes is represented by "d" and the number of quarters is represented by "q". We know that d + q = 100 (since there are 100 coins in total) and that 10d + 25q = 1975 (since the total value of the coins is $19.75). Solving this system of equations, we find that d = 35. Therefore, there are 35 dimes in the piggy bank.
