what?
I apologize for the confusion. The correct answer for question 7 is $318.
The answer to question 1 is: The portion of how-to books that are either carpentry or electronics
Question 1: The answer 0.12 represents the portion of how-to books in the library that deal with electronics. To get this answer, we multiply the proportion of how-to books (0.3) by the proportion of how-to books that deal with electronics (0.4).
Question 2: Sara discarded 110 apples as defective out of the 200 apples she picked. The remaining apples were sold as fresh fruit. To find how many apples were sold as fresh fruit, we subtract the number of defective apples (110) from the total number of apples picked (200).
Question 3: The total area of the town of Oak Manor can be found by multiplying its length (3.8 miles) by its width (4.2 miles). This is because the formula for the area of a rectangle is length times width.
Question 4: The basketball player is 623 feet tall, and his infant son is 1/14th as tall. To find the height of his son, we divide the height of the basketball player by the fraction 1/14.
Question 5: The diver is searching for a sunken treasure that is 97.2 feet below the surface. If the diver is 23% of the way down, we multiply the total distance (97.2 feet) by the fraction 23/100 to find the diver's elevation.
Question 6: The diver descends at a rate of 8 m/min. To find her depth after 5 minutes, we multiply her rate of descent (8 m/min) by the number of minutes (5).
Question 7: The kayak initially costs $378. The store reduces the price of the kayak by $15 each month for four months. To find the price of the kayak at the end of four months, we subtract the total reduction in price (4 months * $15/month) from the initial price ($378).
Question 8: The expression 2(-4) can be evaluated by multiplying 2 by -4, which gives us -8. So, the best model that represents the expression 2(-4) is "-8".
