Answer:
D. A cold, dry air mass interacts with a warm, moist air mass.
Step-by-step explanation:
Tornadoes are very scary and kind of cool to look at. They have a great scientific reason behind them which we can easily understand. First, a funnel cloud forms that reaches down to the ground (you probably have seen this in video as a cloud that is heavily densed and circling). Then , warm air rises, resulting in a decrease in air pressure and finally, a cold, dry air mass interacts with a warm, moist air mass.
Okay. That formula is set up like this: (n / 2) + 7 = 10. First, we subtract 7 from both sides. When that is done, you should get n/2 = 3. Next, you must multiply each side by 2 to isolate the “n”. When you do this correctly, you should get 6. If you need to check the answer, plug it in. When we check it, the number works. n = 6.
To do this follow the ADAM steps:
<u>A</u>dd 3 and 2 together = 5
<u>D</u><u />ivide 30 by 5 = 6
<u>A</u>nd...
<u>M</u>ultiply each part of the original ratio by 6. 3x6 = 18 and 2x6 = 12
The answer is 18:12 I think... if that's what you were looking for. :P
$6.60 i think, i subtracted the total ($14.40) with the cost of the beads ($7.80) and came to the remaining cost of $6.60 to be spent
