Answer:
The answer is B
Step-by-step explanation:
When he bought the item he lost 2.25 dollars giving him a net profit of -2.25
When he sold it for 2.25 he gained a net profit of 2.25 which cancels out his negative net profit giving a final product of 0.
Answer: A) (2+2) x 3
Step-by-step explanation: The answer to the problem (2 X 3) + (2 X 3) is 12 so we have to find the eqaution in the answers that equals 12,
B) 2 + (3+3) is equal to 8 so that can't be the correct answer
C) 2 x 3 x 3 is equal to 18 so that can't be the correct answer
D) (2 + 3) x (3+2) simplifies to 5 x 5 which is 25 so that can't be the correct answer
So that leaves us with A) (2+2) x 3 as the correct answer because it equals <u>12</u>
Answer:
2n^2 + n + 4.
Step-by-step explanation:
7, 14, 25, 40, 59
The differences are 7, 11, 15, 19 which is arithmetic sequence so the given sequence is quadratic.
Compile a table:
n 1 2 3 4 5
term 7 14 25 40 59
Diff: 7 11 15 19
Diff: 4 4 4 - this indicates that first part is 2n^2.
2n^2 2 8 18 32 50
term-2n^2 5 6 7 8 9
- the nth term for the last sequence is 5+ (n - 1)d =
= 5 + (n - 1)* 1
= n + 4.
So nth term for the original sequence is 2n^2 + n + 4.
Answer:
14 rainy days were there.
Step-by-step explanation:
Total days = 90.
Rainy days = 2/13
Non rainy days = 11/13
If 90 days = 13 total ratio
? = 2 ratio
(90×2)/13 = 14days.
