Here's a review of the questions and your answers:
1. 2/3 * negative 6 * 5
Your answer: -100
The correct answer is -20. To solve this, multiply -6 by 5 to get -30. Then, multiply -30 by 2/3 to get -20.
2. A landscaper installs 12 sections of trellis. Each section of trellis is 3/4 yard long. How many yards of trellis are installed altogether?
Your answer: 9 yards of trellis are installed altogether
The correct answer is 9 yards. To find the total length of trellis, multiply the number of sections (12) by the length of each section (3/4). This gives us 12 * 3/4 = 36/4 = 9 yards.
3. A biologist uses a box-shaped fish trap that measures 1/4-meter by 2/3-meter by 3/5-meter. What is the volume of the trap in cubic meters?
Your answer: 1/10-meters^3 is the volume of the trap
The correct answer is 1/120 cubic meters. To find the volume of a box-shaped object, multiply the three dimensions together. So, 1/4 * 2/3 * 3/5 = 1/120 cubic meters.
4. The temperature at noon is 75 degrees Fahrenheit. The temperature drops 3 degrees every half hour. What is the temperature at 4 p.m.?
Your answer: The temperature at 4 p.m. is 51 degrees Fahrenheit
To find the temperature at 4 p.m., we need to determine how many half-hour intervals there are from noon to 4 p.m., and then subtract the appropriate amount from 75 degrees. There are 4 intervals of half hours from noon to 4 p.m. So, 75 - (4 * 3) = 75 - 12 = 63 degrees Fahrenheit. Thus, the correct answer is 63 degrees Fahrenheit.
