Answer:
1) 100
2) 22
3) 39
4) 6
5) 2b + 6
6) 8
7) 4n + 20
Explanation:
If B is the midpoint of AC and C is the midpoint of BD, means that all 3 parts are equal. AB = BC = CD
1) If AB = 50 then AC = AB + BC = 50 +50 = 100
2)if BD = 44 then is CD = 44 - BC ⇔ CD = 44 - 22 = 22
3) if AC = 26 and AC = AB + BC then each part is 13
AD = AC + CD = 26 +13 = 39
4)if CD = 6 then AB = 6 Because all single parts are equal
5) if AC = 4b + 12 then is AB the half of it = 2b +6
6) if AD = 24 then AB = 1/3 of it = 8
7)if BC is 2n + 10 then is AC = 2x BC = 4n + 20
Answer:
Both are only physical changes.
Explanation:
Nothing about the objects chemically change, and they remain the same.
Their changes arent due to heating/cooling.
<span>Since Astatine is in period 7 and Te is in period 6, I'm going with At because it has 7 energy levels.</span>
The correct answer C - acceleration
“Is a percentage of atoms with a specific atomic mass found in a naturally occurring sample of an element.” < you can try and put it in your own words or you could stick with that just add quotations :)
