Answer:
Our expression is 205+2d where d is days past 60.
Step-by-step explanation:
Since the sunflower is 205 centimeters at 60 days, every day after 60 will be greater than 205. We will start with 205 in our expression.
205
Now, each day after 60 the sunflower grows 2 centimeters per day. So day 61 will be:
205+2
Day 62 will be:
205 +2+2
Notice, that for two days past 60, the sunflower has grown 2 times as much.
Our expression is 205+2d where d is days past 60.

First you subrtract 3 from 0 then add 4 to -3
Answer:
C 180-123
Step-by-step explanation:
This is because 180 is what triangles always equal and if one angle is 128 then the rest will be answered from this equation
Answer:
Step-by-step explanation:
200(1+r)⁵⁻³ = 200(1+r)² = 800
(1+r)² = 4
1+r = 2
r = 100%
800(1+r)⁷⁻⁵ = 800·2² = 3200
Answer:
79% - almost 4 times out of 5.
The key to this is realizing that the number of games will not always be 5.
If A wins in a sweep - you have 2/3*(2/3)*2/3 percent chance of that happening - 8/27, or 29.63%
If A wins in 4, now we have 2/3*(2/3)*2/3*(1/3)*3 - the 1/3 is the chance that B wins a game. Note - there are only 3 ways B can win a game, not 4. B cannot win Game 4 because Game 4 would not be played in case of a sweep. That is why you cannot use a straight Pascal’s triangle to get your coefficients - the 1–4–6–4–1 is not possible if B cannot win Game 4. Anyway, the math is the same as the above, a 29.63% chance of A winning in 4.
For a 5 game set, A could lose 2 games in 6 possible ways (lose 1&2, 1&3, 1&4, 2&3, 2&4 or 3&4). Again, A cannot lose Game 5 - it would not be played once A wins 3 games. So the odds become 2/3*(2/3)*2/3*(1/3)*(1/3)*6, or 19.75%.
Add them up and you get 79.01%
