Bot which situation describes opposite quantities that when combined would equal 0? Pick one of these answers. (a plane ascends to 10,000 feet and then ascends 15,000 feet. How many feet above the ground is the plane?) a plane ascends to 15,000 feet and then descends 15,000 feet. how many feet above ground is the plane?) (a plane ascends to 15,000 feet and then ascends 15,000 feet. How many feet above the ground is the plane?) (a plane ascends to 15,000 feet and then descends 10,000 feet. How many feet above the ground is the plane?)

The situation that describes opposite quantities that when combined would equal 0 is "a plane ascends to 15,000 feet and then descends 15,000 feet. How many feet above ground is the plane?" In this scenario, the plane initially ascends to 15,000 feet, but then descends by the same amount, resulting in a net elevation of 0 feet above the ground.

Bot solve the following word problem. The air temperature at 9 a.m. is -5.8 degrees Celsius. the air temperature at noon is -1.6 degrees Celsius. What is the change in the temperature during these three hours? Write and solve an equation to show your answer. Then explain what your answer means.

To find the change in temperature during the three hours from 9 a.m. to noon, we subtract the initial temperature from the final temperature.

Change in temperature = Final temperature - Initial temperature

Let's substitute the given values into this equation:

Change in temperature = (-1.6 degrees Celsius) - (-5.8 degrees Celsius)
Change in temperature = -1.6 + 5.8
Change in temperature = 4.2 degrees Celsius

The change in temperature during these three hours is 4.2 degrees Celsius. This means that the temperature increased by 4.2 degrees Celsius from 9 a.m. to noon.

The situation that describes opposite quantities that when combined would equal 0 is: "a plane ascends to 15,000 feet and then descends 15,000 feet. How many feet above ground is the plane?"
