Answer:
A
Step-by-step explanation:
expanding the bracket, we would have
-2x -18 = -x+1+2
-2x+x= 3 +18
-x=21
x=-21
Angle OPM and Angle LMK
When angles are corresponding, they're essentially on the same side. It's sort of hard to explain, so I'll attach a drawing. The one on the left with the check mark is a corresponding angle, and the one on the right with the X is a same-side angle. Essentially, corresponding angles are on the same side and are also equal, unlike same-side angles, which are supplementary angles.
Let me know if you don't understand my explanation.

Answer:
Ending Amount = Beginning Amount / 2 ^ n
where 'n' = number of half-lives n = 65 / 29 = 2.2413793103
Ending Amount = 25 g / 2^2.2413793103
Ending Amount = 25 / 4.7284892286
Ending Amount = 5.2871009727 g = 5.29 g (rounded)

Answer:
%28.57 (14285714286)
Step-by-step explanation:
Divid To get decimal (percent right)
250/350= 0.714285714285714
Subtract from 1 to get decimal (Percent wrong)
1.0 - 0.714285714285714= 0.285714285714286
Move over decimal to placements to the right to convert to percent
%28.5714285714286
Round
%28.57
Answer: 3.6 feet per year
Pick any column and divide the feet over the years
eg: 7.2/2 = 3.6 (column 1)
You can think of it as the ratio
7.2 feet: 2 years
and then divide both sides by 2 to get "1 year" on the right side
7.2 feet: 2 years
7.2/2 feet: 2/2 years
3.6 feet: 1 year
