Answer:
21
Step-by-step explanation:
So, factors of 6 that are between 17 and 25 are 18 and 20, so that's not the numbers.
Multiples of 3 are 18, 21, and 24.
The only number that would be reasonable enough is 21, because it is a multiple of 3 and is not a factor of 6.
Answer: air pressure
Whenever you hear things like "high pressure" or "low pressure" on weather reports, they measured the pressure using a barometer. Knowing the air pressure helps determine if there is a higher chance of rain or storms for instance.
Typically but not always, high pressure correlates to sunny days and dry weather. Low pressure often brings about rain. This is of course a very oversimplified viewpoint.
Answer:
seconds
Step-by-step explanation:
When the ball hits the ground, its height will obviously be 0. Therefore, you can set up the equation the following way:
Plugging this into the quadratic equation, you get:
Since the time must be positive, it takes the ball seconds to hit the ground, or around 3.828. Hope this helps!
